Cigarettes are unhealthy, but so is eating an amalgamation of high fructose corn syrup and hydrogenated fats/oils (frum brands of parve ice cream).
Likewise, Pesach mayonnaise is made with cottonseed oil- this is genetically modified, contains high amounts of Omega 6 fatty acids, and pesticide residues.
Also, the Bissli for Pesah is loaded with MSG, and Pesah potato chips are also fried in cottonseed oil.
Trans fats galore exist in Kinneret parve creamers and whipped topping; partially hydrogenated palm kernel oil in the Kinneret Pesah parve cream have been associated with numerous health issues including cancer, heart disease, immune system dysfunction, sterility, learning disabilities, growth problems and osteoporosis.
I don’t condone smoking, but the fact of the matter is that people are going to smoke and eat foods that aren’t the best for them, despite the Torah’s injunction to care for one’s health.
But I felt that to be consistent, if you condemn Pesah cigarettes for being unhealthy but deemed “mutar” by a hashgaha, what do you do with all the Pesah foods made with trans fat, hydrogenated oils, MSG, etc.?
