The rate of inflammatory bowel diseases like ulcerous colitis is growing, and diet plays a major role. Even if you eat a healthy diet, it can be a challenge to get enough selenium because of the selenium-depleted soil in our part of the world. Apparently, selenium supplementation can lower the disease activity and improve quality of life in patients with ulcerous colitis.

It is mainly older people and those with chronic illnesses that are vulnerable to COVID-19 and other respiratory infections. Also, it’s a fact that lack of essential nutrients impairs your immune defense and may have serious health consequences, whether you are vaccinated or not. A large study of 19 European countries reveals that low blood levels of vitamin D increases the risk of complicated COVID-19 infections, hospitalization, and death. According to the scientists, it is necessary to discuss and optimize people’s vitamin D status to help them resist future pandemics.

Menopause is typically linked to hormonal changes that increase the risk of aching joints, overweight, cardiovascular disease, muscle weakness, and metabolic disturbances. According to a study published in Nutrients, however, high-dosed supplementation with fish oil for eight weeks has a positive effect on blood pressure, muscle strength, chronic inflammation, and oxidative stress, which can otherwise set the stage for atherosclerosis, joint pain, and number of chronic ailments. Earlier research has also demonstrated that fish oil supplements help against dry mucous membranes and depression that are often caused by brain inflammation.

Vitamin D is important for our bones, immune defense, muscles, hormone balance, blood sugar levels, nervous system, and for preventing cancer. According to a Polish study of elderly people hospitalized in geriatric wards, lack of vitamin D may trigger a host of different diseases and possibly be a useful marker of comorbidities and length of hospital stay. This study is highly relevant as the widespread problems with vitamin D deficiency have serious health-related and socioeconomic consequences, which could otherwise be avoided conveniently and at low cost with supplementation.

Lung fibrosis is a condition characterized by accelerating scarring of lung tissue, which impairs breathing, reduces the oxygen level in the blood, and lowers the cellular energy turnover. Some types of lung fibrosis are very aggressive and there is currently no cure. Healthy omega-3 fatty acids from oily fish and fish oil supplements may delay the progression of the disease and postpone the immediate need for lung transplants, according to a study that is published in the journal CHEST.

The number of older people is constantly increasing, and more and more people suffer from Alzheimer’s disease and other types of dementia. Apparently, seniors who take a daily multivitamin can improve their memory and slow down their cognitive decline, according to a meta-analysis that is published in Journal of Clinical Nutrition. Older people generally have increased need for certain vitamins and minerals because of poor nutrient absorption in the digestive system, impaired enzyme functions, oxidative stress, and regular use of medical drugs that can interact with the nutrients. But how do different vitamins and minerals affect brain health?

Newly diagnosed cancer patients often lack selenium. Not only does this contribute to the development of the disease, but it also worsens the prognosis. An estimated one billion people worldwide are selenium-deficient and there are many things that can explain it. High-doses selenium supplementation of cancer patients seems to have a positive effect on their health and quality of life during rehabilitation, and the best effect is seen when blood selenium levels remain high, according to a German study published in Nutrients.

Epidemiological studies have shown that relatively high doses of omega-3 fatty acids that are found in oily fish and fish oil supplements have a positive effect on neurodegenerative diseases such as sclerosis, but the underlying mechanisms are not known. A mouse study reveals that one particular omega-3 fatty acid is able to control the immune defense and regulate the inflammatory processes in the central nervous system.

Headache, aching joints, and other types of chronic pain are typically caused by myofascial pain syndrome, which is characterized by localized pain. There can be many underlying causes of this condition, but according to a Thai study published in BMC Nutrition, lack of sunshine and too little vitamin D are quite common among patients. Magnesium therapy may also have an effect, according to a study published in BMC Oral Health.

As we grow older, our risk of hearing loss increases, and our diet plays a major role. Apparently, there is a link between hearing loss and being deficient in an omega-3 fatty acid that we get from oily fish and fish oil supplements. This was seen in a study that was presented in Boston at a meeting for the American Society for Nutrition – an American company for professional researchers and practitioners in nutrition. The scientists mention that increased intake of this particular omega-3 fatty acid from the diet or from supplements may help prevent hearing loss.

A chronic cough often follows in the wake of virus infections such as colds, influenza, and COVID-19. Lack of vitamin D seems to be a major contributor, coupled with the fact that a vitamin D deficiency often increases during the disease period. Vitamin D is of vital importance to a strong immune defense and also helps to regulate inflammation. Therefore, supplementation with vitamin D may be worth considering as a way of preventing virus infections and treating complications such as chronic cough, according to two studies that are published in European Respiratory Journal.
