In 1931, it was discovered that some unknown substance present only in certain foods was necessary for good health. This substance was what is now called “Vitamin A”.

  Vitamin A's biggest job is to keep the eyes going. Without it, people and animals get “night blindness” and eye problems. Lack of Vitamin A for a long time can even cause total blindness, particularly among children. This had a chance to be tested in Denmark during World Was I. Because of food shortage, many children had to eat man-made butter and skim milk(脱脂奶), which contains no Vitamin A. Soon, they developed eye diseases. It was after they were given real butter and whole milk that they had no eye problems.

  After Vitamin A was discovered, it took more than thirty years of experiments for scientists to be able to get a small amount of pure Vitamin A. Vitamin A is manufactured and is used successfully to treat a number of diseases. You can easily get enough Vitamin A by eating a variety of food. Good sources of Vitamin A are liver(肝脏) from some animals and dairy products such as milk and cream. Not only many vegetables contain carotene(胡萝卜素), from which your liver can make its own Vitamin A, some fruits also provide carotene which helps your liver to supply Vitamin A. As long as you are getting Vitamin A from food you won't need to take any extra in the form of liquid or pills.
