In his recent book The End of Alzheimer’s Disease, the expert documented a number of similar cases in the study of the man who consumed too much mercury through fish.
However, there is currently not enough research to establish a strong link. Also, not all fish have the same level of mercury.
Abdeh said: “It should be noted that fish with a high mercury content are not the usual varieties found in supermarkets and restaurants, such as salmon or sardines.
“Therefore, people should not avoid this type of fish, as the proteins, omega-3s and fatty acids contained in them are invaluable to our health.
“Fish that have a high mercury content are usually saltwater predatory fish, such as swordfish, shark and mackerel (not to be confused with normal mackerel, which is very nutritious). freshwater fish also contain mercury. “
