The Significance of Vitamin D
Vitamin D is an essential fat-soluble vitamin which performs like a hormone in regulating the bone formation and the absorption of calcium and phosphorus from the intestine. It has its vital role in controlling the movement of calcium between bone and blood, and vice versa. Deficiency of Vitamin D in infancy and childhood can cause the deformed bones characteristic of rickets. Its deficiency in adults causes a softening of the bones known as osteomalacia. Usually it is seen that people of northern countries or people who covered the body with clothes because of tradition dictates, are likely to have Vitamin deficiency. On the other hand, an excess of the vitamin can also cause loss of appetite, weight loss, nausea, headache, depression and deposits of calcium in the kidneys.
Cod liver is rich in Vitamin D dietary. Egg yolks and butter are also rich in such vitamins. However, besides consuming food, the maximum amount of vitamin D in the body is formed during a chemical reaction, and it starts when the skin gets exposed to the sunlight. Modern researches have proved that the nominal levels of vitamin D in patients with autoimmune disease may even make the condition of the patient worse.
A disease of bone-thinning disorders called Osteomalacia, occurs exclusively in adults due to the deficiency of Vitamin D. This disease can be treated with vitamin D and sometimes a subtle combination of calcium supplements to it. This can occur exclusively in adults or people of almost all ages. Vitamin D deficiency occurs mostly in winter because of insufficient sunlight exposure during that season. Additionally, the place where the atmospheric pollution is high and the sun’s ultraviolet rays are obstructed one might have the risk of deficiency of vitamin D.
Vitamin D deficiency is commonly found in strict vegetarians, dark-skinned people, and those people with liver or kidney disease. It is also common in people suffering from intestinal malabsorption which is caused due to some prior intestinal surgeries, or from celiac disease.
Short of Vitamin D in the body can lead to cause several chronic diseases such as high blood pressure, tuberculosis, cancer, periodontal disease, multiple sclerosis, chronic pain, seasonal affective disorder, peripheral artery disease, cognitive impairment which causes memory loss and hazy brain functioning. Children with Vitamin D deficiency suffer from disease called rickets which is characterized by impeded growth, and deformity, of the long bones. People ailing from hyperparathyroidism also have the tendency of Vitamin D deficiency. This is the condition in which the parathyroid gland is overactive. People with advanced prostrate cancer also suffer from the deficiency of Vitamin D.
The strict vegans are lacking in Vitamin D, they should obtain adequate vitamin D. It is essential to include vitamins in their diet during the winter which can be ensured by consuming fortified products or supplements. The breast feeding vegan women of the northern latitudes are seen to be victim of such deficiency and so they should ensure of their vitamin intake during winter by using fortified foods or by taking supplements. Eventually, it is recommended that parents should take in vitamin D fortified foods or supplements to the diet of their infants during the winter months, particularly if they are having dark complexion.
