Earlier quoted context omitted.
Aside from naturally occurring micronutrients, fruit juice isn't that different from soda. I'm not a chemist, but I think it's largely just different ratios of sucrose/fructose/glucose.
Does the fiber in the fruit negate the cancer risks? If not, would it be logical to say fruit is now linked to cancer?
Pure speculation, but: I imagine the processed nature of the fiberless fruit juice (with all the other ingredients/preservatives/crap they add into it) adds to the cancer risk. I'd also guess that were one to juice the fruit themselves, that would be better than the processed kind, but you're still drinking liquid sugar and bypassing the benefits of ingesting fruit in the first place.
