In the presentation (45:00) he walks through the metabolism of 120 calories of glucose (from white bread), alcohol (a shot), and fructose (orange juice). Not pretty.
Doing a quick lookup in the dietary app on my phone says that 8oz of orange juice (from concentrate, with pulp) has 28g of sugar and 0g of fiber. Meanwhile a cup of raw orange (peeled) has 17g of sugar and 4g of fiber.
Based on the presenter's description of the ratio of fiber to fructose in raw fruit, I'm starting to wonder if ANY commercial juice could provide enough fiber to counter-act the fructose. I guess you could add a fiber mix or something to the juice to match the fiber/sugar ratio of the raw fruit. I personally hate the taste/flavor/texture of mixin fiber and would rather just eat the fruit.
PS. Just saw kingkongreveng_'s comment about modern fruit being bred to contain more fructose than in the past (http://news.ycombinator.com/item?id=1008261). In that case the juice is even worse than my comparison makes it look because the sugar content of modern fruit would skew the baseline upwards.
So would the occasional glass of orange juice actually be worse than the occasional can of soda? If the orange juice is mostly fructose, wouldn't the soda with 50/50 glucose-fructose be better (seeing as it at least has glucose in it)?
Also, I would think that the pulp contributes fiber, no? That's why I added 'with pulp' (in addition to the fact that I like my orange juice heavy on the pulp).

I don't think so - didn't he say orange juice is filled with sucrose? Sucrose is 50-50 glucose-fructose, unless I misinterpreted that part of the video. HFCS, as I recall, is 55-45.
