Just my opinion and based on my personal headache relief plan—avoid sugars of all kinds (in excess). I wonder if the corn to ethanol program will eliminate some of the syrup or is that a by-product?
IIRC, HFCS is genetically engineered to be sweeter than sugar, and cheaper. I think there’s a lot more to it than we know, because another thing that dramatically decreased when we controlled our diets here was the constant food cravings—another side effect of HFCS.
