Can omega-3 fatty acids boost memory?

Do you eat fish and take fish oil supplements?

There is mounting evidence that diets high in omega-3 fatty acids from fish may protect people from cognitive deficit and dementia.

Only recently has the strength of this potential protective power been tested in controlled clinical trials.

In observational studies researchers compare people’s estimated omega-3 intakes to their brain-health status.

Epidemiological studies can detect statistical correlations between omega-3 intakes and brain health, but they cannot prove them.

For the entire article.

Remember that one of the best source for omega-3 fatty acids is found in fish such as wild Alaskan salmon, halibut, anchovies, tuna and sardines.

Author of the omega-3 effectDr. William Sears recommends eating fish 3 to 4 times a week if you can.

Buy your fish from a reputable source and make sure that is wild caught and not farmed. Try supplementing with fish oils as well.
