anthropologist at Texas A&M University who led the excavation of the Hinds
Cave deposit in the mid-1970s and provided Dr. Poinar with the samples.
The cave, an enormous, very dry, cliff-face rock shelter, housed generations
of hunter-gatherers for 9,000 years. The site has yielded more than 2,000
cow-patty-shaped human coprolites.
The shape of these coprolites is due to the "astronomical" amounts of fibre
in them, Dr. Bryant says. He estimates that the Hinds Cave inhabitants ate
15 times the daily fibre intake of present-day North Americans, mostly in
the form of roasted desert plants, including agave and yucca.
Using mitochondrial DNA analysis, Dr. Poinar showed that three coprolites
belonged to separate individuals. And he confirmed Dr. Bryant's microscopic
analysis of the contents: These paleo-peoples were eating well.
Through genetic reconstruction, he showed that in the 24 to 48 hours before
relieving himself at the back of the shelter, one Hinds Cave resident had
eaten a veritable Thanksgiving feast. The coprolite included evidence of
pronghorn antelope, cottontail rabbit, packrat, squirrel and eight types of
wild plants. ....
How exceptional is that site? Were other paleolithics eating less fibre than we do and less that one-tenth or one-fifteenth of that of the people of this site? Not likely. More likely is that the paleolithic diet generally contained multiple times the amount of fibre that ours does.
How does the above compare to 150 mg per day? There following article suggests up to 300 g per day (yes, grams, not miligrams):

Hi Jim
Well - I'm no expert so, no, I probably can't help you understand it better. Dr Mercola might (http://articles.mercola.com/sites/articles/archive/2013/11/25/9-fiber-health-benefits.aspx) haha... But that doesn't explain my original question of where the 150 mg per day of fibre did come from in our ancestors!! Or where that figure even came from?
Best wishes
Tracey

Hi Tracey. Merry Christmas from Texas. I don't understand the value of dietary fiber. Can you help me understand? Great to see activity in this list. Jim Swayze
