With an infant girl nursing at her breast and a seven-year-old boy tugging at her sleeve, she looks spent when she tells me that she hopes her husband, Deonicio Nate, will bring home meat tonight.
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. The story is similar for each of the families I visit in Anachere, a community of about 90 members of the ancient Tsimane Indian tribe.
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. The Tsimane of Bolivia get most of their food from the river, the forest, or fields and gardens carved out of the forest. As we look to 2050, when we’ll need to feed two billion more people, the question of which diet is best has taken on new urgency. Until agriculture was developed around 10,000 years ago, all humans got their food by hunting, gathering, and fishing.
That’s why scientists are intensifying efforts to learn what they can about an ancient diet and way of life before they disappear.
So far studies of foragers like the Tsimane, Arctic Inuit, and Hadza have found that these peoples traditionally didn’t develop high blood pressure, atherosclerosis, or cardiovascular disease. Eating meat is thought by some scientists to have been crucial to the evolution of our ancestors’ larger brains about two million years ago. Fast-forward a couple of million years to when the human diet took another major turn with the invention of agriculture. Over the past decade anthropologists have struggled to answer key questions about this transition. When biological anthropologist Clark Spencer Larsen of Ohio State University describes the dawn of agriculture, it’s a grim picture. Despite boosting population numbers, the lifestyle and diet of farmers were clearly not as healthy as the lifestyle and diet of hunter-gatherers. The Inuit of Greenland survived for generations eating almost nothing but meat in a landscape too harsh for most plants.
Year-round observations confirm that hunter-gatherers often have dismal success as hunters.
Humans also vary in their ability to extract sugars from starchy foods as they chew them, depending on how many copies of a certain gene they inherit. Studies suggest that indigenous groups get into trouble when they abandon their traditional diets and active lifestyles for Western living.
The latest clue as to why our modern diet may be making us sick comes from Harvard primatologist Richard Wrangham, who argues that the biggest revolution in the human diet came not when we started to eat meat but when we learned to cook. If Wrangham is right, cooking not only gave early humans the energy they needed to build bigger brains but also helped them get more calories from food so that they could gain weight. The Kyrgyz of the Pamir Mountains in northern Afghanistan live at a high altitude where no crops grow. Nate’s wives are cleaning two armadillos as well, preparing to cook them in a stew with shredded plantains. As family members enjoy the feast, I watch their little boy, Alfonso, who had been sick all week. The people of Crete, the largest of the Greek islands, eat a rich variety of foods drawn from their groves and farms and the sea.

What makes mine unique is the fact that I have fruit and vegetables at the bottom (right above the need for daily exercise and fluid consumption) and as half of the plate. Fruit and vegetable consumption is inversely associated with the risk of Coronary Heart Disease (Dauchet et al, J. Further, I have a separate category for leafy green vegetables additional to the foundational vegetable recommendations. I can go on and on about the beauty of greens…but there are so many other topics to delineate with respect to why I chose the food groups I did. Whole grains are the backbone of the plant-based diet as they contribute calories, fiber, protein, iron, B vitamins, trace nutrients in whole grains. At the top of my pyramid, I have listed high fat whole foods, dairy substitutes (which are great sources of fortified vitamins B12, D, and sometimes calcium), and whole food sweetened treats (which can be done by using dates, date syrup, pure maple syrup and other fruits). I also highly recommend everyone consume a vitamin B12 supplement of either 10?g daily OR 2,000?g weekly and have your serum vitamin D levels checked.

Do you have some suggestions for me I have been a vegetarian for the past 5yrs, now I am allergic to gluten and soy. I have a friend who recently gave birth, and found out her baby was allergic to soy and gluten as well.
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. 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. When I ask if the food in the garden can tide them over when there’s little meat, Felipe shakes his head.
The foods we choose to eat in the coming decades will have dramatic ramifications for the planet.
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.
They live on what they find: game, honey, and plants, including tubers, berries, and baobab fruit. 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. 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.
As the earliest farmers became dependent on crops, their diets became far less nutritionally diverse than hunter-gatherers’ diets. It’s true that hunter-gatherers around the world crave meat more than any other food and usually get around 30 percent of their annual calories from animals. 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. Our teeth, jaws, and faces have gotten smaller, and our DNA has changed since the invention of agriculture.
All humans digest mother’s milk as infants, but until cattle began being domesticated 10,000 years ago, weaned children no longer needed to digest milk. Populations that traditionally ate more starchy foods, such as the Hadza, have more copies of the gene than the Yakut meat-eaters of Siberia, and their saliva helps break down starches before the food reaches their stomachs. There is tremendous variation in what foods humans can thrive on, depending on genetic inheritance. Diabetes was virtually unknown, for instance, among the Maya of Central America until the 1950s.
Our human ancestors who began cooking sometime between 1.8 million and 400,000 years ago probably had more children who thrived, Wrangham says.
When I visited Wrangham’s lab at Harvard, his then graduate student, Rachel Carmody, opened the door of a small refrigerator to show me plastic bags filled with meat and sweet potatoes, some raw and some cooked. In the modern context the flip side of his hypothesis is that we may be victims of our own success. If most of the world ate more local fruits and vegetables, a little meat, fish, and some whole grains (as in the highly touted Mediterranean diet), and exercised an hour a day, that would be good news for our health—and for the planet. We follow her to the cooking hut and smell the animals before we see them—three raccoonlike coatis have been laid across the fire, fur and all.
They are used extensively in international cuisines and provide protein, fiber, iron, calcium, zinc, selenium. High fat whole foods refer to olives, avocado, nuts and seeds, which are important in order to consume adequate omega 3 fatty acids, monounsaturated fatty acids, fiber, protein, fat, iron, calcium, and trace minerals. All of these items should be used sparingly and less in situations where weight loss is a goal or when there has been a diagnosis of heart disease, diabetes, high cholesterol or other metabolic conditions.
You just have to focus on gluten-free grains and plenty of other legumes besides soy to fill in the gaps, and you probably need to prep food at home often. 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 ferns.
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. The notion that we’re trapped in Stone Age bodies in a fast-food world is driving the current craze for Paleolithic diets. 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.
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.
Digesting a higher quality diet and less bulky plant fiber would have allowed these humans to have much smaller guts.
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?
Eating the same domesticated grain every day gave early farmers cavities and periodontal disease rarely found in hunter-gatherers, says Larsen.
As a result, they stopped making the enzyme lactase, which breaks down the lactose into simple sugars. As they’ve switched to a Western diet high in sugars, the rate of diabetes has skyrocketed. Mice raised on cooked foods gained 15 to 40 percent more weight than mice raised only on raw food. We have gotten so good at processing foods that for the first time in human evolution, many humans are getting more calories than they burn in a day. Thus, I decided to work with my graphic designer, Sherri Nestorowich, to create a visual guide for the whole food, plant-based diet I recommend to my clients and students.
The starches are rich sources of complex carbs, fiber and include potatoes, squash, and corn. This section contains all whole fresh fruit and frozen fruit (which should be the priority and majority of fruit consumption) even though it can also include dried fruit, whole fruit juices, canned fruit (in order of health-promoting capacity).
Leafy greens are chock-full of macro- and micronutrients, including calcium, fiber, folate, vitamins C, B6, B2, E, potassium, manganese, magnesium, phytochemicals (such as lutein, beta-cryptoxanthin, zeaxanthin, beta-carotene).
Legumes include cooked & dried beans (adzuki, anasazi, black, black-eyed peas, cannellini, chickpeas, great Northern beans, kidney beans, lima beans, navy beans, pinto beans, soybeans), lentils, peas, split peas, and soy products (tempeh, tofu).
On the pyramid, the foods closer to the bottom should be a mainstay or foundation of intake and those near the top are to be used as support. 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.
What anthropologists are learning about the diets of indigenous peoples like the Tsimane could inform what the rest of us should eat. The popular embrace of a Paleo diet, Ungar and others point out, is based on a stew of misconceptions. 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.
When farmers began domesticating animals, those cattle, sheep, and goats became sources of milk and meat but also of parasites and new infectious diseases.
New studies suggest that more than a reliance on meat in ancient human diets fueled the brain’s expansion. After humans began herding cattle, it became tremendously advantageous to digest milk, and lactose tolerance evolved independently among cattle herders in Europe, the Middle East, and Africa. Siberian nomads such as the Evenk reindeer herders and the Yakut ate diets heavy in meat, yet they had almost no heart disease until after the fall of the Soviet Union, when many settled in towns and began eating market foods. Then his dog spotted a pack of coatis and chased them, killing two as the rest darted up a tree. This category of vegetables include kale, collard greens, spinach, mustard greens, beet greens, turnip greens, romaine lettuce, bok choy, Swiss chard, rainbow chard, Brussels sprouts, sea vegetables, broccoli, Napa cabbage.
Farmers suffered from iron deficiency and developmental delays, and they shrank in stature. 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. 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. Groups not dependent on cattle, such as the Chinese and Thai, the Pima Indians of the American Southwest, and the Bantu of West Africa, remain lactose intolerant. Today about half the Yakut living in villages are overweight, and almost a third have hypertension, says Leonard.

Posted in Diet, Meal PlansIt is the third full week of January, so you should have 3 meal plans under your belt by now. And Tsimane people who eat market foods are more prone to diabetes than those who still rely on hunting and gathering.
How are you doing with spending one hour every Saturday making a meal plan?viaHave you noticed that one hour of planning a week can save you about ten headaches during the week?! Everyone has barriers, but I encourage you to find something that will motivate you to get you over that barrier.
