The government taxes sugar heavily, and subsidizes high fructose corn syrup. As a result, most sodas and many other foods use HFCS instead of sugar. A lot of people eat or drink the stuff without being aware of the consequences.
No, you don’t have to drink soft drinks or other prepared foods. But the government makes it hard to avoid.
