A US expert said diet was just one aspect of the Alzheimer’s picture.
“We continue to see the literature revolve around nutrition and its importance in later life,” said Heather Snyder, vice president of medical and scientific relations for the Alzheimer’s Association.
However, diet is not the only lifestyle factor that could lower the risk of Alzheimer’s, she said.
“I think the data is evolving and shows that lifestyle interventions are likely to help reduce cognitive decline,” said Snyder.
Other lifestyle components like exercise are also important, she said. It is not yet clear how diet and exercise lower the risk of Alzheimer’s disease.
“I think the key is to really understand what this recipe is because it’s unlikely to be anything,” said Snyder. “It is more likely that a combination and synergy of these behaviors will be most beneficial.”
Snyder noted that the same lifestyle factors help reduce the risk of cardiovascular disease and even some cancers. “But there is a need to find out how and what could be most beneficial for each of them,” she added.
“When we look at Alzheimer’s, cognition, and cognitive decline, we’ve seen time and time again that diets like the Mediterranean Diet are associated with lower risk later in life. What they all have in common is that a balanced diet ensures that your brain has the nutrients you need. which needs it contains, “said Snyder.
“I think we know what’s good for your heart is good for your brain. So eat a balanced diet,” she said. “There’s no such thing as a proper diet, but make sure you’re getting all of the nutrients you need, as well as getting active, moving, and staying engaged.”
The report was published online May 5 in the journal Neurology.
