Fiber is classified as soluble, which dissolves in water, and insoluble, which doesn’t dissolve.
SOLUBLE FIBER. This type of fiber dissolves in water to form a gel-like material. It can help lower blood cholesterol and glucose levels. We can find it in oats, peas, beans, apples, citrus fruits, carrots, and barley.
INSOLUBLE FIBER. This type of fiber promotes the movement of material through your digestive system and increases stool bulk. It can have a positive effect on those who struggle with constipation or irregular stools. Whole-wheat flour, wheat bran, nuts, beans, and vegetables (such as cauliflower, green beans, and potatoes) are great high-fiber foods. The amount of soluble and insoluble fiber highly varies in different plant foods. To benefit your health, you should aim to eat a wide variety of high-fiber foods.
In short, the fiber in your diet can provide bowel health maintenance, lowered cholesterol levels, blood sugar control, healthy weight loss. Fiber also helps to lower hunger and decrease sugar cravings, improves skin and heart health, is responsible for absorption of important vitamins and minerals, decreases symptoms of constipation, and reduces the risk of cancer.
