The corona crisis has shed new light on the importance of having a strong immune defense, one that protects us against virus infections in the long run. Selenium plays a vital role for a number of different reasons but, unfortunately, there is widespread deficiency which increases the risk of infections and related complications. In a new review article that is published in International Journal of Molecular Sciences, the authors look closer at selenium’s role in connection with different types of virus infections such as influenza, HIV, and hepatitis with particular focus on COVID-19. The purpose of their article is to inform about new nutritional strategies that may contribute to a strong and well-functioning immune defense – mainly when it comes to COVID-19 and virus types that tend to mutate all the time.
Q10 is a unique and wonderful coenzyme with a key function in energy turnover and a role as a powerful antioxidant. The body produces the lion’s share Q10 for its own needs but the endogenous synthesis of the compound decreases with age. Moreover, cholesterol-lowering statins and bisphosphonates used to treat osteoporosis disrupt the body’s Q10 synthesis. Over the past decades, numerous studies have shown that Q10 supplementation can slow down the ageing process. Q10 is also useful in connection with heart failure and several other chronic ailments that typically occur in old age. This is described in a review article that is published in Mechanisms of Ageing and Development. With Q10 supplements, it’s important to choose pharmaceutical-grade products with documented quality and bioavailability.
A well-functioning memory is vital for our quality of life. With the increasing number of seniors, however, the dementia rate is on an incline. According to a study that is published in Clinical Nutrition, it looks as if a combination of fish oil and antioxidants such as lutein and zeaxanthin may improve memory in elderly seniors. You can support your brain and memory on a daily basis by eating oily fish or fish oil supplements together with antioxidants from foods such as cabbage, spinach and other leafy greens, and eggs. Another important antioxidant is mezo-zeaxanthin that is found in certain fish and in fish skin.
It is estimated that one billion people worldwide lack selenium. This has fatal consequences for public health because it increases the risk of virus infections, thyroid disorders, cardiovascular diseases, cancer, neurological disorders, and involuntary infertility. Adding to that problem is the fact that mercury, a known environmental toxin, throws a wrench into selenium’s different functions. In the following, we have compiled a long list of studies that look closer at the consequences of selenium deficiency and the advantage of optimizing the body’s selenium status with help from supplements.
Nasal polyps are local growths that may cause runny nose, breathing difficulty, reduced sense of smell, and other symptoms. The polyps are a result of chronic inflammation that can have its roots in a number of causes. According to a new study that is published in Clinical Epidemiology and Global Health, patients with nasal polyps have lower levels of zinc in the affected tissue. Zinc is important for our immune system and for regulating inflammatory processes. Therefore, the nutrient may even have therapeutic potential because many people have relapses after their treatment. Earlier studies even suggest that patients with nasal polyps lack selenium, which is why one should also pay attention to underlying causes like respiratory allergies and food intolerance.
The winter period is the time of year where we typically lack vitamin D, and this contributes to new waves of COVID-19 and other virus infections. Moreover, many older people, dark-skinned individuals, nursing home residents, and diabetics often suffer from chronic vitamin D deficiency which makes them much more vulnerable. Since the springe of 2020, numerous studies have demonstrated that lack of vitamin D increases the risk of COVID-19 infections, acute respiratory distress syndrome (ARDS), intensive care admission, and death. This is described in a new meta-analysis that is published in Frontiers in Public Health. Danish threshold levels for vitamin D in the blood are also too low, apparently. The question is: How much vitamin D do we really need?
