Alzheimer’s disease: More omega-3 can cut your risk in half
Alzheimer’s is an insidious disease and the leading cause of dementia. It’s also one of the major causes of death in old age. Diet plays a major role in preventing the disease. In fact, having high concentrations of the omega-3 fatty acid, DHA, in the blood can halve the risk of developing Alzheimer’s disease, according to a study that is published in Nutrients. DHA (docosahexaenoic acid) is found in oily fish and fish oil supplements. This essential fatty acid is also found in all our cell membranes (including nerve cells) and plays a key role in maintaining our general health and cognitive skills. Unfortunately, modern diets contain far too little omega-3, but science is not quite sure how much we need.
