what are the best sources for living a toxic-free all-natural organic optimal energy die at 100+ lifestyle?

I am trying to get rid of all toxins- pollution, nail polish, cleaning products, processed foods, you name it.
I want to eat only foods from the earth that will give me a clear sharp mind, a calm stress-free spirit, and a body slim, fit, and bouncing with the energy of an olympian.
However, this is new to me/ total beginner in terms of where do i shop, what do i read, what do i watch out for, what dont i buy, what herbs can heal where over the counter meds can not, where are over the counter meds actually necessary, etc.
E.g. I have bad shin splints but want to run minimum 3 times a week and the only way to run w/o screaming pain is taking 2 ibuprofen pills prior to working out- am i just unedcated on alternatives? websites, books, experts I can immerse myself with? the more free the info available the better
thanks in advance!!

If you want it for free, get a library card and check out their health books. I just read “You Don’t Need Meat” and it detailed exactly the problems that arise from a meat-laden diet. The library will have countless other health books as well.

There’s a really interesting and long article here: https://www.purefood2u.com/pdf/article1.pdf It talks about the dangers of preservatives, MSG, artificial sweeteners, etc.
