Starting to get a little forgetful? Then it’s time to take omega-3 fish oil supplements: they could help keep you mentally sharp, a new study has found.
People with mild cognitive impairment-which may even be a precursor of Alzheimer’s disease-could be helped by the supplements. Scans showed that inflammation in brain tissue was reduced after the volunteers started supplementing.
Interestingly, similar positive effects were not seen in people who already had Alzheimer’s, say researchers from the University of California’s department of surgery in Los Angeles.
Admittedly, the study group involved just 12 people with mild cognitive problems, seven of whom had already been diagnosed with Alzheimer’s. They all took the supplements for between four and 17 months.
The take-home message? Prevention is better than cure, and nutrition is every bit as important as physical and mental exercise, say the researchers.
