SNACK ON POPCORN
Who knew? Corn, the tiny kernel that most of the world calls maize, is a whole grain! Research shows that those people who snack on popcorn eat whopping 250 percent more whole grains and 22 percent more fiber compared to non-popcorn eaters. Just be sure to avoid the unhealthy popcorn additives: salt and butter—which ruin a perfectly heart-healthy food.
