High-fructose corn syrup damages the body in multiple ways. It’s not damaging only because it is made from corn or that is made from genetically-modified ingredients, although these are certainly factors. Fructose can actually help cause diabetes because it promotes insulin resistance. Fructose is metabolized by the liver and is far more likely than glucose to be metabolized as fat in the liver. This can lead to non-alcholic fatty liver disease (NAFLD). NAFLD in turn leads to insulin resistance which promotes Type II diabetes. So, high-fructose corn syrup and fructose in general is not only unhealthy but damaging, and should be avoided in the diet as much as possible.
