It is already known that severely affected corona patients often lack vitamin D and selenium, both of which are nutrients that are important for the immune system. A team of Danish scientists has now confirmed a Dutch study showing that lack of vitamin K is also widespread among patients with severe cases of the coronavirus. Vitamin K is mainly found in dark, leafy greens. In the body, the nutrient occurs as vitamin K1 and vitamin K2 and they have different functions. Lack of vitamin K or poor utilization of the nutrient may be a result of a poor diet or using certain types of medicine. Although there is no evidence that vitamin K can prevent or mitigate corona infections, the scientists present several interesting hypotheses.

Heart failure affects millions of people worldwide and many die within the first year of being hospitalized with acute heart failure. However, eating a diet that is rich in the omega-3 fatty acid EPA from oily fish and ALA from plant foods such as walnuts is linked to a lower risk of blood clots and early death, according to a new study that is published in Journal of the American College of Cardiology. You can also read more about another compound that improves cardiac function and survival after acute heart failure.

Loss of muscle mass may be a result of a number of factors such as lack of exercise, too little protein, and ageing. Insulin resistance and acid accumulation are also related to loss of muscle mass, and it looks as if increased intake of vegetables with potassium, a base-forming mineral, is linked to decreased loss of muscle mass in men – but not in women.

- an overlooked connection

When it comes to battling COVID-19, the main focus is on hygiene, face masks, lockdown, and delayed vaccines. For several months, scientists have urged people to take vitamin D supplements during the winter period as a way of preventing new waves of COVID-19. This is because vitamin D is of vital importance for a well-functioning immune system and it is known that deficiencies of this nutrient contribute to the spread of seasonal virus infections. We also see that groups of people that are most likely to be vitamin D-deficient – including seniors, nursing home residents, people with dark skin, overweight individuals, diabetics, and those with chronic diseases – are most vulnerable towards COVID-19. The British government is already handing out vitamin D supplements to exposed groups, according to an article in Daily Mail and a review article that is published in British Medical Journal. But why is vitamin D so important for the immune defense, why are some people more likely to become deficient, and how much vitamin D do we actually need? Also, will vaccines cut the mustard if COVID-19 mutates?

- together with two other nutrients

Migraine is a chronic neurological disorder that can ruin your quality of life and cost you many sick days. Migraine medicine does not necessarily work for all patients and many people get side effects. Therefore, prevention is a better strategy. According to a new study published in Nutrition Journal, zinc supplements have the potential to significantly reduce the frequency of migraine headaches. You can also read about two other nutrients that reduce the frequency and severity of migraine attacks and what it is that triggers them. The most important thing is to find and address the different causes. Diet and lifestyle have a profound impact.

Vitamin D plays an overlooked role in the immune defense. Being deficient of the nutrient increases your risk of bacterial pneumonia by up to 60 percent, according to a large Danish study of 116,000 participants that was carried out by scientists from Herlev Hospital, Gentofte Hospital, and the University of Copenhagen.
Because many older people, cancer patients, and other chronically ill individuals are at increased risk of respiratory infections and because bacterial pneumonia can be potentially lethal, the scientists see a huge potential in using vitamin D supplements to prevent the disease.
