    Is this the same Jacques Anquetil that died of stomach cancer at the ripe old age of 53? Coincidently the average life expectancy of a traditional Inuit…

    I seem to remember that one of the reasons why humans developed bigger brains is because we started eating more meat.

    There are many suggestions and no proofs
    However many many animals eat meant and many of them eat more than us but none are any brighter. I conclude eating meat is unlikely to be a sole causal factor in intelligence. Did it contribute possibly?

    One study, published last month in the journal Proceedings of the National Academy of Sciences, examined the brain sizes of several primates. For the most part, larger bodies have larger brains across species. Yet human have exceptionally large, neuron-rich brains for our body size, while gorillas — three times more massive than humans — have smaller brains and three times fewer neurons. Why?

    The answer, it seems, is the gorillas’ raw, vegan diet (devoid of animal protein), which requires hours upon hours of eating only plants to provide enough calories to support their mass.

    Researchers from Brazil, led by Suzana Herculano-Houzel, a neuroscientist at the Federal University of Rio de Janeiro in Brazil, calculated that adding neurons to the primate brain comes at a fixed cost of approximately six calories per billion neurons.

    For gorillas to evolve a humanlike brain, they would need an additional 733 calories a day, which would require another two hours of feeding, the authors wrote. A gorilla already spends as much as 80 percent of the tropic’s 12 hours of daylight eating.

    Similarly, early humans eating only raw vegetation would have needed to munch for more than nine hours a day to consume enough calories, the researchers calculated. Thus, a raw, vegan diet would have been unlikely given the danger and other difficulties of gathering so much food.

    Cooking makes more foods edible year-round and releases more nutrients and calories from both vegetables and meat, Herculano-Houzel said.

    “The bottom line is, it is certainly possible to survive on an exclusively raw diet in our modern day, but it was most likely impossible to survive on an exclusively raw diet when our species appeared,” Herculano-Houzel told LiveScience.

    Tanzania reveal that the child had porotic hyperostosis, a type of spongy bone growth associated with low levels of dietary iron and vitamins B9 and B12, the result of diet lacking animal products in a species that requires them.

    Ohohoh so much for chemicals ruining our ability to produce B12.

    So plant eating gorillas are not as intelligent as us because they spend too much time eating ?

    That will explain why my two meat eating cats that spend most of their lives sleeping and only waking up to stretch, eat, and shit, are far more intelligent than gorillas. Or even humans for that matter.

    Whooosh.

    Did the article/journals make any claims to answer that? No.

    Well, the cats have managed to get you to run around doing everything for them whilst they just chill out all day so yeah, I could probably name one human they are more intelligent than.

    Study into death by malnutrition discovers vitamin deficiency shocker. This example was a breastfeeding child so the difficiency was the mothers. Its not possible to know why she was deficient…

    But…

    http://en.m.wikipedia.org/wiki/Porotic_hyperostosis

    “low level of iron in the blood is also a defense against pathogens, so a high incidence of the disease in a population could also indicate an attempt to fight off an infectious disease.[4] From this perspective, porotic hyperostosis could be viewed as a biological attempt to adapt to the environment, rather than an indicator of malnutrition”

    Fwiw I only said its possible for b12 synthesis. Its an embryonic area of research.

    Gorillas are vegan = falsehood. Gorillas are biological frugivores who can and do eat other animals… uncooked.

    The reasons human brains grew is complex and largely unknown, but current theory suggests likely due to cooking than anything else because it allowed rapid consumption and absorbtion of nutruents… 2, 000cal/hour easily.. Human brains have lost the volume of a tennis ball in the last 30k years. How does that reconcile with increased meat consumption in that period?

    Btw im not a no meat advocate. See previos posted food pyramid, thats my view.

    The encephalization quotient is the same as it always has been. Thus your last sentence bores me to no end. There are of course other factors that contribute to brain development but at the end of the day, you have to fuel that brain. Your willingness to jump to conclusion and use rather specious unrelated arguments in at attempt to discredit the links I posted is irritating at the very least and intellectually bankrupt at the very worst.

    Link please? Current theory seems to suggest it was a combination of eating meat and cooking – without either then brain growth could not have been supported.

    Gorrilla eat very very little meat, to the point that the original articles argument is still valid.

    If you are bored stop reading. You’re edging into the lowest form of argument.

    The traditional explanation is that human ancestors scavenged carcasses for high-quality food that preceded the evolutionary shift to smaller guts and larger brains

    Ohohohoh

    But…

    The point being, that you clearly missed, is that humans…without all those nasty nasty pescticides that have stopped countless millions from starving, still could not produce enough B12.

    This example was a breastfeeding child so the difficiency was the mothers. Its not possible to know why she was deficient…

    I’m assuming pesticides weren’t the cause.

    Ohohohoh

    Which means?

    Read the link. Could be cause by pathogens, not just diet. Those tanzanians could have been eating loads of animal protien, but an environmental pathogen caused anemia in the population.

    One fact thats absolutely certain is that a vegan diet would be good for the more follically challenged amongst us. Its what Junkyard credits his continued modelling success too. And he’s just finished his latest campaign for L’oreal. I’m sure that we can all agree that with the moobs his vegan diet has endowed him with, he’s most definitely worth eet! 😀

    Really ? You couldn’t work out what allmountainventure’s point was ? It was written in straightforward plain English.

    Eating only meat and nothing else is very bad for you. But eating only produce derived from plants/trees and nothing else isn’t so bad for you. HTH

    Well that’s such a glaringly obvious and useless thing to say I’d assumed there was another point I was missing. Did you also know the sky is blue?

    Come on, you’re making this too easy!!

    Making what too easy? You’re trying to tell us that we don’t need to eat meat? We all know this already.

    Are you saying that meat is actually bad for us? I don’t believe this and you’ll have to do a lot better to convince me.

    Are you saying that humans havne’t evolved to eat meat? This is just wrong.

    Incidentally, I have heard a theory that says that suggests early humans lived on the shoreline, where they could eat lots of seafood rich in omega whatever and their brains could grow big.

    So plant eating gorillas are not as intelligent as us because they spend too much time eating ?

    Not sure some of you really understand natural selection. Species don’t develop things randomly, they need external pressures. So Gorillas who are happy munching plants and succeeding as a species don’t have any imperative to develop a bigger brain – why goto the trouble? It causes humans enough problems.

    At some point in history early hominids were in a situation where superior intelligence gave them an advantage and helped them survive – and they had the diet to support the larger brain mutation. If gorillas had that situation tomorrow, they would start looking for new food sources – and probably eating more meat.

    Not sure some of you really understand natural selection.

    And I’m not sure some people really understand pisstaking.

    This might come as a terrible shock to you but I don’t actually think that cats are far more intelligent than humans because they have a lot of spare time after eating their meaty meals. I thought that was obvious but maybe not 🙂

    Well that wasn’t aimed at you.. but others seem to think that big brains developed simply because diet changed, which isn’t really the case.

    Fair enough. I had assumed because you had quoted me that it was aimed at me.

    Making what too easy?

    It was a joke really. Someone names a steak eating athlete as an alternative to the fruitarian athlete The steak eater sadly died age only 53 of stomach cancer. Rather ironic example I thought.

    Well that’s such a glaringly obvious and useless thing to say I’d assumed there was another point I was missing.

    There was actually. I was using that as an illustration of my statement that humans frugivore roots and the common misconception that humans are biological omnivores. We are not designed to eat animal protien but have adapted to it… not that well actually.

    Im not a no meat advocate, unless we are talking modern farmed animals or red meat which should be avoided at all costs. Even if you are getting wild animals, more than once a week is too much imo.

    Do sausage rolls count as wild animals if you buy them at the Gregg’s in Salford precinct though?

    Yes. But must be eaten raw to benifit from the fatist acid.

    I don’t think it illustrates that particularly well.

    We are not designed to eat animal protien

    I really don’t think we’re DESIGNED to do anything. Everything we can do is an adaptation, and we adapted to eat meat a really really really really long time ago. Way before we were hominids, even.

    Some knowledgeable answers here.

    I really don’t think we’re DESIGNED to do anything.

    [Assuming no facetiousness in your question]

    A mixture of mechanical ingenuity and physiological adaptation.
