General Discussion / Re: What level of fructose/sugar/fruit consumption is safe?
« on: May 25, 2012, 06:28:03 pm »Although not all wild fruits are as big and sweet as our modern cultivars, at least some are, and certain varieties even surpass our deliberately-bred fruits in size and flavor. Nature—especially with selection pressure from other fruit-eating creatures—is perfectly capable of producing sweet (and sometimes massive) fruits without human intervention. It seems unlikely that early humans only ever encountered berries or other “small, bitter” fruits, and avoiding sweeter fruits on the basis of evolutionary history may be misguided.http://rawfoodsos.com/2011/05/31/wild-and-ancient-fruit/
Based on the limited research we have, wild fruits aren’t considerably different from cultivated fruit in terms of carbohydrate content, fructose content, or fiber content. Both wild and cultivated fruit seem to average around 90% of calories from carbohydrates, and have a sugar composition that yields roughly equal parts glucose and fructose. And both wild and cultivated fruit can be relatively high or low in fiber.
Although berries are often lauded as being lower in fructose compared to other fruits, from a calorie/energy standpoint, this just ain’t true!
Early humans may very well have had access to fruit for most or even all of the year. The fruiting seasons we witness in cooler climates—with most fruit appearing in the summer—doesn’t necessarily apply to our evolutionary homeland closer to the equator.
So there had been lots of big sweety wild fruits in ancient and paleo times. On average - 50% fructose and 50% glucose. Those fruits had been the main source of carbohydrates for humans.
It's also not true that they were only a few months a year - the vegetation was all year round
