One Apple a Day

Often called a "miracle food" and a "nutritional powerhouse," an apple a day really may keep the doctor away as they're one of the healthiest foods a person can eat. These round and juicy fruits are high in fiber and vitamin C, and they are also low in calories, have only a trace of sodium, and no fat or cholesterol.

"Apples are high in polyphenols, which function as antioxidants,” said Laura Flores, a nutritionist based in San Diego. “These polyphenols are found in both the skin of the apples as well as in the meat, so to get the greatest amount of benefits, eat the skin of the apple.
