Many Alzheimer's researchers have long touted fish oil, by pill or diet, as an accessible and inexpensive "weapon" that may delay or prevent this debilitating disease. Now, UCLA scientists have confirmed that fish oil is indeed a deterrent against Alzheimer's, and they have identified the reasons why.
associate director of UCLA's Alzheimer Disease Research Center, and his colleagues report that the omega-3 fatty acid docosahexaenoic acid (DHA) found in fish oil increases the production of LR11, a protein that is found at reduced levels in Alzheimer's patients and which is known to destroy the protein that forms the "plaques" associated with the disease.
We found that even low doses of DHA increased the levels of LR11 in rat neurons
Based on the positive results, the National Institutes of Health is currently conducting a large-scale clinical trial with DHA in patients with established Alzheimer's disease.
This research is reported in the Journal of Neuroscience, now online.
