About this food

Understanding this nutrition reference

Cucumbers are crisp, cylindrical vegetables with a mild, refreshing flavor and very high water content. They are usually eaten raw in salads, sliced as a snack, or pickled. Varieties include common slicing cucumbers and smaller pickling types.

Nutritionally, cucumbers are one of the lowest-calorie vegetables. Per 100 g they provide about 15 kcal, 3.6 g of carbohydrates, 0.7 g of protein, and 0.1 g of fat, with 0.5 g of dietary fiber, 2 mg of sodium, and 16 mg of calcium.

Because cucumbers are mostly water, a large portion contributes very few calories. They are often eaten with the skin on, which adds fiber. For accurate tracking, weigh cucumber with or without skin as consumed, and use the serving sizes below.
