Bone Broth: An Ancient Superfood
PART I: THE ANCIENT STORY
The Most Primal Food
Bone broth may be trendy now, but it represents one of humanity's oldest and most resourceful foods. Long before we had grocery stores, restaurants, or even agriculture, our ancestors were cracking bones and simmering them to extract every possible nutrient. This practice likely stretches back hundreds of thousands of years, born from necessity and refined through generations of culinary wisdom.
Learning from the Scavengers
Interestingly, humans weren't the first to discover the nutritional treasure hidden inside bones. Vultures, particularly bearded vultures (lammergeiers), have perfected the art of accessing bone marrow. These remarkable birds get up to 90% of their diet from bone marrow and have developed an ingenious technique: they carry bones high into the sky and drop them from heights equivalent to the Statue of Liberty (around 300 feet or more) onto rocky surfaces below. The impact shatters the bones, revealing the rich, fatty marrow inside.
Our ancient ancestors may have observed similar behavior in nature, or perhaps they simply discovered through trial and error that bones contained something valuable. Either way, the quest for marrow became a defining characteristic of early human evolution.
Archaeological Evidence: The African Origins
The earliest definitive evidence of humans accessing bone marrow dates back approximately 400,000 years, though some researchers suggest the practice could be even older. Archaeological sites across Africa, particularly in East Africa where human evolution accelerated, show clear signs of systematic bone processing. Ancient bones bear distinctive percussion marks where our ancestors struck them with stone tools to crack them open and extract the marrow.
In places like Olduvai Gorge in Tanzania and sites throughout the East African Rift Valley, researchers have found collections of animal bones with telltale signs of marrow extraction. These weren't random acts but deliberate, skilled processing of carcasses to maximize nutrition.
Why Marrow Mattered
Bone marrow is extraordinarily nutrient-dense, containing high-quality fats, proteins, vitamins, and minerals. For early humans living in challenging environments, marrow represented a concentrated energy source that could mean the difference between survival and starvation. Unlike muscle meat, which other predators and scavengers consumed first, marrow remained protected inside bones, essentially a time-locked package of nutrition that patient, tool-using humans could access after other animals had moved on.
This access to marrow and other nutrient-dense animal foods likely played a crucial role in human brain development. Our brains are metabolically expensive organs, requiring substantial energy and specific nutrients to grow and function. The fats and nutrients in bone marrow provided exactly what growing human brains needed.
From Marrow to Broth: The Pottery Question
The leap from eating raw marrow to making bone broth required one critical innovation: cooking vessels. For most of human history, our ancestors couldn't make broth because they lacked watertight containers that could withstand fire. They could roast bones in fire and crack them open for marrow, but boiling required pottery or other heat-resistant vessels.
The earliest pottery currently known to archaeology comes from China, dating to around 20,000 years ago, with sites in southern China yielding pottery fragments from this period. Japan also has very early pottery (Jomon pottery) dating to around 16,000-14,000 years ago. Pottery appears much later in other regions: the Middle East around 10,000-9,000 years ago, sub-Saharan Africa around 9,000-10,000 years ago, South America around 7,000-8,000 years ago, and Europe around 6,000-7,000 years ago.
However, these dates tell us more about what has survived than what actually existed. This is a crucial distinction.
The Preservation Bias
Archaeological evidence is not a neutral record of the past. It's heavily biased toward what survives, and survival depends enormously on environmental conditions. This creates a significant problem when trying to understand early African innovations, despite Africa being the birthplace of humanity.
Why Africa's archaeological record is incomplete:
The very regions where humans evolved and spent most of their history - tropical and subtropical Africa - have some of the worst preservation conditions on Earth. High heat and humidity, heavy seasonal rains, and acidic soils rapidly break down organic materials and even fired pottery. The East African Rift Valley, humanity's cradle, is geologically active with volcanic activity, earthquakes, and intense erosion constantly destroying or deeply burying ancient sites. Dense vegetation hides sites and aggressive root systems break artifacts apart over time.
Why China's pottery survived:
Many of China's early pottery finds come from limestone caves, which are nearly ideal preservation environments, protected from weather and temperature extremes. Parts of northern China have much drier climates that preserve artifacts far better than tropical conditions. China also has thick deposits of wind-blown loess soil that gently buried and protected artifacts. These preservation advantages don't mean China invented pottery first; they mean Chinese pottery was more likely to survive 20,000 years.
The Deep Dive: Rethinking the Timeline
Let's do a deep dive here for a moment, because the timing matters more than we might think.
Consider this: the oldest pottery we know of - those Chinese fragments preserved under nearly ideal conditions in limestone caves - wasn't even scientifically recognized and dated until 2012. That's how recent our understanding is. And those fragments survived only because of exceptional preservation circumstances that simply don't exist in tropical Africa.
Now consider the timeline: humans were systematically processing bones for marrow in Africa for 400,000 years before our species spread worldwide. Four hundred thousand years. That's not just a long time - it's an immense span of human innovation, adaptation, and cultural development. During those millennia, humans mastered fire, developed sophisticated tool-making, created complex social structures, and developed the cognitive capacity for symbolic thought and language.
Given this vast timeline and demonstrated ingenuity, it seems far more likely than not that Africans found ways to make bone broth long before pottery was invented anywhere, or that pottery was invented in Africa much earlier than surviving evidence can prove. The human drive to extract maximum nutrition from available resources is universal and ancient. Watching fat and nutrients dissolve into water from heated bones would have been obvious to anyone who had both fire and water. The question isn't whether early Africans could have made bone broth, but rather how they did it and why the evidence hasn't survived those hundreds of thousands of years in harsh preservation conditions.
If pottery was indeed invented independently in China around 20,000 years ago, we should also consider the rich network of trade routes and cultural exchange that existed throughout human history. The Middle East sat at a crucial crossroads between Africa and Asia, serving as a bridge for ideas, technologies, and innovations flowing in all directions. These weren't isolated populations developing in bubbles - they were connected through trade, migration, and the natural human tendency to share useful knowledge. A revolutionary technology like pottery, or the practice of making bone broth, would have spread along these ancient networks of human connection.
The reality is that bone broth making - the practice of using hot water to extract nutrients from bones - could be vastly older than any pottery that's survived. It might stretch back not 20,000 years, but potentially 100,000 years or more, deep into that 400,000-year period when African humans were already sophisticated bone processors. This practice may sit at the very heart of the revolution in human nutrition and development that eventually enabled us to spread across the entire planet.
Ancient Cooking Methods: What the Evidence Shows
Consider the alternatives to pottery that ingenious cooks might have used - and here's the crucial point: we know these methods worked because they're documented archaeologically and many are still used in traditional cultures today.
Stone boiling is one of the most widespread ancient cooking methods. Heated stones are placed in a fire until glowing hot, then transferred using forked sticks into water-filled containers. The technique has been archaeologically dated to at least 4,800 years ago in North America, but became especially prominent between 250 CE and 1750 CE. Baskets woven tightly enough and sealed with tree resins, plant gums, or animal fats could hold water and withstand repeated heating from hot stones without burning through. This method is still used today in various forms: in India, tribal communities cook fish on hot stone slabs between layers of leaves; in Ladakh, traditional sourdough bread is cooked on heated stone; in Peru, the traditional pachamanca uses red-hot volcanic rocks in underground ovens.
Animal stomachs, bladders, and hides, properly prepared, made excellent watertight cooking vessels. Native Americans used bison stomachs and hides extensively for stone boiling, sometimes lining ground pits with hides to hold water. Scottish haggis, still made today, cooks meat and oatmeal inside a sheep's stomach. These organic vessels leave virtually no archaeological trace, yet they were sophisticated cooking technology.
Bark containers and wooden vessels were used across many cultures. Indigenous peoples in eastern Canada and the Northwest Coast used bark baskets and bark containers for stone boiling, with bark baskets preferred because they didn't burn as easily. Small canoes were even used as cooking containers on the Northwest Coast for preparing whale fat.
Ground ovens and cooking pits represent another ancient method. Plains peoples dug below-ground boiling pits lined with animal hides because wind cooled above-ground containers too quickly. Earth ovens involve digging pits, heating stones thoroughly, layering food wrapped in leaves with hot stones, then covering everything with earth to trap heat for slow cooking over several hours.
Large shells in coastal areas could serve as small cooking containers. Bamboo segments, where available, could be used for boiling. Hollowed-out gourds could withstand gentle heating.
None of these materials preserve well in tropical African conditions. A leather cooking vessel, a woven basket, or a gourd container used 50,000 years ago in East Africa would leave virtually no trace today. Yet we know from worldwide ethnographic evidence that all were well within the technical capabilities of early humans - because people still use variations of these methods today, thousands of years later.
The Global Pattern: Convergent Technology
Understanding how far back these cooking traditions go in cultures worldwide helps us grasp the upper limits for when these ideas could have developed and spread. The timeline reveals something remarkable:
Aboriginal Australians have continuously occupied their continent for 50,000 to 65,000 years, making them among the oldest continuous cultures on Earth. They cooked in bark containers and used hot stones in ground ovens throughout this immense span of time. Their isolation for tens of thousands of years means they developed these methods independently.
Native Americans have been present in North and South America for 15,000 to 30,000 years. Stone boiling has been archaeologically documented at 4,800 years ago in the Northern Plains, becoming especially prominent between 250 CE and 1750 CE. Given their arrival date and the sophistication of their techniques, the practice likely extends much further back.
South American peoples have practiced the pachamanca tradition (earth oven with hot stones) for approximately 5,000 years, predating the Inca civilization. This represents an unbroken tradition stretching back to when the great pyramids of Egypt were being built.
Indian tribal communities continue using hot stone cooking methods today, part of cultural lineages extending back thousands of years across the Asian subcontinent.
What this pattern reveals:
These geographically isolated populations - Aboriginal Australians separated by ocean for 50,000+ years, Native Americans who arrived via land bridge 15,000-30,000 years ago, South Americans, and various Asian populations - ALL independently developed hot stone cooking and similar boiling methods. This isn't one invention spreading globally through trade routes. This is convergent technology: different people in different places, separated by vast distances and time, solving the same problem (how to boil water without pottery) in remarkably similar ways.
This convergent development tells us something profound: these methods are so intuitive, so obviously effective when you have stones, fire, and containers, that humans figured them out repeatedly across the globe. If isolated populations on every inhabited continent discovered stone boiling independently, then sophisticated African humans - with 400,000 years of bone processing experience, mastery of fire, and advanced cognitive abilities - almost certainly discovered it first, and likely much earlier than any other population.
The fact that many cultures preserved these traditions into modern times, continuing to use them even after pottery and metal vessels became available, demonstrates these weren't crude stopgaps or primitive technologies. They were effective, reliable, proven methods that worked so well that some cultures saw no reason to abandon them. When Indian tribal communities today still cook fish on hot stones between leaves, or Peruvian families gather for traditional pachamanca feasts, they're using technologies that may be tens of thousands of years old - technologies that quite possibly originated in Africa long before spreading or being independently rediscovered across the world.
We must read the archaeological record with humility, understanding that it shows us only the durable fragments of past human ingenuity, not its full scope. The story of bone broth almost certainly begins in Africa, even if the proof lies buried beyond recovery or dissolved into the African soil long ago.
PART II: TRADITIONAL WISDOM WORLDWIDE
A Universal Discovery
Across virtually every traditional culture worldwide, bone broth appears as a foundational food. This isn't coincidence but convergent wisdom. From Jewish chicken soup to Vietnamese pho, from Korean seolleongtang to Chinese bone broths used in traditional medicine, cultures independently discovered that slowly simmered bones produced liquid gold.
Traditional healers and grandmothers didn't know the scientific terms for collagen, glycine, or glucosamine, but they knew bone broth healed the sick, strengthened the weak, and nourished growing children. In traditional Chinese medicine, bone broth builds qi (life energy) and strengthens the blood. In European folk medicine, it was prescribed for everything from digestive ailments to joint problems. Modern science is now confirming what these cultures knew intuitively.
PART III: THE SCIENCE & NUTRITION
Water: The Extraordinary Vessel
Let's do a deep dive here for a moment, because I think this is crucial: our bodies have been expecting bone broth for potentially hundreds of thousands of years. This isn't just another trendy superfood. This is something our digestive systems evolved alongside, something they know how to use.
Think about it. Water is an extraordinary solvent and carrier of nutrients. There's ancient wisdom in that line from Disney's Frozen where the snowman says "water has memory." This isn't just poetic - it's chemically accurate. Water literally holds onto what it comes into contact with, preserving a history, a documented evidence of everything that water has touched.
Consider what happens when you add a single drop of black dye to a glass of water. That dye dissolves at the molecular level, becoming part of the water's composition. You cannot filter it out. You cannot remove it by any ordinary means. Your only option is dilution - not removing the dye, but replacing the water. The water holds that dye, carries it, remembers it. This is what we mean by water's memory: its profound capacity to incorporate and preserve what passes through it.
When we heat water with bones, leaves, or coffee beans, water does something remarkable. It doesn't just touch these materials - it actively pulls compounds out at the molecular level and holds them. Fat-soluble compounds, water-soluble vitamins, minerals that leach from bones, aromatic oils, proteins that break down into amino acids, collagen that becomes gelatin - all of these dissolve into the water and become part of its composition. The water becomes a living record, a historical document of everything it extracted. This is how tea works. How coffee works. How bone broth works.
This is why tea works. Why coffee works. Why bone broth works. Hot water doesn't just mix with these materials; it actively pulls nutrients out and holds them in suspension or solution, making them bioavailable to our bodies in ways that eating the raw material alone wouldn't accomplish. Our ancestors who figured out how to use hot water as an extraction medium unlocked a revolution in nutrition.
When you drink bone broth, you're not asking your body to do something novel or strange. You're giving it something it has sophisticated mechanisms to process, absorb, and use. Your gut lining recognizes these nutrients. Your cells know what to do with them. This is food your body has instructions for.
What Happens When Bones Simmer
When bones simmer for hours, several remarkable things happen:
Collagen breaks down into gelatin, which gives properly made bone broth its characteristic gel-like consistency when cold. This gelatin supports gut health, helps heal the intestinal lining, and provides the building blocks for healthy skin, hair, nails, and joints.
Minerals leach from the bones into the broth in bioavailable forms. Calcium, magnesium, phosphorus, potassium, and trace minerals become suspended in the liquid, ready for your body to absorb. The addition of acidic ingredients like vinegar or lemon juice enhances this mineral extraction.
Amino acids concentrate in the broth, particularly glycine, proline, and glutamine. Glycine supports detoxification and acts as a calming neurotransmitter. Proline helps repair tissue and supports cardiovascular health. Glutamine is crucial for gut health and immune function.
Glucosamine and chondroitin extracted from cartilage and connective tissue support joint health. These are the same compounds sold as expensive supplements, but in bone broth they come packaged with cofactors that aid absorption.
Healthy fats from marrow provide energy and support hormone production, brain function, and the absorption of fat-soluble vitamins.
PART IV: PRACTICAL BENEFITS
Benefits for Children
For growing children, bone broth offers exceptional nutritional support. The minerals support bone development and tooth formation. The amino acids fuel rapid growth and tissue development. The easily digestible nature of bone broth means even young digestive systems can access these nutrients efficiently.
Children's bodies are constantly building new tissue, and bone broth provides the raw materials they need. The gelatin supports a healthy gut lining, which is crucial since about 70% of the immune system resides in the gut. Many parents notice their children have fewer illnesses and recover faster when bone broth is a regular part of their diet.
For picky eaters or children going through phases of poor appetite, bone broth can be a nutritional safety net. Even small amounts provide concentrated nutrition. It can be sipped plain, used as a base for sauces, or incorporated into meals in ways children don't even notice.
The Sick Room Staple
The tradition of feeding chicken soup to sick people isn't just comfort; it's medicine. When illness strikes, especially respiratory or digestive illness, bone broth provides:
Hydration with electrolytes that plain water lacks
Easy nutrition that doesn't tax a struggling digestive system
Anti-inflammatory compounds that help reduce swelling and congestion
Immune support through amino acids and minerals that fuel immune cell production
Warmth and steam that help clear congestion and soothe irritated throats
Modern research has confirmed that chicken soup specifically has mild anti-inflammatory effects and can help slow the movement of neutrophils (white blood cells) in the body, potentially reducing upper respiratory symptoms.
PART V: MAKING CHOICES
Chicken vs. Beef: Choosing Your Broth
Both chicken and beef bone broth offer excellent nutrition, but with some differences:
Chicken bone broth tends to be lighter in flavor and color, making it more versatile in cooking and more acceptable to children and sensitive palates. It's rich in collagen, minerals, and amino acids but generally has a shorter cooking time (4-8 hours). The milder flavor makes it ideal for sipping plain or using in virtually any recipe.
Beef bone broth, especially when made with marrow bones, knuckle bones, and joints, is richer and more intensely flavored. It contains more minerals, particularly when made with marrow-rich bones. The longer cooking time (12-24 hours) extracts maximum nutrients. Some find the flavor too strong for plain sipping, but it makes an incredibly rich base for stews and sauces.
For children just starting with bone broth, chicken is usually the better introduction. As palates mature, beef broth offers additional benefits.
The Quality Question: Why Organic and Pasture-Raised Matters
When making bone broth, quality matters more than with almost any other food. You're not just eating the meat; you're extracting and concentrating everything from the bones, including anything the animal was exposed to during its life.
Conventionally raised animals may have been given antibiotics, hormones, and fed grain-based diets that alter their nutritional profile. They may have been raised in confined conditions with less access to natural movement and sunlight. All of this affects what ends up in their bones and ultimately in your broth.
Organic, pasture-raised animals have several advantages:
They consume their natural diet (grass for cattle, insects and plants for chickens), which improves their nutritional profile. Pasture-raised animals have higher levels of omega-3 fatty acids and fat-soluble vitamins like A and K2.
They move naturally and develop stronger bones with better mineral density, meaning more nutrition for your broth.
They aren't given routine antibiotics or synthetic hormones, so you're not concentrating these substances in your broth.
They're raised in more humane conditions with access to fresh air and sunlight, factors that affect animal health and therefore the quality of their tissues.
When you simmer bones for hours, you're creating a concentrated extract. Quality ingredients become concentrated quality nutrition. Questionable ingredients become concentrated concerns. For a food you might feed daily to your children or consume regularly yourself, choosing the best quality bones available is a worthwhile investment in health.
A Food for All Times
From the African savanna hundreds of thousands of years ago to modern kitchens today, bone broth represents continuity with our ancestral past. It embodies resourcefulness: waste nothing, use everything, and extract maximum nutrition from available food. It connects us to traditional wisdom while modern science validates what grandmothers always knew.
In our current era of processed foods and nutritional confusion, bone broth offers simplicity: real food, prepared traditionally, nourishing deeply. Whether you're feeding growing children, recovering from illness, supporting athletic performance, or simply seeking optimal nutrition, this ancient food remains remarkably relevant.
The next time you simmer a pot of bones, remember you're participating in one of humanity's oldest culinary traditions, one that quite literally helped make us who we are today.
Rich Chicken and Marrow Bone Broth
This recipe creates a deeply flavorful, nutrient-dense broth using a whole chicken and roasted marrow bones. The result is a rich, gelatinous broth perfect for sipping, cooking, or using as a base for soups.
Ingredients
1 whole chicken (3-4 lbs), thawed
Frozen roasted marrow bones (as many as you have)
1-2 tablespoons apple cider vinegar or lemon juice
1 large onion, quartered (no need to peel)
2-3 carrots, roughly chopped
2-3 celery stalks, roughly chopped
4-6 garlic cloves, smashed
2 bay leaves
1 tablespoon whole peppercorns
Fresh herbs (parsley, thyme, rosemary - optional)
Cold water to cover
Salt (add at the end)
Instructions
Thaw the Chicken
Thaw your frozen chicken safely in the refrigerator for 24 hours, or use the cold water method (submerge in cold water, changing every 30 minutes for 2-3 hours).
Start the Broth
Place the whole raw chicken and frozen roasted marrow bones in a large stockpot (at least 8 quarts).
Add the vinegar or lemon juice - this helps extract minerals from the bones.
Cover everything with cold water, leaving about 2 inches of space at the top of the pot.
Add onion, carrots, celery, garlic, bay leaves, and peppercorns.
Initial Simmer
Bring to a boil over medium-high heat, then immediately reduce to a gentle simmer (small bubbles, not a rolling boil).
Skim off any foam or scum that rises to the surface in the first 15-20 minutes.
Simmer uncovered or with the lid slightly ajar for 45-60 minutes.
Remove the Chicken Meat
After 45-60 minutes, the chicken will be fully cooked. Carefully remove the whole chicken from the pot using tongs or a large slotted spoon.
Let it cool slightly on a cutting board, then pull off all the meat for other uses.
Return the carcass (bones, skin, cartilage) to the pot and continue simmering.
Continue Simmering
Simmer the chicken carcass and marrow bones together for another 1-2 hours (2-3 hours total for chicken bones).
Remove and discard the chicken bones - they've given all they can.
Continue simmering with just the marrow bones for another 2-4 hours (4-6+ hours total for marrow bones).
Add fresh herbs in the last 30 minutes if desired.
Strain and Season
Strain the broth through a fine-mesh strainer or cheesecloth into a large bowl or container.
Discard the solids.
Season with salt to taste.
Let cool, then refrigerate. A layer of fat will solidify on top - you can remove it or stir it back in.
Storage
Refrigerator: 5-7 days
Freezer: 3-6 months (freeze in portions for easy use)
Notes
The broth should gel when cold - this means you've extracted plenty of collagen and gelatin.
For even richer broth, simmer the marrow bones for up to 12-24 hours.
Don't add salt until the end - you want to taste the finished broth before seasoning.
The cooked chicken meat can be used for soups, salads, sandwiches, or any recipe calling for cooked chicken.
Yield
Approximately 3-4 quarts of rich, flavorful broth
