The blood-glucose and cholesterol-lowering efficacy of oat beta-glucan is determined by the amount and molecular weight of beta-glucan that becomes solubilized in the gastrointestinal tract, which directly dictates the resulting digesta viscosity.
To get blood sugar and cholesterol benefits from oats, choose products where the beta-glucan remains soluble and has a high molecular weight. Processing methods like extensive extrusion, baking into bread, or freeze-thaw cycles can degrade the beta-glucan or reduce its solubility, rendering it ineffective regardless of the total fiber content. Look for minimally processed oats or specific concentrates that maintain viscosity.
In conclusion, both the amount and MW of b-glucan that are solubilised in the GIT need to be considered when assessing the blood-glucose and cholesterol-lowering properties of oat-containing foods.
Why this rating
The paper cites multiple human intervention trials and in vitro models establishing a clear inverse linear relationship between viscosity and glycemic response.
