Cucumber Facts

Cucumbers are a member of the cucurbitaceae family, along with melons, squash and pumpkins. They are made up of 96% water. They are mild tasting, low in calories, low fat, low cholesterol and low sodium. Cucumbers contain Vitamin C, Vitamin K, magnesium, potassium and manganese. They contain pectin, a soluble fiber that helps with regular bowel movements. One cup of cucumber slices is about 16 calories and 150 mg of potassium. A whole medium cucumber with the peel contains 440 mg potassium—so portion control is important.

Cucumbers can be stored in a fridge up to 1 week. Some are treated with a waxed coat after they are picked. It is best not to wash before storing in the refrigerator. However, be sure to wash thoroughly or peel before eating if waxed. If only a partial cucumber is used, the recommendation is to cover the end with plastic wrap and store in the refrigerator.
