Whenever possible, eat raw fruits and vegetables. Vitamin C is very easily oxidized by air. In fact, orange juice and cantaloupe can lose half their Vitamin C content if not stored properly. Wrap tightly in plastic or store juice in a small container. This minimizes their exposure to air.
Tomatoes contain both Vitamin C and betacarotene.
Both are powerful antioxidants. Vitamin E is another powerful antioxidant. You can find it in sunflower seeds, wheat germ and fortified cereals. Whole grain breads and cereals contain magnesium, iron, zinc, B Vitamins and fiber. Good sources of folacin are broccoli, beans, spinach, romaine lettuce, eggs, and oranges.
