A big, new long-term study suggests that sticking to a healthy diet can cut your risk of developing Alzheimer's, especially if you were born with genetic risk factors. The study, from nutrition and genetics researchers at Harvard Medical School and Mass General Brigham, compared the genes and diets of 16,497 women and 9,828 men across the US, over three decades. The study tracked cognitive changes in the participants, keeping tabs on what people ate and to what extent they followed a typically Mediterranean diet pattern, filled with fresh vegetables, olive oil, nuts, fish, and legumes. Many studies have shown that a Mediterranean-style diet, filled with key nutrients in ingredients like fatty fish, beans, and nuts, can help reduce dementia risk and promote brain health. This is the first time, however, that a study has shown that people at higher genetic risk of developing Alzheimer's derive even more cognitive benefits from such a diet.
