One of principal arguments food corporations have used to defend high-fructose corn syrup (HFCS) is that it is chemically similar to table sugar.
Manufacturers have stated repeatedly that HFCS contains at most 55 percent fructose, little different from white sugar's 50 percent fructose makeup.
But as it turns out, the specific amount of fructose in HFCS for any particular food product has never been officially tested. And when researchers tested brand-name sodas, they found that the fructose content is actually 65 percent.
According to Grist:
"Why is this important?
It's because research has shown fructose to be particularly harmful to human health. Unlike excess glucose, which passes through our digestive tract and is excreted, 100 percent of fructose that's consumed is taken up by the liver. Once there, fructose causes increased fat deposition in the abdominal cavity and increased blood levels of triglycerides -- both of which are risk factors for heart disease and diabetes."
