I was under the impression that most of the carbs in winter squash (including butternut) were from starch. NutritionData doesn't break it down totally, but only shows 4g/21.5g as sugar. I know that the carbs in non-starchy vegetables like lettuce are mostly from sugar. Maybe that's what Paul is referring to. Also, I'm not sure if the sugar in vegetables is fructose or what.... just checked ND again. Romaine lettuce has 390mg glucose and 800mg fructose (+2.1g fiber) per 100g (which is a LOT of lettuce). So yeah, I guess veggies do provide more fructose than glucose in general... probably, heh.
