A healthier diet, if you have a baddish one will help a lot of things healthwise, but what if you don't smoke and have never done so, don't drink much alcohol, don't eat fried foods, or red meat, have never touched coffee, drink very little tea, drink lots of water, little dairy....? I think a lot of these so called diets are just a money making racket, and surely trying out all these diets and supplements will do more harm than good in the long run as it's just messing your systems up more?
Love the discussions though, very interesting.
