Vitamin A’s key role in wound healing and stem cell biology
In the case of wounds or skin lesions, an active form of vitamin A regulates how stem cells initiate healing processes and produce new skin. This was demonstrated in a study from Rockefeller University that is published in the journal Science. In the future, researchers plan to look closer at how active vitamin A can be used to regulate stem cells as a way of preventing and treating skin cancer.
Overview of vitamins, minerals, and essential fatty acids
Vitamins, minerals, omega-3 and omega-6 fatty acids, and Q10 are nutrients that we need in certain quantities in order to support vital body functions. Nutritional supplements containing vitamins and minerals must be labeled in accordance with the reference values.

For decades, science has had its focus on vitamin D in terms of cancer prevention. A new study shows that this applies particularly to women older than 55 years. It may be because cancer often takes many years to develop and because our ability to utilize the vitamin decreases as we grow older.
Women who eat a healthy diet may prevent or delay their physical deterioration. But what type of diet has the best effect? And how can specific nutrients, which are difficult to get from the diet, improve the overall effect?
Many people suffer from insulin resistance that impairs the cellular uptake of glucose from the bloodstream. Insulin resistance typically causes untimely hunger or a craving for stimulants accompanied by fatigue, mood swings, tension, overweight, and numerous other problems that arise as a result of the cells producing too little energy. The condition increases the risk of type-2 diabetes, even among children. But how does magnesium affect our blood sugar levels, and how do we make sure to get enough of this nutrient?
It has long been known that vitamin D deficiencies increase the risk of sclerosis. According to a study that is published in JAMA Neurology, having too little vitamin D is even a problem during pregnancy, as it increases the child's risk of developing sclerosis later in life.
Inflammation appears to be a key factor in the majority of chronic illnesses such as e.g. rheumatism, type-2 diabetes, and cancer. Science has primarily focused on EPA (eicosapentaenoic acid), but new research points to supplementation with DHA (docosahexaenoic acid) as being even more effective in healthy patients with too much abdominal fat and subclinical systemic inflammation.
If you are pregnant it may be wise to eat salmon. According to a new study it lowers your child's risk of developing asthma, which is a rather common ailment. But what is it in salmon that prevents asthma, and what about those who dislike the taste of fish?
Low blood levels of vitamin D are associated with an increased risk of breast cancer. Also, breast cancer patients with optimal levels of vitamin D in their blood can expect to live longer than breast cancer patients with low blood levels of the nutrient. But how much vitamin D is needed to prevent the dreaded disease?
Cataracts is a common cause of impaired vision, especially among the elderly. However, a new study of twins and the impact of genetic and environmental factors shows that higher intake of vitamin C may have help prevent this eye disease.
