     THE IMPORTANCE OF VITAMIN C

  In the past people suffered from a disease called scurvy. Their gums bled, their skin became rough, their wounds did not heal and their muscles wasted away. The cause of these symptoms was a lack of vitamin C, people ate preserved meats and foods and could not get fresh vegetables and fruits.
    The best sources of vitamin C are oranges, lemons, grapefruit, cantaloupes, strawberries, and fresh vegetables. These fruit must be fresh because vitamin C is destroyed by heat, storage, or exposure to air.
    Although today more people take vitamin C pills than any other supplement, some people still have scurvy, including some of the elderly, alcoholics, and the chronically ill.
      Research shows that vitamin C reduces the severity of colds and can help prevent cancer. There is also evidence that vitamin C prevents heart diseases, speeds wound healing, helps prevent gum disease, and helps protect us from pollutants such as cigarette smoke. Some recent research also show that vitamin C has a positive effect on metal disorders and increases life span.
