Cauliflower (Water content: 92%)

Cauliflower is a highly healthy and hydrating vegetable that you should include in your diet. Cauliflower contains more than one-fourth cup (59 ml) of water and 3 grams of appetite-suppressing fiber in one cup (100 grams).

With only 25 calories per cup, its high water content contributes to its low caloric intake. Cauliflower also contains more than 15 vitamins and minerals, including choline, a nutrient that isn't found in many foods. Choline is a vitamin that is necessary for brain function and metabolism. Cauliflower may be used to substitute less hydrating grains by finely chopping it into "rice" or making a cauliflower-based pizza crust.
