Regular mango consumption by obese adults could help lower blood sugar levels without negatively impacting on weight, according to new research published in the Nutrition and Metabolic Insights journal. 

The U.S. National Mango Board (NMB) said the findings were particularly important given the fact 34% of adults in the country had been classified as obese, putting them at higher risk of developing conditions such as type 2 diabetes and metabolic syndrome.

"We are excited about these promising findings for mangos, which contain many bioactive compounds, including mangiferin, an antioxidant that may contribute to the beneficial effects of mango on blood glucose," lead study author and Oklahoma University professor Dr. Edralin Lucas said in a release.

"In addition, mangos contain fiber, which can help lower glucose absorption into the blood stream.

"Our results indicate that daily consumption of 10 grams of freeze-dried mango, which is equivalent to about one-half of a fresh mango (about 100 grams), may help lower blood sugar in obese individuals."

This pilot study was designed to investigate the effects of mango consumption on various body measurements, biochemical parameters, and body composition in obese adults.

Participants completing the 12-week study included 20 adults aged from 20 to 50 years old with a high Body Mass Index (BMI). The study subjects were asked to maintain their usual diet, exercise habits and regimen of regularly prescribed medications.

Each day during the study period participants consumed 10 grams of freeze-dried mango, after which time a series of body composition and blood analyses were carried out.

The researchers found that after 12 weeks, both male and female participants had reduced blood glucose levels, while no changes were observed in overall body weight, hip or waist circumference, or lean mass.

"We believe this research suggests that mangos may give obese individuals a dietary option in helping them maintain or lower their blood sugar," Lucas said.

"However, the precise component and mechanism has yet to be found and further clinical trials are necessary, particularly in those that have problems with sugar control, such as diabetics, are necessary."

The release added results from this pilot study could have been influenced by a number of factors including lack of a control group, duration of mango supplementation, and inaccurate self-reporting of dietary intake or physical activity.
