Princeton researchers find that high-fructose corn syrup prompts considerably more weight gain
From the summary:
This creates a fascinating puzzle. The rats in the Princeton study became obese by drinking high-fructose corn syrup, but not by drinking sucrose. The critical differences in appetite, metabolism and gene expression that underlie this phenomenon are yet to be discovered, but may relate to the fact that excess fructose is being metabolized to produce fat, while glucose is largely being processed for energy or stored as a carbohydrate, called glycogen, in the liver and muscles.
This seems consistent. For the long story on how the body metabolizes fructose and glucose, see my previous post on Sugar. Once again, a long video, but worth the journey.
What’s interesting here is that people have long considered HFCS and sucrose (sugar) to be more or less equivalent in terms of metabolic processes. This study suggests this might not be the case.
