CARTA: The Evolution of Human Nutrition

Tracing the evolution of the human diet from our earliest ancestors can lead to a better understanding of human adaptation in the past. It may also offer clues to the origin of many health problems we currently face, such as obesity and chronic disease. This fascinating series of talks focuses on the changing diets of our ancestors and what role these dietary transitions played in the evolution of humans. Leslie C. Aiello (Wenner-Gren Foundation) begins with An Overview of Diet and Evolution, followed by Richard Wrangham (Harvard Univ) on Fire, Starch, Meat, and Honey Steven Leigh (Univ of Illinois at Urbana-Champaign) on Diets and Microbes in Primates.

You know what I love about this talk? There is no bias towards one diet or another. Thank you and thank God

[@asecretturning]

Wtf

[@veganevolution]

It's absolutely bias to indicate that meat eating was necessary for growth of the modern human! But it's so ingrained so hard to tell... The truth is that animal sources simply provided calories when the climate became dry in southern Africa, and some of us fled north. These meat products did nothing to enhance our species, but only sustained our species throughout period of drought, and then in the winter up north. After that hunting simply became habit

Did humans adapt to the food available to them and over time their bodies "learned" to process these foods nutritionally? For instance, lets say a "tribe" of humans in 4600 B.C. has to leave an area for whatever reason into an area with a totally different diet. Their bodies are not used to these foods and may not agree with them as they have been eating other foods for centuries. Does the first generation to the new area struggle nutritionally from the new diet and over time the following generations adapt via a nutritional evolution of sorts?

Seems impossible to nail down the perfect nutritional foods when we all evolved from ancestors from so many different geological locations. The diets in these areas are wide and varied. The Inuits of North America subsisted on nearly all meat. The Japanese ate a LOT of fish. I suppose if your DNA says you are mostly from one area of the globe, this approach may have some validity. If your DNA is from all over the place, your diet will have to be assessed by more trial and error.

If they were eating animals or seeds (nuts) they didn't have a fat free diet. I've been studying the San Bushmen, whose DNA is the oldest known. They traditionally foraged, hunted, and were occasionally successful, but relied on the nuts, roots, and fruits they gathered. There was a bone study that determined the probable ratio of their various foods was in the 70-80% range for plant-based foods.

[@MS45636]

@@GeckoHiker nice info Sandra thanks!

[@ulus2109]

fruits like avacados contain alot of good fats, olives too, and nuts too

[@GeckoHiker]

Poor research, or just poor conclusions--it's hard to tell. Nuts and seeds would have had ample fat that all humans need in their diet. The occasional "successful hunt" would have provided even more. Carbs are the luxury foods that make humans obese.

[@davfar459]

Lmao civilizations before modernization relied heavily on carbs from grains, fruit, and vegetables, even our primate relatives consume carbs from fruit and other sources, if anything it's the hyper availability of meat and dairy products that's the luxury that also makes people obese.

[@GeckoHiker]

@@davfar459 Farm-based "civilizations" are less than 10,000 years old. Even as recently as a 120 years ago, the output of farming communities was used mainly for alcohol and bread production (and trade), not to supply vegetables. And once humans begain living that way, overall health declined even as lifespans marginally improved. Our digestive evolution occurred half a million years before the first inkling of farming for carbs or herding animals for dairy and meat. Gatherer-hunter tribes that are still living that lifestyle today have been carefully studied and it was determined that 70-80% of their calories comes in the form of fats from nuts and seeds. Particularly the mongongo nut in Africa. Gathering is their tried and true method of getting calories. Hunts are nice to have, but not guaranteed to be successful. The lesson some of us have learned is that civilization can give us longer lifespans because we are sheltered and don't have to work as hard to survive, while a gather-hunter diet gives optimal nutrition and better overall health, without dairy or grains. Any carbs should come with lots of fiber. Personally, I follow the coastal gatherer-fisher lifestyle. Greens, nuts, some seeds, vegetables, a few high-fiber tubers, eggs, insects, mollusks, fish, berries, and very, very occasionally, fruit or honey. (in order of how easy these are to find when foraging). Our innate primate digestive system is optimized for this type of diet.

[@davfar459]

@@GeckoHiker Actually the consumption of many grains and vegetables, especially fruit and nuts, and legumes goes back millions of years ago, we also lost our ability to self produce vitamin c because within our earlier stages we consumed it from fruit in very high amounts and the length of our intestines and the structure of our teeth supports the fact that we're designed to consume plants also more evidence that humans are healthier when consuming more carbs than fat goes too when comparing two examples of the intuit tribes and the Japanese Okinawans, the inuit tribal mummies who consumed mainly protein and fat were observed to frequently suffer from athlerscrlosis and parasites and they never found an inuit mummy to have been older than around 35 years old so it's clear they tended to have very short lifespans but as the Okinawans who were observed to have the longest life expectancy out of every other tribes and group of people on the world consumed mainly sweet potatoes, vegetables, and legumes. I think where your getting the idea that living tribes today consume "70-80%" of their calories of fat comes from the book known as the enthographic atlas where 80% of the tribes observed far northern inuit tribes where their environment had very little vegetation so it's obvious that those people consumed more meat but as you go down south to the equator the living tribes there consume far more fruits, grains, and vegetables. Your also forgetting the the herding of animals and dairy consumed is also a very recent practice that recently became available to people worldwide.

[@GeckoHiker]

@@davfar459 No, the consumption of legumes, grains and vegetables does not go back millions of years. Chemical analysis shows that the primates we evolved from subsisted on green vegetation, nuts, birds, eggs, amphibians, berries, and occasionally, fruit. Vegetables as we have come to know them didn't exist back then. Grains and legumes need careful handling to be edible today, if their precursors existed that far back in time. Most all the grains, seeds, and legumes we eat today were developed by humans in the past 6000-8000 years, through selective breeding. You keep coming back to modern foods but our dietary system did not develop on modern foods.

[@davfar459]

@@GeckoHiker Yes legumes, grains and vegetables as they did exist back then were consumed by the populations that lived near them, even though they were altered through selective breeding since then they nevertheless existed and were consumed and our own saliva even contains enzymes to digest starch, the farm animals were selectively breeded as well, other birds in the wild rarely lay unfertilized eggs and cows were also breeded to produce far more milk than they used to.

[@Dan0rioN]

Seems there has been no conclusion drawn from this as to what the optimal diet is for modern man. With much conflicting information including the observation of our closest current relatives and the evolution of our past ancestors, Ive taken to science and concluded that a pescetarian diet is optimal. Raw fruits, nuts, cooked veggies and fish. Everything else in moderation. This is a science based nutrient dense diet opposed to a theory based fad diet that often disclude entire food groups and leave people feeling dissatisfied. Any insights are appreciated.

Brains were built on high glucose loads, not from muscle tissue.

[@Jefferdaughter]

Rabbits are typically too lean to help fuel the brain. Fish and shellfish could be useful foods, or course. Hunting was originally done by everyone in the group, including women, children, and babes in arms, all making noise and driving herds over cliffs. Paleologists have long known of this, from the piles of bones found, with only some showing butchering marks. Later stone corrals or natural box canyons were used, with spears and the like used to dispatch the animals. Snares, nets, bolas... Humans did get good enough at hunting to hunt many species to extinction. This was also seen on islands. Even though our brains have reduced in average size about 10% since we began relying on plant agriculture, it seems that there were some things we humans just didn't 'get', even when our brains were bigger.

Animal foods are the most difficult to digest and they putrefy in our long intestines, so her theory is thin. Also, chimps are known to use tools and eat meat, but we are studying them, not the other way around. What is it about humans that make us so unique considering we share 98% of our DNA with apes? We use fire to cook, and utilize the starchy storage organs of plants! Our characteristic reduced facial features would be the result of no longer needing to process such intense levels of tough plant fibers which allowed our jaw, lips and teeth to reduce, as well as our reduced guts and also explain our extra copies of amylase, the enzyme that breaks down starches. I think the newer theory about our discovery of plant storage organs in combination with utilizing fire to cook and make nutrients more available makes a whole lot more sense as to why our brains grew, and also explains the reduction of the physical changes in the other areas too. Just because we don't have concrete proof of the history of fire usage does not mean it didn't happen long before what we can show so far. Cooked bones fossilize, but how could we quantify cooked plant matter that would not? If meat was such a big player in developing big brains, why aren't the other apes just as big brained, and why aren't the true carnivores smartest of all? Also, nature always supplies it's creations with all the inherent attributes necessary to feed themselves and their young efficiently. I challenge anyone to go out into the wild sans tools and weapons and try to catch even a chipmunk with your native physiology! And IF you somehow manage, you just bite off big chunks of it raw and gulp it down, still warm and bloody with no seasoning... and only then call yourself a carnivore or even an omnivore! We are both inept at hunting, and disgusted at even the thought, let alone the act of eating it like a true meat eater does, but my kitty cat would be very efficient and ecstatic, because he is evolved for the task. Humans do have the anatomical apparatus to gather really well however... plants, tubers, fruits, nuts, seeds, insects, grubs, mollusks, even shellfish or other easy to harvest water based animals...and the ability to run...AWAY from predators initially, not in pursuit of them. I wonder if maybe our increasingly poor health, stress levels, and mental illnesses are so rampant because we are no longer interacting with our natural surroundings as we have evolved to do, and are living in an industrial, chemicalized, artificial world with artificial diets?

[@youwhatmadeidk]

How well or efficient we digest certain foods has no correlation with health. Many fibrous foods take time to digest, with most of it simply passing through the intestines (which is beneficial to feed bacteria). Modern grain based food like bread digests very quickly yet is bad for you. Eggs don't fit the the stereotype of animal foods being harder to digest also, they digest fast and efficient - in fact, eggs are one of the most easily digestible foods. That doesn't fit your straw man narrative at all.

[@mattp4735]

Our stomach PH is 1.5 which dissolves meat and animal food into a slurry in a couple hours, which Is readily absorbed by the first part of the small intestines. Just because putrefying type bacteria exist in the colon to polish off the last bits doesn't mean meat is "putrefying" or rotting in our gut as you are implying. It's a vegetarian myth, like the myth that meat eating tribes in the arctic prized the undigested contents of the Ruminant's stomach. Simply not true.

[@Jefferdaughter]

So true, Matt. The people who lived entirely or almost entirely by consuming animals in recorded history (including Masai, some American Indians, Mongols, other herding peoples) prized fat above all. After that, the organs, including the creamy, custard like brain. And much of that was eaten raw, or nearly so. Have you seen the presentations on the use of stable isotopes to determine what early humans ate? It shows that we were 'super carnivores', eating herbivores and other carnivores. This was the energy boost that allowed humans to develop huge brains, relative to overall body mass. After plant crop agriculture was widely adopted (likely because most of the large animals once preferred for food were hunted to extinction), not only did the average height, bone density, and dental health decline - human brains also became smaller, by an average of 10%. Interesting, eh? The ancient Greeks spoke of being devolved from the people who came before them. Maybe they knew more than we thought they did.

Ancient beers were about 1% alcohol and consumed for supplemental nutrition & calories as we'd not yet developed modern distillation methods which hyper-concentrate (i.e. "refine") the alcohol content.

Lesson for us today: eat real food. No processed food heavy in sugar useless starches and fake fats. No Mountain Dew and M&Ms. No frozen lasagna. If you become a fat burner like our ancestors you dont need to eat 6 times a day. You dont even need to eat every day.
