Abstract

The aim of this study was to assess the effect of 6-week vegetable juice supplementation (360 ml/day) on serum lipid profiles and antioxidant activity in college women. Twenty women (mean age: 21) with normal life style and dietary pattern and who are free of any specific diseases were recruited among the student in S women's university. The subjects consumed vegetable juice to take part in an uncontrolled clinical trial for a 6-week intervention period. While there was no difference in the concentration of total cholesterol and HDL-cholesterol, serum concentrations of TG and HDL/LDL ratio were significantly reduced by 22% (p = 0.013) and 6% (p = 0.007) respectively. Significant decrease in malondialdehyde (p = 0.000) was accompanied by an increase in the activity of serum antioxidant enzymes, such as GSHPx (p = 0.000), SOD (p = 0.007). It was also found that total antioxidant status was improved by 5.4% (p = 0.009). Serum parameters were all changed without affecting body mass index, waist and hip circumferences, or nutrient intakes after six week of supplementation. This study demonstrated that the supplementation regular meals with vegetable juice can favorably affect serum lipid profiles and antioxidant systems, and hence could contribute to reduce the risks of chronic diseases in college women.
