Look beyond apples and oranges: Obese adults who ate about half a mango a day for 12 weeks saw a significant reduction in blood sugar levels, according to research presented at the Federation of American Societies for Experimental Biology.

The results likely translate to normal-weight men, too, says study author Edralin Lucas, Ph.D. Mango’s power could lie in active compounds like plant polyphenols, which may inhibit the development of fat cells and reduce their size, says Lucas. The fruit is also high in fiber, reducing the absorption of sugar, she adds.
