If you love eating tree nuts, good news!

People who eat tree nuts (almonds, walnuts, cashews—you name it) have fewer risk factors for heart disease, diabetes and metabolic syndrome.

In the new study, the nut lovers had a lower body weight, as well as a lower body mass index and waist circumference.

BUT this doesn’t mean you should go nuts by any means—even a small handful can give you big heath benefits! And even beauty foods could backfire.
