Summary
Researchers in the United States have discovered that curcumin, the yellow pigment in turmeric, and cold water fish such as salmon, sardines, halibut and mackerel can help fight Alzheimer's disease. Turmeric, which is used frequently in Indian cooking, seems to be the reason that so few Indians suffer from dementia late in life. As well, cold water fish are high in docosahexenoic acid (DHA), which helps prevent plaque formation in the brains of Alzheimer's patients.

Details
- Curcumin, the yellow pigment in turmeric, may be the key to the low prevalence of dementia among the elderly in India, where the spice is used in most foods, a team of US researchers has said.
- A team of researchers led by Greg M Cole, a neuroscientist at the Greater Los Angeles VA Healthcare System, identified curcumin as a potential cure to prevent or treat Alzheimer's disease after they discovered low rates of dementia in India, according to the US Department of Veterans' Affairs.
- The Cole team identified curcumin as a nutrient that appears to combat Alzheimer's plaques.
- They also found that a diet high in docosahexenoic acid or DHA -- an omega-3 fatty acid found in relatively high concentrations in cold-water fish -- dramatically slowed the progression of Alzheimer's in mice.
- "Specifically, DHA cut the harmful brain plaques that mark the disease," the team found.
- The results appear in the March 23 online edition of the Journal of Neuroscience.
- Greg said that unlike many studies with mice, this one points to the benefits of a therapy that is easily available and already recommended for other medical conditions.
- DHA -- either from food sources such as fish and soy, or in fish-oil supplements -- is recommended by many cardiologists for a healthy heart.
- "The good news from this study is that we can buy the therapy at a supermarket or drug store," Cole was quoted as saying.
- "DHA has a tremendous safety profile -- essentially no side effects -- and clinical trial evidence supports giving DHA supplements to people at risk for cardiovascular disease."
- Omega-3 fatty acids are deficient in the American diet, although they are essential for human health.
- DHA in particular is vital to proper brain function, as well as eye health and other body processes.
