I'm not sure about bans, but I wouldn't be surprised to see warning labels becoming required on foods that are tasty but terribly unhealthy. It might be a way to change behavior slowly over time. Activities with a high risk of physical injury are more difficult. For things like extreme sports, the relatively small number of participants might mean that the net increase in health care costs in negligible. For activities like motorcycling that have relatively large numbers of participants, mandatory supplemental medical insurance is an option. It's probably already a good idea to have it right now, even when you aren't required to. This is another slippery slope, though. If motorcyclists are required to have extra insurance to cover medical expenses, they'll inevitably ask "why us, and not skydivers, scuba divers, etc?". It would be difficult to know where to draw the line.
