    Should we all eat the Mediterranean way?

    The Mediterranean diet is rich in vegetables, pulses and olive oil and traditionally includes small amounts of fish and very little red meat. Thousands of studies back its health benefits. In fact, it's considered to be one of the most widely researched diets in the world. But why has this way of eating come to prominence over others? Marta Guasch-Ferre from the University of Copenhagen, Denmark explains what the Mediterranean diet is and how her Spanish roots have informed her work. Professor Sarah Tracy from the University of Oklahoma tells the story of the diet's roots, popularised by American scientist Ancel Keys in the 1950's. And Ruth asks, if this way of eating isn't familiar in your culture, can you still make use of the Mediterranean diet's principles to improve your health? Singapore based cardiologist Professor Huang Zijuan has been looking at the science behind Asian inspired food swaps that could offer the same health benefits. Plus public health expert Professor Pekka Puska explains how he used the work of Ancel Keys in the 1970's to help transform the life expectancy of Finnish men. He co-led the now world famous North Karelia project, after Keys' research revealed how the region in eastern Finland had the highest rates of blood cholesterol in the world.

    Food heroes and villains

    ***This programme contains conversations about disordered eating which some listeners may find upsetting*** Social media is awash with nutritional misinformation with foods often cast as superheroes or villains. So how can we separate fact from fiction? And how can we know what posts we can trust? Social media loves to portray some foods, like carbs, sugar and seed oils as villains, to be avoided at all costs.Other food groups like protein are often claimed to be food heroes and some social media influencers tell their followers to prioritise those foods and cut out others. Ruth Alexander looks at the truth of some of those claims and the impact it can have on those who believe them and end up restricting their diets as a result. Cecile Simmons tells Ruth how she "fell down the rabbit hole" and ended up cutting out dozens of foods in an attempt to cure a skin condition. Personal trainer and nutrition expert Michael Ulloa explains how he's made it his mission to fight food misinformation online. Plus Ruth hears from Dr Emily Denniss, registered public health nutritionist and lecturer at Deakin University in Australia, who has studied the spread of food misinformation on social media. And with the help of US based registered dietician Grace Derocha, Ruth separates food fact from food fiction.
