Food fetisists can be disgusting.

We should not eat many things, not because we are 'leftists' but because real science shows they are unhealthy - poisons. There are 'fast acting' poisons, like arsenic, and slow acting poisons, like refined sugar. You wouldn't eat arsenic on a regular basis. Small amounts won't hurt you, but large amounts will kill you quickly.
This is the same with certain 'foods' in our diet. Avoid refined sugar. Avoid grains. Avoid processed foods. Avoid all soy products, unless fermented. Eat most everything else. Bacon, meats, butter, vegetables. I fry my eggs in bacon fat every day. I fry my French fries in lard.
I am not a 'leftist' but an educated consumer of food.
