Certain Types of Fish
Fish has been described as ‘brain food’ well before any research was carried out to prove that actually it really is a good food to eat to help your brain. The best fish to eat are cold water fatty fish because of the omega 3 fatty acids that they contain. This group of fish includes mackerel, herring, sardines and salmon. King mackerel and tuna also have lots omega 3 fatty acids present but there is a concern about the amount of mercury which builds up in their bodies.
Omega 3s appear to be the reason why eating one or two portions of fatty fish every week can reduce the chances of developing Alzheimer’s disease. They also coat the neurons within the brain, that’s the nerve endings, with the fatty acids which prevents cholesterol and saturated fats from causing negative effects.
