A new study has produced strong evidence that red meat consumption is a trigger for inflammatory bowel disease (IBD), demonstrating how it alters gut bacteria and immune activity in ways that worsen inflammation. It furthers scientific knowledge of the many pathways involved in inflammation, taking…
What do you think happens when a mouse finds a large carcass in the wild? They just take a few nibbles and then go “that’s enough, time for some greens now. Gotta keep my diet balanced”. No, they gorge themselves on the opportunistic meal and will return each night until it’s gone or inedibly rotten.
The study is fine. The conclusions, interesting. The sudden ‘mouse diet & gut-study experts’ disagreeing because they don’t like it, reminds me of Facebook tbh.
Humans historically, also didn’t eat much meat up until very recently. More recent research suggests our ancient human ancestors were eating far more plants than meat
EDIT: For example:
Here we present the isotopic evidence of pronounced plant reliance among Late Stone Age hunter-gatherers from North Africa (15,000–13,000 cal BP), predating the advent of agriculture by several millennia
Isotopic testing shows that early humans primarily subsisted on herbivores and small game, including fish. Please refer to this study for Europe.
Early modern humans also appear to have regularly hunted large herbivores (55–57), but there is also evidence for the use of small game, including fish at some of these sites (15, 16).
based on stable isotopes, the mammoth seems to contribute the major part of the dietary protein of humans in a time range between 50,000 and 30,000 years ago and across wide areas spanning from SW France11 to the Crimean Peninsula53 (Fig. 6, Supplementary Fig. 5–8).
It is inaccurate to state that humans did not eat much meat prior to modern times.
This is just not true in the bigger picture of human evolution. That paper focuses on humans in North Africa 15,000–13,000 years ago which is a very tiny snapshot in time and geography.
Humans and human ancestors have also been consuming large quantities of plants for far earlier than that. Here’s another paper looking 780,000 years ago finding a wide amount of plants consumed
we demonstrate that a wide variety of plants were processed by Middle Pleistocene hominins at the site of Gesher Benot Ya’aqov in Israel (33° 00’ 30” N, 35° 37’ 30” E), at least 780,000 y ago. These results further indicate the advanced cognitive abilities of our early ancestors, including their ability to collect plants from varying distances and from a wide range of habitats and to mechanically process them using percussive tools.
I am not saying that hunting didn’t happen (it definitely did). I am just saying that more recent research is painting a very different picture of the level of consumption of it
If a species is straight up annihilating multiple species merely through predation, it’s not statistically possible for it to be a small amount of meat. A wide variety of plants eaten, as pointed out in that paper, doesn’t mean it was mostly a plant diet - if anything, that means it’s likely humans primarily only ate plants while traveling during a hunt.
yes, of course we ate lots of plants as well, that was never disputed. We were hunters and gatherers. The point is meat has absolutely been a significant part of our diets for millions of years (the exact ratio depending on the environment humans found themselves in). it is well documented by many direct lines of evidence as i laid out above.
I am not saying that hunting didn’t happen (it definitely did).
My point is that it was way more rare than what people’s diets look like today. Not zero but not dominant. Wide reliance on plants is even true before modern agriculture. For example:

I myself am a victim of the modern diet, and lack of exercise. I almost died of high cholesterol and other related factors, before I started to eat better and be physically active.
I’m a firm believer in a varied diet, and that most people should have a less meaty intake.
Just, we are designed to be hunters and eat red meat
My parents fed me red meat for almost every dinner I can recall growing up. I’m early 30s and my cholesterol is very high. I was able to drop my cholesterol significantly in one month by changing my diet to mostly vegan with chicken and fish once or twice a week. Switched my morning eggs out to egg whites. Cooked in avocado oil instead of butter.
Steppe populations from modern Ukraine easy through to the Urals lived mainly on meat and dairy 5000 years ago (even if they didn’t yet have the lactose tolerance adaptation).
In the animal study, mice were fed three types of red meat – pork, beef and mutton – every day for two weeks. Then, the researchers triggered colitis (a model for IBD) using a chemical called dextran sulfate sodium (DSS).
They definitely aren’t evolved to eat dextran sulfate sodium.
Was the first thing I thought of. “Standard diets,” vs non-standard pretty quickly calls into question how much we need to account for the divergence from typical. If I go to India (I’m from the USA), there will be meals that aren’t standard for me that might cause distress that are nonetheless fine for the local population.
We haven’t been eating like this for a few million years, humans mostly subsisted off of whatever they could get. Eating red meat every day, or even every week, is very modern.
Homo primates (archaic humans like Homo Erectus) have been hunting prolifically for about 2 million years. That’s part of what makes us Homo; the large calorie surplus from big game hunting allowed our brains to grow larger.
afaik it’s inconclusive, and just as likely that big game was rare and supplemented by many other forms of hunting and gathering. It’s a lot easier to spear a fish or steal some eggs than to spend a whole day tracking down an elk until it collapsed from exhaustion.
More modern research does not suggest this made up most of the consumption for humans even before agriculture. For instance,
Our results unequivocally demonstrate a substantial plant-based component in the diets of these hunter-gatherers. This distinct dietary pattern challenges the prevailing notion of high reliance on animal proteins among pre-agricultural human groups
I assume most mice don’t regularly eat large livestock.
Are mice evolved to eat red meat? The article doesn’t really say.
Yes, mice eat red meat.
Mice are omnivores and are opportunistic eaters. They’ll eat whatever they can find.
Mice do not eat that much meat of other mammals.
Giving an over abundance of it, for a long time, will shock the mouse.
What do you think happens when a mouse finds a large carcass in the wild? They just take a few nibbles and then go “that’s enough, time for some greens now. Gotta keep my diet balanced”. No, they gorge themselves on the opportunistic meal and will return each night until it’s gone or inedibly rotten.

The study is fine as you say, the problem is the news cycle throwing around a very contrived mouse study as anti-meat news for humans.

Or this study, also from Nature, again studying the first modern humans and late Neandertals in Europe:

Eating meat is a major part of what separated archaic humans from other primates; it is theorized that the calories from meat is part of what helped us grow our larger brains. Homo Habilis was eating meat 2.6 million years ago, well before Homo Sapiens even existed. Homo Erectus hunted to the point of wiping out many large herbivores over a 1.5 million year time period. They are meat regularly enough for tapeworms to speciate specifically for us as hosts.
Humans and human ancestors have also been consuming large quantities of plants for far earlier than that. Here’s another paper looking 780,000 years ago finding a wide amount of plants consumed

Or when meat was scarce!

it didn’t just “happen” like once in a while. we are/were probably the best hunters ever seen on planet earth. we basically wiped out global megafauna over the last 1.5 million years.
what exactly do you mean by “very different picture”? that’s an extremely vague statement that could mean almost anything.
Primates in general are designed to eat red meat. Chimps, our closest cousin, go on regular hunts against other primates, and eat them
My point is that it was way more rare than what people’s diets look like today. Not zero but not dominant. Wide reliance on plants is even true before modern agriculture. For example:

That’s very impressive. Dietary factors generally account for a very small proportion of blood LDL. Your diet must have been very poor and you likely have some known genetic mutations which greatly exacerbate the issue.
I tend to eat very little red meat now, maybe once a month. I used to eat it every day
It depends on the populations.
Steppe populations from modern Ukraine easy through to the Urals lived mainly on meat and dairy 5000 years ago (even if they didn’t yet have the lactose tolerance adaptation).

They haven’t. So haven’t we. 😄
Humans been eating big game ever since we figured how to hunt it.
You still go hunting or are you buying factory meat?
Did you build your own house or did you buy it?
In fact Homo Erectus beat us to it by a couple million years.
You mean a few million years of evolution couldn’t completely redesign our digestive system? Weak bruh.
Too bad humans are only like 200,000 years old.
Science < Wacky claims that confirm indoctrinated myths.
We haven’t been eating like this for a few million years, humans mostly subsisted off of whatever they could get. Eating red meat every day, or even every week, is very modern.
Fair, but our guts have already evolved to not being able to eat rotten meat. They’re apples and oranges, but still a relevant point.
Dietary evolution happens really fast, comparatively speaking.
Cool story.
Wierdo.
