The link mentioned above is Robert Lustig MD's talk entitled "Sugar: The Bitter Truth". I found it very interesting and quite convincing, but beware that it's long (1.5 hrs) and you have to be willing to sit through a lot of biochemistry, since he goes through a bunch of cellular metabolic pathways in gory detail. If you don't care about the biochemistry, the parts about how everything we "know" about nutrition is based on shaky ground (e.g., the FDA's food pyramid, "fat in the diet is bad", etc.) is well worth watching, as is the history of how the amount of sugar in the U.S. diet has been dramatically increasing (e.g., the steady increase in the serving size of Coca Cola since 1915).

This is a great video. I watch it once in a while when I need to cut down on my ice cream.
