Zinc strengthens the immune defense and controls inflammatory conditions such as eczema. According to a Finnish meta-analysis, high-dosed zinc supplements can help the immune defense fight a regular cold much faster. It turns out that there are widespread zinc deficiencies. First of all, sugar, birth control pills, inorganic iron supplements, and normal ageing processes impair the body’s zinc uptake. Secondly, it may be difficult to get enough zinc if you are on a vegetarian or vegan diet. Not only does a zinc deficiency have a negative effect on your immune defense and skin health, it also upsets the countless enzymatic processes in which zinc is involved.

Even if you eat a healthy and balanced diet, it can be difficult to get enough selenium because of climate changes and nutrient depletion of the soil, especially in Europe. This was shown in a study conducted by Swiss scientists. Selenium is very important for the immune system, but how much do we need to be optimally protected against infections? There also appears to be a connection between widespread selenium deficiency and the increased rate of cancer.
It is hardly a coincidence that so many of us contract virus infections in the course of the winter. It is because we lack vitamin D, which we are unable to synthesize when the sun sits too low in the sky. Danish scientists have discovered how vitamin D activates the immune system, and a comprehensive meta-analysis shows how vitamin D supplements can prevent colds, flus, and related complications.
During the winter period, many of us have runny noses and some may end up in bed with a bout of flu. Now is the time to prime your immune system by getting all those vitamins and minerals that your diet is not always able to provide you. That way you can ward off germs and avoid unnecessary sick days. But what effect does vitamin C, vitamin D, selenium, and zinc have on the immune system’s different “troops”, and how much do we need?
Clostridium difficile is a bacterium that causes diarrhea and intestinal infection. The infection may even be life-threatening. A new American study that is published in PLoS Pathogens shows that this bacterium can only thrive with an overload of calcium in the intestinal system. Such a calcium excess can be caused by overconsumption of calcium, lack of vitamin D, and regular use of antacids.
Researchers from Sweden and England have discovered a link between vitamin A and diabetes. According to their new study, vitamin A is essential for enabling pancreatic beta cells to produce insulin, the hormone that helps cells take up sugar. This discovery could open new doors to better diabetes therapies in the future. However, it is also important to focus on diet, weight management, and the intake of other nutrients like chromium for proper blood sugar control, which is necessary for preventing and treating diabetes.
