Deficiency of this vitamin causes flu and colds

Why do some people keep catching cold? While winter comes and goes, some people never get a cold or flu? We know that some age groups are more susceptible to viral diseases than others; Like children, elderly and pregnant women. Also, medical center employees are constantly exposed to viral infections. But if you are not in any of these groups; So why do you keep catching cold? A very strong possibility is that you may be deficient in some vitamins. There is a direct connection between vitamin deficiency and colds.

What we read in this article

Vitamin D deficiency and increased risk of colds

The results of several studies show that vitamin D helps the body’s immune system in warding off respiratory diseases such as colds. Vitamin D plays its most important role in strengthening bones and increasing calcium absorption in the human body. But its significant role in improving the body’s immune system cannot be ignored.

Unfortunately, vitamin D is naturally present in few foods. The best way to supply vitamin D to the body is to be exposed to sunlight. But are you exposing yourself to enough sunlight during the hours when sunlight is the most radiant and warm? Statistics show that about 80 to 90 percent of people in our country suffer from vitamin D deficiency. So it is not at all unlikely that your frequent colds are also rooted in vitamin D3 deficiency. Do you use vitamin D tablets?

The effect of vitamin B12 deficiency on colds

We said that there is a direct connection between vitamin deficiency and colds. Anyone who does not have a healthy diet may be deficient in vitamin B12. Vitamin B12 helps your body make DNA, the basic building block of cells. The human body is unable to make vitamin B12. This vitamin should be supplied to the body through the consumption of meat, dairy products and food such as eggs.

People who have absorption problems in their digestive system are more at risk of vitamin B12 deficiency than others. In the digestive system, there are cells that absorb vitamins. If your body has antibodies against these cells due to some diseases and damages them, then the possibility of vitamin B12 deficiency is very high. Inflammation of the stomach lining and lack of hydrochloric acid in the stomach, which is needed to absorb vitamin B12, can reduce the level of this vitamin in the body.

It is interesting to know that many people who have undergone gastric bypass surgery have difficulty absorbing vitamin B12. There is also a rare medical condition in which the stomach is unable to make an important protein called intrinsic factor. In this case, the body is disturbed in the absorption of vitamin B12, and low levels of this vitamin lead to a type of dangerous anemia. When you are deficient in vitamin B12, the body’s immune system is not able to perform its proper function, and as a result, your chances of catching colds, flu and other viral diseases such as corona will increase.

Iron deficiency and colds

Iron deficiency anemia makes you more vulnerable to diseases. Many people do not take their mild anemia seriously and say the number hemoglobin They have been around 10g/dL for years and nothing bad has happened to them. Also, some other people have thalassemia minor and they don’t even know about it.

Apart from the iron mineral, vitamin B9 or folic acid also plays a role in causing anemia and helps in the formation of red blood cells. Folic acid tablets are often prescribed for patients with thalassemia minor. Also, if anemia is related to iron deficiency, iron tablets should be used. Lack of folic acid and iron leads to anemia and the weakness of the immune system and frequent colds.
