Study Says Saturated Fat Is Bad For Brain Function

A new study from Brigham and Women’s Hospital found that, in addition to being bad for the heart, saturated fat is associated with worse cognitive function over time. The research looked at 6,000 women over the age of 65 and found those who ate the most saturated fat, which comes from animal fats such as red meat and butter, had more memory problems and worse cognitive function compared to women who ate the least amount. Also, the women who consumed the most monosaturated fats, such as olive oil, scored better on cognitive tests than those who ate the most saturated fats. Olivia Okereke, MD, MS, of BWH’s Department of Psychiatry, said the total amount of fat intake didn’t matter as much as the type of fat did. According to Okereke, substituting good fat in place of bad fat is a fairly simple dietary modification that could help prevent memory decline. More here and here.
