Fructose can't be used by cells directly - it does not effect blood sugar levels, because it has to be processed by the liver into glucose first.[1] The potential issues with fructose are related to the matabolic processes which convert it into glucose, which is what your cells actually use. So eating say, straight fructose in fact won't spike your blood sugar since it has a much more convoluted metabolic path to consumption. Something like HFCS is more likely to be a problem because the glucose content is not in the dissacharide form of sucrose and can be directly absorbed.
