Our body needs vitamin D. The problem is that it is synthesized under the influence of ultraviolet light, and in winter there is not enough sunlight in northern latitudes. In addition, over the years, the ability to synthesize vitamin D decreases, informs Ukr.Media.
Therefore, it is necessary to introduce products into the diet that make up for the lack of this most important trace element. According to experts, fish will be an excellent source of vitamin D. The most of it is contained in wild salmon, while in farmed salmon, the concentration of the useful substance is much lower. Herring, fish oil, canned tuna and sardines are also rich in vitamin D.
Do not give up butter, sour cream and cheese. But keep in mind that, unlike fish, vitamin D is much less in dairy products, so eating only butter or cheese will not be able to replenish the daily norm. It will be useful to introduce beef liver and egg yolks into the diet.
Vitamin D affects muscle tone and immunity, growth and development of bones, it is used as a prevention of rickets and osteoporosis. Normal functioning of the thyroid gland, blood pressure and blood clotting also depend on it.
Most often, the lack of an important vitamin is observed in the elderly and in children who grow intensively and need "fuel" for the development of the body. There is little of this trace element in polluted regions, where the sky is often overcast with smog. Also at risk are pregnant and lactating women, vegetarians and followers of diets in which the content of any fats is minimized.
