Active vitamin protects us against virus infections in a number of different ways. Vitamin D also controls the inflammatory processes and prevents them from becoming complicated. In a review article published in World Journal of Virology, scientists have pored over multiple meta-analyses and placebo-controlled studies that show a clear relation between vitamin D deficiency and an increased risk of respiratory viruses such as COVID-19 and influenza. Being vitamin D-deficient can also increase the risk of these infections turning into SARS (severe acute respiratory syndrome) that can result in potentially life-threatening circulatory failure and organ failure. Apparently, vitamin D plays an important and overlooked role in the prevention of virus infections.

Asthma is characterized by chronic inflammation and oxidative stress. Smoking, air pollution, heavy metals, and various environmental allergens also increase the risk. However, it appears that an optimal level of selenium and manganesein the blood can potentially improve health and survival in asthma patients. This is partly because selenium and manganese function as antioxidants that counteract oxidative stress and chronic inflammation. At the same time, selenium helps eliminate heavy metals, according to a study published in Scientific Reports.

- plus too much sugar

A growing number of children are affected by asthma, which is associated with a reduced quality of life. Diet plays a significant role in the development of the disease, and it appears that excessive sugar intake from breakfast cereals, soft drinks, candy, and other sources increases the risk. A deficiency in vitamin Dand magnesium, which is widespread, also raises the risk according to an article published in Frontiers in Nutrition. But why does sugar increase the risk of developing asthma, and how can vitamin D and magnesium help protect against the disease?

A chronic cough often follows in the wake of virus infections such as colds, influenza, and COVID-19. Lack of vitamin D seems to be a major contributor, coupled with the fact that a vitamin D deficiency often increases during the disease period. Vitamin D is of vital importance to a strong immune defense and also helps to regulate inflammation. Therefore, supplementation with vitamin D may be worth considering as a way of preventing virus infections and treating complications such as chronic cough, according to two studies that are published in European Respiratory Journal.

Diet, smoking, and aging processes increase the risk of developing chronic obstructive pulmonary disease (COPD), a condition that causes millions of deaths worldwide. According to a meta-analysis published in Nutrients, vitamin D supplementation seems to improve lung function.

Several studies have shown that optimizing your blood vitamin D levels with supplementation reduces the risk of contracting respiratory infections such as COVID-19. A new Hungarian study, published in Nutrients, has also found that very high doses of vitamin D given to hospitalized COVID-19 patients can reduce the risk of prolonged hospital stays and death due to severe complications.

Ageing, overweight, and respiratory infections can impair your sense of smell. However, a sufficiently high zinc intake from dietary sources or supplements can support or even improve the sense of smell – especially in older people and those who are overweight. This was shown in a study that is published in Rhinology. Unfortunately, zinc deficiencies are common due to poor diets and the use of various medical drugs that impair the body’s utilization of zinc.

Magnesium is vital for your health and quality of life in many ways. Still, around 30 percent of the population is believed to be magnesium deficient. This can either be because of an inadequate dietary intake of the mineral or because the body excretes too much magnesium due to stress, medication, chronic ailments, and other causes. Magnesium deficiency, which is difficult to diagnose, increases the risk of osteoporosis, infections, insomnia, cardiovascular diseases, overweight, diabetes, stroke, cancer, neurological disorders, and many other things, according to a review article published in Clinics and Practice. The authors list magnesium’s many functions and suggest supplementation as a convenient and inexpensive way to avoid a serious and widespread health problem.

Most chronic pulmonary diseases – including asthma, bronchitis, and COPD (Chronic Obstructive Pulmonary Disease) – are characterized by chronic inflammation that makes both the symptoms and the prognosis worse. Fish and fish oil supplements contain specific omega-3 fatty acids that appear to have an anti-inflammatory effect and may therefore be useful as both prevention and therapy for chronic pulmonary diseases. This was demonstrated in a large American population study that also included Europeans. What the researchers also mention is that people who fail to meet the official guidelines for fish consumption are often at increased risk of developing chronic lung diseases.

It is mainly older people and those with chronic illnesses that are vulnerable to COVID-19 and other respiratory infections. Also, it’s a fact that lack of essential nutrients impairs your immune defense and may have serious health consequences, whether you are vaccinated or not. A large study of 19 European countries reveals that low blood levels of vitamin D increases the risk of complicated COVID-19 infections, hospitalization, and death. According to the scientists, it is necessary to discuss and optimize people’s vitamin D status to help them resist future pandemics.

The body’s vitamin D status can be used to predict the risk of contracting COVID-19, developing serious symptoms in the acute disease phase, and dying of its complications. This was demonstrated in a large Chinese study, where majmost of the hospitalized COVID-19 patients lacked vitamin D.

Ever since the COVID-19 pandemic started, scientists have focused on vitamin D. This nutrient strengthens and regulates the immune defense in a number of different ways. Numerous studies have shown that lack of vitamin D increases the risk of being infected with COVID-19 and running into complications. High-dosed vitamin D supplementation of COVID-19 patients can lower their risk of being admitted to the intensive care unit and dying of the disease, according to a new meta-analysis that is published in Nutrients.

Many of us contract respiratory infections during the winter period. In many cases, the underlying cause is a deficiency of vitamin D, a key nutrient for immune health. Vitamin D also regulates the body’s inflammatory response, thereby preventing it from getting out of hand and becoming complicated or life-threatening. In a new review article, researchers looked at vitamin D’s role in preventing and fighting acute respiratory infections such as COVID-19 and influenza with particular focus on children and youngsters. The scientists point out that many people need to take higher doses of vitamin D to optimize levels of the nutrient in their blood.

A cold is a common and contagious virus that normally lasts around a week. If a person has poor resistance, however, complications such as sinus infections, ear infections, and pneumonia may follow. Colds cause a substantial number of sick days and represent a huge socioeconomic burden to society, but zinc supplementation seems to be able to reduce the number of sick days. Just remember to get enough vitamin D also because of interactions between the two nutrients.

Zinc has many different functions in the immune defense and a zinc deficiency increases the risk of infections and diarrhea, which are global causes of disease and mortality. According to a study published in Physiological Reports, being zinc-deficient can also lead to influenza complications such as bacterial pneumonia that is potentially lethal. The authors assume that zinc plays a key role in the body’s defense against respiratory infections, including COVID-19. They write that factors such as unhealthy diets, ageing, alcoholism, intestinal diseases, and various types of medicine can increase the body’s need for zinc.

The immune system is of vital importance to our ability to react to a COVID-19 infection. Most people don’t get any symptoms or only have mild ones, whereas the infection can become complicated and potentially life-threatening for certain exposed groups of people. Numerous studies have shown that our immune defense depends on different vitamins and minerals to function optimally. Now, a meta-analysis has shown that zinc supplementation can lower the mortality rate among COVID-19 patients. Many older people, chronically ill patients, and other vulnerable groups tend to lack zinc. This is a problem because the nutrient is not only essential for a well-functioning immune defense but also protects cells and tissues against damage caused by oxidative stress.
