Eating whole foods is essential for optimum nutrition and is a significant anti-aging strategy. Eating whole grains—and foods made from them—is part of this strategy. Whole grains have more nutrients than refined grains. Ancient grains—such as emmer wheat (farro), einkorn, kamut (khorasan wheat), spelt, barley, rye, triticale, semolina, durum, and buckwheat—are far more nutrient dense than modern American high-yield wheat.
