Dietary fiber or roughage is the indigestible portion of food derived from plants. It has two main components:
- Soluble fiber, which dissolves in water, is readily fermented in the colon into gases and physiologically active byproducts, and can be prebiotic and viscous.
- Insoluble fiber, which does not dissolve in water, is metabolically inert and provides bulking, or it can be prebiotic and metabolically ferment in the large intestine. Bulking fibers absorb water as they move through the digestive system, easing defecation
Found mainly in fruits, vegetables, whole grains and legumes — is probably best known for its ability to prevent or relieve constipation. But foods containing fiber can provide other health benefits as well, such as helping to maintain a healthy weight and lowering your risk of diabetes and heart disease
- Blood sugar control: Soluble fiber may help to slow your body’s breakdown of carbohydrates and the absorption of sugar, helping with blood sugar control.
- Heart health: An inverse association has been found between fiber intake and heart attack, and research shows that those eating a high-fiber diet have a 40 percent lower risk of heart disease.
- Stroke: Researchers have found that for every seven-grams more fiber you consume on a daily basis, your stroke risk is decreased by 7 percent.
- Weight loss and management: Fiber supplements have been shown to enhance weight loss among obese people, likely because fiber increases feelings of fullness.
- Skin health: Fiber, particularly psyllium husk, may help move yeast and fungus out of your body, preventing them from being excreted through your skin where they could trigger acne or rashes.
- Diverticulitis: Dietary fiber (especially insoluble) may reduce your risk of diverticulitis – an inflammation of polyps in your intestine – by 40 percent.
- Hemorrhoids: A high-fiber diet may lower your risk of hemorrhoids.
- Irritable bowel syndrome (IBS): Fiber may provide some relief from IBS.
- Gallstones and kidney stones: A high-fiber diet may reduce the risk of gallstones and kidney stones, likely because of its ability to help regulate blood sugar.
- High-fiber foods are good for your health. But adding too much fiber too quickly can promote intestinal gas, abdominal bloating and cramping. Increase fiber in your diet gradually over a period of a few weeks. This allows the natural bacteria in your digestive system to adjust to the change.
Also, drink plenty of water. Fiber works best when it absorbs water, making your stool soft and bulky.
