The specific type of fiber in oats responsible for its cholesterol-lowering effects is called beta-glucan.
The beta-glucan fiber in oats contributes to a reduced risk of type 2 diabetes by increasing the viscosity of the contents in the stomach and small intestine. This "gel-like" consistency slows down the absorption of sugar, leading to better insulin control.
Beyond beta-glucan, oats contain polyphenols, including a specific type that may have beneficial impacts on blood pressure, inflammation, oxidative stress, and blood vessel function.
This video discusses the health benefits of oats, focusing on their impact on cholesterol and blood sugar levels. Professor Sarah Berry explains the role of beta-glucan fiber in oats, its effect on cardiovascular health and type 2 diabetes risk, and other beneficial compounds. The video also addresses concerns about pesticide residues, specifically glyphosate, in oats and provides guidance on whether to worry about them.
