Children who use non-traditional types of milk, and also have a reduced concentration of vitamin D compared to children who drink cow's milk, the researchers found. The results of the latest study were published in the journal CMAJ. Refusal of cow's milk lowers the level of vitamin D in deteyV recently significantly increased the popularity of non-traditional types of milk, for example, rice, almond, soy or goat, because of their desirable characteristics with respect to allergies and lactose tolerance. However, experts from St. Michael's Hospital in Toronto found that the consumption of non-traditional types of milk due to the decrease in the level of vitamin D in children. According to the National Institutes of Health, vitamin D supports bone strength by helping to absorb calcium from food and dietary supplements. People who have a deficiency of vitamin D, may in the future have a so-called softening of bones in children and osteomalacia in adults. In the latest study involved 2831 children aged one to six years, who consumed cow's milk or other milks. 85 % participants drank cow's milk, 12 % drank other types of milk and 3 % did not use milk at all. As a result, it was found that children who drank not cow's milk, were twice as likely to have the concentration of 25-hydroxyvitamin D below 50 nmol / L compared to children who ate a regular cow milk. "It is no secret that from cow's milk products must contain 40 IU of vitamin D per 100 ml, thus they are the main dietary source of the vitamin for children," - said Dr. Jonathon McGuire (Johnaton Macguaira), lead author of the work. It is known that Group D vitamins inhibit the growth of cancer cells, are responsible for normal growth and bone development, prevent the development of osteoporosis, rickets and arthritis, reduce the risk of atherosclerosis and diabetes. These diseases may be at an acute deficiency of vitamin D, and blurred vision occur in mild deficiency, loss of weight and appetite, insomnia appears. The best natural sources of vitamin D are considered fatty fish, beef liver, soy, cereals, eggs, margarine, mushrooms, orange juice. At the same time people who are regularly exposed to sunlight, does not need extra vitamin D sources as sunlight provides a synthesis of this vitamin in the skin.
