The aim of this study was to investigate the effect of 300 gram per day grape juice for two weeks on LDL-cholesterol le""is in borderline total cholesterol of male and female subjects. The study is a parallel! randomized clinical trial. The subjects random were divided into two groups using simple randomization. The treatment group was given grape juice and nutrition counseling (n = 18) and the control group received nutrition counseling alone, n=l7. Data collected including age, sex, Jevel of education, physical activity, body mass index (BMl), hypercholesterolemic intake of energy, fat, fiber, cho!esteroand polyphenol. Laboratory findings of LDL­ cholesterol levels and BMI examination were done before and after treatment Intake of energy, fut, fiber, cholesterol, and polyphenoi were examined before) during, and after the treatment Statistical analysis, was done using unpaired t and Mann Whitney tests with the signnficant level of 5%. Eighteen subjects. were age 25-44 years old, in the treatment group and fourteen subjects in the control group completed the study. The physical activity index in both groups is categorized as sufficient. The characteristics of the two groups not significantly different at base line (p >0,05). After fourteen days of treatment, ail subjects in the treatment group had energy intake meet the requirement of&9,1 ± 21,6 %whereas the control group average did not 7&,& ± i7.2 %. Intake off in both groups was sufficient, the control group had above recommended intake. Intake of fiber and cholesterol in both group was not significantly different. The average intake of polyphcnol in the treatment group increased significantly higher than in the control group 631,9 (594,4-753,4) and 63,12 (4,5-140,4) mg/day respectively. There was a greater decrease in LOL-cholesterol levels in the treatment group compared to the control group.although not statistically significant (p >0,05).

The aim of this study was to investigate the effect of grape juice (that made from 300 grams of grapes per day) during two weeks on serum NO level in male and female subjects with borderline high total cholesterol level. The study was a field trial Thirty five subjects were selected using certain criteria and randomly (simple randomization) divided into two groups. The treatment group (n=18) received grape juice and nutrition counseling; the control group (n=l7) received nutrition counseling. Data obtained directly from the subjects were age, gender, history of hypercholesterolemia in .subject's family, physical activity, and body mass index, intake of energy, fat, cholesterol~ fiber and polyphenol using food record. Laboratory findings of serum NO level and total cholesterol level were done before and after intervention. For statistical analysis, unpaired t-test and Mann Whitney were used with the level of significance was S%. Eighteen subjects in the treatment group and fourteen subjects in the control group completed the study and analyzed. Mean of age was 35.57±5.20 years old. The physical activity index of bath groups were low. The characteristics of the two groups were closely matched at base line (p>O.OS). After two weeks intervention, subjects? energy consumed in the treatment group achieved the recommended diet, while in the control group was below. The average intake of total fat and cholesterol in both groups achieved the recommended diet, but the fiber intake were below. The average intake of polyphenol in the treatment group was increased significantly than the control group (pQ.05). There were decreased on serum total cholesterol level in bath groups, although not statistically significant (p>O.OS). The effect of gyape juice for two weeks did not significantly increase serum NO level in the treatment group."
