One thing to be aware of, before using this study to justify anti-corn syrup hysteria, is that fructose is not the same as “high fructose corn syrup”, and glucose is not the same as sucrose. HFCS has pretty much the same amounts of fructose and glucose that sucrose does. So if you think that drinks made with sucrose rather than HFCS will not display the same effect described in this article, you would be mistaken.
That 's not necessarily so. Before I checked into it I used to believe that too. Soft drinks are supposed to be 55% fructose, 42% glucose and 3% other sugars. 56:42 is the same as 4:3, but the actual HFCS can be as high as 65% fructose.
The fMRI study showed differences between pure glucose and pure fructose in cerebral blood flow. The hormonal studies explain why fructose does not promote a sense of feeling full.
