In general, the darker the color of the vegetable, the higher the fiber content. Carrots, beets, and broccoli are fiber-rich. Collard greens and Swiss chard have 4 grams of fiber per cup. Artichokes are among the highest-fiber veggies, at 10 grams for a medium-sized one.
A study published in today's Annals of Internal Medicine suggests that something as simple as aiming to eat 30 grams of fiber each day can help you lose weight, lower your blood pressure, and improve your body's response to insulin just as effectively as a more complicated diet.
