Ans:

Dietary fiber is a food nutrient that is generally indigestible, mainly from the cell walls of plants, and contains cellulose, hemicellulose, resins, pectin, and lignin.

Fiber dissolved in water can be divided into two basic types: water-soluble fiber and insoluble fiber. Water-soluble fibers include resins, pectin and some semi-fibers. Common foods such as barley, beans, carrots, citrus, flax, oats and oat bran are rich in water-soluble fiber. Water-soluble fiber slows down digestion and excretes cholesterol most quickly, so it can keep blood glucose and cholesterol in the blood at the optimal level, and it can also help diabetic patients to lower their insulin and triglycerides.

Insoluble fiber includes cellulose, lignin, and some semi-fibers, as well as wheat bran, corn bran, celery, fruit peels, and root vegetables from food. Soluble fiber reduces the risk of bowel cancer, prevents constipation and diverticulitis by absorbing toxins from food, and reduces the amount of toxins excreted by bacteria in the digestive tract. Most plants contain both soluble and insoluble fiber, so eating a balanced diet of soluble and insoluble fiber can yield different benefits.

Benefits of Dietary Fiber:

◇Maintains a healthy digestive system

◇Strengthens the immune system

◇Lowering cholesterol and high blood pressure

◇Lowering insulin and triglycerides

◇Laxative, diuretic, and stomachic

◇Prevents cardiovascular disease, cancer, diabetes, and other diseases

◇Balances the body's health. Fiber cleanses the digestive walls and strengthens digestion. Fiber also dilutes and accelerates the removal of carcinogens and toxins from food, protecting the delicate digestive tract and preventing colon cancer. Fiber slows down digestion and maximizes cholesterol excretion, so blood sugar and cholesterol are kept at optimal levels.
