Dietary fiber, exercise and selected blood lipid constituents
1980
The effects of dietary fiber and exercise on serum cholesterol and lipoproteins are examined. Cholesterol high-density lipoprotein (HDL), presumed to be a protective factor in coronary heart disease, rises in response to even moderate exercise. This has been documented in a number of studies. Cholesterol usually accounts for only 20-25% of total plasma cholesterol, but its concentration relates inversely with coronary artery disease risk. Certain dietary fibers (e.g., guar gum, citrus pectin, wheat, or oat bran, and soybean hulls), in common with certain other dietary changes, depress total serum cholesterol and cholesterol low-density lipoprotein selectively, without affecting HDL cholesteol levels. Most results further indicate that the selective alterations in serum lipoprotein induced by such fibers may reduce atherosclerosis risk in some individuals if such beneficial alterations are maintained for prolonged periods. Further study is needed, however, before definitive conclusions can be reached about possible protective effects of dietary fiber against coronary artery disease. (wz)
