Mediterranean diet aids heart but strains wallet
Eating a Mediterranean diet rich in fish, olive oil, legumes, fruit and vegetables may strengthen the heart but the cost strains the wallet and may deter healthy eating, according to Spanish researchers. 
A study by the Department of Preventive Medicine and Public Health at the University of Navarra looked at the costs of Mediterranean and Western diets in more than 11,000 Spanish university graduates with a similar level of income.
