Elevated blood pressure causes more premature deaths worldwide than any other factor. Blood pressure is regulated by a number of things such as diet and lifestyle. Science has also discovered that low blood levels of zinc contribute to high blood pressure because it impairs the ability of the kidneys to regulate sodium levels. This was demonstrated recently in a study that is published in American Journal of Physiology – Renal Physiology. Clinical zinc deficiencies are especially common among type 2 diabetics and people with kidney ailments. Subclinical zinc deficiency is also quite common. Even if you get plenty of zinc from your diet, the risk of poor zinc absorption increases with age. Vegetarian and vegan diets, overconsumption of calcium, drinking too much alcohol, using birth control pills and several types of medicine, plus certain other factors can also increase the risk of a zinc deficiency.

Tuberculosis (or TB) is one of most widespread diseases in the world. It claims millions of human lives every year, especially in underdeveloped countries. A team of scientists from Queen Mary University in London has discovered that vitamin D supplements can support therapies used in the treatment of multi-resistant TB, which can otherwise last quite a long time and comes at a considerable cost. Earlier studies have shown that vitamin D generally helps prevent the disease by supporting the immune system in different ways.

Stress is associated with a host of physical and psychological health problems such as headache, fatigue, tension, insomnia, sore throat, constipation, flu-like symptoms, depression, and anxiety. Stress is not all in your mind. It is a physiological condition that affects the whole body and increases your need for specific nutrients. Earlier studies carried out with humans and animals have shown that supplements of magnesium and vitamin B6 both have the potential to reduce stress symptoms. Now, a team of French scientists has carried out a randomized study showing for the first time ever that a combination of magnesium and vitamin B6 administered to people with severe stress and magnesium deficiency works better than magnesium supplementation alone.

All cells in the body depend on vitamin D. Unfortunately, many people lack the nutrient, and the list of diseases caused by too little vitamin D is growing. A new study from Trinity College in Dublin shows that it is possible to measure vitamin D levels in hair, and this can reveal the large fluctuations that occur in the course of a year, and which an ordinary blood test fails to show. The scientists can see a huge potential with this new type of measurement, which can even be used on historical populations such as the ancient Egyptians or on prehistoric animals such as the mammoths.

Scientists from Queensland in Australia have discovered that vitamin D is of vital importance to the structure and health of the brain. Also, deficiencies of the nutrient may lead to dysfunctions and loss of cognitive skills plus depression and schizophrenia. More than one billion people worldwide are believed to lack vitamin D. This may have widespread consequences for their health and may even be linked to the huge increase in mental illnesses.

- and for the utilization of other nutrients

A healthy and regular digestion requires magnesium, a nutrient with several different mechanisms of action. Irritable bowel syndrome and constipation, both of which impair quality of life, are linked different conditions such as headache, bad mood, eczema, and aching joints. It is therefore essential to address such digestive disorders. In this article, we will take a closer look at magnesium and its role in a healthy digestive system as well as why magnesium deficiencies are so common.

An increased intake of B vitamins can help improve concentration and other cognitive skills in young patients that are about to develop schizophrenia and other psychoses, according to a study conducted by scientists from Orygen, the National Centre of Excellence in Youth Mental Health, Australia. Here, it is important to consider all the different factors that may lead to a deficiency of the essential B vitamins, including unhealthy diets, too much sugar, energy beverages, alcohol, and other stimulants. It appears that the unhealthy lifestyle that many youngsters have increases their risk of psychoses. It is therefore not enough to treat them with anti-psychotic drugs and psychological therapy, if the brain and the nervous system lack essential nutrients.

According to a study from Columbia University’s College of Dental Medicine and Vagelos College of Physicians and Surgeons, there are certain compounds in fish oil that can prevent pregnancy complications that follow in the wake of a regular bacterial infection. These complications include miscarriage, preterm delivery, and infant death. There are an estimated 15 million premature deliveries per year on a global scale, and each year around one million babies die as a result of this. Preterm infants also have an increased risk of vision impairment, retarded physical development, and learning disabilities. The researchers therefore suggest new strategies for recommending nutritional supplements and fish oil supplements during pregnancy.

Most people think of vitamin C in connection with the immune defense, but as it turns out, the largest concentration of vitamin C is actually found in the brain. This is because vitamin C is enormously important for the energy turnover, the nervous system, and the cognitive skills, and this is described in a new review article. There is also evidence of widespread vitamin C deficiency, which may eventually impair cognitive skills and increase the risk of dementia and Alzheimer’s disease. If a pregnant woman lacks vitamin C, it can disrupt the development of the baby’s brain. There is a number of factors that increase our need for the nutrient, so the big question is how much do we need to secure optimal brain function throughout life?
