‘No link’ between fish oils and cognition in elderly



By Lilian Anekwe

The biggest trial to date of omega-3 long chain polyunsaturated fatty acid supplements has found no evidence that they offer benefits for cognitive function in older people.

A UK study published in the June issue of the American Journal of Clinical Nutrition found no benefit in taking fish oil supplements in cognitively healthy older adults.

Researchers looked at more than 800 people aged 70 to 79, comparing the effects of fish oil to a placebo of olive oil.

They found no significant difference in cognitive decline during two years of follow-up during the two years of study – but the authors cautioned that this may not have been long enough to see the real consequences of taking fish oil.
