A healthier version of Coke?

I am not talking about Coke Plus here. Yesterday in my econ lecture, our professor told us that Coke in the United States uses high corn fructose syrup instead of sugar in the production. That's why Coke is so much cheaper in the States than in anywhere else ( The high demand is of course another factor. ) and it tastes different from other countries' versions as well. But the issue is high corn fructose syrup is said to be very unhealthy to our body. I have heard reports saying that high corn fructose syrup leads to faster blood sugar rise after being absorbed by our body than sugar. And this dramatic up and down will lead our body to crave for more sugar in a short period of time. That's why some people say that high corn fructose syrup is the reason behind obesity and other weight issues. I do not know if that is true. But it is probably a good idea to cut back on Coke before I go home where they have the "healthier" version of coke...
