But that's not the real problem with high fructose corn syrup. The bigger issue, which the industry neither can nor particularly cares to rebut, is that the product exists at all. We pump absurd quantities of cash into subsidizing corn (we also have a huge tariff on Brazilian sugar cane, incidentally). Over the past 10 years alone, Congress has appropriated more than $50 billion to encourage farmers to grow the stuff. But people don't want to eat $50 billion in subsidized corn. And if the cobs just sat around developing mold, Congress would cut off the spigot. Enter high fructose corn syrup, which sucks up the subsidies and created a world in which calories from a sweet, highly caloric additive have become the cheapest of all energy sources. That's the primary way the syrup contributes to obesity: Not by being more fattening, but by being so heavily subsidized that it makes it far cheaper to sustain yourself on sweetened carbohydrates than on nutritious food. That might be fine if the sweetener were naturally cheap, but instead, taxpayers are funding a concerted effort to flood grocery stores with unnaturally cheap, utterly unhealthy, foods.
Nothing more to add, there.
