Your diet advice is great for people who don't have a food intolerance. I'm glad it worked well for you. As someone who has pretty serious - immediate diarrhoea, stomach pain etc - responses to certain foods (dairy, gluten, some alcohol sugars) cooking whole foods from scratch and supplementing with vitamins doesn't cut it. Lots of other people are in the same position. There's a lot of research about why these issues are growing - newer pesticide resistant crops seem one likely avenue - but they're real, and deeply disruptive for the people who have them. Speaking for myself, I grew up in a home where all our meals were cooked from scratch, no fast food or 'candy', and was horrendously sick growing up due to the amount of (whole wheat, locally baked) bread and dairy in my diet. Had ulcers in my early teens, constant stomach upsets, and lots of secondary related issues. Certainly eating poorly makes these issues worse, but I didn't grow up in a food desert, or eating an American diet, and they emerged none the less. And at a time (I'm 44) when there was zero awareness of them in the culture. I was exposed to tonnes of antibiotics as a child - but its hard to deduce cause and effect here. The antibiotics were given because I had frequent gastric distress. Either way, I'm sure my gut bacteria are in a terrible state.
