The diet’s content of vitamin C, vitamin B6, vitamin B12, folic acid, and other vitamins has a positive impact on our mental and physical health and well-being Lack of vitamins may even remedy depression and chronic pain, according to a Japanese study of seniors. The number of seniors worldwide is increasing with more and more people being affected by physical and mental disease. Therefore, scientists want to take a closer look at the diet and its influence on quality of life measured by different accounts.

Neurologists agree that the brain’s neurons constantly change in relation to stimuli from the inside and outside environment. That is how we learn new skills and develop our memory. The brain’s ability to adapt and change is called neuroplasticity and doctors have suspected for a long time that it takes place in the synapses. A team of scientists from the University of Freiburg in Germany has discovered that a vitamin A-like compound affects the neurons and their ability to adapt to structure and function. The scientists hope that their discovery can contribute to the development of new therapies for treating brain disorders. Earlier studies have shown that omega-3 fatty acids, vitamin D, and lifestyle in general also affect the brain’s neuroplasticity and development.

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.

- for longer periods

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.

According to a retrospective study of older COVID-19 patients, lack of vitamin D is linked to serious lung symptoms, longer disease duration, and increased risk of death. The problem is made worse by the fact that vitamin D deficiencies are so common among older people, nursing home residents, and exposed population groups. According to a new study published in Nutrients, doctors and scientists advise governments worldwide to include vitamin D supplementation in their campaigns and strategies for fighting COVID-19 and mutations of the virus. The study supports earlier research showing that lack of vitamin D is a risk factor for all age groups. The question is how much vitamin D does one need to have optimal levels of the nutrient in the blood?

Cholesterol-lowering statins are among some of the most widely sold medical drugs. However, there is growing disagreement about their preventive effect on atherosclerosis and cardiovascular diseases, which are linked to many other factors than cholesterol levels alone. It turns out that statins also block the body’s production of vitamin K2, a nutrient that contributes to removing calcium from the bloodstream. A new study that is published in Medical Sciences concludes that atherosclerosis is more prevalent among statin users than among non-users, regardless of any cardiovascular diseases that have already been diagnosed. In other words, statins actually increase your risk of clogged-up arteries and that contradicts the traditional view. The new study supports earlier research, and it has been known for years that statins also block the endogenous synthesis of coenzyme Q10 and vitamin D, both of which are important for the heart and circulatory system.

Vitamin D is vital for normal development of the baby’s bones, cognitive skills, IQ, immune defense, and a number of other things. According to a new British study, however, a third of white infants lack vitamin D. The problem is even more pronounced in dark-skinned babies. Here, around half of them lack vitamin D. More focus is needed on pregnant women from exposed groups to help ensure that they get adequate amounts of the nutrient.
