What are the causes of vitamin D deficiency?

Vitamin D is an important part of any diet because it helps to strengthen bones by helping the body in calcium absorption. Thus, the lack of this vitamin is harmful, but fortunately the causes can usually be determined to be treated. One of the most common causes of vitamin D deficiency is the lack of exposure to sunlight because the sun promotes the body to create this nutrient. Some diseases that deal with the digestive tract can also lead to the body's inability to properly absorb this vitamin. Of course, for a long time you simply do not consume this vitamin for insufficient offer, such as vegetarians and vegans who do not replace animal products with vitamin supplements.

It may seem surprising that the sun can help the body to create a nutrient, but the fact is that avoiding the sun is one of the main causes of vitamin D deficiency. For this reason, people who constantly wear clothes that cover their levels ntire live far from the equator, or rarelyAnd they go out during the day, this important vitamin is probably missing. Another related risk is to have dark skin, because a large amount of melanin can reduce the reaction of the skin to sunlight, resulting in the body to cause less vitamin D in the sun.

Anyone who avoids animal products for a long time, such as vegetarians and vegans, should add vitamin D supplement to its diet because it is particularly at risk of lack of this nutrient. Cheese, egg yolk, fish, fish oil and liver are some of the foods with a large amount of vitamin D and avoiding these products is one of the causes of vitamin D deficiency because it is difficult to obtain enough of this vitamin. Of course, fruits and vegetables also contain vitamin D, but few vegetarians and vegans eat enough of these foods to replace the lack of the animal products in the diet.

Some people get a lot of sunThey eat a lot of food full of vitamin D, but still have a shortage. This is because the causes of vitamin D deficiency include certain conditions that reduce the body's ability to properly absorb this nutrient. Celiac disease, Crohn's disease, cystic fibrosis and colitis are known for not allowing the body to properly absorb this and other vitamins. In addition, the kidneys that do not work at their best, perhaps because of old age, also slow down the absorption of vitamin D, which means that age is also one of the many causes of vitamin D deficiency.
