Wheat berries, like most whole grains, are an excellent source of dietary fiber - which promotes digestive health; helps lower blood cholesterol and blood sugar levels; aids in weight management and encourages regular bowel movements. The Harvard School of Public Health reports that whole grains, such as wheat berries, contain plant estrogens or phytoestrogens that may reduce your risk of developing certain types of cancers - particularly in conjunction with minerals found in whole wheat - such as magnesium, selenium, copper, and manganese.
