Soluble fiber helps you feel full and supports regular bowel movements. Adding some of these 20 high soluble fiber foods to your diet may help you manage your digestive health.
Dietary fiber is the carbohydrate in plants that your body cannot digest.
Both soluble and insoluble fiber help bulk up your stools and can be used as a food source for good bacteria in your large intestine.
Soluble fiber draws water into your gut, which softens your stools and supports regular bowel movements.
It not only helps you feel fuller and reduces constipation but may also lower your cholesterol and blood sugar levels (
Here are 20 healthy foods that are high in soluble fiber.
Black beans are not only a great way to give your dishes a meaty texture but also an amazing source of fiber.
Black beans contain pectin, a form of soluble fiber that becomes gummy-like in water. This can delay stomach emptying and make you feel fuller longer, giving your body more time to absorb nutrients (
Black beans are also rich in protein and iron, low in calories, and almost fat-free (4).
Soluble fiber content: 5.4 grams per three-quarter cup (129 grams) of cooked black beans (6).
Lima beans, also known as butter beans, are large, flat, greenish-white beans.
They mainly contain carbs and protein, as well as a little fat.
They’re lower in total dietary fiber than black beans, but their soluble fiber content is almost identical. Lima beans also contain the soluble fiber pectin, which is associated with reduced blood sugar spikes after meals (
Raw lima beans are toxic when raw and should be soaked and boiled before you eat them (
Soluble fiber content: 5.3 grams per three-quarter cup (128 grams) of lima beans (6).
