Dietary fiber forms one of the most essential nutrients in the diet. It is required in adequate amounts for sound digestion and proper functioning of the digestive system. There are many ways fiber rich foods promote sound health.
Foods rich in dietary fiber have low glycemic index. This prevents sudden surges in insulin levels and fat deposition.
Soluble fiber helps regulate LDL (bad) cholesterol and total cholesterol levels.
Soluble fiber balances intestinal pH and stimulates intestinal fermentation. This helps keep the intestines healthy.
Insoluble fiber adds bulk to the diet which alleviates constipation.
Dietary fiber helps with weight loss. It promotes satiety and reduces appetite.
It is now recognized that there are a number of diseases which are, at least in part, caused by a lack of dietary fiber in the diet.
Gastrointestinal disorders: Constipation, bloating, flatulence, piles, diverticulosis, hiatal hernia, hemorrhoids, cancer of colon
Metabolic disorders: Obesity, diabetes, gallstones
Cardiovascular disorders: Coronary artery disease (CAD), high blood pressure, stroke
There is an inverse relationship between the amount of fiber consumed and the prevalence of various diseases-higher the intake of dietary fiber, lower is the incidence of chronic disorders.
