Are cucumbers healthy?

Cucumbers are extremely healthy and provide a variety of health benefits. According to Mercola.com, the nutrients found in cucumbers have been directly linked to reducing inflammation and reducing the risk of cancer and Alzheimer's disease.

A single cucumber contains rich nutrients, such as vitamin A, vitamin C, iron and calcium, according to the United States Department of Agriculture. Because cucumbers are mostly comprised of water, each cucumber has only about 30 calories, so carbohydrate, fat and protein contents are extremely low. Cucumbers also contain antioxidant properties, such as kaempferol, an antioxidant flavonoid that may help fight cancer and prevent heart disease, according to Mercola.com.
