A study done in Greece says people can live longer and healthier lives if they eat what is known as the Mediterranean diet. Such a diet generally gets about 40 percent of its calories from olive oil and other fats that are considered healthy. Researchers from the University of Athens and Harvard University Medical School in Boston, Massachusetts did the study. They published the results in the New England Journal of Medicine. Researchers say it is all the foods together in the Mediterranean diet that make the difference. So they say people should eat a lot of fruits, vegetables, beans and fish. And they should use olive oil in their cooking.
