Corn
Some of us frown on corn because it’s a stuffy vegetable. Well, it is stuffy because it’s a grain! One cup of corn kernels has 5 grams of protein, 4 grams of fiber – that’s more than 25 percent of the daily recommendation – and energy-producing B-vitamins. You can also eat corn in a wide variety of ways — tortillas, polenta and popcorn are all healthy whole-grain choices.
