It doesn't matter, they say, whether that calorie comes from table sugar (sucrose) or HFCS.
HFCS contains at most 55 percent fructose and in some forms only 43 percent; almost all the rest is glucose.
Soot, methane, ozone, and HFCS are a lot less sexy than flying to Rio and making bold promises.
When HFCS is made from cornstarch, the fructose molecules are not bound to other sugar molecules.
Such differences may explain the effects of HFCS in both lab animals and people.
That suggests that HFCS may be partly responsible for the obesity epidemic.
Treating fructose as a stand-in for HFCS might not be a bad approximation.
