(CNN) - The Mediterranean diet has been linked to stronger bones, a healthier heart and a longer life.
Now you can add lowering your risk of dementia to the growing list of benefits.
That's according to new research presented at the Alzheimer's Association international conference.
It shows healthy older adults who follow the Mediterranean or similar diets lower risk of dementia by a third.
The Mediterranean diet is simple: plant-based cooking, with the majority of each meal focused on fruits, vegetables, whole grains and an emphasis on olive oil.
Not on the diet? Sugar, flour and most fats.
Meat makes a rare appearance, but usually only to flavor a dish.
Instead, use eggs and dairy. But make sure the portions are small.
Research connecting the Mediterranean diet to a lower rate of dementia is observational, meaning it is based on people reporting what they eat.
Researchers say clinical trials are needed to prove the connection between diet and dementia.
