[Oat bran as lipid-lowering agent?].

: Hypercholesterolemia is one of the major risk factors for ischemic heart disease and for the development of atherosclerotic plaques. Water soluble plant fibers do exert a binding of intestinal cholesterol and are not digested or metabolized. We have investigated the effect of a highly water soluble fiber containing oat brain on serum cholesterol concentrations in 14 volunteers (nine males, five females, age 39 to 67 years, serum cholesterol concentration: 7.14 +/- 0.80 mmol/l; x +/- SD) during an intervention with 50 g oat brain per day for nine weeks. We have documented in the whole study population a modest, but significant reduction of serum cholesterol levels of 4.2% (p less than 0.05) at six weeks; however at nine weeks the efficacy of this regimen was less pronounced (3.2%, p = n.s.) speaking for a decreased compliance although this regimen was well tolerated and accepted. In subsets of high risk volunteers for coronary heart disease of male gender (n = 9), with hypercholesterolemia (n = 8) or essential hypertension (n = 8) the reduction of serum cholesterol levels was more consistent (5.6%, p less than 0.05) with no change in normolipemic volunteers.
