Cabbage (Water content: 92%)

Cabbage is a cruciferous vegetable that is extremely healthful. It has a low-calorie content but is abundant in fiber and nutrients. It's also high in vitamin C, vitamin K, folate, and a number of trace minerals, all of which may have health-promoting properties.

Vitamin C, for example, is widely recognized for its anti-inflammatory properties and has been demonstrated to reduce the risk of chronic diseases such as diabetes and heart disease. Cabbage also contains glucosinolates, which are antioxidants that are considered to protect against some cancers, such as lung cancer. In addition, cabbage is commonly fermented into sauerkraut, which is high in water and may help with digestion.
