Dementia: High-mercury fish linked to brain condition – ‘Avoid overconsumption’

In his recent book, The End of Alzheimer’s Disease, the expert documents a number of cases similar to the study of a person who consumed too much mercury through fish.

However, there is currently not enough research to establish a firm link. Also, not all fish have the same level of mercury.

Mr Abdeh said: “It should be noted that high mercury fish are not the commonly found variety in supermarkets and restaurants, such as salmon or sardines.

“Therefore, people should not avoid these types of fish, as the protein, omega-3 and fatty acids they contain are invaluable for our health.

“Fish high in mercury are usually saltwater predators, such as swordfish, shark and king mackerel (not to be confused with common mackerel, which is very nutritious). Some freshwater fish also contain mercury.
