Scientists believe the fat-busting powers of the fruit, grown in Italy and the U.S., may be partly due to its high levels of anthocyanin. This red pigment that gives the orange its deep colour is a type of antioxidant, a natural chemical that helps ward off diseases. The juice of the blood orange stops mice piling on weight when fed a high-fat diet, research shows. The juice damages the ability of cells called adipocytes to accumulate fat, University of Milan researchers told the International Journal of Obesity. Adipocytes are found mostly around the waistline and absorb fat from food to store as energy.
