Fish oil supplements ‘do not protect brains from decline’

Fish oil supplements taken by millions of people to protect their brains from the ravages of age do nothing to slow natural mental decline, research suggests.

Scientists who monitored the progress of 4,000 study participants over five years found no evidence that omega-3 capsules kept them any sharper witted as they aged.

Other studies have associated regular fish consumption with lower rates of the eye condition age-related macular degeneration, heart disease, and dementia, as well as larger brain volumes.
