Barley Beta-Glucans
DESCRIPTION
Soluble barley fiber containing 55% Beta-Glucans. Beta-Glucans are the soluble dietary fiber component of cereals, thought to have serum cholesterol reducing activity. The Beta-Glucans can be concentrated from barley by alcohol extraction.
INDICATIONS
Beta-Glucans have received a lot of media attention due to reports identifying them as the agent in oat bran and barley capable of reducing serum cholesterol, and stimulating the immune system (the (1-3)-Beta-Glucan). Beta-Glucans can be used in place of oat bran in nutritional supplements and food products. Beta-Glucans are also useful in cosmetics, in skin care products. The product is also useful wherever additional anti-oxidants are needed due to its content of tocotrienes. Soluble Beta-Glucans can also be used in weight loss formulas.
PHYSIOLOGY
Barley has been reported to reduce serum cholesterol in animals and humans. Soluble dietary fibers such as Beta-Glucans are important nutrients for the diet, to help maintain healthy levels of cholesterol in the blood.
BIOCHEMISTRY
(1-3)(1-4)-linked Beta-D-Glucan is a polysaccharide, or soluble fiber component, found in a variety of cereals. Beta-Glucans occur in highest amounts in the endosperm of barley and oats. Barley soluble fiber is also rich in tocotrienes, which are antioxidants related to Vitamin E.
TOXICITY, CAUTIONS & CONTRAINDICATIONS
No known toxicity.
SUGGESTED USE
Up to 20 grams per day of Beta-Glucans, taken with or mixed into meals. The optimal level of fiber in the diet is 30 to 50 grams per day of mixed soluble and insoluble fibers for adults.
