Thinking about how to prevent getting the flu this year? Try eating a well-balanced diet and increase your intake of organic fruits and vegetables. These type foods contain plenty of natural occurring vitamins such as Vitamin E, Vitamin C and other antioxidant vitamins. Antioxidant vitamins fight destruction of healthy cells in your body. A lack of powerful antioxidant vitamins leave you more vulnerable and less resistant to seasonal flu. Top antioxidant fruits and vegetables include beans, blueberries, strawberries, broccoli, cranberries, artichoke, apples, plums, oranges, and potatoes.
