The Toledo Exercise and Diet Study: results at 26 weeks

Article Abstract:

Although elevated serum cholesterol has been associated with increased risk of heart disease in numerous studies, the effects of modified dietary habits on cholesterol levels seem to be modest and variable. Sixty-six individuals were identified with high serum cholesterol, high low-density lipoprotein cholesterol, and low general fitness. These subjects were randomly assigned to receive either dietary counselling or dietary counselling in combination with an exercise program. A total of 51 subjects completed the program, 27 in the diet-only group and 24 in the diet and exercise group. Both groups experienced a reduction in total cholesterol, high-density lipoprotein (HDL) cholesterol, and low-density lipoprotein (LDL) cholesterol. Although the reductions were greater in the diet and exercise group, the differences between the two groups were not statistically significant. It is worthy of note that the HDL cholesterol decreased in both groups; the proportional reduction in HDL cholesterol was greater than that for LDL cholesterol. An increase in HDL cholesterol is thought to be desirable, and the reason for its reduction among the subjects in the present study is not known. However, previous studies have suggested that moderate exercise is not sufficient to elevate HDL cholesterol, and that more vigorous exercise is necessary. Since previous studies on the effects of diet and exercise on serum cholesterol have been conducted on subjects with normal or borderline cholesterol levels, the effects of diet and exercise on patients with high serum cholesterol clearly require further research.

Cholesterol-lowering margarines

Article Abstract:

Two margarines that lower cholesterol levels are available in the US. Benecol and Take Control both contain sterols from plants. Plant sterols are similar to cholesterol, which is only produced by animals. They decrease the absorption of cholesterol in the body. It is not clear whether these margarines will lower the risk of coronary heart disease since the plant sterols may also cause coronary artery disease.
