Dietary fiber is the edible parts of plants or analogous carbohydrates that are resistant to digestion and absorption in the human small intestine, with complete or partial fermentation in the large intestine. Dietary fiber consists of non-starch polysaccharides and other plant components such as cellulose, resistant starch, resistant dextrins, inulin, lignins, chitins, pectins, beta-glucan, and oligosaccharides. Dietary fibers promote beneficial physiological effects including laxation, and/or blood cholesterol attenuation, and/or blood glucose attenuation.
Guidelines on Dietary Fiber Intake
Current recommendations from the United States National Academy of Sciences, Institute of Medicine, state that for Adequate Intake, adult men ages 14–50 consume 38 grams of dietary fiber per day, men 51 and older 30 grams, women ages 19–50 to consume 25 grams per day, women 51 and older 21 grams.
The FDA approved health claims for qualified fiber products to display labeling that regular consumption may reduce blood cholesterol levels, which can lower the risk of coronary heart disease, and also reduce the risk of some types of cancer. The FDA allows manufacturers of foods containing 1.7 g per serving of psyllium husk soluble fiber or 0.75 g of oat or barley soluble fiber as beta-glucans to claim that regular consumption may reduce the risk of heart disease. The recommended dose including:
Psyllium seed husk (7 grams per day)
Beta-glucan from oat or barley (3 grams per day)
Source of Dietary Fiber
FDA Recommendation Daily Intake (g)
β-glucan from barley or oat
Psyllium Seed Husk
As of 2018, the British Nutrition Foundation has recommended a minimum fiber intake of 30 grams per day for healthy adults.
Deficiency of Dietary Fiber Intake
On average, North Americans consume less than 50% of the dietary fiber levels recommended for good health. In the preferred food choices of today's youth, this value may be as low as 20%, a factor considered by experts as contributing to the obesity levels seen in many developed countries. We believe the best dietary fiber, barley β-glucan, from Canadian crops can help people in sub-health condition worldwide. That is why we are here for.
