Where to Find Them
Phytonutrients are not available in any pill or potionthough researchers hope they will be someday soon, so people can receive their benefits in concentrated form. Until then, there's only one way to get them: through fruits, vegetables, and grains.
The Emerging Superstars
Hundreds of phytonutrients have been identified so far; but as yet, little or nothing is known about many of them. But those that have been studied show tremendous promise as health and healing dynamos. Below are some of the major finds.
Allylic Sulfides
Best sources: onions and garlic; also found in lower concentrations in leeks, shallots, and chives. Released when plants are cut or bruised.
What they do: fight bacterial, viral, and fungal infections; aid circulation; detoxify the liver; may help prevent heart disease by lowering cholesterol and fat levels; lower blood sugar levels; may protect against cancer, particularly stomach cancer, by detoxifying cancer-causing chemicals.
Phenols
Best sources: almost all fruits, vegetables, and grains, as well as green and black teas.
