Pickles are characteristically low in fat and calories. A typical dill pickle spear contains less than 1 g of fat and only 4 calories. Pickles are also high in vitamin K; one spear supplies 14 mcg or 15 percent of your daily requirement. Vitamin K helps your blood clot after injury, and pickles are a tasty way to obtain this important vitamin.
Unfortunately, pickles are high in sodium and eating a high-sodium diet is strongly associated with risk for developing high blood pressure. The Institute of Medicine’s Food and Nutrition Board recommends that healthy people should consume less than 2,300 mg of sodium a day. One spear of a classic dill pickle contains 306 mg of sodium or 13 percent of the daily recommendation. You can still enjoy pickles, but limit your serving sizes.
