The Fructose Index is the New Glycemic Index
I stumbled upon an interesting editorial recently in the American Journal of Clinical Nutrition from Dr. Richard Johnson's group, entitled "How Safe is Fructose for Persons With or Without Diabetes?" It was a response to a meta-analysis in the same journal pronouncing fructose safe up to 90 grams per day. That's the amount in eight apples or four cans of soda. Not quite what our hunter-gatherer ancestors were eating! The editorial outlined the case against excessive fructose, which I feel is quite strong. That led me to another, more comprehensive paper from Dr. Johnson's group, which argues that the amount of fructose found in a food, which they call the "fructose index", is more relevant to health than the food's glycemic index.
