A healthy diet full of fish, vegetables and healthy fats could help to preserve cognition.
“This remains an intriguing open question,” Ballarini said. “Following a Mediterranean diet could act on specific mechanisms related to Alzheimer’s disease neuropathology, for example, by modulating neuroinflammation, or it could sustain brain health through systemic effects, for example, by fostering cardiovascular health.”
The main message of this study is that healthy lifestyles can help preserve cognition, said Dr. Oscar Lopez, a professor of neurology at the University of Pittsburgh School of Medicine. What the study can’t tell is whether the diet is helping the brain or if it’s just a marker for an overall healthy lifestyle, Lopez said. “People who are eating healthy are more likely to see their doctors more often, to be better educated and to be involved with cognitively stimulating activities,” he added. “So it’s a constellation of activities that happen around a healthy diet.”
Nevertheless, Lopez said, eating a Mediterranean diet has been shown to be good for you in other ways, so even if it weren’t proven to preserve brain function, it’s going to keep you healthy.Linda Carroll is a Peabody Award-winning journalist who is a contributing health and medicine writer for NBC News and TODAY.
