Chinese Army Medical University study: omega-3 supplements may speed cognitive decline
Fish oil could accelerate Alzheimer's decline, warns new research from China's Army Medical University.
A recent study from China's Army Medical University has raised concerns about omega-3 supplements, commonly taken by older adults for cognitive health. The research, focused on Alzheimer's disease, found that oral fish oil intake did not improve cognitive function and may even accelerate decline. This contradicts the long-held belief that omega-3 fatty acids protect the brain. The study adds to a growing body of evidence questioning the benefits of supplements when taken without underlying deficiencies.
The findings have significant implications for the multibillion-dollar supplement industry and the millions of elderly individuals who regularly consume fish oil. The researchers emphasize that more studies are needed to understand the mechanisms behind the potential harm. For now, the recommendation is to obtain omega-3s from food sources rather than supplements. The study was published by SCMP's science reporting team as part of a roundup of recent science highlights.
- Study by China's Army Medical University finds oral fish oil may not help and could speed up cognitive decline in Alzheimer's.
- Challenges the popular assumption that omega-3 supplements protect brain health in older adults.
- Researchers recommend obtaining omega-3s from food rather than relying on supplements.
