It is widely known that a diet high in fats can be harmful to our health. With recent reports on obesity and diabetes and the effects of sugar, it is no surprise that a new study in the Annals of Neurology has surfaced detailing the detrimental effects of saturated fats on the brain.
According to a report by Time, researchers at Brigham and Women’s Hospital in Boston conducted a study on 6,000 women over the age of 65 over the course of four years. At the start of the study, the women were asked to fill out a questionnaire that detailed their eating habits. Researchers then selected women to perform a series of “cognitive-function tests”, which were conducted every two years.
They found that women who consumed the largest amounts of saturated fats, which can be found in animal products like red meat and butter, had the poorest overall performance on the test during the four-year span. On the other hand, women who consumed monounsaturated fats, found in various plant-based sources nuts, olives, and avocados, “had better cognition and memory in that same time period.”
