A diet high in monounsaturated fatty acids may be associated with less cognitive decline in older healthy women, according to a study published in the Journal of the American Geriatrics Society. Previous research has linked cognitive decline with cardiovascular disease, and certain types of dietary fatty acids (saturated and trans) are a known risk factor for cardiovascular disease. However, in this study, no association was found between cognitive decline and saturated or trans fatty acids. Monounsaturated fats are found in olive and canola oils, and saturated fats are found in coconut and palm oils as well as in butter, cheese, milk, and fatty meats. Trans fats are found in some margarines, commercial baked goods, and other foods made with or fried in partially hydrogenated oil.
