Fructose is fructose, there's no "natural fructose" however it's one thing to eat it pure, another one in a fruit That I can buy. What I'm more skeptical of is that there's a distinction between "manufactured" and "natural" fructose once both have been concentrated and are used as additives to sweeten other products. Eating a pear is one thing, but I'm less sure that a "naturally sweetened" product which has been sweetened with concentrated pear juice or a similar fruit-based sugar extract is really more healthy than the same product that has been sweetened with more conventional "manufactured" sugars. I don't doubt that eating an actual fruit is almost certainly better than either one.
