I understand that. But my body doesn’t care who prepared the food. If a big corp prepares the food the same way I prepare it at home (or vice versa), then this advice is useless.
I am sure that he placebo could improve his energy. Also, I’m sure there are ingredients that “big corp” uses that we wouldn’t normally use in the kitchen that could hurt our health. So then instead of saying avoid “processed foods” (which means nothing and everything), name the ingredients and the processes that are bad.
