• Water soluble fiber of beta glucan
• Also contains insoluble fiber found in Oat
• Has positive effect for LDL cholesterol reduction, diabetes
mellitus Type 2, Cardiovascular hypertension, dll
• Slowing down the sugar absorption after meal
• Insoluble fiber adds mass to the digested products to be
excreted out
• More than100 scientific papers on Oat Beta Glucan

MECHANISM EXPLANATION
Barrier against food-cholesterol
from being absorbed
Food supplies 20% of cholesterol
Avoiding cholesterol degradation
product (bile acid) from re-
absorption
Bile acid is a degradation product of
cholesterol. Bile acid and cholesterol are
delivered to the intestine to be re-
absorbed. Beta-glucan binds to this
complexes then remove them all.
Removing blood cholesterol from
the circulation
Because the beta-glucan/cholesterol/bile
acid complexes have been removed then
the cholesterol is further taken from the
blood to be processed in the gall resulting
in the low blood cholesterolSource : Heart UK, The Cholesterol Charity
