It's interesting that you appeal to what "scientists believe" in one breath and in the very next you deride medical science.
Your holistic woo may have worked just fine for your family, but the plural of "anecdote" is not "data." Exercising, eating healthy foods, getting enough sleep, avoiding stress, and taking vitamins is good advice even for healthy individuals. But it's

You needed to take a kid to a doctor over a broken arm. Taz's medical issue is a heritable genetic disorder, not something that he can solve just by cutting out the junk food. People with actual autoimmune disorders and diseases often require
real medication for their entire lives. HIV patients who try your holistic woo will wind up with AIDS; transplant patients will wind up with rejected organs.
