- so make sure to get enough of the nutrient during the winter period

COVID-19 is highly unpredictable and be either totally harmless or life-threatening. Scientists from Oak Ridge National Laboratory in Tennessee recently made a comprehensive genetic analysis that reveals a new hypothesis – the bradykinin hypothesis – which shows why COVID-19 attacks the way it does, why symptoms vary, and why some groups of people are more vulnerable than others. The hypothesis also underpins the importance of getting enough vitamin D to prevent or possibly treat the disease. Vitamin D deficiency in the winter period is quite common and that may pave the road for new rounds of COVID-19 and an increased risk of complications.

- and throughout life

Vitamin D is important for a strong immune defense, healthy bones and cardiovascular system, cancer prevention, and for the support of many other essential body functions. However, it is not enough to follow the official guidelines for intake levels or to rely on blood tests. According to Carsten Carlberg, a professor at the University of Eastern Finland (UEF), the explanation lies in the fact that we humans respond widely different to vitamin D, so the optimal vitamin D dose varies from one individual to another. Based on years of research, Carsten Carlberg therefore advises all adults living at northern latitudes to take 100 micrograms of vitamin D daily throughout the winter period, just to be safe. Earlier studies indicate that the official recommendations for vitamin D are based on a miscalculation that has had fatal consequences for public health.

– including diabetic neuropathy

Neuropathic pain is caused by disease or damage in the somatosensory nervous system. According to a new review article that is published in the scientific journal Nutrients, it seems that therapy with vitamin B12 may have a positive effect on this type of pain. It also appears that vitamin B12 deficiency is rather common in people with diabetic neuropathy, which is a serious complication that may result in amputation in worst case. Therefore, it is vital that diabetics make sure to get enough vitamin B12. Patients with pain caused by peripheral neuropathy may also consider taking the other B vitamins and vitamin D.

Oily fish and fish oil contain the long-chained omega-3 fatty acids, EPA and DHA, that are of vital importance to the brain, the nervous system, and our mental health throughout life. Today, most people on a global scale lack these omega-3 fatty acids because of altered dietary habits, including the use of unnatural animal fodder. Low intake of omega-3 increases the risk of various ailments such as ADHD, autism, depression, borderline personality disorder (BPD), and bipolar disorder. Fish oil supplementation may therefore offer promise as prevention and part of the therapy used to treat a number of these disorders. The problem with modern diets is their disproportionate content of omega-6 at the expense of omega-3, an imbalance that may derail a number of physiological functions of importance to our mental health, according to a review article published in the science journal, Nutrients.

Life cannot exist without coenzyme Q10. The compound is necessary for the energy turnover in all our cells. It also functions as a powerful antioxidant that protects the heart and cardiovascular system against oxidative stress. Humans are able to synthesize Q10 but our endogenous production decreases with age. Heart failure patients also have reduced levels of Q10 which can be fatal, but decades of research have shown that Q10 supplements can improve quality of life and reduce mortality by close to 50 percent, according to a review article in Journal of Clinical Medicine. Here, the authors refer to 90 published articles. It is also important to get enough selenium, which helps Q10 function optimally.

Having sufficient vitamin D in your blood protects you against several cancer forms, according to a new review article that is published in Seminars in Cancer Biology. The summer sun is our primary source of the vitamin, but we can only store a limited amount in the liver for the winter period. The problem is made worse by the fact that we spend too much time indoors, and ageing even increases the risk of chronic vitamin D deficiency. The question is how much vitamin D do we need to protect us against cancer?
