indeed.
I was asked for the recipe of my main dish by the veggie we accommodated and two of the carnivores that night.

The biota that makes B12 live in the colon. It's a water soluble vitamin. The colon absorbs water. Veggers eat a lot of fiber to feed that biota. And YES, colons do adsorb stuff, like coffee enemas (Steve McQueen) or migraine medications, and there are other medications delivered by suppository. So I wouldn't believe that colonic B12 is not the source without modern and specific study.

Unless copraphagy is another of your idiosyncrasys ?

It's not completely pseudoscience. If I found an animal that I'd never seen before and wanted to raise it, I might take a look at what other members of it's species are eating in the wild in order to find what a healthy diet to feed it would be. Seems like a good starting point.

The pseudoscience is the idea that we should just stop there, as though we haven't done any more science with respect to human diet and nutrition.

Interesting. How much animal product consumed, as a pct of total daily calories, do you think is required to achieve nutritional "balance"?

Which animal?

Fish, poultry, red meat?

And how is a balanced diet based on calories

Any animals. The implication is that for a diet to be "balanced" it requires animal products. I'd like to know how much satisfies that requirement.

How is it not?
Calories mean jack to a balanced diet.

Red meat like beef is good as it contains iron, fish omega 3, poultry (putting eggs aside as it is obvious) carbs.

And that is just the obvious ones

Then you have vitamins from things like fruit, the thingys in grains I can't remember that make you poo proper.

How much red meat needs to be added to a Vegan diet to make it "balanced"?

I meant not everything is based on calories for a balanced diet

E.g Google scurvy


Presumably a shed load of supplements

As a backward aside.

Personally had a blood test a while ago as I was feeling knackered all the time and they found I was low folic acid.

Had more veggies and supplements for a month, all normal.

A balanced diet is a broad brush.

Carbs in chicken meat?

Fair call

Made a hash of that one

Got my nutrients mixed.

It has whatever the thing is that makes athletes eat loads of it.

Related web page https://www.lifeextension.com/magazine/2006/1/awsi/Page "Do vegetarians live longer?"

Veggers, do read past few paragraphs to
Quote:
Longevity studies of vegetarians produce conflicting data. Some studies do not show that vegetarians live significantly longer.25,29 Two studies of people who consumed very little meat showed an average life-span increase of 3.6 years.39 A huge study of Seventh Day Adventists who ate little or no meat showed longevity increases of 7.28 years in men and 4.42 years in women.40 These data are confounded by the fact that Seventh Day Adventists follow healthy lifestyles free of tobacco and alcohol.
Then,
Quote:
A fascinating paper recently published in the journal Mechanisms of Aging and Development presents an entirely new theory to explain why vegetarians do not live longer.41 It turns out that those who avoid eating beef suffer a deficiency of a nutrient (carnosine) that is critical to preventing lethal glycation reactions in the body.

For the benefit of new members, glycation can be defined as the toxic binding of glucose to the body’s proteins. Glycation alters the body’s proteins and renders them non-functional. While wrinkled skin is the first outward appearance of glycation, most degenerative diseases are affected in one way or another by pathological glycation reactions.

Diabetics suffer from accelerated glycation that contributes to the secondary diseases that result in premature death.42,43 For instance, glycation’s destructive effect on the arterial system results in a loss of elasticity, hypertension, and atherosclerosis.44-47 Glycation is involved in disorders as diverse as cataract, cancer, and Alzheimer’s disease.48-57

Unless aggressive steps are taken, many aging adults will suffer the devastating effects of glycation to proteins throughout their bodies. This fact was established recently when it was shown that even healthy people with slightly elevated glycation levels are at higher risk for heart attack.

Vegetarians have higher levels of advanced glycation end products (AGEs) in their blood compared to those who eat meat.58,59 This is because an exclusively vegetarian diet would lack carnosine, nature’s most potent anti-glycating agent.

Sorry for the late reaction, but I find this interesting. Genus Homo have been omnivorous for millions of years, since at least Homo Erectus. Even if dietary science is a work in progress, it's obvious that we're adapted to eating meat. We have the teeth and the gut for it. Grain and legumes are a very recent addition to the human diet, and are not always well-tolerated. Same with dairy.

Whatever you think we should do, please don't misrepresent what we have done.

It's not pseudoscience to say that we're naturally omnivores; it's simple fact. By all means, though, feel free to propose a plan to establish an alternative, while understanding that it could take at least a few hundred thousand years to make it work.

No, I don't consume soy milk or any processed foods. I eat about 3000 calories (I'm an athlete) of raw fruit each day and a large quantity of green vegetables, mainly lettuce and celery, with small amounts of nuts, seeds, and avocados. I eat a lot of tomatoes and cucumbers. I don't eat any legumes or grains. I've eaten this way for many years and have posted about it here going way back, years ago.
I certainly agree that I'm not a biological freak for whom nutritional science doesn't apply. Yet somehow I'm not B12 deficient.

No, copraphagy isn't something I have any interest in trying. I think you're correct, that B12 is absorbable in the way you describe, and that this is very likely a viable B12 source for me as well as for other healthy people. However, some vegans do run into problems without an external B12 source, so I understand the recommendations for all vegans to supplement. But don't happen to bother with it since my levels have always been healthy even after 25 years.

I haven't misrepresented anything at all.

I don't deny that we are adapted to eat meat; I'm simply pointing out that evolution is not an ultimate arbiter of what we should do. That goes for many arguably adaptive traits that we try to avoid such as overeating, rape, racism - or other forms of them-and-us categorizing, certain cognitive biases that make sense in a hunter-gatherer society but less so in the modern age, etc...

Sure, but understanding our evolutionary history can offer insight into our biology, including what sort of diet is likely to be best from a health perspective.

It's certainly not the last word on it, and it's certainly not impossible to improve on our ancestral diet(s)*, but it's not pseudoscience to look to our evolutionary history for some insight on this question.

*That "s" is an important point, as our ancestors ate different diets at different times and places. That we are omnivores whose diet has been influenced both by environment an culture makes questions about the diets of our ancestors even more complicated.

It sounds like we are in agreement.

I didn't say it was. I said it was pseudoscience to say:

Look, we have evolved to eat this, therefore we must eat this. Evolution tells us we must. It is the ultimate arbiter!

And we have some examples of this pseudoscience such as the paleo diet which takes the premise - this is what we ate before we started up with those pesky grains and dairy products therefore we ought not to eat grains and dairy products, etc... and paleo must be optimal for health.

Really, and while we're at it, why not shun modern medicine and rely on "natural" remedies, and let's do away with hospitals and low infant mortality and literacy, and all other forms of science including modern nutritional science.

Yep, I agree with you about that.

I think paleo diets take the argument further than it's worth, but as a rule of thumb "eat what your ancestors ate" is probably useful. The problem is that they had constraints in availability so we can certainly improve on those ancestral diets: As you say it shouldn't end there.

Quote:

Sure, I understand and agree with that point. But I do think that a lot of questions of nutrition and diet are complicated enough that precise answers are hard to come by and so looking at our evolutionary history can offer insight in the meantime*.

*ETA: by "in the meantime" I mean while and until better controlled studies on diet are done.
