Organic Oatbran (Avens sativa)
Oats have numerous uses in foods; most commonly, they are rolled or crushed into oatbran and oatmeal, or ground into fine oat flour.
The common oat (Avena sativa) is a source of soluble and insoluble fibre; soluble fibre is known as beta-glucan. It exists as low or high molecular weight molecules, both of which are equally effective towards normalising cholesterol and blood sugar levels. Fibre is vital for a healthy intestine, providing a “bulking” agent for the stool. In sufficient quantities of 3 gm or more a day, beta-glucan can significantly lower cholesterol, especially “bad” LDL cholesterol (Braaten, et al., 1994). Most studies have shown that oats reduce LDL concentrations without affecting “good” HDL concentrations.
The fibre in oatbran can bind with cholesterol-rich bile to increase the amount of cholesterol that is excreted. High levels of cholesterol can result in a build-up of plaque in the arteries, resulting in high blood pressure, heart disease and increased risk of heart attack or stroke; reducing cholesterol therefore reduces the risk of a build-up of atherosclerotic plaques and so contributes to the prevention of cardiovascular disease.
Beta-glucan may help to limit the increase in blood sugar after a meal, which is potentially helpful for diabetics
