My gene test indicates I lack the required detoxification mechanisms to remove free radicals formed by toxic waste (xenobiotics). Overaccumulation of xenobiotics can lead to a range of health problems. A diet high in cruciferous vegetables (eg broccoli and cauliflower), allium vegetable, citrus peel and the spice tumeric will aid in detoxification, which will improve exercise tolerance and reduce fatigue.
From an interview with Jonny Bowden at T-nation:
Q: You wrote in your 150 Healthiest Foods on Earth book that turmeric, the spice, deserved to have a whole book written on it. What's so great about this stuff, besides the fact that it makes Indian food taste good?
A: The active ingredient in turmeric is curcumin, a member of a class of plant chemicals called curcuminoids. Curcumin has anti-cancer properties. Even the very conservative American Cancer Society says on its website that curcumin has "demonstrated some anti-cancer effects."
Several types of cancer cells are inhibited by curcumin in the lab, and it's slowed the spread of cancer in some animal studies. It's also a powerful antioxidant and highly anti-inflammatory as well, and since inflammation is a component of virtually every degenerative disease on the planet, that's a very powerful résumé.
And if that weren't enough, curcumin (or turmeric) is one of the most liver-friendly compounds on the planet, which is why you almost always see curcumin in liver-detox supplements.
