Pioppi, in southern Italy, has been dubbed the ‘world’s healthiest village’, with its residents frequently living 10 years longer than elsewhere to 100 years old. Despite bacon and chocolate being a staple of their diet, its inhabitants’ love of vegetables, oily fish and nuts is thought to prevent them from developing heart disease or type 2 diabetes. As well as consuming lots of olive oil for its heart-health benefits, residents also start each day with a tablespoon of apple cider vinegar, which is thought to aid acid reflux, lower blood pressure and boost weight loss. The Pioppi diet also includes eggs most days, which are a good source of protein for keeping hunger pangs at bay. It also recommends intermittent fasting by limiting your ‘eating window’ to just eight-to-nine hours a day. Red wine is permitted providing it is good quality.
