I have eaten a mostly non gmo and organic food diet. It made such a huge difference diet for roughly 10 years and it works wonders. Sugars,caffeine and yes booze rob your system of water and drain your natural energy!
If it has not been talked about your personal hygiene products are also very toxic unless you know what to avoid. toothpaste,shampoo etc. natural news is a great site to find good info. when it comes to things to avoid in general as well as a ton of healthy/homeopathic things.
