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.

During a woman’s pregnancy, vitamin D is important for the growth, development, and general health of the baby. Apparently, maternal vitamin D deficiency during pregnancy increases the risk of boys developing more fat tissue during their first years of life, which makes them more prone to overweight in childhood and later in life. This was reported in a Spanish population study that is published in Nutrients. Because both overweight and vitamin D deficiency are so widespread, it is essential for pregnant women to make sure as a minimum to follow the official recommendations for vitamin D supplementation. Also, there is no read to avoid sun exposure because sunshine is our primary vitamin D source during the summer period. Just make sure not to get a sunburn.

Heart failure is a disease with a variety of different symptoms and a high mortality rate because the heart’s pumping function is impaired. Heart failure is also characterized by chronic inflammation that worsens the prognosis. Apparently, fish oil supplementation can reduce chronic inflammation, according to a meta-analysis that is published in Heart Failure Reviews. In fact, eating more omega-3 fatty acids from fish and different plant sources can improve survival in heart failure.

- with non-alcoholic fatty liver disease

Weight-challenged children and teenagers have grown to become a global health threat, and the problem became even worse during the corona pandemic. Overweight is linked to a number of health problems, including non-alcoholic fatty liver disease that sets the stage for type 2 diabetes and other serious ailments. In a new review article that is published in Nutrients, researchers look closer at how a carbohydrate-restricted diet or the traditional Mediterranean diet can help to counteract the development of overweight and non-alcoholic fatty liver disease. Also, supplementation with vitamin E, vitamin D, fish oil, and probiotics can block the development of non-alcoholic fatty liver via different metabolic parameters.
