1. A study cited in an article from Harvard University suggests your diet could have a significant impact on your memory as you age. Scientists at Brigham and Women's Hospital published a study within the "Annals of Neurology" that suggested women who ate high levels of saturated fat in foods like red meat and butter didn't perform as well on memory tests than women who regularly consumed less saturated fat. Researchers haven't yet discovered the connection between saturated fat and memory, but they hypothesize it could have something to do with a person's genes. Scientists and doctors have long recommended that patients work to control their cholesterol levels as they age to protect the memory during the aging process.
