Grapefruit

A powerhouse for heart health, grapefruit contains vitamin C, folic acid, and potassium, along with pectin, a soluble fiber that may be a strong ally against atherosclerosis. Pink and red varieties also have vitamin A and lycopene, a phytochemical that protects arterial walls from oxidative damage. To get the juiciest specimens, select fruits heavy for their size and make sure to try them in this refreshing Grapefruit Avocado Salad.
