Mango is a tropical, sweet, carbohydrate-rich, fruit that, perhaps unexpectedly, may improve blood sugar.
In a 12 week study on obese individuals, eating 10 grams per day of dried mango pulp significantly reduced their fasting blood sugar.88
That amount corresponds roughly to 57 grams (2 ounces) of raw mango.
As an added benefit, mango has a relatively low glycemic index (impact on post-meal blood sugar levels) compared to other tropical fruits, such as banana, pineapple, durian, and rambutan.89
Animal studies also demonstrated the antidiabetic effects of mango. For example, mice fed a fattening diet became insulin resistant, but adding mango as 1% of the diet diminished weight gain, increased carbohydrate tolerance, and reduced insulin resistance.90
