From PsychologyToday.com:
It sounds like a bad joke, but fish can stop dementia in its tracks. A team of California researchers found that a diet rich in fatty oils from cold-water fish can halt the progression of dementia – even in those who may be genetically predisposed to Alzheimer's disease.
The good news, says UCLA neuroscientist Greg M. Cole, is that "we can buy the therapy at a supermarket or drug store." His study showed that animals fed a diet enriched with DHA, or docosahexanenoic acid, an omega-3 fatty acid found in relatively high concentrations in salmon, mackerel and sardines, dramatically cut the harmful brain plaque that marks Alzheimer's disease and appears to precipitate memory decline.
At a time when we've become so fat-phobic, it's important to remember that some fats are beneficial. DHA helps maintain the flexibility of cell membranes, which facilitate communication between brain and nerve cells.
