Stick With Whole Grains

Monday, June 14th, 2010

Why in the world would someone take whole wheat grain, crack the grain, pulverize it with rollers, and separate the endosperm from the dark, fibrous bran and the wheat embryo?  Why would they take out important nutrients, vitamins, unsaturated fats, fiber and magnesium?  And if intact grains are so healthy, why did we stop eating them and shift to highly refined grains? 

White flour was a novelty for the upper classes.  The fact that you could take this brown, grainy flour and “purify” it also helped make bread and cakes lighter, airier and fluffier.  Buying white flour became a status symbol.  White flour can also survive longer without refrigeration.  But the damage we have done to ourselves in the process has been severe. 

Whole grains protect against diabetesAccording to two large ongoing studies, people who consume whole grains are 30% less likely to develop diabetes.  Because whole grains take longer to digest, you don’t get repeated insulin spikes, which lead to Type II diabetes. 

Intact grains mean less heart disease.  Also according to a large study, women who consume more whole grains were 30% less likely to develop heart disease than those who consumed refined grains.   

Less refined grains mean better GI health.  The fiber in whole grains helps keep the stool soft and bulky.  This prevents constipation, which is the number one gastrointestinal complaint in the United States.  725 million dollars is spent annually on over-the-counter laxatives. Whole grains also help to prevent diverticulitis and diverticulosis.

Whole grains may prevent cancer.  A recent overview of 40 control studies indicated that whole-grain consumption reduced the chances of developing mouth, stomach, colon, gallbladder and ovarian cancer. 

Be sure the products you are buying are truly whole-grain.  Often, breads are brown in color, but are made with white processed flour.  Check the ingredients to be sure.  If the taste of a whole-grain food like pasta or brown rice isn’t palatable to you, begin by mixing it with the white refined version and slowly increasing the ratio of intact grains to refined grains.  Remember – the more any food is processed, the more nutrients and vitamins are lost.   

Whereas at one time, you could only find whole wheat, whole rye, brown rice and whole grain pasta in health food stores, now they are available just about everywhere.  According to the USDA, only 1% of ingested energy in the United States is unrefined as opposed to 20% for refined grains.  Studies suggest that the more this ratio changes in favor of whole grains, the less disease there will be.  Once you make the change, you will realize how much natural flavor and taste are in whole grains and you may never want that piece of white bread again.   

Eating whole, unrefined grains is another way to “add hours to your day, days to your year and years to your life.”

Genetic Study Sheds Light On Jewish Diaspora

Thursday, June 10th, 2010

It also revealed genetic ties between globally dispersed Jews and non-Jewish populations in the Middle East.

This fits with the idea that most contemporary Jews descended from ancient Hebrew and Israelite residents in the Middle Eastern region known as the Levant. It provides a trace of the Jewish diaspora.

Doron Behar from Rambam Health Care Campus in Haifa, Israel, led an international team of scientists in the study. He described it as a form of “genetic archaeology”.

“It seems that most Jewish populations and therefore most Jewish individuals are closer to each other [at the genetic level], and closer to the Middle Eastern populations, than to their traditional host population in the diaspora,” he explained.

There were exceptions to this key finding, though, as Dr Behar explained.

He said that his research revealed that Ethiopian and Indian Jewish communities were genetically closer to their neighbouring non-Jewish populations.

This may be partly because a greater degree of genetic, religious and cultural crossover took place when the Jewish communities in these areas became established.

Novel analytical techniques allowed the scientists to examine the genetic samples they took in unprecedented detail.

Dr Behar says the data from this study could aid future research into the genetic basis of diseases that are more prevalent in the Jewish population.

The Cost of Poor Health

Monday, June 7th, 2010

The two most common excuses people give for not exercising and taking care of their general health are lack of time, and finances. In previous articles, I have addressed the time issue, but I would like to add the following: If you don’t make the time to exercise, you won’t have much time to do anything. Eventually, as we age and don’t make the time to compensate for its effects, we end up with one or more debilitating condition. But what is just as shocking is how much it actually costs us to be out of shape and in an unhealthy state. Many people say they just can’t afford to go to an exercise specialist, or they can’t afford the health club and gym fees. But let’s look at the alternative.

Take a person with heart disease, for example. Cardiovascular disease is the leading cause of death, and multiple medications are often needed to control symptoms and risk factors. In a recent study following 104 people with ischemic heart disease, average monthly medication costs were $104.77 for cardiac medications and $115.54 for non-cardiac medications, for a total of $220.31. In addition, the cost of heart disease and stroke in the United States was $368 billion in 2004, including health care expenditures and lost productivity from disability and death.

If you are an employer, you may want to insist that your employees exercise. In 1995, Nicolaas Pronk, director of HealthPartners’ Center for Health Promotion, surveyed nearly 6,000 HealthPartners members over age 40 about their lifestyle and health status, and then looked at 18 months’ worth of their medical claims. In a report based on that data, published in the Journal of the American Medical Association (JAMA), he compared people with poor habits to those with healthy ones and found that:

Those who engaged in some kind of physical activity at least once a week cost the company 4.7% less than those who are sedentary.
Smokers cost the company 18% more than nonsmokers.
Each unit increase in body mass index (a measure of body fat) raised costs by 1.9%.
Those who suffered from the chronic illnesses that are often the result of unhealthy lifestyles – particularly diabetes and heart disease – were the costliest of all. Diabetics cost 137% more than non-diabetics, and those with heart disease cost 150% more than those without, the study found. 

Obesity and sedentary lifestyle are escalating global epidemics that warrant increased attention by physicians and other health care professionals. These intricately linked conditions are responsible for an enormous burden of chronic disease, impaired physical function and quality of life, at least 300,000 premature deaths, and at least $90 billion in direct health care costs annually in the United States alone. Couple all this with the rising premiums for good comprehensive health insurance and it becomes obvious that it pays to work out and be healthy.

Yes – it CAN be costly to take on a trainer or join a health club, but it’s definitely money well spent. Investing in staying in shape and improving your overall lifestyle habits may, in the long run, be less costly to your health AND to your wallet. 

EXERCISE! It will “add hours to your day, days to your year and years to your life.”

WHO: H1N1 Not Gone Yet

Thursday, June 3rd, 2010

You may have forgotten about the virus formerly known as swine flu, but it hasn’t gone away, according to the World Health Organization.

The agency is continuing its pandemic alert for 2009 H1N1 influenza, WHO chief Margaret Chan announced Thursday in a statement. There are still world regions, particularly in tropical regions such as the Caribbean and Southeast Asia, that have relatively low level of resurgence of cases.

But “the period of most intense pandemic activity appears likely to have passed for many parts of the world,” the statement said.

In July, a WHO committee will meet again to reassess the situation.

More Cancer-Causing Chemicals in U.S. Cigarettes

Tuesday, June 1st, 2010

American cigarettes could pack a more toxic punch than foreign brands, say researchers at the U.S. Centers for Disease Control and Prevention.

In one of the first studies of its kind, researchers compared the levels of tobacco-specific nitrosamines — a main carcinogenic component of tobacco — in cigarette butts and in smokers from several countries.

The result: “All cigarettes are not the same, and cigarettes across countries do not deliver the same amount of carcinogens to people,” said Dr. Jim Pirkle, deputy director for science at the CDC’s National Center for Environmental Health’s Division of Laboratory Sciences.

In fact, the amount of tobacco-specific nitrosamines (TSNAs) in U.S. brands is about triple that of brands from Australia, Canada or the United Kingdom, he said.

Pirkle was not involved in the study, which was led by researcher David Ashley from the same office at the CDC. The study authors stressed that even though TNSA levels may vary brand to brand, all cigarettes are unsafe.

Still, the new findings should help the FDA as it fulfills its new responsibilities overseeing tobacco products, Pirkle said. “This is a major effort for them and they need to understand the different levels of carcinogens that people are exposed to, as they vary by different cigarette brands,” he said.

The report is published in the June issue of Cancer Epidemiology Biomarkers & Prevention.

Cigarette tobacco varies both by manufacturer and where the product is made. For example, American brands use the so-called “American blend” tobacco, which contains higher levels of TSNAs than cigarettes from Australia, Canada or the U.K., according to the researchers.

In those other countries, cigarettes are made from “bright” tobacco, which is lighter in color and flue-cured. This process makes cigarettes with lower levels of TSNA, the team explained.

U.S. brands tested in the study included Marlboro, Newport, Newport Light, Camel Light and Marlboro Menthol. The researchers tested TSNA levels in 126 smokers from Australia, Britain, Canada and the United States. These smokers smoked a variety of popular brands, Ashley’s team noted.

By measuring chemicals in cigarette butts after a day of smoking, the researchers were able to determine how much TSNA smokers were exposed to. In addition, they also used urine samples to find out how much of the TSNA was broken down in the body.

They found a correlation between the amount of TSNA that entered a smoker’s body and how much is broken down in the urine. “We will be able to use this biomarker in the urine to help us understand how much of the carcinogen exposure you are getting in your mouth and lungs,” Pirkle said.

Danny McGoldrick, vice president for research at the Campaign for Tobacco-Free Kids said the study “shows why the authority to issue product standards, which the U.S. Food and Drug Administration [FDA] now has, is critically important.”

This type of research will help determine changes in the design of tobacco products, he said. These changes could include “reducing TSNAs in cigarettes, which will benefit public health,” McGoldrick said.

If the FDA determines that reducing the levels of TSNAs would be a public health benefit, then it could mandate a change in all tobacco products on the market, McGoldrick added.

“This is a dramatic change from the days when the only people who had anything to say about tobacco product design were the tobacco companies, and they of course had no interest and have no interest in public health,” he said.

Another expert said even that is not enough to protect the public’s health.

“There are two things in the paper that are disturbing to me,” said Dr. Norman Edelman, chief medical officer for the American Lung Association. “First, it seems as if U.S. smokers get more exposure to this deadly carcinogen than smokers in other countries. Second, there is the oblique suggestion that it might be worthwhile to try to reduce the levels of this carcinogen in tobacco smoke. This smacks of suggesting we make cigarettes ‘safer.’ However, there are dozens of carcinogens in cigarette smoke. There is no reason to believe that reducing one will make smoking safer. The only way to prevent cancer from smoking is to prevent smoking. Even hinting about making cigarettes safer is playing into the hands of the tobacco industry’s campaign to promote ‘harm reduction,’ a thinly veiled attempt to keep up the sales of this deadly and totally unnecessary product.”

David Sutton, a spokesman for tobacco giant Philip Morris USA, said the finding was not surprising.

“Previous studies have shown global differences in TSNA levels due to variations in tobacco blending and curing practices around the world,” Sutton said in a statement.

“The company is aware of the concerns about TSNAs. For a number of years we have worked to reduce TSNA levels,” he added. “The FDA now has comprehensive regulatory authority over cigarettes. Under FDA regulation, there is now a regulatory structure to evaluate potential reduced harm products. As of today, however, there is no cigarette on the market that public health organizations endorse as offering ‘reduced risk.’ If smokers are concerned about the risks of cigarette smoking, the best thing to do is quit.”

Health: Lower Back Pain

Monday, May 31st, 2010

After headaches, lower back pain is the second most common ailment in the Western World today.  At least 60-80% of the general population will experience at least one episode of lower back pain in their lives that may range from a dull ache to a bout of intense and prolonged pain.  Not only is it painful; it is costly as well.  Billions of dollars are paid in compensation and lost workdays, many of which are the result of on-the-job injuries.

LBP (low back pain) typically is located in the lumbar region of the spine, with L4 and L5 being the most common place.  Undoubtedly, you have probably heard of slipped, herniated, shattered, protruding and crushed disks.  These are some of the ramifications of LBP, but, what brings on these conditions in the first place and how can they be prevented and/or corrected?

The main causes of LBP are weak abdominal muscles, tight hamstring muscles, poor posture and stress.  Many times, a biomechanical dysfunction resulting from flat feet is the cause.  Also, a simple thing like a worn out pair of shoes can bring on back discomfort.  Prevention of LBP includes a well-balanced exercise program that includes flexibility training (stretching) and abdominal strengthening.  A pair of good, functional orthodics can correct a biomechanical problem.  And amongst its many benefits, aerobic exercise is known to be a great stress reducer.  Being overweight is also a risk factor, as is smoking.

Many years ago, the common thinking on how to treat LBP was to prescribe bed rest.  There is now strong evidence that this treatment is ineffective. It has been shown in studies that bed rest of more than 2-4 days can start to weaken muscles and actually delay recovery.  The current thinking is that a person with LBP should be physically active. Walking, even if somewhat painful, is considered to be essential.

Many people opt for surgery to try to alleviate lower back pain.  But before you go under the knife, consider the following. Surgery helps only 1 in 100, and certainly should not be an option in the first 3 months of pain, notwithstanding a firm diagnosis of a fracture or dislocation.  Spinal manipulation by a chiropractor or physical therapist may be helpful, but no evidence exists to indicate that either ultrasound or traction is helpful.  Although some people feel relief through acupuncture and massage, there is still no scientific evidence to support this as of yet.

A few tips to keep yourself pain-free:

Watch your posture while sitting.  Keep both feet on the floor in front of you and look straight ahead.  This is especially important at the computer.
When standing or walking, look ahead. This will prevent your head from hanging down. Don’t slouch your shoulders and lower back. 
Use a comfortable but firm straight-backed chair.
Make sure your mattresses are in good shape.  Old, worn out mattresses can contribute significantly to back problems

Keeping your lower back functional and free of pain is another way to “add hours to your day, days to your year and years to your life.”

More Children’s Medicine Made at J&J Facility Is Recalled

Saturday, May 29th, 2010

Four children’s cough and cold medicines made at a Johnson & Johnson plant shuttered because of manufacturing problems were recalled Friday, a month after different kids’ medicines made at the facility were withdrawn.

Blacksmith Brands, which sells the PediaCare cough and cold medicines made at the plant in Fort Washington, Pa., said on its website that it was issuing the recall for precautionary reasons. It said it hasn’t received any complaints or reports of side effects connected to the PediaCare products.

The new recall, which a Blacksmith Brands spokesman said affects at most 100,000 bottles, comes a day after Johnson & Johnson was grilled at a congressional hearing over manufacturing lapses at the plant and how its McNeil Consumer Healthcare unit has handled recalls of over-the-counter medicines.

The latest recall affects PediaCare’s Multi-Symptom Cold, Long Acting Cough, Decongestant, and Allergy and Cold medicines. Blacksmith Brands said it has told retailers to take the four products from store shelves and advised parents to stop using the bottles.

The four PediaCare medicines had been owned by J&J, which sold them to Blacksmith Brands in November along with several other over-the-counter consumer products. That was after regulators found several violations of good-manufacturing practices at the Fort Washington plant. The private-equity firm Charlesbank Capital Partners formed Blacksmith, of Tarrytown, N.Y., shortly before the purchase of the products. Blacksmith had long planned for two other manufacturing plants to take over production of its PediaCare products starting in July, a spokesman said.

In an interview Friday before the Blacksmith Brands announcement, Rep. Edolphus Towns (D., N.Y.), chairman of the House Oversight and Government Reform Committee, vowed to step up a probe of the J&J unit’s history of handling defective drugs, indicating the company faces protracted public scrutiny of its manufacturing problems.

Rep. Towns said he wanted to investigate McNeil’s role in a contractor’s apparent effort in late 2008 to buy up defective Motrin pills off retail shelves. Regulators discovered the contractor’s work, and the company issued a recall in July 2009.

A McNeil spokeswoman said the company also planned to look into the contractor’s work and report back to the committee.

The Oversight Committee hearing was called as a result of the McNeil unit’s recall on April 30 of certain Benadryl, Motrin, Tylenol and Zyrtec medicines for infants and children. The Food and Drug Administration says that recall, though not posing much of a safety risk, indicated systemic compliance problems inside J&J’s McNeil unit.

Mr. Towns said the committee would continue investigating the problems and also wants to examine whether the FDA needs more staff and the power to order a recall. Now, companies must volunteer to conduct a recall. The committee also wants to make sure the recent recall was aggressive enough, Rep. Towns added, expressing concern that some parents might not have gotten the message after the company announced the action late on a Friday.

“We cannot take this lightly, and I want J&J to know we are not,” Rep. Towns said.

The unnamed contractor’s work involving defective Motrin emerged during the hearing when lawmakers cited FDA documents and a memo from the contractor to its workers.

The McNeil unit hired the contractor after discovering in late 2008 that some Motrin wasn’t dissolving correctly, according to the materials. The company told the FDA it had hired the contractor for statistical sampling, the FDA documents said.

Colleen Goggins, world-wide chairwoman of J&J’s consumer group, told lawmakers the New Brunswick, N.J., company kept the FDA fully informed of its actions and didn’t have “any intent to mislead or hide anything.” She said she didn’t know what the McNeil unit told the contractor to do.

Experts Advise At-Risk Diabetics to Begin Daily Aspirin Later

Friday, May 28th, 2010

Three major medical groups have pushed upwards the recommended age at which diabetics should start taking low-dose aspirin to prevent a first heart attack or stroke.

According to a joint statement by the American Heart Association, the American Diabetes Association and the American College of Cardiology, only male diabetics over 50 and female diabetics over 60 who are at risk for a heart attack or stroke should be taking aspirin as a preventive.

“Previously, the American Diabetes Association (ADA) recommended aspirin to prevent heart attacks and stroke in most people with diabetes over the age of 40,” noted statement co-author Dr. M. Sue Kirkman, senior vice president for medical affairs and community information at the ADA. However, “more recent studies suggest that the benefits of aspirin are modest, and that aspirin likely would be best for people at very high risk of cardiovascular disease,” she said.

The experts defined an “increased risk of cardiovascular disease” in this case as a 10 percent risk of experiencing a heart attack and/or stroke over the next 10 years.

That means that, “those adults with diabetes at increased risk include most men over age 50, and women over age 60, who have one or more of the following additional major risk factors: smoking, hypertension, high cholesterol or a family history of premature cardiovascular diseases,” Kirkman explained.

According to the U.S. Centers for Disease Control and Prevention, people with diabetes are at three times the increased risk of cardiovascular events compared with people without diabetes. Among diabetics over 65, it’s estimated that 68 percent will die from heart disease and 16 percent from stroke.

On the other side of the equation, the major adverse effects of long-term aspirin use include intracranial bleeding, which can lead to hemorrhagic stroke, and gastrointestinal bleeding.

Still, daily low-dose aspirin — the study authors suggest 75 to 162 milligrams — can have real benefits in preventing cardiovascular events, another expert said.

“Taking low-dose aspirin to prevent heart disease is reasonable for adults with diabetes who are at increased risk of cardiovascular disease and not at increased risk for bleeding,” said the statement’s senior author, Dr. Michael Pignone, chief of the general medicine division and professor of medicine at the University of North Carolina.

“Aspirin should not be recommended for heart disease prevention in men and women at very low cardiovascular risk — under 5 percent over 10 years,” he added.

“People with diabetes should talk to their physicians about their cardiovascular risk and what they should be doing to try to reduce it to a manageable level,” Pignone said. “This includes the decision about aspirin, but also blood pressure control, [cholesterol-lowering] statins, and smoking cessation.”

The clarification of aspirin use among diabetics is being made because the evidence regarding the benefit of aspirin in preventing a first heart attack or stroke has been mixed, the experts said.

Most important, health care professionals should consider diabetic patients’ absolute level of risk before recommending aspirin, Kirkman said.

“For those at relatively low risk, the risks of aspirin probably outweigh the potential benefits. For those at high risk, aspirin should be encouraged. The strong recommendation to use aspirin in patients with a history of cardiovascular events still stands,” she said.

Dr. Gregg C. Fonarow, professor of medicine and director of the Ahmanson-UCLA Cardiomyopathy Center at the University of California, Los Angeles, agreed that aspirin has a place in diabetes care.

“Low-dose aspirin is reasonable for patients with diabetes at higher cardiovascular risk, optional for those at intermediate risk, and generally not recommended in those patients at low cardiovascular risk,” he said.

Fonarow noted that even with these more limited recommendations, “there are many patients with diabetes who are high risk for cardiovascular events who are not receiving aspirin and other cardiovascular protective medications, such as statins, who could benefit from doing so, and who should consult with their physician.”

Another expert, Dr. Joel Zonszein, from the Clinical Diabetes Center, Montefiore Medical Center in New York City, said there’s still a need for much stronger data on the issue.

For now, Zonszein recommends giving patients at risk 325 milligrams of aspirin, “even though we have no [good] data,” he said. “For patients who may have more of a bleeding problem, I give them the baby aspirin, but this is very biased, because we don’t have good data.”

The statement is being published in three journals, Circulation, the Journal of the American College of Cardiology and Diabetes Care.

Tylenol Recall: Health Risks Were ‘Remote’

Thursday, May 27th, 2010

The recall of children’s Tylenol products and other Johnson & Johnson medicines were precautionary measures taken against “remote” health risks, a company executive told lawmakers Thursday.

Drugmaker McNeil Consumer Healthcare, a division of Johnson & Johnson, has recalled products four times in seven months, including a widespread recall of children’s non-prescription drugs on May 1.

That recall took place because some of the products could contain “tiny metal particles,” said Colleen Goggins, the worldwide chairman of Johnson & Johnson.

Johnson & Johnson has suspended production at McNeil’s Fort Washington, Penn., plant that manufactured the children’s products. Other recalls were for adult-strength Tylenol, Motrin and Benadryl products.

“The recall was not undertaken on the basis of adverse medical events,” Goggins said in her testimony before the House Committee on Oversight and Government Reform.

However, CNNMoney has confirmed that the Food and Drug Administration is investigating reports of at least 775 serious side effects from drugs recalled by McNeil.

Johnson and Johnson chief executive William Weldon was invited to appear at Thursday’s hearing, but he declined due to health reasons. A panel of FDA officials are also in attendance.

‘Tiny particles’ and excess ingredients: In her testimony Thursday, Goggins said the “tiny particles” that caused the May 1 recall were “inert, small and sparse” and did not pose a risk of creating internal injuries.

Goggins also testified that McNeil “rejected” any products found to contain excess acetaminophen, which was another concern cited in the recall of its children’s products.

She added that McNeil’s medical experts confirmed that ingestion of even the “highest identified level of excess acetaminophen would not present a medical concern.”

Bacteria ‘not identified’ in any products: Earlier this month, the agency confirmed a bacteria found at the Fort Washington plant was Burkholderia cepacia, which is often resistant to common antibiotics.

“No raw materials that tested positive for objectionable bacteria were ever used in the manufacture of McNeil’s pediatric products,” Goggins said Thursday.

McNeil tested its final products for bacteria, Goggins said, and the company “has not identified any products placed on the market that contained objectionable bacteria.”

On Tuesday, the company outlined steps to remedy the quality and safety lapses at its manufacturing facilities.

Eyeglass Change Might Keep Elderly From Falling

Thursday, May 27th, 2010

Older people might avoid falls if they take off their bifocal or multifocal eyeglasses while taking part in outdoor activities and rely on single-vision lenses instead, a new study suggests.

As people age, they often develop difficulty seeing things at close range, even if they already wear glasses to see at a distance. Instead of using multiple pairs of eyeglasses, they often turn to multifocal lenses — bifocals, trifocals and progressive lenses.

But multifocal eyeglasses can affect balance and increase the risk of falls, research suggests.

For their study, published online May 25 in the BMJ, Stephen Lord, senior principal research fellow at Prince of Wales Medical Research Institute in New South Wales, Australia, and colleagues recruited 606 people over the age of 65 who were at risk of falling and who used multifocal lenses when walking outdoors.

About half of the participants were prescribed a pair of single-lens distance glasses to use when outdoors and in unfamiliar places.

Over 13 months of follow-up, all falls among those who used the single-lens distance glasses fell by 8 percent compared to the control group. Among those who regularly spent time outdoors, falls decreased by about 40 percent. But outside falls increased among those who rarely went outdoors, suggesting that the single-lens glasses aren’t a good alternative for those people.

Medical Apps May Be Risky, Doctors Warn

Tuesday, May 25th, 2010

Wealth and power are no longer conditions of having doctors in your back pocket. These days, all it takes is a smartphone.

There are now more than 2,000 mobile health applications available for download, allowing patients and doctors alike to monitor medications, manage disease, facilitate remote monitoring, and even track labour contractions, all using only a phone. But even as medical professionals praise certain apps for reducing pressure on the health-care system, concerns remain about the absence of regulation and potential for misuse.

“Anybody and their dog can make a medical app, so it’s really important to research the companies behind these things,” says Candice Volney, a nurse from Edmonton. “Some of the diagnoses that come up when people enter their symptoms can be scary, and very deceiving.”

Dr. Turi McNamee, an associate professor at the University of South Dakota’s Sanford School of Medicine, says she relies so heavily on medical apps that she’d feel naked practicing without them.

“I can look up doses of medications, costs, alternative medications for a variety of conditions, and can perform a number of medical calculations without leaving the patient’s bedside,” says McNamee.

“The downside . . . is that they’re full of disclaimers with regards to their accuracy. In theory, if I give a patient the wrong dosage of a medication based on information obtained from an app, the maker of the app would seem to bear no liability whatsoever.”

Scientific American reports that the Food and Drug Administration is weighting regulatory options, though a spokesperson for the U.S. agency would say only that their role in this regard is evolving.

Laypeople who use medical apps face less dramatic risks but nonetheless leave themselves open to anxiety and misdiagnosis – not unlike what occurs when people seek health information on the Internet, which 70 per cent of online Canadians, age 16 and older, have done.

In entering such symptoms as foot pain and cramping into a free WebMD app, for example, the phone-based program returns such possibilities as fibromyalgia, multiple sclerosis, peripheral neuropathy, Lyme disease and anemia.

The University of Regina’s Kristi Wright, citing data from the Canadian Psychological Association, notes that up to 30 per cent of the population experiences intermittent or mild health-related fears, shown to increase reassurance-seeking about symptoms from friends, family, physicians and, more recently, mobile medical apps.

“Access to health information at the touch of a finger represents a technological advance leading to efficient health-care service provision for some,” says Wright, an assistant professor of psychology. “(But) for others, it may serve as a catalyst for continued disability and dysfunction.”

One thing is certain: with eight in 10 doctors expected to have smartphones by the end of this year, the issue isn’t going away.

Dr. Antonia Arnaert, an expert on e-health technologies, says people simply need to be careful about the types of mobile tools they use. In her own research, for example, she recommends patients rely only on the apps that she and her team have vetted.

At present, Arnaert uses medical apps – with the mobile devices provided to patients before they leave the hospital – to help manage people’s diabetes, hypertension and other chronic conditions, as well as provide support for palliative and oncology patients and post-operative care. By having nurses monitor symptoms and conditions remotely, she says hospital beds are freed up and emergency rooms are less crowded.

“It gives patients a kind of control over their disease, and helps them take better care of themselves at home,” says Arnaert, an associate professor at McGill University’s School of Nursing. “It’s developing into a whole new way of health-care delivery.”

As Autism Web Sites Boom, Experts Urge Caution

Tuesday, May 25th, 2010

When Connie Anderson’s son was diagnosed with autism a decade ago, she scoured the Internet looking for treatments.

“I tried all sorts of things I now consider bananas,” said Anderson, now community scientific liaison at Kennedy Krieger Institute’s Interactive Autism Network. “At the time it didn’t feel like nonsense. It was hope. People will try all sorts of things to help their child, sometimes even against their better judgment.”

Since Anderson’s son was diagnosed, the number of Web sites devoted to autism and autism treatments has multiplied. While a 1999 study counted about 100,000 autism Web sites, entering the term “autism” into the three major search engines today yields more than 17.4 million results, according to new research.

So how can parents know how to weed out fact from fiction when faced with so much information? It’s not easy, experts say, but there are some steps parents can take to determine if the information they are getting is from a reputable source.

In a study presented recently at the International Meeting for Autism Research, experts analyzed about 160 of the most visited autism sites to determine how often they met measures of quality and accountability, including whether or not the site was selling something; if citations about research supposedly showing the efficacy of a treatment included author identification and references; if the information was current; and if the site asked visitors for personal information (a red flag).

Most sites did not meet all of the criteria for quality, said lead study author Brian Reichow, a post-doctoral associate at Yale University Child Study Center. And about 17 percent of the sites offered or sold treatments that had little or no scientific support.

“The Internet can provide parents with a lot of useful and helpful information, but there is a lot of misinformation online as well,” Reichow said. “When using it to gain online health information, parents need to be cautious.”

The desire to help their children and the lack of mainstream medical treatments for autism drives parents to seek alternatives, according to Dr. Paul Law, director of Kennedy Krieger Institute’s Interactive Autism Network.

“You don’t see lots of ideas for how to treat ear infections, because the treatment for that is well established,” Law said. In contrast, “there are very few autism-based treatments that the field agrees on, so we don’t have complete answers for those who are suffering from autism,” he said. “That naturally triggers families to seek answers.”

For most of what’s being peddled online, there’s little scientific evidence it works, Law said. His organization has documented some 500 treatments for autism, ranging from diets and vitamins to hyperbaric oxygen therapy.

Anderson cautioned parents to be especially wary of testimonials, no matter how powerful they may seem. For every success story — or a person believing or claiming theirs is a success story — there could be many more failures. “There could be 10 people who have a good experience, and 1,000 who had a bad experience,” Anderson noted.

Experts offered these tips for assessing autism-related information on the Internet:

  • Don’t use the Internet as your sole source of info. Seek support from doctors, physicians, teachers and other professionals.
  • Pay attention to the domain names. In the study, “.com” sites were most likely to be selling unfounded “miracle cures.” Sites ending in “.edu” or “.gov” tend to have oversight committees or quality standards. Government-sponsored “gateway” domains, such as the U.S. National Institutes of Health’s MedlinePlus or the U.S. Department of Health and Human Service’s healthfinder.gov, which each offer a collection of links to other sites, are good places to start because the links have been approved by experts, Reichow said.
  • Look for quality seals such as HONcode (Health on the Net Foundation), a non-profit, non-governmental organization that has developed standards for health information on the Internet.
  • Take testimonials for what they’re worth. The placebo effect can be powerful in autism treatments, and only randomized, controlled experiments are considered the gold standard of proof.
  • Some autism sites will offer scientific data to back up their claims. That information is less reliable if it is generated by the company or the company’s researchers, who may have a conflict of interest or profit motive, Anderson said.

U.K. Bans Doctor Who Linked Autism to Vaccine

Monday, May 24th, 2010

A U.K. medical regulator revoked the license of the doctor who first suggested a link between vaccines and autism and spurred a long-running, heated debate over the safety of vaccines.

Ending a nearly three-year hearing, Britain’s General Medical Council found Andrew Wakefield guilty of “serious professional misconduct” in the way he carried out his research in the late 1990s. The council struck his name from the U.K.’s medical register.

The same body in January concluded that Dr. Wakefield’s research was flawed, saying that he had presented his work in an “irresponsible and dishonest” way and shown “callous disregard” for the children in his study.

Shortly after that January ruling, the British medical journal that first published Dr. Wakefield’s study, the Lancet, retracted it. His central claim—that there could be a link between autism and the measles, mumps and rubella vaccine—has largely been discredited.

Dr. Wakefield couldn’t immediately be reached to comment Monday. In an interview with the British Broadcasting Corp. on Monday, he said he would appeal the GMC’s decision. “Efforts to discredit and silence me through the GMC process have provided a screen to shield the government from exposure on the MMR vaccine scandal,” Dr. Wakefield said, according to the BBC.

Dr. Wakefield’s 1998 study of 12 children triggered worry among parents world-wide that the MMR vaccine caused autism. Many decided not to immunize their children, leading to outbreaks of measles in some Western countries. As many as 2.1% of children in the U.S. weren’t immunized with the MMR vaccine in 2000, up from 0.77% in 1995, according to a 2008 study published in Pediatrics.

A 2004 statistical review of existing epidemiological studies by the Institute of Medicine, a respected nonprofit organization in the U.S., concluded that there was no causal link between the MMR vaccine and autism. Some autism activist groups, however, continue to advocate against vaccinations for children, despite the lack of scientific evidence for such a link.

In an eight-page decision released Monday, the GMC found Dr. Wakefield guilty of numerous cases of misconduct in his research, including: taking blood samples from children during a birthday party without approval from the necessary ethics committee and paying them £5 ($7.24) as a reward; improperly managing and accounting for funds he received to carry out his research; treating the children in his research unethically by causing them to undergo procedures such as lumbar punctures that weren’t clinically necessary; and failing to disclose conflicts of interest to the Lancet, including that he received research funding from a lawyer representing parents who believed the MMR shot had harmed their children.

In the 1998 paper, Dr. Wakefield and his colleagues described 12 “previously normal” children who had developed gastrointestinal problems and developmental disorders including autism. The paper concluded that “in most cases, onset of symptoms was after measles, mumps, and rubella immunization. Further investigations are needed to examine this syndrome and its possible relation to this vaccine.”

Health: Keeping Fit as We Age

Monday, May 24th, 2010

According to one estimate, there are more people in the world today over the age of 65, than the total of all those who previously lived to this age!  And in the United States, the over-85 age group is the fastest growing segment of the population.  Experts in the field of gerontology say that the primary issue among older adults is that of quality of life. With the greater-than-ever life expectancies, just how well will this group function?  Will they spend these years dealing with an assortment of health problems, ailments and chronic diseases, or will they live productive and enjoyable lives?

The effects of time impact all of our basics systems.  The cardiovascular system sees changes a steady decline in the sympathetic nerve system activity to the heart, resulting in a lower maximal heart rate and reduced strength in each contraction.  There is a decrease in the elasticity of the major blood vessels, which can cause a rise in blood pressure. The cardiac muscle itself can become stiff, which leads to a reduction in the pumping efficiency of the heart. Our lungs don’t work as well either.  Because of the various physiological changes in the lungs, especially the integrity of the alveoli, there is an increase in the energy cost of breathing.

The musculoskelatal system also undergoes numerous changes with aging.  Muscle mass declines with age, and does strength.  This leads to loss of mobility, balance problems, walking problems and increased likelihood of falls.  Osteoporosis can result from aging, as our bone mineral content decreases.

A significant portion of what is described above results from non-use and a general lack of physical activity.  The question is: Can exercise slow up the aging process?  The answer is most definitely YES!  Research has shown that you can decrease your cardio- respiratory deterioration by as much as 50% with effective and consistent aerobic training.  This means that a 60-year-old person who is active can be as aerobically fit as a 40-year-old.  Also, seniors who remain active don’t get the typical rise in blood pressure with aging that sedentary people get.  And not only can you slow muscle deterioration; you can actually build muscle mass and increase your flexibility with a good stretching program.

Every minute of everyday, we get older.  There is no magic fountain of youth. However, staying active and setting aside time for formal exercise can make the golden years pleasurable and enjoyable ones. Keeping fit even as we age is another way to “add hours to your day, days to your year and years to your life.”

Health: It’s Easier than You Think!

Monday, May 17th, 2010

Making Exercise Part of Your Daily Routine

In the high tech, time-saving world of Internet, computers, cell phones, email and faxes – all of which are supposed to simplify our lives and give us MORE free time, we still can’t find the time to take care of ourselves – or so we think.  Perhaps we don’t value ourselves as much as we value our hardware or software.  Sometimes we may think that we don’t have the time to exercise. But in fact, we do.

Prioritize and organize. These are two key words to learn and put into practice.  Use your time efficiently, and you will be surprised at what you can accomplish before the end of the day.  Although some people like to do a complete 1-hour exercise session 4 or 5 times a week, shorter, more frequent sessions are also an option. The most important thing to remember is that something is much better than nothing.  Keeping these points in mind, let’s see how, given your busy schedule, you can still incorporate the proper amount of exercise into your day.

First, in the morning, wake up just 5 minutes earlier.  After you have a few glasses of water, do a 2-minute simple calisthenics routine.  Then, spend another 4-5 minutes doing some easy stretching.  Now, if you are going to work, walk two bus stops away and get off two bus stops before your destination.  If you drive, park far enough away so that you get an 8-10 minute walk to work.  Try not to use the elevator to get to your office.  Use the stairs. (This applies to everyone, all the time.) At your lunch break, take 15 minutes to eat and go outside with friends and walk for 15-20 minutes.  You’ll feel refreshed when you come back. And an added benefit… You’ll most likely find that it will improve your ability to work efficiently.  

Later in your working day, take a 5-minute break.  Drink a glass of water, and then do 15 pushups against the wall of your office.  Then, try squatting and standing up again 8-12 times.  While sitting at your desk, do seated çrunches as follows:

Sit up tall with one hand behind your head and the other one holding onto the edge of your chair’s seat. Pull your abdominal muscles inward. Slowly curl down and forward just a few inches. As you do so, pull your abs in even tighter. Hold a moment and then slowly uncurl to a very tall position. This move strengthens your abdominal muscles.  Try 10 or so.  

During the course of the day, you can try some of these basic desk stretches:

Stretch your shoulders and neck by gently rolling your shoulders clockwise and counter clockwise 10 times in each direction.

Stretch your lower back by draping forward over your lap.

To stretch the back of your leg, extend your leg, lean over in your chair and reach your arms towards your feet. You can increase the effectiveness of this stretch by lifting your toe up in the air. (Repeat on both sides.)

At the end of the workday, when you’re on the way home, make sure you get in another 5-10 minutes of brisk walking.  Between all those staircases and walking, you’ve probably accumulated about 30 minutes of aerobic exercise for the day. As you can see, every little bit helps. And beyond these tips, it helps to approach every day and every situation as a workout waiting to happen. If you have the time, or can try hard to make the time, there are certainly better and more beneficial ways to work out, but on the days that you just can’t manage more time, just fit it in wherever you can. With a little initiative, you can  “add hours to your day, days to your year, and years to your life.”

‘No Link’ Between Cell Phones & Brain Tumors

Monday, May 17th, 2010

A long-awaited international study has found no evidence of increased risk of brain tumors associated with mobile phones, but said the findings were not definitive and called for more research.

“The possible effects of long-term heavy use of mobile phones require further investigation,” the study said.

Critics of the decade-long Interphone study, published Tuesday in the International Journal of Epidemiology, argue that the research methodology was flawed and that the study lacks a definitive conclusion.

“I’m not telling people to stop using the phone. I’m saying that I can’t tell you if cell phones are dangerous, but I can tell you that I’m not sure that they are safe,” said Dr. Devra Davis, professor of Preventive Medicine at Mount Sinai Medical center in New York.

She particularly cited the study’s exclusion of children and young adults, the mobile phone’s increased popularity since the study period, the fact that only two types of brain tumors were studied and Interphone’s definition of a “regular” user is not consistent with cell phone use today. She also noted that the study’s control groups were unorthodox.

“Their comparison isn’t between people who used cell phones and didn’t. It was between people who used their phone less than once a week, and more than once a week, all on self-reflection memory of their mobile use, the day after they’ve had a brain operation.”

The study defined regular cell phone user as ever having one phone call a week for at least six months. The results of the study were based on patients’ average talk time ranging from 120 minutes to 150 minutes a month; most users today far exceed that. It’s “what some people in the U.S. would use in a week in 2010,” Davis said.

The study was conducted at 16 locations in 13 countries, not including the United States. In hospital interviews, brain tumor patients were asked to answer a series of questions based on memory about their mobile phone use habits prior to being diagnosed. They were asked to reflect on how many hours they talked on their phone a month, how long they had been using their cell phone, if they remembered how many phone calls they made a month and to what side of the head they typically held the phone.

The study focused on two types of tumors – glioma and meningioma.

The study was funded in part by the cell phone industry. Several of the researchers analyzing the data acknowledged that they received money from the mobile phone industry.

Helmets Make Riding Safer

Sunday, May 16th, 2010

As summer approaches and many Americans start to dust off their bikes, blades and assorted motorized vehicles, the nation’s emergency department doctors are trying to direct public attention toward the importance of wearing safety helmets to prevent serious brain injury.

“People are riding bicycles, motorcycles and ATVs [all-terrain vehicles] more often at this time of year,” Dr. Angela Gardner, president of the American College of Emergency Physicians (ACEP), said in a news release. She stressed that people need to get in the habit of wearing a certified safety helmet, because it only takes one tragic crash to end a life or cause serious life-altering brain injuries.

Citing National Highway Transportation Safety Administration (NHTSA) statistics, the ACEP experts note that every year more than 300,000 children are rushed to the emergency department as a result of injuries sustained while riding a bike. Wearing a helmet that meets Consumer Product Safety Commission standards could reduce this figure by more than two-thirds, the organization suggests.

But children aren’t the only ones who need to wear helmets. In fact, older riders account for 75 percent of bicycle injury deaths, the ACEP noted. Among bicyclists of all ages, 540,000 seek emergency care each year as a result of an accident, and 67,000 of these patients suffer head injuries. About 40 percent experience head trauma so serious that hospitalization is required.

A properly fitted helmet can prevent brain injury 90 percent of the time, according to the NHTSA, and if all bicyclists between the ages of 4 and 15 wore a helmet, between 39,000 and 45,000 head injuries could be prevented each year.

With May designated as motorcycle safety month, the ACEP is also highlighting the benefits of helmet use among motorcyclists.

“Helmet use is the single most important factor in people surviving motorcycle crashes,” Gardner stated in the news release. “They reduce the risk of head, brain and facial injury among motorcyclists of all ages and crash severities.”

The ACEP cites NHTSA numbers indicating that in 2008, helmets saved the lives of more than 1,800 motorcyclists — a figure that could have risen by another 800 lives saved if all motorcyclists wore helmets. Not wearing a helmet increases the risk of dying from a motorcycle-riding head injury by about 40 percent, experts say.

Gardner and colleagues encourage people of all ages to wear helmets every time they go for a ride on a bicycle or motorcycle, but also when roller skating, rollerblading, skateboarding and/or engaging in a high-contact sport.

Health Claims on Foods May Not Be Well-Grounded

Wednesday, May 12th, 2010

U.S. consumers are being misled by the health claims made on the packaging of foods and supplements, according to a new report by the Institute of Medicine, because those claims do not undergo the same scientific rigor required for such claims on medications.

A box of cereal that proclaims the breakfast food will lower your cholesterol, for instance, has not had to pass the same government standards as the claims on the packaging of a cholesterol-lowering drug.

“There is evidence that things get on the market because the standard is lower,” said Dr. John Ball, executive vice president of the American Society for Clinical Pathology and chairman of the committee that wrote the report, which was released Wednesday.

“Consumers probably assume that if the FDA said it’s OK, it’s OK,” Ball said. “But in fact, the OK for drugs is a much higher OK than the OK for food supplements.”

Faced with a barrage of health claims for foods, the FDA asked the committee to develop a way in which those claims could be better evaluated, Ball said.

Most health claims on food packaging, he said, are based on the supposed beneficial effects on biomarkers, which are a measure of a biological process, such as blood pressure or cholesterol. A cereal might be sold to consumers as being good for the heart when, in fact, that clinical outcome has not been tested.

Dr. Robert H. Sprinkle, an associate professor in the School of Public Policy at the University of Maryland, described food marketers’ use of biomarkers in making health claims as “misappropriated” because “they may not mean much in the context in which they’re cited.”

For example, Sprinkle said, “our cereal does XYZ, and we want to say so … and some experts think that’s favorable, so we want to have you credit [it] with having that effect — even though we don’t really know if that effect is creditable here.”

The committee’s job was to come up with a framework that the FDA could use to judge the appropriateness and validity of such claims. As Ball wrote in the report, “consumers wish to choose healthier diets, the food industry has an interest to market its products as healthy, and the FDA needs to minimize risks to the food supply and to inform consumers appropriately.”

The first thing the FDA needs to do when faced with a health claim for a food product, Ball said, is to determine whether the particular biomarker that’s being cited has anything to do with the disease about which the claim is being made. The next step would be to determine whether the product actually affects that biomarker.

If a manufacturer wants to say that its product is good for the heart because it lowers blood pressure, Ball explained, the first question would be whether blood pressure is a valid biomarker (which it is) and then whether it’s a associated with the disease that the product claims to treat (which in this case it is).

After that, the FDA would have to determine if the claim is justifiable, he said.

“Are they making the claim that if you eat our food you’ll prevent death?” Ball said. “That would be a different claim than if you eat our food there is a potential for reducing your blood pressure.”

That can consume consumers, he said. People who look at just the front of the package see only the claim, but important data is in the nutritional panel on the box, he said.

Another problem, according to Ball, has been that for each of the areas FDA regulates — food, food supplements, drugs and medical devices — the scientific standard has been different. Food manufactures can make a claim for a health effect or for a decrease in risk as long as there is any degree of evidence, which is not the same standard required for a drug, he said.

“For food supplements, the standard is even lower,” Ball said. “There is a presumption in favor of the supplement, and the FDA has to show that it’s got a negative effect in order to be able to do anything about it.”

“We are saying, ‘You ought to have the same basic scientific standard for all the products,’ ” Ball said of the committee’s report.

In addition, the FDA needs to do a better job tracking products once they are on the market, he said. “One of the things we did find [was that] even in post-marketing surveillance, where companies agreed to come forward with information, only about 10 percent of those agreements have been fully followed up,” he said.

The bottom line for Ball is that the FDA needs more authority to regulate health claims being made — a change that would require Congress to change the laws under which the agency operates.

As Sprinkle said: “A lot of what you see driving this report is revealed where the IOM says that Congress should give the FDA more authority and more money. But that recommendation is sure to be opposed vigorously, but, of course, quietly.”

“So is this all about biomarkers?” he asked. “Well, yes and no.”

Fluctuating Blood Pressure Ups Stroke Risk

Tuesday, May 11th, 2010

People who have fluctuating blood pressure in addition to high blood pressure are at increased risk for cerebrovascular disease, new research shows.

Cerebrovascular disease, which includes stroke and other disorders that affect the brain’s blood vessels, is associated with disability and a decline in memory and reasoning powers in older adults.

The new study included 686 dementia-free older adults who had their blood pressure measured during three study visits at 24-month intervals. The participants, who also underwent MRI to check for cerebrovascular disease, were divided into four groups depending on whether they had high or low blood pressure, and whether they had high or low blood pressure fluctuations between visits.

People with the lowest fluctuations had changes of about 5.5 percent (among those with low blood pressure) and 5.2 percent (among those with high blood pressure), while those with the highest fluctuations had changes of 14.2 percent, the study authors noted.

High blood pressure and fluctuations in blood pressure were both independently associated with increased risk of cerebrovascular disease. But people with both factors were at even greater risk, according to study author Adam M. Brickman, of the Taub Institute at Columbia University in New York City, and colleagues.

The researchers also found that participants with the highest blood pressure and fluctuation levels were most likely to be prescribed blood pressure-lowering drugs. This suggests that failure to adhere to treatment may be a source of blood pressure fluctuation.

“Cerebrovascular disease is associated with a constellation of conditions that lead to disability, including cognitive impairment, mood and movement disorders,” the researchers concluded. The new findings, they stated, suggest that managing blood pressure fluctuations, even in older adults with normal blood pressure, “may be beneficial in reducing the risk of cerebrovascular disease and in maximizing healthy cognitive aging.”

The study is published in the May issue of the journal Archives of Neurology.

Health: The Real Deal On Fats

Monday, May 10th, 2010

The Good, the Bad and the Ugly:

Over the past 40 years, the “public enemy number one” of food has been fat. We spend billions of dollars per year on low-fat foods, fake-fat chips, pills that block the absorption of fat into the digestive system, and all types of specials diets and cookbooks. And in the past 30 years, we have reduced the amount of fat in our diet by 34%, on average. The problem is, we aren’t any thinner or healthier for all this effort. One of the reasons for this is that some fats are actually good for you, but we are not including them in our diet.

Let’s take a look at which fats need to remain minimal in your diet and which should be consumed more frequently. There are four main categories of fatty acids: saturated, monounsaturated, polyunsaturated, and trans fatty acids. Fats play an important role with regard to nutrition, and perform critical functions in the body, including insulation, cell structure, nerve transmission, vitamin absorption and hormone production.

Saturated Fats  These are the fats that harden at room temperature. Approximately 2 dozen saturated fats exist in nature. They are found in large proportions in meat and animal fat, dairy products and palm and coconut oil. These are the fats that affect your cholesterol and lead to atherosclerosis – the process of clogging of the arteries. Butter and dairy products are the worse of the bunch, followed by animal fats, and then by chocolate and cocoa butter.

Trans Fats  These fats were created by man by solidifying a polyunsaturated fat through heating and hydrogen. They help manufacturers increase the shelf life of foods. Trans fats are found in margarine and Crisco, and in the hydrogenated vegetable oil found in food products. BEWARE! These fats are hazardous to your health and even if a product claims to be free of trans fats, it may still contain some. Check the ingredients for hydrogenated or partially hydrogenated oils. If you find that word, then it contains trans fats, no matter what the label says.

Monounsaturated Fats  These fats are liquid at room temperature and are essential in your diet. Olive oil, canola oil, peanut oil, as well at avocados and nuts are excellent sources of this fat.

Polyunsaturated Fats  These fats are also liquid at room temperature and come in two varieties: N-6 and N-3. Also important in your diet, these fats are obtained from plant oils such as corn and soybean, or seeds, whole grains, and fatty fish such as salmon and tuna. The balance between the N-6 and N-3 is very important. N-6 is more common, so look for omega-3 in order to keep things balanced.

The benefits of consuming both monounsaturated and polyunsaturated fats include lowering your LDL (bad cholesterol) and raising your HDL (good cholesterol). They also prevent an increase in triglycerides that can occur in a high carbohydrate diet, reduce the development of irregular heart beats, and reduce the incidents of blood clots. Trans fats, found almost everywhere, need to be avoided at almost all costs. They have been found to be very aggressive in starting or sustaining the process that leads to clogged arteries. Saturated fats need to be limited to no more than 10%-12% of your dietary intake.

So get to know your fats and learn to make healthy choices. It’s definitely a great way to “…add hours to your day, days to your year and years to your life.”
