Any feedback on why this was downvoted?

There seems to be an overwhelming amount of bad health advice out there, but I've spent years looking for the most effective and rigorous methods to improve my own health, and the links above are the best methods I've been able to find.

It's hard to explain in a short post how good these materials really are but they've radically improved health and quality of life for me, and most of my friends and family who tried them.

Edit: I suspect the signal to noise ratio for "diet advice" is so terrible, everyone needs to assume it's all crap, or else they'd spend too much time evaluating everything they hear.
