Did you know that Mediterranean food is the fastest growing segment in the food industry? People who follow a Mediterranean diet are likely to be happier in life. This is the conclusion of a new report published in the journal ‘Archives of General Psychiatry’. The study’s authors say a diet that is rich in vegetables, fruits, nuts, whole grains and fish seems to make people less likely to develop depression. This may explain why people who live in Mediterranean countries are more laid back than other Europeans. There are fewer mental disorders in Mediterranean countries and scientists believe this could be because of the diet. The new research supports previous studies that suggested olive oil protects against depression. No Greek meal is complete without olive oil.
