What is the fiber manufactured and added to foods and fiber supplements?

The fiber manufactured and added to foods and fiber supplements primarily includes soluble and insoluble fibers, such as psyllium, inulin, and oat beta-glucan. Soluble fiber dissolves in water and can help lower cholesterol and stabilize blood sugar levels, while insoluble fiber adds bulk to the stool and aids in digestion. These fibers are often derived from natural sources like fruits, vegetables, grains, and legumes. They are incorporated into products to enhance their nutritional value and promote digestive health.
