Cucumbers are the fruit of the Cucumis sativus plant, a member of the Cucurbitaceae family. They are generally long and cylindrical, but some varieties can be short and round. Cucumbers are generally green, with thin skin that can be slightly hairy or rough.
Nutritional, cucumbers are low in calories and high in water content. They are also rich in vitamin C, vitamin K, potassium, manganese, and other vitamins and minerals. Cucumbers promote hydration, aid digestion, and improve skin health.
