CARTA: The Evolution of Human Nutrition
Vložit
- čas přidán 14. 08. 2024
- 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. Here Steven Leigh (Univ of Illinois at Urbana-Champaign) discusses Diets and Microbes in Primates, followed by Peter Ungar (Univ of Arkansas) on Australopith Diets, and Alison S. Brooks (George Washington Univ) and Margaret J. Schoeninger (UC San Diego) on Neanderthal Diets. [2/2013] [Show ID: 23436]

42:28 I've been a 100% carnivore for 16 months now and so far all my health problems disappeared and I gained muscle mass.
100% wow no fibre at all. Cannot think how that is good at all
@@carolined5923 Don't think, try it. Only after going carnivore I learned how having healthy bowels feels like. My poops are always solid and don't smell. Often there's no need to wipe after pooping (ghost wipes). I barely ever fart and when I do it doesn't smell. Everything works as nature intended because I eat what the last 4.5 million years of evolution designed our bodies to eat.
We're not gorillas, we barely get any nutrition from fiber at all. And anything we do get we can get from other sources. There's not need to introduce non-digestible, irritating and inflammatory fiber into our guts.
This video establishes a balanced view of the pre-historic diet of humanity. Evidence is presented that the early diet was often complex and included grains, roots, and vegetables. Detailed analysis of microbes, teeth, carbon isotopes, and dental fossils.
You forgot meat. Hence hunter-gatherer. Hunting in the name implies you kill animals for food.
Cooking withOUT pots nor clay: EASY !
1) Skulls of large animals or large hollow femur bones.
2) *more likely* 😁 simple weaving & woven baskets: where hot rocks from a fire are placed in the woven cooking basket ! 🔥 10 rocks is about a 5 to 8 minute boil. Rocks & boiling water do not damage basket.
🍲 😋
The Native Americans of the US used the stomachs of the deer that they killed and hooked it on a wooden tripod. Filled with water, hot stones were placed into it to bring the water to a boil and cook meat and vegetables into stews. The stomach would be good for several cooking and when it began to leak it was replaced and the old one was probably fed to their dogs.
So our ability to turn fibre into SCFA's has significantly reduced compared to other primates, yet it's somehow extremely important. Ketones fulfil this role in the gut themselves. Fibre is still not an essential nutrient.
Caribou weigh from 180 to 400 lbs, depending upon whether male or female. That's 80 to 180 kg, NOT 80 kg always. How does a scientist get that wrong? That's a potential error of 125%. Great new data about plant consumption.
Excuse me? Caribou?
Are you talking about the hind quarter?

1:08 *_Diets and microbes in primates_* (Steven Leigh)
She is not taking into account that their existed Mega-Fauna that do not exist anymore that they could have hunted.
Correct and when you over-hunt you then do not eat what you want but you eat what you can. Also assuming Neanderthal would have suffered from rabbit starvation, we shouldn't assume they were stupid, they did exist for a touch longer than 100 years and they knew to eat fat along with meat. 53:50, data "Bother me" , a researchers opinion has zero value and zero relevance. The assumption that you needed to eat every day is an assumption and most likely very incorrect.
Easily get those calories , 10's of thousands of calories from foraging and grains? Are you serious? Try it. Go out and try without modern tech to acquire that many calories from those food sources, in all seasons.
That picture at the start with the dude holding fast food is amazing
Early humans survived a lot of things, but they would not have survived that. lol
I'll save you an hour as I was starting to fade, and wondered if he'd get to the point.
15:50 Human biomes are distinct from non-human primate microbiomes. He spent much of the first fifteen minutes to come to this conclusion. So there won't be a new probiotic.
He was really mundane.
Seaweeds! Shellfish... maybe fermentation as well?
Based on nitrogen 14 and 15 data kindly explain where you come up with the idea that we ate large quantities of fiber.
Can we all remember that this account is not a commercial for you people?
This channel would be a great podcast
Humans are capable of surviving on meat alone and perfectly well adapted to a carnivore diet, especially so when there was plenty of fatty mega fauna around.
I’ve no doubt they ate fruits and vegetables as well but that seems an unreliable and inadequate source of nutrition before the advent of agriculture, especially for a highly physical lifestyle and likely made up less than %10 of total diet in my estimation.
Any that were relying heavily on vegetation as a food were most likely in a dire situation.
But the point was made that fatty fauna were not available for much of the year. A diet exclusively of lean meats would have been a recipe for starvation. I personally prefer a paleo diet, which for me includes plenty of fruit and vegetables for carbohydrate and fiber. But I'm also starting to experiment with some legumes and even grains, it's becoming clear that these were on the original paleo diet.

Animals have enough fat year round. Inuits survived with it without any plants.
I love idiot vegans yes and they have genetic traits that help them with their diet. An average westerner would not survive. Just like the Sherpa can withstand low oxygen levels at high altitudes.
@@aquamarine99911 clear, it is becoming clear to you
Depends on the nutrients you are receiving from the meat.
edit: Depending on how WELL you will survive, that is, because hell... humans can SURVIVE on almost anything - but the idea of having a nutritious diet isn't the benefit of merely surviving, it's about the quality of life you have while you're "surviving." Most humans lived in scarcity during at least some months out of the year up until the year 1980. That's right, 1980! and that's right.. MOST! The "green revolution" achieved through the cross breeding of a disease resistant, high yield version of wheat is responsible for lifting billions out of food scarcity. So don't just sit here and pretend that our ancestors weren't routinely suffering through food shortages - because they most certainly were, 99.999% of them!
Partly. Neanderthals and humans have interbred, and the DNA is still in most areas of the world (outside of Africa).
8 years ago, it's funny how that was a cutting edge discovery (although the parenthesis statement was found to be incorrect, (0.5-1% usually).)
Wonder what has developed since this video was made
We eat grasshoppers all day til we find bones then smash them against each other or find a rock near. Watch you don't step on a snake. Lets go.
most mammals are very tasty if prepared well..
18th minute Ryan Gosling's dad took the stage , baha!
You make a fabulous point. I'm with you.
Why didnt they just get coconuts of the trees
In Bradford England 🇬🇧??
Interesting that he is assuming the vegetation eaten was low quality. When a lot of greens are super vitamin dense.
But protein and fat poor. You'll starve to death on a diet of vitamins alone.
Vegetables are commonly not very bio-available. The nutrition on paper is deceiving.
Greens have protein but not enough calories for people who do not eat greens the whole day like a cow. Before grains and tubers and animal fat, our ape ancestors got enough calories from fruits.
Cooking made carbs, fat and protein more absorbable from foods.
Much of our modern vegetables and fruits have been bred over time to be higher yielding. Naturally they are poor sources of food, let alone not being very bio available.
I love Dr Atkins.Women like to hunt but made to stay home by Mr Neander.
Proteins and fats are dealt with in the human small intestine so of course those microbes wouldn't be needed in the large intestine. Every species has its 'niche', and we are essentially carnivores.
Me trying to read the comment like: 👁👄👁
mui interesate creo q comer en exeso es malo
N
.
The barley could have been cooked in a rock with a hollow area that was in the direct hot summer sun instead of a pot.
Alcohol has also been pivotal in human evolution.
thar is no connection between the neandertal and the modern human too different brenches in evolution - am i rong?
100% wrong
Definitely. There is clear evidence of Neanderthal DNA in modern humans.
You couldn't be more ronger.
You are indeed rong.
First five minutes made me wanna go poop.
Study Nut...of Ancient Kemet.
It's all in our Ancient Pre-history, or Black lore.
BLACK HISTORY...It's GONNA TAKE MORE THAN A MONTH: Before there was History, there was BLACK history!

HAVE A GREAT DAY!
Get off your fuckin high horse
what is she saing?!
