Vitamin D is involved in the development of the brain structure and in brain functions. According to a review article that is published in Nutrients, vitamin D is of particularly great importance to the mental health of children and teenagers due to its long-term effect. This subject is highly topical as it is known that the widespread lack of vitamin D among children increases their risk of anxiety, depression, aggressive behavior, and other mental problems. It is vital for children and teenagers to get plenty of sun and supplements if necessary so they are sure to meet the new guidelines for vitamin D.
The immune system cannot function without vitamin D. In fact, blood levels of the nutrient should ideally be higher than the official threshold values for optimal protection against COVID-19 and other respiratory infections, according to a new study from the University of Chicago Medicine that is published in JAMA. An estimated 50 percent or so of the world’s population is believed to lack vitamin D, and people with dark skin are particularly vulnerable. It has been shown in previous studies that the majority of people who test positive for COVID-19 lack vitamin D. Therefore, scientists plan to look at whether daily vitamin D supplementation can help prevent COVID-19 infections or reduce serious symptoms. The researchers mention that it often takes high-dosed supplements to optimize levels of vitamin D in the blood.
Having higher blood levels of selenium, an essential trace element, increases a breast cancer patient’s chances of 10-year survival, according to a Polish population study that is published in the science journal Nutrients. Also, earlier research has shown that supplementation with selenium yeast can lower the risk of contracting a variety of different cancer forms. The agricultural soil in Europe is very low in selenium and that is one of the reasons why selenium deficiencies are so common. The question is how much selenium we need to optimize levels in the blood.
Type 2 diabetes is spreading like a bushfire with many people unaware that they have the disease. Diabetes increases your risk of cardiovascular disease, blood clots, and early death. A group of scientists from the University of St. Andrews in Scotland has looked closer at the different processes and studied the trace element zinc and its ability to improve the outcome of therapy by preventing dangerous blood clots. The new study is published in the Chemical Science journal. Zinc deficiencies are rather common and type 2 diabetes in itself increases the need for this nutrient.
Women who are overweight before becoming pregnant have an increased risk of abnormal fetal growth and low birth weight. However, it appears that fish oil supplementation can lower the risk of these complications, according to a new pilot study that is published in the science journal, Nutrients. The scientists behind the study explain how omega-3 fatty acids in fish oil support a healthy pregnancy and help control inflammation, insulin sensitivity, and lipid metabolism, all of which tend to be off balance in overweight pregnant women.

Vitamin D’s role in maintaining proper health is well documented. Still, many older people lack the nutrient and that increases their risk of bone fractures, blood poisoning, and disease complications that can eventually lead to hospitalization. Also, they risk prolonged hospitalization according to a new Irish study published in the scientific journal Nutrients. The scientists recommend giving vitamin D supplements to seniors to increase their blood levels of vitamin D. Other studies even suggest that this can protect against COVID-19, as low vitamin D status is associated with an increased risk of being hospitalized with the disease.
