People who eat omega-3 fatty acids may have a lower risk of Alzheimer’s later in life say researchers from Aberdeen University. 120 over-64s were given written intelligence tests and gave blood samples for analysis. There was a clear link between better results and the presence of omega-3s, but only in those missing a particular gene thought to predispose to Alzheimer’s. In those with the gene present, the omega-3 fats made no difference to their test scores. Omega-3s are a type of polyunsaturated fat; good vegetarian sources include flaxseeds (linseeds), walnuts and their oils.

People with high cholesterol levels in mid-life are more likely to develop Alzheimer’s disease than those with low cholesterol according to new research from California. From a group of 9,752 people (whose cholesterol had been measured in their 40s) 504 developed Alzheimer’s. The study revealed that those with high cholesterol levels in mid-life were 50 per cent more likely to develop this disease later in life.

Dr. Justine Butler
I joined Viva! as a health campaigner in 2005 after graduating from Bristol University with a PhD in molecular biology. My scientific training helped me research and write numerous reports, guides and fact sheets for Viva! including Meat the Truth, Fish-Free for Life, One in Nine (breast cancer and diet) and the substantial report on the detrimental health effects of consuming dairy; White Lies. This accompanied Viva!’s report The Dark Side of Dairy which spelt out the inherent cruelty of dairy farming. We were the first UK group to take on the dairy industry in this way, and many of our supporters go vegan after reading these reports.
