Document Summary
A food that provides health bene ts beyond the essential dietary nutrients it contains is called a functional food. Food groups that are rich in sources of antioxidants: grains, veggies, and fruits. Cancer represents abnormal and uncontrollable division of cells that results from mutations in. Oxidative stress describes a situation in which the production of free radicals outpaces the body"s antioxidant defenses. Nutrients reduce oxidative damage to cells and dna by donating electrons to reactive molecules, accepting electrons from reactive molecules, ad serving as cofactors in chemical reactions that neutralize free radicals. Excess calorie intake, eventually leading to obesity, is the main diet-cancer risk factor. Vitamin e is implicated in the prevention of chronic diseases, such as cancer, cataracts, and cardiovascular disease because it can prevent oxidative damage. Free radicals: have an imbalance between protons and electrons, are unstable, and can damage cell membranes.
