The flesh of cucumbers is a very good source of vitamins A, C, and folic acid. Good to eat when pregnant if you like them. The hard skin is rich in fiber and has a variety of minerals including magnesium, silica, molybdenum, and potassium. Who knew the cucumber was competition to the banana. Cucumber is an excellent source of silica, the mineral that is responsible for strengthening our connective tissue. Connective tissue is what holds our body together, which just may have some effect on cellulite. Don’t forget about the acid they contain. These acids prevent water retention which is why when cucumbers are applied to the eyes at the spa you look great when they are removed.
