The Mediterranean diet varies by country and region, so it has a range of definitions.
But in general, it’s high in vegetables, fruits, legumes, nuts, beans, cereals, grains, fish, and unsaturated fats such as olive oil. It usually includes a low intake of meat and dairy foods.
“We all know that [the] Mediterranean diet is good for health, but there are few studies focusing on the elderly,” said Marialaura Bonaccio, an epidemiologist at the Mediterranean Neurological Institute, IRCCS Neuromed, and first author of the study.
Ms Bonaccio and her colleagues set out to fill this gap in knowledge.
