5. Sweet potatoes: 2g of soluble fiber per serving

Sweet potatoes are high in potassium, beta-carotene, B vitamins, and fiber. Just one medium sweet potato contains more than 400% of the daily requirement of vitamin A.
Besides, the average potato contains about 4 grams of dietary fiber. And almost half of it is soluble.
