Study Finds No Link Between Antioxidant Consumption And Stroke Or Dementia

February 20, 2013: 12:00 AM EST
A 14-year U.S./Dutch study of more than 5,000 people over age 55 who had no signs of dementia at the beginning found that total antioxidant levels in the diet were not associated with the risk of developing dementia or stroke. Data – which contradict earlier studies about the link between antioxidant consumption and the risk of stroke or dementia – were gathered from annual questionnaires about how often 170 foods were eaten in the past year. About 600 people developed dementia and about 600 people had a stroke. But researchers found that people with high levels of antioxidants were no more or less likely to develop brain disease than people with low levels.
