Dan Buettner he is a best-selling author, explorer, communicator, producer and researcher. For years and years he has studied and analyzed the diet of the ultracentenarians who live in the so-called “Blue Zones“, those areas of the world where life expectancy is surprisingly high. Some examples are the prefecture of Okinawa in Japan, the province of Nuoro in Sardinia, the Greece and the peninsula of Nicoya in Costa Rica.
His research allowed him to identify two foods in particular, present in all supermarkets and at a low cost, to be introduced into your daily diet to extend your life: a can of beans and a handful of nuts. Then, he explained what their positive effects are.
Nuts and beans: the benefits
Dan Buettner notes that both beans and nuts contain a large amount of fiber, which is shown to reduce inflammation in the intestine and reduce the risk of life-threatening diseases, including cancer. Furthermore, they are rich in proteins and therefore help you feel full.
Furthermore, walnuts are one of the main sources of linoleic and Omega 3 fatty acids, generally linked to a reduction in the risk of contracting heart disease and, consequently, the possibility of living longer. Then, Dan specified that when it comes to longevity «there is no short-term solution. We need to accumulate a series of good habits to carry forward for decades.”
As for beans, a 2004 study of hundreds of elderly Blue Zone residents found that those who consumed the most beans lived longer and there was a 7% reduction in mortality risk for every 20 grams eaten, according to what the DailyMail reports. In Sardinia, in fact, chickpeas and broad beans are consumed, often every day, and in Costa Rica black beans.
