For decades, we’ve been told how dangerous the sun is and how important it is to protect ourselves. Now, a large British population study of more than half a million participants reveals that getting more sun exposure – even using tanning beds – is linked to fewer deaths from cardiovascular disease, cancer, and other things. The explanation lies in the UVB rays, which are the best way to get essential vitamin D, but only when the sun sits sufficiently high in the sky. It appears that all the sun awareness campaigns have done more harm than good, because it is vital to get enough sunlight, as long as we don’t get burned. The British study supports an earlier Swedish population study that revealed that lack of sun is every bit as harmful as smoking. People should take a vitamin D supplement during the winter period, and those who don’t get enough sun or who have difficulty with synthesizing vitamin D should supplement all year round.
Vitamin D prevents influenza and respiratory infections
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.
Climate changes and soil depletion increase the risk of selenium deficiency, especially in Europe as shown by Swiss scientists. Selenium is an essential nutrient, and existing studies clearly show that low selenium intake increases the risk of cancer, metabolic disorders, impaired immunity, poor sperm quality, and atherosclerosis. Selenium deficiencies are therefore to be taken seriously and should be prevented one way or another. A good way to get enough of the nutrient is by taking a high-quality selenium supplement.
Despite official recommendations to give infants a daily vitamin D supplement, nearly 50% of parents forget to follow this advice according to a large new Danish study. Not only do the children risk weak bones, it also increases their risk of infections and autism, other studies suggest.
It is common knowledge that omega-3 fatty acids are vital for our brain development and nervous system. Now, researchers from Harvard Medical School in the United States have discovered that they also play an important role in maintaining the blood-brain barrier that protects the central nervous system against bacteria and toxins.
A new British study that is published in British Journal of Nutrition shows that getting too little vitamin D during pregnancy has a negative effect on the social development and motor skills of the toddler. Vitamin D is believed to play a role in brain development. It is vital for the pregnant mother to pay careful attention to getting enough vitamin D all year round, as our modern lifestyle with indoor activities, our frequent use of sunscreen with high sun factor, being overweight, and having dark skin contribute to the widespread deficiency of this nutrient.
An estimated 350 million people worldwide suffer from depression, a disease with huge economic and human costs. Not everyone benefits from the traditional medical treatment, which can even cause various side effects, so there is every reason in the world to aim for more prevention and better therapies. A new study that is published in PLoS One shows that magnesium supplements are effective as an adjuvant in mild or moderate depression. The researchers have also discovered which biochemical effect magnesium has on mood.
"After about one week of taking the Q10 supplement I could feel a huge difference," says 23-year old Alan Piccini, who has been suffering from extreme fatigue and muscle aches ever since he was a child.
“Taking capsules with co-enzyme Q10 has freed me of the severe side effects of my cholesterol lowering medicine,” Mrs Franken explains.
