Soluble fiber is a type of dietary fiber that dissolves in water and forms a gel-like substance during digestion. It is found in many plant-based foods, including fruits, vegetables, whole grains, and legumes. Soluble fiber is important for digestive health, as it helps to slow down digestion and support regular bowel movements. It also helps to lower LDL (bad) cholesterol and balance blood sugar levels, reducing the risk of heart disease and diabetes. Some good sources of soluble fiber include oats, peas, beans, apples, citrus fruit, carrots, barley, and psyllium. To increase your intake of soluble fiber, you can eat more fresh fruits and vegetables, legumes, and grains, or take fiber supplements if needed.
