Preterm babies have a risk of impaired vision, but if they are given supplements of omega-3 and omega-6 fatty acids at the age of two and half years their vision improves. This was demonstrated in a Swedish study that is published in The Lancet Regional Health – Europe. The scientists explain why these fatty acids are so important, not just for eye health but for the brain and for health in general.

- 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.

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.

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.

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 incurablebut 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.
