Fish oil boosts brain function in all adults
Partially trueThe Claim
It's commonly believed that omega-3 supplements can enhance cognitive abilities and prevent memory decline in all adults, not just those with existing cognitive impairments.
Origin
This myth is perpetuated by marketing claims and some early studies suggesting cognitive benefits from diets high in fish.
What Science Says
Research indicates the effects of omega-3 on brain health are more nuanced. A systematic review published in the Cochrane Database found that while omega-3s might benefit those with mild cognitive decline, they do not significantly enhance cognitive function in healthy adults. The effect is often too small to be clinically relevant.
Verdict
Partially True
