According to a new research, Mediterranean Diet alters the gut microbiome of elderly people improving their health status and longevity.

A new study published on the BMJ Journal Gut found that being on Mediterranean Diet for one year can alter the microbiome of elderly people avoiding production of inflammatory chemicals and improving brain function.

The study analyzed the gut microbiome of 612 elderly people from France, Italy, the Netherlands, Poland, and the United Kingdom before putting 323 of them on a special diet for a year, following the mediterranean principles of eating mainly fruits, vegetables, nuts, legumes, olive oil and fish and little red meat, sugar and saturated fats.

At the end of the year, researchers found out that those people who had adopted Mediterranean Diet experienced beneficial changes to the microbiome in their digestive system. Mediterranean Diet helped them maintain their bacterial diversity and prevent inflammations, leading to a general improvement of their health status and longevity.
