In case you snoozed through health class, let's review the importance of whole grains. Unlike refined grains, which have been stripped of the bran and germ (and a host of nutrients in the process), whole grains remain physically and nutritionally intact. They're packed with fiber, iron, and vitamin B and may reduce the risk of heart disease and diabetes. The USDA recommends that most adults consume 6 ounces of grains a day, at least half of which should consist of whole grains. Still, only 5% of Americans get enough whole grains on a daily basis. The bottom line: It's time to get your grain on! Start with these eight strategies for sneaking more into your diet.
