Men who take long-term supplements of beta-carotene -- an antioxidant found in carrots and other vegetables -- may enjoy less cognitive decline, according to a US study published Monday.
The study led by Francine Grodstein, of Brigham and Women's Hospital and Harvard Medical School, could have implications for the prevention of Alzheimer's and other debilitating mental conditions.
Beta-carotene, which gives carrots their orange color, is broken down by the liver to become a form of vitamin A and is also helpful against damage caused by free radicals. Other sources include spinach, sweet potatoes and coriander.
