But the issues of ownership is rarely an all-or-nothing proposition. A major system development effort often involves the integration of custom-developed software with existing programs, either proprietary to the developer, the client or a third party.
Editor's Note: USDA scientists analyzed antioxidant levels in more than 100 different foods, including fruits and vegetables. Each food was measured for antioxidant concentration as well as antioxidant capacity per serving size.Cranberries, blueberries, and blackberries ranked highest among the fruits studied.Beans, artichokes, and Russet potatoes were tops among the vegetables. Pecans, walnuts, and hazelnuts ranked highest in the nut category.SDA chemist Ronald L. Prior says the total antioxidant capacity of the foods does not necessarily reflect their health benefit. Benefits depend on how the food's antioxidants are absorbed and utilized in the body.
Examples of antioxidants include vitamins C and E, selenium, and carotenoids, such as beta-carotene, lycopene, lutein, and zeaxanthin. This fact sheet provides basic information about antioxidants, summarizes what the science says about antioxidants and health, and suggests sources for additional information. The beneficial health effects of a diet high in vegetables and fruits or other antioxidant-rich foods may actually be caused by other substances present in the same foods, other dietary factors, or other lifestyle choices rather than antioxidants.
