Erm, we just killed the food pyramid which was held up as a standard of health for 30 years. Are you sure you want to enact bans on what the government thinks is unhealthy?

There are a whole bunch of materials in the natural world that we just assume are safe because they've been around 'forever'. If you're going to use science as your standard for bans, there are billions of dollars of tests to do.

There's some dark math to be done on the benefit of a human life vs the cost of saving it. Maybe ten guys drinking infinite soda are keeping 100 at work in soda companies, providing for their families.
