But residents of the northern regions do not have enough sunlight, so for them the dosage is increased to the maximum. Also, an increased dosage is recommended for obesity, bedridden patients living in areas with poor ecology, who often work night shifts, people with diseases of the gallbladder, liver and intestines.<\/p>\n\n\n\n
Formula-fed children should not be given additional calciferol. In the mixture, it is already added in the right amount for the normal growth and development of the child. In adolescence and pregnant women, it is recommended to supplement the diet with fish oil, dairy products and animal origin.<\/p>\n\n\n\n
Deficiency of calciferol can provoke the development of serious diseases or malfunctions. Vitamin D deficiency can be caused by sunscreens and sprays that protect the skin from ultraviolet radiation, or bad habits (smoking, excessive alcohol consumption). Hypovitaminosis occurs mainly from November to March, when solar activity is low.<\/p>\n\n\n\n
People with dark skin are at risk for vitamin D deficiency. Melanin protects it from ultraviolet radiation and prevents the natural production of calciferol. After 60 years, the intestine absorbs fat worse and this worsens the absorption of the vitamin.<\/p>\n\n\n\n
With obesity, calciferol dissolves in tissues, not having time to participate in biochemical processes. Vegetarians do not eat animal products, which are the highest concentrations of vitamin D.<\/p>\n\n\n\n <\/figure>\n\n\n\nAge<\/td> Vitamin D deficiency symptoms<\/td><\/tr> Children<\/td> Calciferol is necessary for the normal formation and development of the fetus, innate immunity. Therefore, it is included in infant formulas. It is necessary for the formation of the skeleton, muscles, nails, teeth. Vitamin D deficiency is indicated by:slow tightening of the fontanel;growth retardation;sudden weight loss;excessive excitability, tearfulness;strong sweating;sleep disturbance.Also, the symptomatology is manifested in a change in the bone skeleton – a disproportionately large head, a flat nape, crooked legs, a convex forehead. Children are often diagnosed with rickets.<\/td><\/tr> adults<\/td> Vitamin deficiency is determined using laboratory tests. The symptoms of a lack of calciferol are:sleep disturbance;frequent infectious diseases of the respiratory tract;chronic fatigue;caries;nervousness, irritability;obesity;pulling and aching pains in muscles, joints, bones;constipation or diarrhea;alopecia;blurred vision;fragility of bones, frequent injuries, fractures;muscle cramps;decreased appetite, up to anorexia;peeling and dry skin.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\nSince most symptoms accompany many health problems and diseases, focusing only on them is not a diagnosis. But this is a reason to see a doctor to check the level of vitamin D. The norm is 30-100 ng \/ ml, a slight deficiency is less than 20-30 ng \/ ml, a value of less than 10 ng \/ ml indicates a deficiency.<\/p>\n\n\n\n
An excess of the vitamin (hypervitaminosis) in countries where there is little solar activity is rarely diagnosed. But the cause can be excessive consumption of animal food. With an excess of vitamin, its indicator increases to 100 ng \/ ml and above.<\/p>\n\n\n\n
Then calcium salts begin to be deposited on the internal organs, muscles and skin, which impairs the functioning of the body and provokes health problems. The most common options are stone formation, kidney failure, and visual impairment. Symptoms of excess calciferol:<\/p>\n\n\n\n
irritability;<\/li> insomnia;<\/li> muscle cramps;<\/li> vomit;<\/li> the appearance of a rash;<\/li> stool disorder (diarrhea);<\/li> frequent urination.<\/li><\/ul>\n\n\n\nAlso, an excess of vitamin D increases the severity of disease symptoms. Reactions similar to allergic manifestations may occur.<\/p>\n\n\n\n <\/figure>\n\n\n\n<\/span>Seafood rich in vitamin D<\/span><\/h2>\n\n\n\nThe main category of foods containing vitamin D is seafood. Fatty fish are the best – 100 g of canned salmon will provide an adult with a daily dose of calciferol. Its highest content is in fish oil, which is enough to add to food in a small amount to eliminate the deficiency of calciferol.<\/p>\n\n\n\n
According to the data, in wild fish it is contained in a higher concentration than in those that live in artificial reservoirs. The temperature of the water also affects its quantity. It is recommended to choose fish that live in cold waters. It contains five times more calciferol than warm water. Which foods have the most vitamin D (per 100 g, in IU):<\/p>\n\n\n\n
cod liver – 4000;<\/li> salmon: wild – 1000, from cages – 600;<\/li> mackerel and snapper (or reef perch) – 400;<\/li> Atlantic herring – 310;<\/li> sardine in canned food – 270-300;<\/li> mackerel – 250;<\/li> tuna – from 120-236;<\/li> caviar (black, red) – 230;<\/li> halibut and shrimp – from 150;<\/li> oysters – 70.<\/li><\/ul>\n\n\n\nWhat other fish have vitamin D – pink salmon, salmon, trout, chum salmon, eel. But its greatest content is in cod liver, from which oil is made, packed in capsules. In addition to calciferol, they additionally contain retinol and fatty acids.<\/p>\n\n\n\n
<\/p>\n\n\n\n
<\/span>Meat and eggs<\/span><\/h2>\n\n\n\nMeat also contains calciferol, but in a small amount. To meet the daily requirement of vitamin D, you can choose from only two foods. In 100 g of beef liver – 50 IU of calciferol, in pork – up to 60 IU. It is also found in small amounts in chicken egg yolks. A pair of eggs contains 80-90 IU of vitamin D, while quail eggs contain 2 times less.<\/p>\n\n\n\n
<\/span>Dairy<\/span><\/h2>\n\n\n\nCalciferol is present in dairy products. But you need to choose them with a high fat content, otherwise it leads to a loss of the vitamin. It is bad if calciferol is added to them additionally, then it is poorly absorbed. One glass of milk (from 2.5%) fills 20% of the daily requirement for it. Hard cheese, natural yogurt, cottage cheese, sour cream and butter also help to eliminate the deficiency.<\/p>\n\n\n\n <\/figure>\n\n\n\n<\/span>Plant sources of vitamin D<\/span><\/h2>\n\n\n\nThere is little calciferol in plant products. This option is more suitable for vegetarians. The plant foods with the highest concentrations of vitamin D are wild mushrooms, which get enough sunlight.<\/p>\n\n\n\n
Although champignons are grown on purpose, they are illuminated with quartz lamps 3-4 hours before harvesting. Up to this point, they contain 30-40 IU of calciferol, after treatment, its concentration increases to 400 IU. A lot of vitamin D in 100 g of mushrooms:<\/p>\n\n\n\n
vulture – 2500;<\/li> chanterelles – 340;<\/li> morels – 250;<\/li> oyster mushrooms – 110;<\/li> shiitake – 50-100 IU.<\/li><\/ul>\n\n\n\nIn grains, nuts, vitamin D – a small amount. In 100 g of corn oil, it is only 7-9 IU. But in cereals and baby food, the level of calciferol is higher, it is enough to prevent deficiency. Manufacturers add the necessary vitamins and minerals to them. Therefore, a serving of oatmeal contains up to 160 IU of calciferol.<\/p>\n\n\n\n
Vitamin D is also found in dark green vegetables – squash, cabbage, zucchini, spinach. From fruits, store-bought juices will be useful, in which vitamins and nutrients are additionally added. Orange juice would be ideal.<\/p>\n\n\n\n
