Blue zone cooking—a concept that journalist Dan Buettner developed from his reporting on centenarian populations—emphasizes cooking with simple, fresh ingredients and echoes themes of the well-known Mediterranean diet.

Visit these 'blue zones,' where people live the longest

Blue zones, a term coined in 2004 by National Geographic Fellow Dan Buettner, are regions in the world where people live the longest and healthiest lives. Researchers have identified a few key aspects defining the culture of these areas—physical activity, diet, purpose-driven lives, and more. Explore the top five blue zones from across the world here.

Blue zones are geographic locations, such as Sardinia, Italy, where there have appeared to be disproportionately high numbers of healthy agers, perhaps due to factors including genetics, diet, social connections, and more.

One biologist is leading the blue zone criticisms—both questioning the original recordkeeping for these purported longevity-prone locations and pointing to recent research showing declining numbers of healthy seniors in several official blue zone regions.

Watch the trailer for journalist Dan Buettner's popular Netflix documentary series 'Live to 100: Secrets of the Blue Zones,' which focuses on longevity insights from populations around the world.

Blue zones are regions with unusually high numbers of centenarians

Factors thought to contribute to longevity in these regions include diet and social connections, but their legitimacy is often questioned due to a lack of rigorous scientific methodology and potential record inaccuracies.

Dan Buettner, the journalist who popularized the term blue zones, fires back at criticisms of blue zones in this 2026 letter to the editor published by STAT News.

Most self-reported claims of exceptional longevity are exaggerated, but read how demographers verify age claims and why some of the original blue zone demographers say blue zone regions are real and worth studying.

Read the main paper criticizing the concept of blue zones, which argues recordkeeping errors, pension fraud, and natural disasters likely explain the high numbers of purported healthy centenarians in certain locations.

In the original 2004 blue zones study, which sought to verify the ages of long-lived, healthy populations in Sardinia, Italy, researchers hypothesized that inbreeding in these isolated communities may have helped promote their longevity.

Fort Worth, Texas, is the largest US blue zone area—a designation not from demographers but from journalist Dan Buettner's organization, which means Blue Zones LLC partnered with the city to help residents live healthier.

Health food broke into the mainstream by the 1980s

A 1984 New York Times story noted that Americans were eating less red meat than a decade prior, and that, in general, the country was “talking, thinking and worrying about what they eat to a degree unique in the nation's history.” The feature then details foods that were then considered bizarre: whole-grain muffins, hummus, and a variety of vegetarian dishes. (Some readers may experience a paywall.)

Some call Beard the original 'foodie'

James Beard came of age when home cooking revolved around canned and frozen ingredients. Likewise, West Coast cuisine wasn’t on anyone’s radar. Beard’s appreciation of fresh, seasonal ingredients and regional influences provided a foundation for today’s movement toward local, farm-to-table cooking and the foodies who seek it out.

Learn how colorectal cancer is linked to the American diet and chronic inflammation

A University of South Carolina colon cancer researcher offers insights from his own research and notes that more exercise, social support, and eating fruits, vegetables, legumes, and foods like fish and olive oil—often called the Mediterranean diet—are associated with better health—and could improve our colons.

The nutrients vegetarians and vegans need to keep in mind

Although most older Americans still enjoy their steaks and chicken, an estimated 2.5 million of those ages 55 and older have abandoned red meat and poultry in favor of a predominantly plant-based diet. Some people decide to go vegetarian or vegan...

The evolution of the human diet

Could eating like our ancestors make us healthier? One estimate suggests prehistoric hunter-gatherer communities obtained 75% of their calories from meat and fish.

What constitutes a 'healthy' diet?

A natural diet, typically high in plant-based foods and low in processed foods, appears to be the main contributor to a healthy, diverse gut microbiome.

'Diet for a Small Planet' popularized the vegetarian diet

Frances Moore Lappe’s 1971 book provided recipes for vegetarian dishes, introducing millions to soy, sprouts, and tofu. It also argued that a vegetarian diet was a political act that could solve world hunger by redirecting food from livestock to humans.

The formula behind super agers—those possessing health and cognitive skills of people decades younger

A study of about 1,400 super agers did not identify any underlying genetic mechanism for longevity. While researchers instead emphasized that sustainable habits involving positive social connections, sleep, mood, diet, exercise, and personal fulfillment help reduce long-term risks, there is no one-size-fits-all formula for everyone.

With Americans increasingly concerned about high grocery prices, experts suggest meal planning and using apps like TooGoodToGo to keep household food costs down.

How understanding a balanced diet can help you make good food choices

Eating a balanced diet—which includes a variety of foods from all food groups—is important for optimal health. It is also recommended to avoid ultra-processed foods, such as frozen meals, fast foods, soda, and flavored yogurt. The simplest way...

The quest to find natural ways to extend lifespan

Tales of searching for the Fountain of Youth persist. Our modern-day version is marked by promises of pharmaceutical miracles and a proliferation of viral "biohacking" routines. One doctor’s quest to unlock the keys to longevity stimulated much of this renewed fervor, though his ideas are often taken out of context.

Dave Asprey is considered one of the fathers of modern biohacking

Entrepreneur Dave Asprey wants to live longer than anyone else, a desire that's led him to biohacking. Asprey relies on supplements, stem cell treatments, rigid dieting, exercise, and more. The inventor of Bulletproof Coffee has no medical or nutritional training, though that's not unusual among biohacking's DIY experimenters.

Moving your body every day is key to longevity

In an era of biohacking, where millionaires subject themselves to draconian routines and tests to de-age themselves, one study suggests a super simple key predictor of mortality: more than any other trait, how much subjects moved determined how long they'd live. Movement mattered even more than age in predicting overall life longevity. Researchers suggest this means we should all simply get outside a bit more. Read more about the study here.

Understanding the biochemistry of ingredients and taste can improve flavor and texture

Keeping eggs at room temperature produces smoother batters when baking, and doing the same with tomatoes helps prevent a mealy, granular mouthfeel. Salting meat a day before gives more time for proteins to break down, improving flavor and tenderness, while cooking vegetables in well-salted water can lock in nutrients and color.

Iceberg lettuce was the salad staple people ate for most of the 20th century, popular due to its durability, long shelf life, and mild flavor.

Hippies explored the possibilities of organic food

The 1960s counterculture sought to buck traditions, including culinary ones. Hippies believed that healthier food was integral to dismantling the status quo and, in turn, started health food stores, espoused vegetarian diets, and cultivated organic food, which they found to be a welcome alternative to the over-commercialized farming industry. In the decades since the movement’s decline, many of its practices have been absorbed by the mainstream.

The term 'superfood' is a marketing construct with no scientific or medical definition

Encompassing at least 136 plants and animals, the concept has been criticized by nutritionists for its scientific value, which has been exploited by the wellness industry for profit. Although the label has encouraged the consumption of fruits and vegetables, food variety and minimal processing remain key to a healthy diet.

Biohacking to boost personal health has become a concept that encompasses everything from vitamin regimens and cryochambers to brain implants and red light therapy.

A quarter of Gen Z eats organic food

A 2025 YouGov poll found that 25% of Gen Z US adults eat organic food, while 10% say they follow a whole-foods diet, meaning they seek out foods that are minimally processed.

Multiple new research paths may lead to slowing (or even reversing) aging

Aging has always been inevitable, but fasting, epigenetic reprogramming, and parabiosis seem to help people stay young. By studying centenarians, memory, and even the humble roundworm, scientists are looking for the genetic basis to live not just a long life, but a healthy one.

How the Great Depression still shapes the way Americans eat

From fortified foods to nutrition labels, the legacy of an early financial crisis lives on in kitchens across the United States. Ethnic foods with their (supposedly) hunger-triggering spices were vilified and considered “stimulants” along the lines of caffeine and so, in their stead came prune puddings, canned-meat stews, and dairy-heavy vegetable casseroles featuring America’s first fortified foods. Read more here.

Building new supermarkets in food deserts likely won't help as much as nutrition education in closing healthy-eating gaps.

Ultraprocessed foods are linked with a 58% elevated risk of developing dementia.

Critics argue social media made 'foodie' culture increasingly superficial

For 40 years, being a "foodie" meant possessing knowledge and expertise about ingredients, restaurants, and flavors. Now, the author argues, being a foodie has more to do with documenting aesthetically pleasing meals than critical consumption. She argues for increased attention toward the complex systems that bring food to our tables.

Can humans delay or reverse old age?

We're not sure yet. Researchers at the University of California San Francisco are studying why some conditions and behaviors, such as low-oxygen environments and exercise, benefit the aging process, hoping to reveal potential health applications. Some of this research focuses on klotho, a naturally occurring age-regulating hormone named after the Greek Fate Clotho. Animal studies on klotho brain injections found subjects had improved memory recall and age-related degeneration resistance.

The benefits of sous vide: cooking food in bags immersed in water

Through this technique, food can be prepared to precise temperatures lower than those of open flames, without the risk of overcooking, with less oil, fat, and salt, and without requiring ongoing attention. By allowing for long cooking times, tougher cuts of meat can also be prepared at lower temperatures.

Can fasting help you live longer?

Animal studies into the health benefits of calorie restrictions of 20%-40% suggest it extends life spans and reduces incidents of age-related diseases, including cancer. This article explores the research into fasting, calorie restriction, and longevity.

What did the Vikings eat?

Examining a culture's culinary practices gives insight into its social structure, skills, and ideology. This article follows culinary archaeologist Daniel Serra as he explores the food habits and choices of Vikings. His findings have effectively ended "the myth of Vikings gnawing off the meat of the bones of wild animals," with evidence providing a clearer picture of Viking society as filled with farmers who didn't have time to hunt.

Gladiators followed a mostly vegetarian, high-calcium diet

Analysis of skeletons from a gladiator cemetery at Ephesus by researchers at the Medical University of Vienna found little meat consumption but unusually high calcium levels—likely from drinking wood ash mixed with water to promote weight gain and protect vital organs.

Should you eat an all-meat diet?

The carnivore diet is reportedly a way of eating inherited from human ancestors, a tale that has roots in anthropology's early days. This article explores the all-meat diet's ancestral claims and what happens if you cut vegetables and fruits from...

There's no specific anti-inflammatory diet, but certain foods increase the chance of inflammation

Research suggests humans can reduce inflammation by limiting foods that are already known to be unhealthy for the human body—because they alter gut bacteria and stress the immune system—such as highly-processed foods, deep fried foods, sugary drinks, trans fats, red meats, and foods made with white flour. Foods that help the body include fatty fish such as salmon, legumes, fruits, and vegetables.

Learn the history of food science breakthroughs from the 20th century

Long after humans developed the means to produce sufficient food to feed civilizations, scientific research focused on a wide variety of objectives, such as developing methods to preserve food quality (accomplished via frozen food), speeding up cooking (leading to the microwave), and lowering the cost of sweetening food, which high fructose corn syrup provides.

The Whole Earth Catalog offered readers tools for healthy eating

The publication promised hippies "access to tools"—listings for "high quality or low cost" books, devices, and instructions for alternative living, including cultivating natural and organic foods. This archive comprises high-definition scans of nearly all materials published between 1968 and 2002.

Super-agers: seniors 80 and above with the memory ability of people in their 50s

Studies show the number one indicator of whether someone is a "super-ager" is not diet or genetics, but the extent of their social relationships. Moreover, scans reveal noticeable physical differences in certain parts of the brain in patients with extensive social networks.

Famous Catalan dishes

Catalan cuisine is defined by its bold and unexpected flavor combinations, which are largely a reflection of Catalonia’s diverse geography. Meat and seafood are often combined into a single dish, an ode to the region’s fertile soil and coastline. Meatballs with cuttlefish and peas is a common meal enjoyed alongside fresh bread. Salivate over 15 more dishes in this listicle that’s frontloaded with a bit of history.

Doctors shift focus from extending lifespan to lengthening health span

As scientific advances extend the average human lifespan, many are turning their attention toward extending "health span." Health span refers to the number of years one is active and disease-free. The ultimate goal is to extend one’s health span to match one’s lifespan.
