Truly excellent post. One thing I've learned over the past few years is that when you eat enough of a food (especially processed foods or something you're allergic to), your body will develop what are called "masking antibodies." These antibodies do their best to combat the negative effects of the food and protect your body from the damage, which sometimes masks the symptoms. So when people argue, "Well it doesn't do anything to me! I don't notice anything wrong," unfortunately there's more happening behind the scenes than they realize.

P.s.I love how you call bad ingredients "poison." I thought I was the only one! Sometimes I'll say a restaurant or family member "poisoned me" and people definitely think I'm being dramatic, but it's the truth!
