Vitamin C is important for so many functions in the human body and it’s something that needs to be replenished daily. This essential vitamin helps keep your immune system strong and helps wounds heal faster. It’s a crucial component of a connective tissue called collagen that supports your skin, so not getting enough vitamin C every day may lead to more winkles and tired-looking skin. Vitamin C is also a powerful antioxidant that helps protect the cells in your body from damage due to free radicals from the environment, sun damage and as a result of normal metabolism. Vitamin C is found in fruits and vegetables. The foods with the most vitamin C include oranges, tangerines, grapefruit, kiwi guava, strawberries, broccoli, peppers and potatoes. Women need about 90 milligrams of vitamin C every day — which can be accomplished by eating a cup of freshly sliced strawberries, a glass of orange juice, or a whole grapefruit. In general, if you eat fruits and vegetables, or fortified breakfast cereals, with every meal you should get all the vitamin C you need. Here’s a pro tip: vitamin C doesn’t hang around long once fresh fruits and vegetables are peeled, cut chopped or slice. Since vitamin C is an antioxidant, it starts to deteriorate when it’s exposed to air.
