It is said that it is important to enhance immunity to prevent COVID-19 infections.
We would like to survive this “with corona” era in a healthy way with improving immunity, and maintaining a healthy body both physically and mentally.
Based on avoiding “Three Cs” such as Closed spaces, Crowded places and Close-contact setting, what we can do now is to enforce “hand washing” and “immune system improvement”.
This time, I would like to introduce Vitamin D, which is said to boost your immune system.
What is immunity?
Immunity is a mechanism that protects the body from harmful substances such as bacteria and viruses that have entered the body. It is the immune system that eliminates viruses into the body and prevents them from getting sick. People with low immunity are less susceptible to the virus, so they are more susceptible to various diseases as well as infectious diseases. On the other hand, people with high immunity have a high resistance to viruses, so they are less likely to get sick and can stay healthy.
How does vitamin D work?
Vitamin D has the function of supporting calcium balance and maintaining bone health. In addition, some research shows that having healthy levels of vitamin D can help keep your immune system healthy and may protect against respiratory illnesses in general.
Vitamin D is necessary for the proper functioning of your immune system, which is your body’s first line of defense against infection and disease.
For example, low vitamin D levels are associated with an increased risk of respiratory diseases, including tuberculosis, asthma, and chronic obstructive pulmonary disease, as well as viral and bacterial respiratory infections.
How to take vitamin D efficiently?
Normally, vitamins cannot be produced inside body, so it is necessary to take them from foods, etc. However, vitamin D has the characteristic that 80 to 90% can be produced in the body not only by diet but also by exposure to sunlight.
Therefore, it is recommended to make a habit of going out, such as walking for 20 to 30 minutes a day.
【Foods high in vitamin D】
・Mushrooms
・Salmon, Tuna, mackerel, Sardines
・Egg yolks etc.
Since seafood, especially fish skin, contains a lot of vitamin D, eat it without leaving. Vitamin D is resistant to heat, so it can be cooked, boiled, or fried in a variety of ways.
It is recommended to eat foods high in vitamin D for vitamin D intake, but it is important to sunbathe for a certain period of time a day. No matter how much vitamin D you take from food, you can’t get activated vitamin D unless you get it in the sun.
