Statistics show that of all people who die, more than 95% have eaten pickles.
I beg to differ with your inference. There are many people who buy into the conspiracy theory that the vitamin/supplement industry circulates about scientific medicine, who die of treatable illnesses that they refuse. Yet, the industry is in total denial of this. There are also numerous adverse reactions to these products together with interactions among them that are potentially dangerous, even fatal. These are not studied (there is no financial support for research), so there are never warnings. As for natural vs. synthetic, there may be differences for certain items, but no known difference for others. It is sad that there is so little reliable data about vitamins.
