We did not evolve to eat any of the foods you consider natural. Corn, rice, beans, apples, pineapples - all look very, very different than the food our ancestors ate.
Don't talk to me about "what you consider natural". I do not consider those foods natural to the human diet at all, apples may be reasonably similar to what humans ate. Figs, oranges, bananas grapes are the types of natural foods humans ate.
You have that exactly backwards. Our NATURAL environment included dysentery, plague, starvation and high rates of infant mortality. Death through contaminated water and rotten meat was common. That's why we have pretty capable immune systems; our ancestors taxed them to the limit, and even then a great many died.
billyvon I'm going to be straight with you here: I will not learn anything from you, okay? You will learn stuff from me. I know anyone can say that, but I'm just trying to be honest.
Contaminated water and rotten meat were not problems for our earliest ancestors, because they lived in the savana and previous to that the jungle and ate a diet of predominantly fruit which contains more than enough water. They only needed to eat meat rarely, and they certainly wouldn't have eaten rotting meat.
The reason we are doing so well now (i.e. you can reasonably expect a child to survive to their teens) is because we screwed around with our natural environment so we could live longer and survive more reliably. We have done that by radically changing our environment, which includes what we eat, what we drink, how we protect ourselves, how we prepare food etc etc.
That's just not true. The apes in the jungle today, when not encroached on by humans, are doing far better than humans. I'll grant you that these myths persist in popular culture. However in the jungle there is fruit as far as the eye can see most of the year. There is almost no disease... that came with the start of civilization and reached a peak during the middle ages.
We are not surviving longer or in better shape due to civilization and we never have. Life expectancy only plummeted at the start of the neolithic period (ie. when agriculture came about), before that we don't know how long humans lived but if we go by how long apes live in the jungle today it would have been their full limit of lifespan most of the time.
Want to live in your "natural" environment? Eat carrion, forage for food, eat mushrooms without regard for whether they are poisonous or not. Poop in a pond and use that as your water source. Discard your unnatural house and live outside. And depending how far back you want to go, get rid of either all your clothing or any clothing not made from uncured animal skins and bark. Give birth on a dirt floor. How well are you (and your children) going to do?
They would do brilliantly, apart from some untrue rhetorical devices you've thrown in there, that is how we're perfectly evolved to live. They would get the perfect amount of exercise and would enjoy it, they would be eating only fresh, raw organic fruit. If the fruit is imperfect they would TASTE that it's imperfect and find a different one, instead of stupidly adding flavouring to it to fool their body into thinking it's good food. It's only EXTREMELY rarely that people were starving in primitive times, it's a myth that civilization has done anything at all to improve the circumstances of any of humanity. In the wild animals don't get obesity, they don't get macular degeneration, diabetes, arthritis, cardiovascular disease (some apes do when they are put on human foods, tooth decay (same as for cardiovascular disease), asthma and so on. It's so obvious it's ridiculous.
And you seem to have the standard misconception about what our "natural environment" was - that it was a utopia of free modern foods, where you picked plump ripe apples off a healthy tree and washed them down with cool spring water. It wasn't anything like that.
Oh yes it was, and you can still see it today. It's really extraordinary how much fruit you can find in a single metre square of the canopy, enough to feed someone for well over a day. Fruits also exist and are available
the whole year around in the forest, it's another terrible illusion that they're not. Apes are rarely hungry, they play with each other, have fights of varying degrees of aggression and have all sorts of social and sexual situations. They only ever start to get hungry when humans or other species are encroaching on their land.
I don't have any "standard misconception". Hardly anyone thinks it was the way I'm saying. The typical conception is of hunger and short lifespan (even though there is zero evidence for that).
We have evolved very little in the short span of last 10,000 years, but 100% of all man made changes in the food he eats has occurred since them. Almost all of our evolution took place over millions of years, prior to 10K years ago. Natural selection by the environment is a very slow process, but rare now that man has been actively selecting during the last 10K years. Look how may dog types he has created from the wolf ancestor of all in the last 10K years.
And yet there is still only one dog, he has not evoked speciation in even one animal (as far as I know, certainly not the dog), something extremely common in nature.
If you want to eat the only foods we evolved with (foods with same genes as those of more than 10,000 years ago) then you will be very hungry - no wheat, rice, bean, potatoe, corn, etc. products, none of the fruits and vegetables you find in the store, etc.
The fruits available in the store are quite similar to what primordial man ate. Humans have always selected fruits even before civilization (as have all the other apes). Artificial selection after the start of agriculture did pervert fruit a bit, but it's still tolerably similar to many wild variations of the fruit that are found in the wild today.
Man ate mainly wild tubers, some grasses, and when he could some proteins, like grubs, snakes, etc. that are easy to catch plus when his tribe got lucky a larger animal or the left overs of some tiger´s kill etc.
This is all nonsense.
Man ate mainly fruit, as do all the other apes. He ate the most delicious fruit you could imagine.
Man never ate "some grasses" except maybe when he was extremly hungry and starving.
Man also would never eat wild tubers except when he was extremely hungry and starving OR after the invention of fire. We evolved very little after the invention of fire.
