Fish consumption and risk of dementia

Previous studies have shown that fish consumption was associated with lower risk of developing dementia and stroke. Fish is a direct source of omega 3 fatty acids, a type of polyunsaturated fat that has been associated with a reduced risk of Alzheimer disease and cognitive impairment by their protective properties of nerve tissue and a normal functioning of the brain.

In summary:

This study suggests that fish prevents dementia

In a recent study, researchers examined whether consumption of fish and omega 3 fatty acids in the diet was associated with a cognitive impairment related to age among a large population of elderly.

Were studied more than 6,000 people older than 65 years who underwent various cognitive tests, obtaining their scores. The results showed a slight annual decline of scores on cognitive tests. Fish consumption was associated with a rate slower cognitive decline in mixed models adjusted for age, sex, race, education, cognitive activity, physical activity, alcohol consumption and total energy consumption. Cognitive decline was slower in people who consumed fish once a week and even slower if consumed fish two or more times per week, with a reduction of 10% to 13% annually.

The researchers conclude that fish consumption may be associated with a slower cognitive decline with age, although they argue that more studies are needed to determine whether the composition of fatty fish is the cause of this improvement.

It seems that fish consumption protects the brain from the effects of aging. Let’s eat fish!
