Diet Greens Greens are packed with vitamins, minerals, fiber and phytochemicals for disease prevention. They contain:Carotenes. beta carotene, lutein, lycopene, andzeaxanthin. Carotenes are antioxidants that ward off many age-related diseases, and are Vitamin A precursors. Fiber. Most greens provide about 2 to 5 grams of both soluble and insoluble fiber per one cup serving.. Folic acid. This B vitamin works with enzymes that dispose of homocysteine, a harmful blood chemical that irritates artery walls. Phytochemicals. In addition to carotenes, greens also supply an array of other cancer-fighting phytochemicals. These nonvitamin/nonmineral substances found in all plants are believed to help protect leaves from UV sunlight, parasites and other invaders. Phytochemicals work by boosting enzymes that fight cancer cells or cancer-causing agents . Watercress, for example, contains the family of phytochemicals called isothiocyanates that inhibit carcinogens you get from tobacco smoke. To obtain the benefits of several different phytochemicals, a variety of greens should be consumed. Magnesium. This mineral plays a vital role in energy metabolism. Poor magnesium intake may make the heart work harder. Iron. The body absorbs iron poorly from some greens, such as spinach, because these greens also contain a substance called oxalate that binds iron (and calcium) and makes it unavailable for use. Adding acidic foods such as tomatoes or citrus fruits will help your body break the iron down into a more absorbable form. Potassium and Calcium. Greens are decent sources of these minerals.
