In the 1500’s one ship’s captain found a witchdoctor in Newfoundland that had a magic potion of pine needles that cured his sailors. In olden days many sailors got scurvy. It was a real problem for the seamen but no one knew what was causing it.
In 1747 a Doctor James Lind thought that the disease might be caused by the poor diet the sailors were eating so he tried an experiment. He divided some of the sailors into pairs and added the following things to each pairs diet. 2 had cider 2 had vinegar 2 had acid, alcohol ginger and cinnamon 2 had garlic, mustard and herbs 2 had seawater 2 had oranges and lemons
Which sailors were cured? • The 2 sailors that ate the oranges and lemons were cured of their scurvy. This proved that something in these fruits was the cure but they still didn’t know exactly what it was. From then on the sailors were fed citrus fruit and in England became known as “Limeys”.
How Often Do I Need Vit. C? • Because Vitamin C is water soluble it is not stored in the body. Any extra that you eat is discarded from the body. Therefore, you should eat a Vitamin C rich food every day!
