Well, most of us know that but few of us do that. However more research came out last week about how bad sugar is for you and here is an article by Dr. Robert Lustig about sugar. He also touches on the argument about not all calories being the same.

Research has shown that doesn't work. Dr. Lustig was on local talk radio over the weekend and discussed this misconception and why it doesn't work. Part of it has to do with not all calories being the same. Radio show (Lustig is on at around 33 minutes): http://www.kgoradio.com/common/page.php?pt=Pat+Thurston+Podcast&id=4372&is_corp=0
