The trace element chromium improves the effect of insulin, the hormone that helps glucose enter our cells. Chromium is needed for normal sugar metabolism that is closely linked to normal lipid metabolism and weight control. According to a new study of rodents, a chromium-deficient diet that is rich in carbohydrate and fat, increases hunger and energy intake. Also, levels of insulin and lipids in the blood increase, and there is weight gain and an increased risk of developing type 2 diabetes. The new study supports earlier studies of humans where it was seen that chromium is important for both blood sugar levels and weight control. When using chromium supplements, make sure to choose a product with chromium yeast that has good absorption. Also make sure to get plenty of protein that contributes to blood sugar management and fat burning, which makes it easier to lose weight.

Brain cancer is associated with physical and cognitive disruptions, and many patients die within a few years. Compared with other cancers, the development of brain cancer is more complex and there has been focus on underlying causes such as head traumas, allergies, and electromagnetic radiation from cell phones, transmission towers, etc. Scientists have also looked at vitamins and brain health, whereas minerals have been ignored. Now, a team of Chinese scientists have conducted a large population study and found that higher intake of calcium, magnesium, iron, zinc, and copper is linked to a reduced risk of different types of brain cancer (gliomas). Apparently, selenium also has a protective effect.

Cardiovascular disease is the leading cause of death worldwide, and our diet and lifestyle play a major role. According to an Australian study published in British Medical Journal, high-dosed vitamin D supplementation taken for several years lowers the risk of heart attacks or interventions such as angioplasty and by-pass surgery in people aged 60 years and older.

Zinc is involved in numerous physiological functions, some of which are important for pregnancy and fetal development. However, zinc deficiencies are common, especially in developing countries. Vegans are also at increased risk because it is difficult for the body to absorb zinc from a plant-based diet. Zinc deficiency in connection with pregnancy appears to increase the expecting mother’s risk of developing hypertension, and the elevated blood pressure may result in low birth weight and a low Apgar score, which is a health assessment of the baby in the minutes right after delivery. This was shown in a study that is published in Frontiers in Nutrition.

Around 25 percent of adults have had canker sores, also referred to as recurrent aphthous stomatitis (RAS). The condition is characterized by painful, superficial sores, and we don’t know all that much about what causes it or how to treat it. However, according to a meta-analysis that is published in Frontiers in Nutrition, a possible cause may be low blood levels of vitamin D, a nutrient with a key role in oral health and immune defense.

Neurological disorders such as Alzheimer’s disease, dementia, depression, Parkinson’s disease, stroke, migraine, and fibromyalgia are rather common. These conditions are a result of imbalances in the nervous system, and they are often insidious. In a new review article that is published in Frontiers in Neuroscience, researchers have studied Q10’s role in the different neurological disorders. The reason for this is that Q10 is important for cellular energy turnover and serves as an antioxidant that protects the circulatory system and the nerve cells against oxidative damage. As we grow older, our endogenous Q10 synthesis decreases, and certain diseases and medical drugs also impair the body’s Q10 synthesis.

ALS (amyotrophic lateral sclerosis) is a potentially life-threatening disease that affects the spinal cord and the motor nerves of the brain. The disease is incurable but according to an American study that is published in Neurology, it progresses at a slower rate in patients with a higher intake of omega-3 fatty acids from different dietary sources.

Impaired fertility and involuntary childlessness are common in the Nordic countries and there can be a number of reasons for these serious problems. However, according to a large Finnish study that is published in Nutrients, vitamin D deficiency, which is a widespread problem, may increase women’s risk of fertility problems and cause them to have a miscarriage.

Most chronic pulmonary diseases – including asthma, bronchitis, and COPD (Chronic Obstructive Pulmonary Disease) – are characterized by chronic inflammation that makes both the symptoms and the prognosis worse. Fish and fish oil supplements contain specific omega-3 fatty acids that appear to have an anti-inflammatory effect and may therefore be useful as both prevention and therapy for chronic pulmonary diseases. This was demonstrated in a large American population study that also included Europeans. What the researchers also mention is that people who fail to meet the official guidelines for fish consumption are often at increased risk of developing chronic lung diseases.

- which lowers your stress threshold and threatens your health

Stress and magnesium deficiency are widespread problems in the general population. It’s a vicious cycle that increases the risk of fatigue, headaches, constipation, nervousness, insomnia, infections, depression, metabolic syndrome, and a number of physical and mental diseases. In a review article that is published in Nutrients, the authors look closer at magnesium’s key role in the body’s physiological stress response. They also address the fact that stress increases the need for magnesium. Moreover, nutrient-depleted soil, unhealthy diets, too much coffee, alcohol, and calcium plus certain types of medicine, intensive sport, menopause, and ageing increase the need for magnesium even more.
