Lately, the Paleo food plan has gained recognition for its emphasis on consuming meals that our ancestors might need eaten. This dietary sample excludes processed meals, dairy, grains, beans, and different meals developed after the Paleolithic period.
Whereas followers of the Paleo—or Caveman—food plan interpret its tips in another way, many appear to emphasise consuming meat and fish as their major protein sources.
Nevertheless, a research led by a College of Wyoming archaeologist challenges the traditional knowledge surrounding Paleo diets and attracts intriguing parallels between Paleo eaters and the long-lived Blue Zone communities.

Archaeologists lengthy believed that early human diets have been primarily meat-based. Nevertheless, Assistant Professor Randy Haas’ evaluation of the stays of 24 people from the Wilamaya Patjxa and Soro Mik’aya Patjxa burial websites in Peru paints a unique image.
Are Paleo diets plant-based?
The research, revealed by the peer-reviewed journal Plos One, applies strategies in isotope chemistry and statistical modeling to unveil a shocking twist in early Andean societies and conventional hunter-gatherer narratives.
“Typical knowledge holds that early human economies targeted on searching—an concept that has led to various high-protein dietary fads such because the Paleo food plan,” Haas mentioned in a press release.
“Our evaluation reveals that the diets have been composed of 80-percent plant matter and 20-percent meat,” Hass mentioned.
For these early people of the Andes, spanning from 9,000 to six,500 years in the past, there’s certainly proof that searching of huge mammals offered a few of their diets. Nevertheless, the brand new evaluation of the isotopic composition of the human bones reveals that plant meals made up the vast majority of particular person diets, with meat enjoying a secondary function.
Burnt plant stays from the websites and distinct dental-wear patterns on the people’ higher incisors point out that tubers, akin to potatoes, doubtless have been probably the most outstanding subsistence useful resource.

“Our mixture of isotope chemistry, paleoethnobotanical, and zooarchaeological strategies presents the clearest and most correct image of early Andean diets so far,” Haas mentioned. “These findings replace our understanding of earliest forager economies and the pathway to agricultural economies within the Andean highlands.”
Paleo versus Blue Zones: consuming for longevity
Trendy interpretations of historical diets usually favor meat-centric approaches, primarily based on the belief that it aligns with our evolutionary previous. Nevertheless, the brand new research from the Andes questions this notion, emphasizing the potential advantages of a plant-rich food plan throughout Paleo instances.
As an alternative, the dietary patterns of our ancestors appear extra aligned with folks residing in Blue Zones, the place the main target is on plant meals. Lately, the Mediterranean food plan has been the topic of many research, which level to its correlation to decrease illness dangers and longer lifespans.

In a single research analyzing the habits of greater than 110,000 folks, following a Mediterranean life-style diminished the chance of all-cause mortality by 29 % and most cancers mortality by 28 %.
Blue Zoners are additionally recognized for getting a lot of their protein from beans and legumes. Nevertheless, these plant meals are prohibited in Paleo diets as a result of excessive content material of lectins and phytic acids. What does the analysis say?
In a single 2022 research, researchers discovered that substituting a portion of meat with both beans and peas or potatoes contributed to weight reduction. This research builds upon earlier analysis that established a connection between the consumption of beans and peas and enhanced blood glucose management amongst people newly identified with sort 2 diabetes.
The truth is, the Melis Household of Sardinia—often called “the longest-living household on the earth”—is understood for consuming a chickpea-filled minestrone a number of instances per day. On this Blue Zone, fava beans and different legumes are an on a regular basis staple.
Extra research about this plant-forward method of consuming have proven advantages that vary from improved mind well being and slower cognitive decline to decrease incidence of fatty liver illness and extra.

This matter was additionally explored within the widespread Netflix documentary, Stay to 100: Secrets and techniques of the Blue Zones, which underlines the core components of longevity: pure motion, reasonable alcohol consumption, minimal power stress, and predominantly plant-based diets.
These findings, mixed with the analysis within the Andes, are placing cracks in the concept our evolutionary historical past revolved round meat consumption.
“On condition that archaeological biases have lengthy misled archaeologists—myself included—within the Andes, it’s doubtless that future isotopic analysis in different elements of the world will equally present that archaeologists have additionally gotten it incorrect elsewhere,” Chen mentioned.
