Corona Virus: How Important Is Vitamin D Use, What Are The Ump Hulu And Facts?


There is hardly any doubt that vitamin D plays an important role in the growth and health of our bones by combining and regulating calcium and phosphate, because of the damage caused by its deficiency. It is always encouraged to address this shortcoming.

And because of this, it is used more than you think. For example, according to a study, 20% of the population in the UK is severely deficient in vitamin D.

However, many experts say that healthy people do not need vitamin D supplements, in other words, they say that vitamin D in healthy people does not protect against any future disease, as some people think. Is.

So what is the truth?

Vitamin D helps relieve fatigue, regulates fatigue, and even cures cancer. But some medical professionals do not benefit from such extra vitamins as healthy ones.

Now people all over the world are asking to stay indoors because of the lockdown, many of us are paying full attention to the ingredients in our diet and want to know if they care about your health.

To find out what is true and what the trick is, BBC Future is republishing such reports with additional information from its archive.

Our colleagues at BBC Good Food have been researching various aspects of food ordering, tasty cooking in kitchens, and lock-down food.

Many of us are now confined to our homes due to social distance measurements during the lockout, so they are concerned about the lack of sunlight. And because of this, there is a risk of vitamin D deficiency. For many, the simplest solution is to start taking supplements (extra vitamins).

After all, these drugs are widely touted as unnatural foods. Vitamin D2 and D3 drugs are readily available without prescription from every drugstore, and their deficiency in the body is associated with immunity, fatigue, muscle, and osteoporosis. These vitamins are also known to cure cancer and prevent the effects of aging.

But the debate over whether vitamin D is required for all adults is highly controversial.

There is no doubt that vitamin D plays an important role in the development and health of our bones through the combination and regulation of calcium and phosphate. It is always encouraged to overcome this error.


And because of this, it is more used than you think. For example, according to one study, 20% of the UK population has severe vitamin D deficiency.

However, many experts believe that healthy people do not need vitamin D supplements, in other words, they feel that vitamin D in healthy people does not protect them from any future disease. Is.

Hit the top

Although vitamin D is a vitamin, it is not a vitamin.

It is actually a hormone that helps the human body to digest calcium. The real challenge is that there are no fish in the average diet except foods like vitamin D. But eyelet ultraviolet B rays in the sunlight can get vitamin D from cholesterol in the human body.

Vitamin D is found in the intestines like fish oil.

There are two types of vitamin D. The first is vitamin D3, which can be obtained from some other animals, including humans, and from the human body when exposed to radiation.

The second type of vitamin D is called D2, which is derived from vegetables such as mushrooms. Research shows that D3 is more effective, and according to a larger 2012 analysis, vitamin D3 is preferred to supplement.

Currently, the British Health Agency recommends that people use 10 micrograms of vitamin D in the winter and autumn, as sun rays create an angle to the area where these rays fall. UVBs cannot enter the Earth's atmosphere.

The Government Department recommends that people with vitamin D deficiency, including blacks, continue to take the supplement throughout the year.

Similar suggestions have been given in other countries.

In Canada, adults are advised to add 15 micrograms of vitamin D and two glasses of vitamin D milk or two glasses of soy milk to their daily diet. In addition, there is a law that cheese manufacturers must add vitamin D.

In the United States, adults are advised to add 15 micrograms of vitamin D to their diet, while in the United States, vitamin D should be added to industrial milk, breakfast cereals, cheese, yogurt, and orange juice. Also important.



Broken bones

But the importance of vitamin D does not mean that healthy people need vitamin D supplements at all times. Consider why you need these medications: developing bones and keeping them healthy.

The latest vitamin use guidelines have been developed based on research on elderly caregivers who are rarely prone to sunburn, which can lead to bone loss. Cracks occur and they develop osteoporosis (weak and complete osteoporosis). Tim Spector, a professor of genetic epidemiology at King's College London, says there may be shortcomings in research.

The main reason for taking supplements is to strengthen the bones but there is no clear evidence behind this idea.

According to an analysis published in 2018, increasing the amount of vitamin D in healthy people does not reduce the risk of bone fractures, and a total of 81 research reports suggest that increasing vitamin D supplements may or may not lead to bone loss.

Researchers suggest that these guidelines need to be revised in light of new research.

But Vitamin D helps people who can't get enough sunlight, said Sarah Leland, a senior nurse at the National Osteoporosis Society. According to the UK's National Institutes of Health, the NHS, in March and October, it is sufficient for people to sit in the sun and to get proper vitamin D without a screen.

"We know that people who take vitamin D supplements and calcium in the community cannot eliminate the risk of fractures," says Sarah Leland. However, people who cannot afford the right amount, i.e. those who do not move out of their homes or who live in nursing homes, may benefit from the supplement.

Researchers have yet to find clear evidence for this. An analysis of bone fracture prevention reviews in nursing homes and hospitalized communities suggests that vitamin D supplementation alone does not prevent fractures in the elderly.

Some evidence suggests that high doses of vitamin D may increase the risk of bone fractures. According to a randomized study, the risk of fractures and fractures in the elderly increased from 20% to 30% compared to those taking vitamin D supplements with higher doses.
 

There are also conflicting research reports on the effects of vitamin D on the prevention of aging and its association with other diseases.

One major argument is that vitamin D improves the body's immunity. Adrian Martino, professor of immune and respiratory infections at the London School of Medicine and Dentistry at Queen Mary University in London, who studies the effects of vitamin D on human health, says vitamin D can help fight respiratory infections. Available.

According to research, vitamin D can help prevent respiratory infections.


When their research team studied data from 11,000 patients in 25 clinics in 14 countries, they found that daily or weekly intake of vitamin D supplements reduced their risk of respiratory, asthma, or bronchitis infections. I had some benefits.

Although the study has been widely criticized, Professor Martineau says that risk reduction, albeit a minor one, is important and can be compared to other ways to prevent disease. Vitamin D supplements are given to 33 people to prevent the possibility of infection in the respiratory system, while 40 people are given the flu vaccine to prevent the flu in one person.

And now take old age. A study of the relationship between vitamin D and life expectancy has shown that vitamin D3 helps in the autoimmune system of proteins (homeostasis). Under this system, the proteins inside a cell automatically regulate its ability to maintain good cell health.

"We have found that maintaining adequate amounts of vitamin D3 in serum D3 protein improves homeostasis and slows the onset of signs of aging," the researchers said.

But other investigations have failed to reach a final decision.

Another analytical study concluded that more research is needed to determine the effects of vitamin D on mortality. A link between heart disease and vitamin D has been substantiated. This relationship means that the amount of vitamin D is reduced due to heart disease and not due to the lack of vitamin D causes heart disease.

Relationship?

This is the case with almost all research into low vitamin D levels.

Ian Reid, a professor of medicine at the University of Auckland in New Zealand, believes that diseases reduce the amount of vitamin D because being sick makes you less exposed to the sun, not sicker. There are.

"If you study a group of patients with a disease, you will find less vitamin D in them than in healthy people," he says. This leads to the conclusion that vitamin D deficiency causes diseases, but there is no evidence to prove it.

Some experts say that people who get sick have lower levels of vitamin D because they do not sit outside in the sun because of the disease, not because they get sick and because they have less vitamin D. ۔

When his research team studied data from 11,000 patients at 25 clinics in 14 countries, they found that taking vitamin D supplements daily or weekly reduced the risk of respiratory, asthma, or bronchitis infections. I've gotten something.

Although this study is widely criticized, Professor Martino, although small, is important in reducing risk and can be compared with other methods to prevent disease. To prevent the risk of infection in the respiratory system, 33 people were given vitamin D supplements, and 40 were given the flu vaccine in one person to prevent the flu.


Take old age now. A study of the link between vitamin D and life expectancy has shown that vitamin D3 helps the homeostasis of proteins. In this system, the protein inside the cell automatically regulates its ability to maintain good cell health.

"We found that maintaining adequate amounts of vitamin D3 in serum D3 protein improves homeostasis and reduces the onset of signs of aging," the researchers said.

But other research has failed to reach a conclusion.

Another analytical study concludes that more research is needed to determine the effects of vitamin D on mortality. The relationship between heart disease and vitamin D has been confirmed. This relationship means that the amount of vitamin D is reduced by heart disease, not by heart disease due to a lack of vitamin D.

With regard?

Almost all research on low vitamin D levels is the same.

Ian Reed, professor of medicine at the University of Auckland, New Zealand, believes that diseases reduce vitamin D levels because being sick makes you less exposed to the sun and less likely to be ill. There.

"If you study a group of patients with a disease, you will find less vitamin D than healthy people," he says. This leads to the conclusion that vitamin D deficiency causes diseases, but there is no evidence to prove it.

Some experts say that people who are sick have low vitamin D content, not because they are sitting outside in the sun, not because they are sick, and because they are low in vitamin D.

Sun rays serum

Although the research does not reach definitive conclusions, it does not diminish the importance of vitamin D. This may be one reason why they are doing poorly.

Some experts believe that vitamin D is best from sunlight, not a supplement. Some scientists say that vitamin D from direct sunlight is no better than vitamin D because vitamin D produced in the body is very beneficial for sunlight. The investigation has reached a final conclusion.

However, many experts agree that supplements are beneficial for those with low levels of vitamin D. Professor Martino states that people with low levels of vitamin D have benefited greatly from supplements to prevent lung and lung infections, but the effects are minimal, with moderate amounts.

Professor Reid says his research also shows the benefits of dietary supplements in people with low levels of vitamin D. However, more medications than the required vitamin D did not help.

But the problem is that it is very difficult to tell who is at risk for vitamin D deficiency. According to Robert Bank, a medical historian at the University of Warwick, a person who stores vitamin D for his needs during the winter. It does not depend on how long he has been in contact with the sun and how long he has been outside.

“The need for sunlight in the summer is determined by the individual nature of each person, which depends on the nature of their skin and the amount of fat in it,” she said. How quickly his body builds bones. This is a very complicated process. "

Therefore, you should not decide based on your symptoms of vitamin D deficiency, but rather test your blood with the help of your doctor.

Supplementary levels

Then there is the question of how many doses people need. Taking 25 D of Vitamin D per day is "no risk," says Professor Reid.

In the United States and Canada, 15 micrograms per day of vitamin D supplements is recommended, although some experts consider it to be inadequate.

But 62.5 micrograms of supplements are available at general pharmacy stores without a doctor's prescription, there is concern about their overuse, which in some cases can have adverse effects, including nausea. Can Some studies suggest that long-term use of vitamin D can lead to heart disease, but research is not conclusive?

But some experts say more vitamin D is needed.

In 2012, the UK's chief medical officer wrote a letter to general practitioners across the country asking them to give vitamin D to all at-risk patients.

He said a large portion of the population in the UK was deficient in vitamin D. In June 2018, researchers at the University of Birmingham wrote that a newborn's vitamin D deficiency can lead to death from heart failure and complications in two other children's diseases, due to vitamin D deficiency. There is a small appearance of a large number of people on the threshold of danger.

Soma, author of a Ph.D. dissertation at a university, says this type of vitamin D deficiency occurs because there is no system in place in the UK to monitor vitamin D supplements.

"In newborns, we say the decline was because they were not given supplements or supervised," she says. A newborn who is deprived of vitamin D for a long time develops a lack of calcium, which can lead to life-threatening complications such as heartburn or heart disease.

With so many conflicting findings, it is not surprising that medical experts are divided on the wide range of uses and benefits of supplements.

Some even say that the multi-billion dollar vitamin industry is promoting them more and more, while Professor Specter even calls this trend that they are 'so-called vitamins for so-called diseases'.

As the debate continues, the eyes of many experts are fixed on the Brigham and Women's Hospital, affiliated with Harvard Medical School, whose researchers are working on a long-awaited study called Vital. Assessing whether vitamin D and omega-3s have affected 25,000 people with cancer, heart attack, or various heart diseases.

It is hoped that the findings of this study, published later this year, will bring this debate to an end. Meanwhile, there is a widespread consensus among experts that the use of vitamin D supplements, especially in winter, is a waste of money in the worst-case scenario.

But 62.5 micrograms of prescription drugs are available in general pharmacy stores without a prescription, causing them to worry about their overuse and, in some cases, nausea. Some studies suggest that long-term use of vitamin D can lead to heart disease, but research is not conclusive.

But some experts say they need more vitamin D.

In 2012, the UK's chief medical officer wrote to general practitioners around the country asking them to give vitamin D to all at-risk patients.

He said most of the population in Britain had vitamin D deficiency. In June 2018, researchers at the University of Birmingham wrote that vitamin D deficiency in a newborn infant can lead to heart failure and death with complications, such as vitamin D deficiency. There are a large number of people at risk.

Ph.D. research writer Soma at a university says that this type of vitamin D deficiency is due to the lack of a system in the UK to monitor vitamin D supplements.

“In newborns, we are told that the decline is because they are not being supplemented or supervised,” she said. When a newborn is deprived of vitamin D for a long time, calcium deficiency can lead to life-threatening complications such as heartburn or heart disease.

With so many contradictory results, it is not surprising that medical professionals are divided on the benefits of a wide range of uses and supplements.

Some say that the multi-billion dollar vitamin industry is encouraging them more and more, Professor Specter also calls the trend the so-called 'vitamins' diseases.

As the debate continues, many experts focus on the Brigham and Women's Hospital affiliated with Harvard Medical School, whose researchers are working on a long-awaited study called Vital. Assessing whether Vitamin D and Omega-3 have affected 25 thousand people with cancer, heart attack, or various heart diseases.

The results of this study, published late this year, are expected to end this debate. Meanwhile, there is widespread agreement among experts that using vitamin D supplements is a waste of money, especially in the worst case scenario.
