Dan Buettner believes that "when a ritual lasts for hundreds or thousands of years, like prayer before a meal, it serves some purpose". Dan is the best-selling author of and founder of The Blue Zones; five parts of the world where people tend to live much longer and healthier lives, many into their hundreds. In this programme, Leyla Kazim finds out more about the culinary aspects of his research, discovering what is eaten in the Blue Zones, what isn't being eaten, and some of the practices that exist around meal times.

She also meets two academics whose work focuses on how to help people living in the UK live longer and more healthily. Liz Williams from the Healthy Lifespan Institute at the University of Sheffield explains that although the current life expectancy for people in the UK is just over 81 years - our average 'healthy life' expectancy is much lower, at around 63. Dr Oliver Shannon from The University of Newcastle explains how some of the Blue Zones observational findings are consistent with research they have been doing into the impact of the Mediterranean diet on brain health.

The promise of a long healthy life is all well and good - but as we know the reality of diets is that they are impossibly hard to keep to. So could choosing to make a 'lifestyle' change be any easier to stick with? Leyla hears from Jean Newton who in her 70s has done just that.
