摘要
Phytosterols (PSs) are reported to lower the serum total cholesterol and low-density lipoprotein cholesterol concentrations enriched in some fatty foods, such as margarine. However, these high-fat foods are not very suitable for older people. Soy milk is the favorite food for elderly people in China; therefore, we hypothesized that the consumption of soy milk powder supplemented with PSs would decrease the serum cholesterol levels in older Chinese people independent of the genotypes of apolipoprotein E (ApoE). Mild to moderate hyperlipidemic patients (n = 170) were recruited from different communities and treated with placebo soy milk powder or 3.4 g PS esters enriched soy milk powder (2.0 g/d free PS in 30 g soy milk powder). The fasting serum lipid profiles at the baseline and after 3 and 6 months of intervention were measured. The ApoE genotype was also determined. After 3 months of PS intervention, the serum lipid profile was not changed significantly in either group. The serum total cholesterol, low-density lipoprotein cholesterol, and non high density lipoprotein cholesterol levels decreased by 9.3%, 11.4%, and 12.6%, respectively, in the PS group at the end of the intervention (6 months) compared with the control group, whereas the serum high-density lipoprotein cholesterol and triglyceride levels were not affected significantly. In the PS group, both the ApoE3 and ApoE4 carriers had a similar response to PS consumption. These findings suggested that PS-fortified soy milk powder was effective in lowering the serum cholesterol levels in older Chinese volunteers with mild to moderate hypercholesterolemia in both the ApoE3 and ApoE4 carriers.
