The secret to living to 100 may not be found in green powders or pricey supplements, but in how often meat actually appears on your plate.
Longevity expert Dan Buettner has revealed that people in the world’s longest-living communities don’t cut meat out entirely, and instead they simply stop building every meal around it.
The 64-year-old National Geographic Fellow and bestselling author has spent decades travelling the globe studying so-called Blue Zones – regions where people routinely live well into their 90s and beyond.
And despite assumptions that these populations are strictly plant-based, Buettner says most aren’t vegan at all.
The five original ‘Blue Zones’ are regions with the highest concentrations of centenarians and longest-lived people and hold many secrets to ageing well.
Cities like Okinawa in Japan, Sardinia in Italy, Nicoya Peninsula in Costa Rica, Ikaria in Greece, and Loma Linda in California, USA all count.
These areas share common lifestyle factors, including plant-based diets, strong social networks, and natural daily movement.
‘You don’t have to be vegan to live a long life,’ he explained in a recent video to his 800,000 followers.

What researchers do know, he said, is that eating meat too frequently significantly increases the risk of chronic disease. ‘If you’re eating more than, say, one serving a day, you’re raising your chances of chronic disease’
‘In fact, most people in Blue Zones are not vegan but we don’t know the safe level of meat.’
What researchers do know, he said, is that eating meat too frequently significantly increases the risk of chronic disease.
‘If you’re eating more than, say, one serving a day, you’re raising your chances of chronic disease.’
In contrast, meat plays a far smaller role in Blue Zone diets, with people in those zones only eating meat once per week, with meals instead centred around vegetables, beans, whole grains and healthy fats.
Rather than banning meat altogether, his message is more about moderation and shifting it from the star of the plate to an occasional addition.
‘The general rule he applies to his own life if ‘the less meat you can eat and maintain your health, the better off you’ll be.’
Practising what he preaches, Dan insists the key to his health and longevity starts with a breakfast bowl of Sardinian minestrone soup filled to the brim with vegetables, beans, olive oil and avocado.
Come lunchtime, he avoids rigid dieting. Instead, he reaches for whatever fruit appeals to him that day.

Should meat be a rare treat or a daily staple for a healthy, long life?
Dan is not fully vegan, but does credit a humble bowl of Sardinian minestrone soup as his secret to longevity, which he has as his daily breakfast. It consists of vegetable soup, beans, olive oil and topped with avocado for lasting energy
‘I usually let myself eat as much fruit as I want, and I eat the food that appeals to me that day because then I’ll keep eating it,’ he said.
Minestrone has been a staple of Italian cuisine dating back to the days of ancient Rome, traditionally made with whatever vegetables were available and often simmered for hours to develop its rich, savoury flavour.
But in Sardinia’s mountainous interior, it’s more than just a cheap, warming meal.
Families have eaten variations of the soup daily for centuries, pairing beans, vegetables and grains in ways that modern nutritional science now recognises as a blueprint for exceptional health.
Dan’s extensive research across global Blue Zones has revealed that diets rich in legumes, greens and unrefined carbohydrates are strongly linked to reduced chronic disease, lower inflammation and significantly longer lifespan.
It forms part of the wider culinary traditions documented in his best-selling book The Blue Zones Kitchen, which pairs scientific reporting with more than 100 traditional longevity recipes.
Dan has warned that many of these eating habits are disappearing as Western fast food culture spreads, making it more important than ever to preserve the meals that have helped entire populations thrive for generations.
One viewer praised his refreshingly gentle approach, calling his philosophy ‘a great reminder that longevity isn’t built on extremes’, but rather repeatable habits, real food, and ‘meaningful connection.’
Despite being the face of global health and longevity, Dan happily admitted he goes out for dinner every single night, as he finds connection just as important as nutrition.
‘I eat mostly a whole food, plant-based diet, but I also know being connected socially is part of that cluster of factors that leads to 100,’ he explained.
Followers loved the sentiment, with one commenting: ‘I love that you said being part of the social portion of the dining is important.’
