It's not as much as one might suppose. Let's see. History, functioning, and common sense/ethics.
What is the ideal human diet. That's a history question. It's whatever we were made or Evolved to use. That's the heart of the matter. (Readers familiar with these pages will understand my usage of the capital
Evolved -- it's the religion, not the
real sort of evolution, the way cars change over time because they're redesigned via intelligence to be better ... when they are.) Did we Evolve so that whatever nutrients were available, that's what we adapted to need? -- and what wasn't available we Evolved out of a need for? Or were we Designed, as by God, to need whatever it is we need -- and sometimes we get that and sometimes we don't, but it's a fixed need, with only a fixed, genetically-determined capacity for variability?
If Evolved, then the "Paleolithic Diet" is correct or nearly so -- determined by observations of what tribal, hunter-gatherer societies have access to. Because modern stone age cultures would be reasonably similar to ancient ones, from which we Evolved. If it's true, it's true. Never argue with what's true. Is it? If so, what is the evidence? The evidence is the assumption of Evolution, and the fact that hunter-gather cultures eat as they do. In other words, the argument begs the question and the reasoning is circular.
As for my own bias, it's what is now called Intelligent Design -- a disingenuous vocabulary concession to atheists and secularists. If we were actually created, by God, in a Garden say, then there would have been an ideal diet that was meant to sustain the species. We can be certain that it was not a hunter-gatherer diet, nor an agricultural one. Something else, entirely.
If this Garden was in Eden, then I can be specific. Rule One: "I have given you every herb that yields seed which is on the face of the earth, and every tree whose fruit yields seed; to you it shall be for food." Things that grow on the ground and have seeds; things that grow in trees and have seeds. Cucumbers; tomatoes; squash -- herbs that have seeds ... they are fruits.
Rule Two: "Of every tree in the garden you may freely eat. You may freely eat of every tree, but one of them will kill you." So we have free will, regarding what we may eat -- but not everything that may be eaten, should be eaten. Diet affects our health. You heard it here first. What then was, oh, say, let's call him
Adam, designed to eat? Tree food, ground food, with seeds. As it were, fruit. Coincidentally, fruit and berries and less obvious fruits are designed, unlike virtually every other food, to be eaten. That's the deal the plant makes:
you can eat my fruit if/because you spread my seeds. Pretty clever, eh?
Leaves are meant to convert sunlight into sugar, and may be eaten. Vegetables are meant to be the body of a plant, and may be eaten. Roots are meant to pull up water and minerals, and may be eaten. Tubers are meant to store energy for the plant, and may be eaten. Grains/seeds/nuts are meant to grow into another plant, and may be eaten. Flesh is meant to be the body of an animal, and may be eaten. Eggs and milk ... well, you know. Whoever it was who wrote all those fairy tales in Genesis at least had a good idea about what fruit is for.
Mankind was designed to eat fruit. That was the original perfect diet. Not Paleo ... Edenic. Cucumbers, tomatoes, melons, pumpkins, lychee nuts, dates, chili peppers, nuts -- they are fruit. What, you were thinking apples? Alas, the world since that distant age has changed. We did not change with it. We have the same needs as always, but not the same resources nor even the same world.
First, the Fall. Mankind no longer has access to the original menu. Rule Three: "You shall eat the herb of the field." Behold, the invention of agriculture. Adam the orchard-tender becomes a farmer. Hunter-gatherer? It is a degenerate state. It did not come first. It is a result of the Fall and the Flood. Agriculture was an ad hoc response, an adaptation to being kicked out of Paradise. Still plant-based, but second-best. Well, we know that anyway, because too many carbs/grains will make you fat.
Then, the Flood. Neither Fall nor Flood affected our genetics, but they did affect the expression of our genes, and they did effect our environment. The ideal startup conditions were not sustained. The Garden perished. After the Flood, essential nutritional resources became rare or extinct. You've heard about mass extinctions. Evolutionists did not invent the idea. Go to your local library and find a Bible there and read all about it. I think you may find it online. The Bible? Genesis? The Flood? Mass extinctions.
Rule Four: "Every moving thing that lives shall be food for you. I have given you all things, even as the green herbs." The entire biosphere of the planet was disrupted by the Flood. There was no agriculture just after it, because all there was were mudflats and growing iceshields. What to eat? Immediately, animals, who could scavenge on debris. I go into it in great detail, in
Dragons in the Earth. (You think you see objections. I have anticipated and answered them.) Point is, we eat meat because we can, especially in the absence of something better. And some better things are absolutely absent. Mass-extinctions, remember? Who can say what nutritionally perfect fruits and herbs and seeds and mushrooms are now extinct. Who can say how much longer we'd live, with vibrant health, if these lost but essential nutrients were not lost. The pre-Flood patriarchs lived so long, as I think they did, for a number of reasons. One of them would have been a diet inaccessible to us.
Theory, yes. But so is Evolutionism. We decide by the evidence, not by the dogma. What's that you say? -- the Bible is all dogma? Well ... that would be
your religion. Maybe you're right. Maybe we came from monkeys and shrews and lizards and fish and germs and inorganic matter that was stuck by lightning. Sounds like a theory to me.
So that's history. Either we Evolved on a hunter-gatherer diet of grubs and sap and roots and lizards and monkeys and bark and mold and algae and salamanders over the past several hundred thousand years -- and I haven't detailed that because you know that story already -- or we were designed, etc. Both assumptions require that there be an ideal human diet, optimal for health and performance. The former suggests that such a diet is reproducible. The latter, in my iteration, says it cannot be reproduced, but diet can still be optimized within existing if irreparable limits.
If I'm correct, then a purely vegetarian diet seems likely to be best. Only those necessary nutrients that can no longer be found in plants should or could come from animals, if any. Are there any? -- any essential nutrients that can come to us only via animals? Well, vitamin B-12? But that's from a bacteria, and only secondhand through animals. Even so, if that's it, that's it. But they say it's in Brewers yeast. So that's it. Anything else supposed to be unique from animals? Omega-3? Well, yes and no. We make it ourselves. But the health benefits are very real indeed. Someone with an ideal diet, however, wouldn't need to supplement with fish oil. So my theory would have it. Anything else? You'll have to tell me.
The rest of it, functioning and performance, and common sense and ethics, well, these are easy. Whatever works.
The China Study tells us that animal products are powerfully correlated to degenerative diseases. That's functioning. Performance is a more difficult issue -- my son is looking at it right now, or will be. Common sense? Yeah, it's good to eat something that will kill you if you leave it in the sun too long. Something that stinks to make you puke is
really good food. The deader the better in fact ... put hair on your chest ... make you strong like bull! Ethics? Let me kill you and eat your body because, well, because I like the way you taste. Yum.
It may be that my son's experiment demonstrates, conclusively, that animal flesh, its "high-quality" protein, results in better performance. I won't be able to argue with that.
No, you're not performing better? This wouldn't say anything about Evolution or Design, since extinction confounds the matter, but it would prove that meat is good, somehow, dammit. But that's getting ahead of ourselves. On the other hand, if a plant-based diet results in better performance, then the Paleo/Evolution diet is invalidated. If my logic is wrong, please inform me.
(No one is suggesting that an extinction of food-animals is a relevant factor; it would be an ad hoc invention to save their theory. The presumption is that we would continue to Evolve, with extinct food-sources replaced by our newly Evolved capacity to utilize other sources. For once, Evolutionists would be trapped by their own malleability. But of course they wouldn't be. Since Evolutionism is true, it can't be falsified. Only theories can be falsified, and Evolution is a fact. Stupid. Didn't you know that?)
What do I know about diet? I know there is a lot of nonsense involved in the whole area. Lots of emotion, lots of extremely shoddy thinking. I know diet is a profoundly religious thing. I know that physically I'm not like any other 50 year old you've ever met, and the greatest likely factor in this is my own diet, vegetarian for 30 years. I know that disease has a number of causes -- bacterial and viral, genetic and chemical -- but that the major cause of disease in our own culture comes from a diet that is nothing but slow poison. Too many carbs, and too much animal stuff.
So, does it matter, all this talk about apemen and Eden? Matter in some way other than philosopho-religio-theoretically? Yes, it matters insofar as it opens or closes our minds to what is best for our health. False assumptions might lead us to healthful conduct. True assumptions seem more likely to. But anything that closes our minds to behavior that would improve our lives, well, that's a thing to be avoided. I spent 32 years, man and boy, as an Evolutionist. I spent 19 years mostly boy, as a Flesheater. I can make a case that evidence can change my mind. Regarding religion, the results aren't in. Maybe Jesus was wrong. But as for health and performance, well, you must know by now how radiantly beautiful I am, and how unbelievably powerful, and so manly, and virile and so desirable to all the chicks, and did I mention beautiful yet? Cuz I am, beautiful. Just beautiful. Ah. And blond and tall. That's my hotmail address, hottallblonddude4u. So that proves it then.
Rule Five: "You may freely eat of every thing that you can fit into your mouth and swallow, but many of them will kill you, fast or slow." (See Rule Two.)
