[이데일리 이순용 기자]In addition to Corona 19, a method to increase vitamin D levels, which helps prevent infectious diseases by raising immunity during the cold and flu season, was introduced. Getting enough vitamin D for the cold and flu season can be difficult if you live in a place with less sunlight in winter.
According to the Korea Food Communication Forum (KOFRUM) on the 18th,’Verywell Health’, a website specializing in health in the United States, announced’How To Boost Your Vitamin D Levels During the Cold and Flu Season’. Cold and Flu Season), the 11th article selected and announced 11 vitamin D supplements that help prevent respiratory diseases such as Corona 19, flu, and cold.
Vitamin D contains’vitamin’ in its name, but strictly speaking, it is a hormone. Unlike other major nutrients, your body can make vitamin D directly. When your skin is exposed to the sun for a long time, your body synthesizes vitamin D.
In a study of more than 14,000 people, people with low levels of vitamin D in the blood had a 58% higher risk of developing acute respiratory disease than people with high levels of vitamin D. A recent study found that people with vitamin D deficiency are more susceptible to the deadly’cytokine storm’ of Corona 19. Research papers have also published that vitamin D deficiency is associated with the severity of Corona 19. Vitamin D deficiency is also associated with an increased risk of depression, fractures and fatigue.
Eight foods that supply vitamin D selected by’Berrywell Health’ include eggs, salmon and tuna. Eggs are rich in vitamin D in their yolks. More vitamin D is in eggs laid by hens raised in the yard and given plenty of sunlight. Studies have shown that the vitamin D3 content of egg yolks raised outdoors was 3 to 4 times higher than that of hens raised indoors.
Oily fish such as salmon contain vitamin D as well as omega-3 fats such as DHA. Canned tuna is also a food that can easily consume vitamin D. Milk, which is known as the’king of calcium’, also contains vitamin D, vitamin A, and protein. Beef liver is also an excellent food source of vitamin D, folic acid (a type of vitamin B group) and protein. Among plant foods, mushrooms are rich in vitamin D. Mushrooms, when exposed to the sun’s ultraviolet rays, contain vitamin D.
There is also a way to supplement vitamin D by ingesting fortified (added) orange juice and cereal.
