What's in them: A wide variety of nutrients, thanks to the many colors they come in.
The belly-fat connection: Overweight young people whose diets included "nutrient-rich" vegetables (those that are dark green, orange or yellow) had 17 percent less abdominal fat than study subjects who didn't eat that type of produce, according to a study in the
Journal of The Academy of Nutrition and Dietetics. (Researchers often refer to these vegetables as "nutrient-rich" because their vibrant colors mean they're high in nutrients like carotenoids and chlorophyll.) It's not clear why these deeply hued veggies may contribute to less belly fat (they're also high in fiber, which may play a role), but more reason to eat your vegetables isn't a bad thing.
More ideas of what to eat: Any vegetables with green, orange or yellow coloring should be on your grocery list, like Brussels sprouts, carrots, sweet potatoes and squash.
