Garlic and other foods in the allium family (onions, leeks, chives, shallots, and scallions) work to stimulate the production of glutathione, an antioxidant that is especially important in the liver, where it helps remove hormone-disrupting chemicals.
Alliums also lower total cholesterol while raising the level of HDL cholesterol (the “good” kind). Preliminary research suggests that garlic may boost testosterone, giving you more energy, while onions have anthocyanins, effective free-radical destroyers that might also help combat obesity and diabetes. Crushing, chopping, or chewing garlic helps release enzymes that trigger many of its beneficial actions.
How to fit garlic into your diet:
Pair garlic with olive oil to release even more disease-fighting compounds. Let chopped garlic stand for ten minutes before cooking; this will allow the enzymes to be activated. Add garlic to homemade salad dressings, marinades, soups and sauteed vegetables for a flavor kick.
