Fish Oil Supplements May Not Aid Old Brain

LONDON, April 22 (UPI) — British researchers said fish oil supplements may not boost cognitive function in older people.

Researchers at the London School of Hygiene & Tropical Medicine said they found no evidence taking fish oil supplements over a two-year period helped study participants maintain cognitive health.

The study, published in the American Journal of Clinical Nutrition, enrolled 867 participants ages 70-80 with good cognitive health who were randomly assigned to take either fish oil or a placebo. Memory and concentration at the start and end of the study were assessed using paper and pencil tests.

Participants receiving fish oil capsules had significantly higher levels of omega-3 fatty acids in their blood than those receiving placebo capsules, but cognitive function did not change in either group, the study said.

However, study leader Alan Dangour suggested caution when interpreting the results.

“It may be that it was not long enough for any true beneficial effects to be detected among this healthy cohort of older people,” Dangour said in a statement.
