Fiber, also known as dietary fiber or roughage, are the parts of plant foods that the body cannot digest or absorb. There are two main types of fiber—soluble fiber and insoluble fiber. Soluble fiber dissolves in water and forms a gel-like substance in the digestive tract. Insoluble fiber does not dissolve in water. Both types are important for maintaining good gut health.

Soluble fiber's role in digestion and health

Soluble fiber helps slow down digestion and the absorption of sugar and carbohydrates. This moderates blood sugar and insulin levels. Soluble fiber ferments in the gut and produces short-chain fatty acids that nourish the cells of the colon. It also binds to cholesterol-rich bile acids in the intestine and transports them out of the body. This lowers LDL or "bad" cholesterol levels. Food sources high in soluble fiber include oats, beans, flaxseeds, nuts and fruits like berries and apples.

Insoluble fiber and regularity

Insoluble fiber adds bulk to stool and softens it. This promotes regular bowel movements and prevents constipation. Insoluble fiber remains intact as it passes through the digestive tract. It literally acts like a broom sweeping waste through the intestines. Sources of insoluble fiber include whole-grain breads and cereals, whole wheat pasta, brown rice, vegetables, and fruits with the skin such as apples.

Why Fiber Supplements?

Most people do not get the recommended daily amounts of Fiber Supplements through diet alone. The average American diet provides only around 15 grams of fiber per day whereas the recommended amount is 25 to 38 grams for women and 38 to 50 grams per day for men. Fiber addition can help bridge this gap. They usually contain a blend of soluble and insoluble fibers in easily digestible powder or capsule form.

Benefits of Fiber Supplements

Taking a fiber supplement regularly provides the following benefits:

- Promotes regularity and prevents constipation: Insoluble fiber adds bulk to stool and helps it pass through the intestines smoothly. This prevents hard and dry stools that characterize constipation.

- Lowers risk of heart disease: Soluble fiber binds to cholesterol and removes it from the body. This in turn lowers LDL or "bad" cholesterol levels. Over time, this reduces plaque buildup in arteries and lowers heart disease risk.

- Manages blood sugar levels: Soluble fiber slows down carbohydrate absorption and moderates blood sugar spikes after a meal. This helps prevent hyperglycemia or high blood sugar related health issues.

- Aids in weight management: Fiber gives a feeling of fullness and prevents hunger pangs. It also bulks up stool, taking up space in the digestive tract. This suppresses appetite and prevents overeating.

- Reduces risk of diverticulitis: A high-fiber diet and fiber addition help move stool through the intestines easily. This reduces pressure in the colon walls and prevents pouches or sacs from forming. These sacs sometimes get infected causing diverticulitis.

- May lower cancer risk: Fermentation of soluble fiber in the colon produces short-chain fatty acids that protect colon cells from damage. Fiber also binds to carcinogens in the large intestine and aids their removal. This prevents exposure of colon cells to these cancer-causing substances.
