According to the latest U.S. Dietary Guidelines, adults and children alike should have from 5 to 13 servings of fruits and veggies a day, each serving at least 1/2 cup. While this is beyond what most people currently consume, it’s not an impossible task. For veggies, simply include them with foods you and your family already like. In general, you need to eat a wide variety of vegetables, including plenty of the bright- and deep-colored ones, to get all the vitamins, minerals and fiber that veggies have to offer. With the exception of soy foods, though, the protein in plant foods is incomplete. It lacks one or more of the protein building blocks that your body can’t make.
