The most common inflammatory bowel diseases are Crohn’s disease and ulcerative colitis. Lack of certain nutrients can contribute to the development of these conditions. On the other hand, the diseases and the therapies used to treat them may also impair the body’s ability to absorb or utilize certain nutrients, thereby starting a vicious cycle that can make the disease worse. This was demonstrated in a new Greek study that is published in Nutrients. Chronic inflammatory bowel diseases primarily occur in the Western countries and especially at northern latitudes, which suggests that sun exposure and typically Western diets pay a major role in the development of these diseases.
The British government has decided to hand out free vitamin D supplements to exposed groups to help fight COVID-19
An abundance of international science links widespread vitamin D deficiency to impaired immune defense, a problem that has contributed to new COVID-19 waves and tends to make the infections life-threatening. The British government has therefore decided to give free vitamin D supplements to 2.2 million seniors, nursing home residents, chronically ill, and other vulnerable people to help combat COVID-19. The whole purpose of this is to slow down the epidemic and put an end to the numerous shutdowns of society, according to an article in the Daily Mail.

Older people can easily become deficient of vitamins and minerals, which can weaken their immune system and make them more prone to infections and prolonged periods with disease. On the other hand, older people who take a multivitamin and mineral supplement with zinc and large quantities of vitamin C experience fewer days with disease and have less severe symptoms, according to a placebo-controlled study from Oregon State University. But many multivitamin supplements do not contain enough vitamin D and it is very important for older people to get enough of this nutrient.
A panel of physicians and professors collaborating with the Swiss Society for Nutrition (SSN) recently reviewed the scientific evidence on the role of micronutrients in supporting a well-functioning immune defense for optimal health with particular focus on viral infections related to COVID-19. They conclude that there is widespread lack of vitamin C, vitamin D, selenium, zinc, and omega-3 fatty acids, all of which are crucial nutrients for the immune system. These deficiencies contribute to new waves of COVID-19 and can cause the infections to become life-threatening. The panel calls for immediate action with relevant focus on diet and supplements.
