Effect of Mulberry (Morus rubra) Juice on Blood Glucose and Satiety in Healthy Subjects
Keywords:
mulberry juice, blood glucose, satietyAbstract
Mulberry fruit contains anthocyanin which is an antioxidant in the flavonoid group, and it helps to regulate blood glucose and insulin levels in diabetic rats. The objective of this study was to determine the effects of a mulberry juice on blood glucose and satiety levels in healthy subjects compared to the control group. A cross-group study was conducted on 16 subjects, mean aged 21.00 ± 0.83 years and BMI 20.01 ± 1.28 kg/m2. All subjects were measured body composition, and then randomly selected to consume two research drinks which would be washed out for one week apart. The control drink was 180 ml of glucose and fructose solution, and the test drink was 180 ml mulberry juice. Subjects were measured their blood glucose levels, satiety scales, body temperature, blood pressure and heart rate at 0 minutes before drinking and after drinking at 30, 60, 90 and 120 minutes. The results showed that after drinking mulberry juice at 30 minutes, the blood glucose levels of mulberry juice group were significantly lower than the control group (p<0.05), while satiety levels, body temperature, and blood pressure were not statistically difference compared to the control group. In conclusion, mulberry juice may lower blood glucose levels after 30 minutes of drinking.
