In fact, cucumbers are made up of about 96% water. In addition, peeling can reduce the amount of fibre and some vitamins and minerals.
Antioxidants are molecules that prevent oxidation. Oxidation is a chemical reaction that forms highly reactive atoms with unpaired electrons called free radicals. The accumulation of these harmful free radicals can lead to many chronic diseases. In fact, free radical-induced oxidative stress is associated with cancer and heart, lung and autoimmune diseases. Fruits and vegetables, including cucumbers, are rich in beneficial antioxidants that reduce the risk of these diseases.
Water is very important to body function and plays many important roles. It involves processes such as temperature regulation and waste and transport of nutrients. In fact, proper hydration can affect everything from physical properties to metabolism.
