The ABCs of vitamins:

  • Sources. Contained in egg yolks, liver, fish and animals, butter, eggs. Small amounts of vitamin D are found in fungi and some higher plants. It is produced by exposure to sunlight in the body.
    The consequences of the shortage. Lack of vitamin D causes disease in children, which is called rickets. Rickets affects children living in areas where there is little sunshine. The age at which children are most susceptible to rickets – from three months to two years. To prevent the disease rickets child should be provided with adequate food.

  • An illustration of the fact how important vitamin D is to the body, can serve as a case described in one of the books of the famous zoologist and writer Gerald Durrell. His zoo monkey paralysis ill and died. The vet suggested that the disease is caused by a lack of phosphorus in the body. However, the animals received a sufficient amount of phosphorus with feed. Guessing that the body of monkeys for some reason, does not assimilate phosphorus, the doctor suggested to make sick animals injections of vitamin D3. And a miracle happened! Soon it began to improve, and in a month the monkeys have fully recovered.
