Grape seed extract is rich in antioxidant polyphenols. Some research has suggested that these compounds might help protect the brain from the degeneration that leads to Alzheimer's disease. Scientists studied the compound in mice genetically engineered to develop Alzheimer's-like brain pathology. They found that the mice who received grape-derived polyphenols were less likely to accumulate beta amyloid, a substance linked to Alzheimer's disease. The investigators point out that the compound is commercially available in health food stores and is now being tested in patients with Alzheimer's disease.[Journal of Alzheimer's Disease, online July 15, 2011]
