Monkey Research Shows How Omega-3 Fatty Acids Help the Brain
New research in monkeys suggests that eating a diet rich in omega-3 fatty acids may boost the development of complex brain networks. Scientists found that monkeys fed a diet high in omega-3s had better connections in certain brain networks. They noted these connections are similar to those found in people, including networks involved in thinking and attention. The study authors said their findings offer more evidence that omega-3 fatty acids are important ...
