So how do hunter-gatherers get energy when theres no meat? It turns out that man the hunter is backed up by woman the forager, who, with some help from children, provides more calories during difficult times. When meat, fruit, or honey is scarce, foragers depend on fallback foods, says Brooks. The hadza get almost 70 percent of their calories from plants. The kung traditionally rely on tubers and mongongo nuts, the aka and baka pygmies of the congo river Basin on yams, the Tsimane and Yanomami Indians of the Amazon on plantains and manioc, the australian Aboriginals on nut grass and water chestnuts. Theres been a consistent story about hunting defining us and that meat made us human, says Amanda henry, a paleobiologist at the max Planck Institute for evolutionary Anthropology in leipzig. Frankly, i think that misses half of the story.

Today markets offer more variety, but a taste for meat persists. The real Paleolithic diet, though, wasnt all meat and marrow. Its true that resume hunter-gatherers around the world crave meat more than any other food and usually get around 30 percent of their annual calories from animals. But most also endure lean times when they eat less than a handful of meat each week. New studies suggest that more than a reliance on meat in ancient human diets fueled the brains expansion. Year-round observations confirm that hunter-gatherers often have dismal success as hunters. The hadza and Kung bushmen of Africa, for example, fail to get meat more than half the time when they venture forth with bows and arrows. This suggests it was even harder for our ancestors who didnt have these weapons. Everybody thinks you wander out into the savanna and there full are antelopes everywhere, just waiting for you to bonk them on the head, says paleoanthropologist Alison Brooks of george washington University, an expert on the dobe kung of Botswana. No one eats meat all that often, except in the Arctic, where Inuit and other groups traditionally got as much as 99 percent of their calories from seals, narwhals, and fish.
When biological anthropologist Clark Spencer Larsen of Ohio state University describes the dawn of agriculture, its a grim picture. As the earliest farmers became dependent on crops, their note diets became far less nutritionally diverse than hunter-gatherers diets. Eating the same domesticated grain every day gave early farmers cavities and periodontal disease rarely found in hunter-gatherers, says Larsen. When farmers began domesticating animals, those cattle, sheep, and goats became sources of milk and meat but also of parasites and new infectious diseases. Farmers suffered from iron deficiency and developmental delays, and they shrank in stature. Despite boosting population numbers, the lifestyle and diet of farmers were clearly not as healthy as the lifestyle and diet of hunter-gatherers. That farmers produced more babies, larsen says, is simply evidence that you dont have to be disease free to have children. The Inuit of Greenland survived for generations eating almost nothing but meat in a landscape too harsh for most plants.
Erectus, the human body has depended on a diet of energy-dense food—especially meat. Fast-forward a couple of million years to when the human diet took another major turn with the invention of agriculture. The domestication of grains such as sorghum, barley, wheat, corn, and rice created a plentiful and predictable food supply, allowing farmers letter wives to bear babies in rapid succession—one every.5 years instead of one every.5 years for hunter-gatherers. A population explosion followed; before long, farmers outnumbered foragers. Over the past decade anthropologists have struggled to answer key questions about this transition. Was agriculture a clear step forward for human health? Or in leaving behind our hunter-gatherer ways to grow crops and raise livestock, did we give up a healthier diet and stronger bodies in exchange for food security?
Raymond Dart, who in 1924 discovered the first fossil of a human ancestor in Africa, popularized the image of our early ancestors hunting meat to survive on the African savanna. Writing in the 1950s, he described those humans as carnivorous creatures, that seized living quarries by violence, battered them to death slaking their ravenous thirst with the hot blood of victims and greedily devouring livid writhing flesh. Eating meat is thought by some scientists to have been crucial to the evolution of our ancestors larger brains about two million years ago. By starting to eat calorie-dense meat and marrow instead of the low-quality plant diet of apes, our direct ancestor, homo erectus, took in enough extra energy at each meal to help fuel a bigger brain. Digesting a higher quality diet and less bulky plant fiber would have allowed these humans to have much smaller guts. The energy freed up as a result of smaller guts could be used by the greedy brain, according to leslie aiello, who first proposed the idea with paleoanthropologist Peter Wheeler. The brain requires 20 percent of a humans energy when resting; by comparison, an apes brain requires only 8 percent. This means that from the time.
Healthy, eating for Children-Topic overview
The notion that were trapped in Stone Age bodies in a fast-food world is driving the current craze for Paleolithic diets. The popularity of these so-called caveman or Stone Age diets is based on the idea that modern humans evolved to eat the way hunter-gatherers did during the paleolithic—the period from about.6 million years ago to the start of the agricultural revolution—and that our genes. A stone Age diet is the one and only diet that ideally fits our genetic makeup, writes Loren Cordain, an evolutionary nutritionist at Colorado State University, in his book. The paleo diet: Lose weight and Get healthy by eating the foods you were designed to eat. After studying the diets of living hunter-gatherers and concluding that 73 percent of these societies derived more than half essays their calories from meat, cordain came up with his own Paleo prescription: Eat plenty of lean meat and fish but not dairy products, beans, or cereal.
Paleo-diet advocates like cordain say that if we stick to the foods our hunter-gatherer ancestors once ate, we can avoid the diseases of civilization, such as heart disease, high blood pressure, diabetes, cancer, even acne. But is it true that we all evolved to eat a meat-centric diet? Both paleontologists studying the fossils of our ancestors and anthropologists documenting the diets of indigenous people today say the picture is a bit more complicated. The popular embrace of a paleo diet, Ungar and others point out, is based on a stew of misconceptions. The hadza of Tanzania are the worlds last full-time hunter-gatherers. They live on what they find: game, honey, and plants, including tubers, berries, and baobab fruit. Meat has played a starring role in the evolution of the human diet.
Simply put, a diet that revolves around meat and dairy, a way of eating thats on the rise throughout the developing world, will take a greater toll on the worlds resources than one that revolves around unrefined grains, nuts, fruits, and vegetables. Until agriculture was developed around 10,000 years ago, all humans got their food by hunting, gathering, and fishing. As farming emerged, nomadic hunter-gatherers gradually were pushed off prime farmland, and eventually they became limited to the forests of the Amazon, the arid grasslands of Africa, the remote islands of southeast Asia, and the tundra of the Arctic. Today only a few scattered tribes of hunter-gatherers remain on the planet. Thats why scientists are intensifying efforts to learn what they can about an ancient diet and way of life before they disappear.
Hunter-gatherers are not living fossils, says Alyssa Crittenden, a nutritional anthropologist at the University of nevada, las Vegas, who studies the diet of Tanzanias Hadza people, some of the last true hunter-gatherers. That being said, we have a small handful of foraging populations that remain on the planet. We are running out of time. If we want to glean any information on what a nomadic, foraging lifestyle looks like, we need to capture their diet now. So far studies of foragers like the Tsimane, arctic Inuit, and Hadza have found that these peoples traditionally didnt develop high blood pressure, atherosclerosis, or cardiovascular disease. A lot of people believe there is a discordance between what we eat today and what our ancestors evolved to eat, says paleoanthropologist Peter Ungar of the University of Arkansas.

Its not enough to live on, he says. I need to hunt and fish. My body doesnt want to eat just these plants. The Tsimane of Bolivia get most of their food from the river, the forest, or fields and gardens carved out of the forest. Click here to launch gallery. As we look to 2050, when well need to feed two billion more dom people, the question of which diet is best has taken on new urgency. The foods we choose to eat in the coming decades will have dramatic ramifications for the planet.
What anthropologists are learning about the diets of indigenous julie peoples like the Tsimane could inform what the rest of us should eat. Rosinger introduces me to a villager named José mayer Cunay, 78, who, with his son Felipe mayer Lero, 39, has planted a lush garden by the river over the past 30 years. José leads us down a trail past trees laden with golden papayas and mangoes, clusters of green plantains, and orbs of grapefruit that dangle from branches like earrings. Vibrant red lobster claw heliconia flowers and wild ginger grow like weeds among stalks of corn and sugarcane. Josés family has more fruit than anyone, says Rosinger. Yet in the familys open-air shelter Felipes wife, catalina, is preparing the same bland porridge as other households. When i ask if the food in the garden can tide them over when theres little meat, felipe shakes his head.
ancient Tsimane Indian tribe. Its the rainy season, when its hardest to hunt or fish. More than 15,000 Tsimane live in about a hundred villages along two rivers in the Amazon Basin near the main market town of San Borja, 225 miles from la paz. But Anachere is a two-day trip from San Borja by motorized dugout canoe, so the Tsimane living there still get most of their food from the forest, the river, or their gardens. Im traveling with Asher Rosinger, a doctoral candidate whos part of a team, co-led by biological anthropologist William leonard of Northwestern University, studying the Tsimane to document what a rain forest diet looks like. Theyre particularly interested in how the Indians health changes as they move away from their traditional diet and active lifestyle and begin trading forest goods for sugar, salt, rice, oil, and increasingly, dried meat and canned sardines. This is not a purely academic inquiry.
The children are sad when there is no meat, maito says through an interpreter, as she swats away mosquitoes. Nate left before dawn on this day in January with his rifle and machete to get an early start on the two-hour trek to the old-growth forest. There he silently scanned the canopy for brown capuchin monkeys and raccoonlike coatis, while his dog sniffed the ground for the scent of piglike peccaries or reddish brown capybaras. If he was lucky, nate would spot one of the biggest packets of meat in the forest—tapirs, with long, prehensile snouts that rummage for buds and shoots among the damp table ferns. This evening, however, nate emerges from the forest with no meat. At 39, hes an energetic guy who doesnt seem easily defeated—when he isnt hunting or fishing or weaving palm fronds into roof panels, hes in the woods carving a new canoe from a log. But when he finally sits down to eat his porridge from a metal bowl, he complains that its hard to get enough meat for his family: two wives (not uncommon in the tribe) and 12 children.

By ann Gibbons, photographs by matthieu paley, some experts say modern humans should eat from a stone Age menu. What's on it may surprise you. Fundamental feasts For some cultures, eating off the land is—and always has been—a way of life.
