Antioxidant News and Research

RSS

Antioxidants are substances that protect cells from the damage caused by free radicals (unstable molecules made by the process of oxidation during normal metabolism). Free radicals may play a part in cancer, heart disease, stroke, and other diseases of aging. Antioxidants include beta-carotene, lycopene, vitamins A, C, and E, and other natural and manufactured substances.

Novel method quantifies the total polysulfide content in fresh vegetables

Sulfur-rich foods, like onions and garlic, have long been recognized to have health-promoting properties. It has been difficult to investigate how food containing sulfur compounds enhances health because the levels—and types—of reactive polysulfides found in various vegetables have not been adequately assessed.
