[New Tang Dynasty News February 24, 2021, Beijing time]The study found thatcoronavirus diseaseDuring the epidemic, people who lack vitamin D in their bodies are more likely to be infected. But now most people have the problem of vitamin D deficiency, how to effectively supplement it?
Increase the first lineImmunityVitamin D can be loweredNew coronal diseaseRisk of infection
Vitamin D is the “sunshine vitamin”. When the sun shines on the skin, the human body can naturally synthesize bioactive vitamin D. However, most modern people stay indoors and are used to applying sunscreen when they go out. In winter, they cover their bodies tightly with clothes to block the skin from receiving ultraviolet rays from the sun, leading to a general lack of vitamin D.
But vitamin D plays an important role in human health. Yang Jingduan, director of the Young’s Center for Integrative Medicine in the United States, said that it not only helps maintain bone health, but is also an important human hormone that affects all aspects of the body’s function. Taking vitamin D can also increase serotonin in the body to improve mood and mental stress. “In summer, the content of serotonin in the body is the highest, which is related to the sun’s exposure,” he said.
When the human body lacks vitamin D, it is easy to suffer from osteoporosis, rickets, heart disease, diabetes, depression, Alzheimer’s, cancer and other diseases.
Existing research has found that vitamin D andcoronavirus diseaseRelated to the infection. The Journal of the American Medical Association and the Journal of the European Biochemical Association previously published separate studies. According to the results of the two studies, the risk of vitamin D deficiency in patients with new coronary pneumonia can increase to 50% to 77%. A hospitalized blood sampling survey of patients with new coronary pneumonia shows that if they are severely deficient in vitamin D, the chances of developing severe illness in the future are much higher.
Nevertheless, Chen Weihua, PhD in Neurology at Oxford University and Dean of Aijia Nature Clinic, pointed out that although there is no definite data to prove that vitamin D supplementation can prevent new coronary pneumonia.But vitamin D can indeed increase the body’s first lineImmunity. Studies have found that if there is a severe lack of vitamin D in the blood, the chance of contracting influenza will increase by two times. In 2018, a study indicated that vitamin D supplementation can reduce the risk of respiratory virus infection by 70%.
3 ways to supplement vitamin D
Vitamin D is a sunshine vitamin and can be supplemented from three channels: sun exposure, food intake, and supplements.
1. Bask in the sun: 15 minutes a day in the sun, if you have time to bask on holidays, at least half an hour. Yang Jingduan pointed out that the best sun exposure at noon, when the ultraviolet rays are particularly strong, can stimulate the skin to produce enough vitamin D in a short time.
When you are in the sun, you should not wear sunscreen, and at least one-third of your skin is exposed to the sun. And to dry outdoors, not indoors through glass. The head and face can be protected by a hat, because the skin on the head and face is inherently less.
2. From food intake: dried mushrooms, algae, eggs, liver, caviar, oats, milk, yogurt, all contain vitamin D; you can also eat some fatty fish, such as herring, or sardines, tuna , They not only contain vitamin D, but also essential fatty acids omega-3. However, the amount of vitamin D in food is generally small.
3. Taking supplements: The original recommended daily intake of vitamin D for adults was 400-800IU, but it can be increased to 1000IU during the epidemic. Vitamin D is fat-soluble. It cannot be excreted from the body by taking too much water-soluble vitamins. It cannot exceed 2000IU a day, otherwise it may cause side effects.
TakeD3The fastest supplement experts share tips for choosing supplements
If you want to supplement vitamin D, sun exposure is best, and food supplements are also acceptable, but taking supplements is more efficient.Chen Weihua pointed out that taking vitaminsD3It is the fastest way to make up D.
Vitamin D is divided into vitaminsD2There are two kinds of vitamin D3, and there are different types of supplements accordingly:
When choosing vitamin D supplements, the priority order is: inactive vitamin D3>active vitamin D3>vitamin D2.
Chen Weihua explained that both vitamin D2 and vitamin D3 can produce active vitamin D through body metabolism, and both are effective. However, the amount of vitamin D3 converted into active vitamin D is more than that of vitamin D2, and its bioavailability is higher than that of vitamin D2, which can improve the concentration of serum vitamin D.
Active vitamin D3 works immediately after eating it. Inactive vitamin D means that the body can convert it into active vitamin D as needed. Therefore, supplementing with inactive vitamin D3 can avoid accidental over-intake and is safer for consumption.
On the supplement package, active vitamin D3 is indicated in milligrams, and inactive vitamin D3 is indicated in IU. Since vitamin D3 is mostly derived from animals, vegetarians can choose inactive vitamin D3 from algae or moss when purchasing.
The dosage form can be liquid or solid, but the absorption rate of liquid vitamins is faster than capsules and tablets. Vegetarians prefer to choose liquid, because the capsule shell also contains animal ingredients.
Regardless of the dosage form, it is better to add unsaturated fatty acids, such as olive oil. Chen Weihua reminded not to use coconut oil with saturated fatty acids and avoid soybean oil. Studies have found that soybean oil affects the performance of hypothalamic genes in the brain.
In a chaotic world, if you have a healthy way, look at health 1+1!
