Senior author Dr Mary Yannakoulia, said, 'The term Mediterranean diet is widely used to describe a dietary pattern characterised by the abundance of plant foods: fruits, vegetables, cereals, legumes, nuts, and seeds.
'Olive oil is the principal source of fat.
'A Mediterranean diet also includes moderate amounts of dairy products, low to moderate amounts of fish and poultry, red meat in low amounts, and wine, consumed modestly.
'We need to further explore the mechanisms that link this healthful pattern with better sleep habits, thus promoting quality of life of older people,' she added.
Mediterranean diet is a traditional diet from Mediterranean countries, characterised especially by a high consumption of vegetables and olive oil and moderate consumption of protein, and thought to confer health benefits.
