Fruit pectin belongs to a class of dietary fiber, with what role?
A, what is dietary fiber?

Dietary fiber is a carbohydrate that can not be digested by the body, divided into two categories of insoluble and water-soluble fiber. Cellulose, hemicellulose and lignin are three common types of insoluble fibers found in plant cell walls; while pectin and gum are water-soluble fibers found in non-fibrous materials in nature.

Two, the importance of dietary fiber.

Dietary fiber plays a pivotal role in promoting good digestion and excretion of solid waste. A moderate amount of fiber can make the food in the intestines increase in size and become softer, promote intestinal peristalsis, which speeds up the speed of defecation, preventing constipation and reducing the risk of intestinal cancer.

In addition, fiber can regulate blood sugar and help prevent diabetes. It can also reduce the absorption of fat in the digestive process, thus lowering the level of cholesterol and triglycerides in the blood and preventing hypertension and cardiovascular diseases.

Three, the daily intake standards:

Recommended by relevant international organizations of the daily intake of dietary fiber: the American Cancer Society recommended standards for each person 30 to 40 grams per day, the European **** the same body Food Science Council recommended standards for each person 30 grams per day.

Four, what food contains the most dietary fiber?

Brown rice and embryonic teeth refined rice, as well as corn, millet, barley, wheat hulls (rice bran) and wheat flour (black bread material) and other miscellaneous grains; in addition, root vegetables and seaweed in the more dietary fiber, such as burdock, carrots, beans, red beans, peas, potatoes and wakame.

Dietary fiber is generally not easy to be digested food nutrients, mainly from the cell wall of plants, containing cellulose, hemicellulose, resin, 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 insulin and triglycerides.

Non-soluble fibers include cellulose, lignin, and some semi-fibers, as well as wheat bran, corn bran, celery, fruit peels, and root vegetables from food. Insoluble fiber reduces the risk of bowel cancer, prevents constipation and diverticulitis by absorbing toxic substances 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 provide different benefits.

Benefits of dietary fiber:

◇Maintains digestive health

◇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 balance. Fiber cleanses the digestive wall 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.
