Health implications of barley β-glucans
Abstract
Barley grain is an important source of β-glucan, which is a polysaccharide that is part of soluble dietary fiber (DF). Soluble fiber has better hydration properties, as does fermentation and the production of short chain fatty acids (SCFA). β -glucans provide numerous benefits to human health. The objective of this review is to analyze the current evidence and report on the modifications it undergoes during consumption, its addition and functional properties of barley β-glucans, allowing to obtain the health benefits (hypolipidemic, hypoglycemic and hypocholesterolemic). According to the review, they have been found to help lower total cholesterol and LDL-C, prevent visceral fat and the risk of diverticular disease, as well as cause delayed gastric emptying and attenuation of the absorption rate of glucose in the small intestine. They can also help relieve gastric lesions and participate in anticancer activity and lung carcinoma; also, its topical application improves the healing of diabetic and venous ulcers. Evidence from recent studies consistently shows that β-glucan consumption is associated with multiple benefits, from decreased macronutrients absorption to wound healing. This further highlights the importance of its consumption and application.
