Researchers are studying the residents of the island of Ikaria to figure out why so many of them live well into their 90s and beyond:
Following the report by Pes and Poulain, Dr. Christina Chrysohoou, a cardiologist at the University of Athens School of Medicine, teamed up with half a dozen scientists to organize the Ikaria Study, which includes a survey of the diet of 673 Ikarians. She found that her subjects consumed about six times as many beans a day as Americans, ate fish twice a week and meat five times a month, drank on average two to three cups of coffee a day and took in about a quarter as much refined sugar — the elderly did not like soda. She also discovered they were consuming high levels of olive oil along with two to four glasses of wine a day.
Chrysohoou also suspected that Ikarians’ sleep and sex habits might have something to do with their long life. She cited a 2008 paper by the University of Athens Medical School and the Harvard School of Public Health that studied more than 23,000 Greek adults. The researchers followed subjects for an average of six years, measuring their diets, physical activity and how much they napped. They found that occasional napping was associated with a 12 percent reduction in the risk of coronary heart disease, but that regular napping — at least three days weekly — was associated with a 37 percent reduction. She also pointed out a preliminary study of Ikarian men between 65 and 100 that included the fact that 80 percent of them claimed to have sex regularly, and a quarter of that self-reported group said they were doing so with ‘good duration’ and ‘achievement.’
