Researchers at the Hebrew University of Jerusalem found that Israeli Jaffa Sweetie can help reduce blood cholesterol levels and increase blood antioxidant activity. The study had 72 patients who had elevated cholesterol levels and who had bypass surgery taking supplements of Sweetie juice for 30 days. The participants, aged 43 to 71, were split into 3 groups of 24 each. Group 1 received a daily supplement of 100 mL of the juice; group 2 received 200 mL; and group 3, the control group, received none.
The results of the study, reported recently in the Journal of Agricultural and Food Chemistry, indicated a reduction in low-density lipoprotein ("bad") cholesterol and an increase in blood antioxidant activity in patients in the 2 groups who drank the juice, compared with the control group. The patients who consumed the highest daily supplement of juice showed a major increase in blood albumin and a decrease in blood fibrinogen levels.
