How did nature make human body so vulnerable to carbohydrate?

Blue! Interesting. If the preagricultural foods tended to be smaller, wouldn't the hunter-gatherers have consumed less when they found them? Wouldn't there discoveries of such things have been rather hit-or-miss? (I still haven't cracked open my books.) Nah, people remembered where and when to find good crops of different foods. Even nomadic people made sure they were in the right place at the right time to find lots of good stuff. Oh, of course, but they did not control how much of that food was there any given year--and what was there may have been shared. Did you know that in South America the mountain peoples (don't ask me their names, I can't remember) used to freeze-dry potatoes? They'd dig them up, then leave them on the ground overnight in a frost. The next morning they'd stamp on them to flatten them, and leave them out overnight again. Repeat the procedure a few times and you have freeze-dried spuds that can be stored for a whole winter. That sounds vaguely familiar, but I forget who it was. -- Jean B. |

Oh, of course, but they did not control how much of that food was there any given year--and what was there may have been shared. That's true enough. My point, though, was they knew when and where to find it. Not knowing was almost certain death. Crops still fail, occasionally. How much food there is available is not _entirely_ under the control of humans. Miche -- If you want to end war and stuff you got to sing loud. -- Arlo Guthrie, "Alice's Restaurant" |

Dangerous to harvest, but it must have been much prized. Remember, our ancesters were hunter-gatherers. They gathered from the plants that grew naturally. Right. And some of those plants were high-carb (including the aforementioned root vegetables). For those wanting cites, here they a From one friend who decided to have a look into SE Asian wild rice: "Banyan Valley cave dated 3500 bc at the lowest levels. 110 rice husks recoverd. when compared to cultivated and wild varieties theses were all caracteristic of wild varieties ( no awn on the tip of the grain sheath and ragged surface of husk). The Archaeology of Mainland South East Asia, Charles Higham, Cambridge University Press 1989" From another friend who does research into ancient civilizations for fun: "_Domestication of Plants in the Old World_ Daniel Zohary and Maria Hopf. One example out of many: Ohalo, an Epi-Palaeolithic site in Israel, dating to 17,000 BCE. Remains include wild wheat and barley, and also acorns (which are quite high in starch; more on that below). These are all wild plants, as the earliest dates for wheat and barley agriculture are 8000 BCE. Wheat is described as 60-80% starch in the same book, and that holds true for both wild and domesticated wheats (in fact, much domesticated wheat is higher in protein and therefore lower in starch) and also the book states "Einkorn wheat was,,,, extensively collected from the wild before its introduction into cultivation." Acorns. oooo, acorns. Acorns are the original high-starch food in many places, and they are always wild. "Acornutopia? Determining the role of acorns in past human subsistence" from _Food in Antiquity_ edited by John Wilkins, David Harvey, & Mike Dobson. Some bits from this article: Acorns have been found at sites in Europe datiing from 19,000 BP; acorns were used up till the present day in many Native American cultures, not least the Californian Indians." And from my DH: "Contemporary wild tuber with high carbs (even by modern standards) http://scholar.lib.vt.edu/theses/ava...121198-155735/ so wild foods can be high in carbs. neolithic Maori exploitation of cabbage tree (southern Maori not horticultural) = lots of sugar: http://www.handsonhistory.co.nz/pre-maori.htm http://www.ccc.govt.nz/parks/Trees/protected_20.asp Assuming you conflate horticulture and agriculture, which is technically a no-no but this is the internet, the sweet potato Ipomoea batatas seems be descended from the wild Ipomoea trifida, while the roots are not normally as abundant they are still a source. http://ss.knaes.affrc.go.jp/sporf/no05/m2.html Rice - putting aside the evidence of rice cultivation exceeding 10000 years Before Present http://www.carleton.ca/~bgordon/Rice....htm#EVOLUTION and the argument that humans adapt as well (domestication not being a one way street) so we've had plenty of time to adapt to this (if adaption was required, if it wasn't then we're suited to eating the food anyway) and focusing on the gathering of wild Oryza rufipogon. given there is archaeological evidence for wild rice gathering (google searches for 'archaeolgical "wild rice gathering"' or 'archaeologcial "gathering wild rice"' provide a start) this can be demostrated to have been part of the diet. Like most species it will be more important in areas it is common. Now the Alawa of the Northern terriotories Australia traditionally (i.e. non-Agriculturally) use Oryza rufipogon which can be coooked and stored for years. http://sites.uws.edu.au/vip/listerp/tbot.htm (also on that page: Screw palm (Pandanus spiralis) seed. The kernel within the seed is edible but difficult to extract. It is apparently high in oils and carbohydrates and highly sought after by people in the Top End.) Macrozamia nuts (see Cycads more generally), aside of being the greatest cancer forming agent in the natural world if not detoxified, were the major carbo source in parts of australia http://www.aiatsis.gov.au/lbry/dig_p.../a334583_a.pdf this article has figure of food production 1400 kilocalories per woman hour of processing. see also: http://aoi.com.au/acotanc/Papers/Mas...hor-n-Text.htm http://plantnet.rbgsyd.gov.au/PlantN...d/ethnaus.html " Miche (bowing out of this thread now) Don't bow out before I tell you I'm impressed. I look forward to looking at some of those links tomorrow. -- Jean B. |

You said your source was your husband, so that led me to believe that your husband must have some expertise in this field. I apologize if I was incorrect in that assumption. |

What percent of their diet would you say was carbohydrate? |
