I saw that we have an ongoing thread for Paleo quotes so I thought it'd be cool to have a place to put new Paleo articles that come out. Especially easy to digest ones such as this Reuters article.
Reuters: Cancer Cells Slurp Fructose. (Fruit would have only been seasonal to hunter-gatherers so they naturally would have had a limited fructose intake).

You should be as skeptical (if not more so) of science that agrees with your own prejudices as ones that disagree.
That study Reuters: Cancer Cells Slurp Fructose dose not really indicate anything at this stage. Its just a bunch of cancer cells grown in a dish being fed different pure sugars.
I think that if someone produced a similar study showing that saturated fat is bad because it poisoned some pancreas cells grown in a petri dish it would not be looked kindly on here.
Try this for a more reasoned view of what the study actually showed: Fructose and pancreatic cancer
As I mentioned before, there very well may be legitimate, science-based reasons to be worried about fructose and high fructose corn syrup. Steve Novella recently wrote a good review of the topic in which he wanted to point out that glucose and fructose are sugars, as is the main component of high fructose corn syrup. It's a high calorie, highly processed substance that has no other nutritional value other than as pure fuel. What Heaney's study doesn't really answer is just how different from the case in normal pancreatic cells is fructose metabolism in pancreatic cells or if it's even different? In the current study, HPDE6 cells, which are a cell line derived from normal pancreas cells, behaved the same as all the pancreatic cancer cell lines. Fructose supported its growth and was used primarily for ribose and nucleic acid synthesis.
There's a lot of hard work that needs to be done to validate the cell culture findings reported by Heaney's group, not the least of which is testing it in animal models. It's far too early to make any sort of recommendations about high fructose corn syrup and diet based on this study, and Heaney should have known better. Next up, I can see an article on NaturalNews.com touting this study as "proof" that high fructose corn syrup is pure, concentrated evil and that food manufacturers are out to kill us all, and Heaney will have given Mike Adams some choice quotes to use for that article.

Here's another one. Standing during the day reduces early awakening. It is theorized that we evolved to optimally live by spending much of our time on our feet everyday.

Fruit certainly isn't seasonal in the tropics.

Here is an article, I hope it belongs here in the right place (if it's not I apologize). It is in the Washington Post, "Potatoes Bad, Nuts Good". http://www.washingtonpost.com/national/health-science/potatoes-bad-nuts-good-for-staying-slim-harvard-study-finds/2011/06/17/AGRWmIgH_story.html?fb_ref=NetworkNews
Seems to support Paleo eating...
