Brain scans reveal for the first time that eating plenty of salmon, mackerel and sardines protects against Alzheimer’s by boosting blood flow and memory

Brain scans reveal for the first time that eating plenty of salmon, mackerel and sardines prevents Alzheimer’s disease by boosting blood flow, a study reveals.

Omega-3 fatty acids, found in oily fish, increase blood in brain regions that control memory and learning – both of which are destroyed by the neurological disorder, researchers found.

People who eat a lot of oily fish are also better at acquiring and understanding new information, the study adds.

A high-fish diet also boosts our overall mental and emotional health.
