Regular consumption of mango by obese adults may lower blood sugar levels without a negative impact on body weight, a recent study suggests. Research has been published in the journal Nutrition and Metabolic Insights.

Mangos contain mangiferin, an antioxidant that may play a role in lowering blood glucose. The fiber in mangos can also help lower glucose absorption into the bloodstream.

A 12-week pilot study evaluated the effects of mango consumption on anthropometric measurements (eg, height, weight, hip/waist circumference), biochemical parameters (eg, triglyceride, HDL, glucose, HbA1c, insulin), and body composition in 20 obese adults (BMI 30-45kg/m^2). Subjects consumed 10g of freeze-dried mango each day and intake was monitored via 3-day food records assessed at baseline and after 6- and 12-weeks of mango supplementation.

After 12 weeks, subjects had reduced blood glucose (-4.41mg/dL, P<0.001), observed in both males (-4.5mg/dL, P=0.018) and females (-3.6mg/dL, P=0.003). Hip circumference was significantly lower in males (-3.3cm, P=0.048) but not in females. In general, there were no significant changes in triglycerides, HDL, or blood pressure. Further, no changes were observed in overall body weight, hip/waist circumference, waist to hip ratio, percent fat mass or lean mass.

Researchers noted further clinical trials are necessary, especially in those with diabetes.
