Oranges are excellent for increasing vitamin C levels, but they are also packed with other minerals, including potassium, magnesium, and several antioxidants. Oranges are a hydrating snack before or after a workout because they are primarily made of water. The winter fruit contains an anti-inflammatory antioxidant called hesperidin, which has been connected to cardiovascular, immunological, cognitive, and bone health. The fruit also helps your eyesight because it contains beta-carotene, which the body converts into vitamin A. So drink up! What is your favorite: orange or pineapple juice?
