This is a review and meta-analysis of 67 controlled trials into the effects of dietary soluble fibre on blood cholesterol.
Over all, soluble fibre intakes of betwen 2 and 10 grams per day were related to significant but small decreases in total cholestrol and LDL cholesterol. No effct was seen in triglycerols or HDL cholestrol.
No significant differences were found between different sources of soluble fibre when oat bran, psyllium and pectin were compared. Insufficient information was available on guar gum.
Cholesterol-lowering effects of dietary fibre - a meta-analysis.
Am J Clin Nutr 69, (1999)
Editor's Note: HDL is High Density Lipoprotein which carries about a third to a quarter of the body's blood cholesterol. It is beneficial lipoprotein, generally regarded as warding off heart attacks and strokes. Its level in the blood can be increased by physical activity, and also by the taking of aged garlic, according to recent research.
LDL is Low Density Lipoprotein, often called "bad" cholesterol because high levels of LDL in the blood have been found to be associated with risk of strokes and arteriosclerosis. LDL favours the laying down of fatty deposits in the arteries.
