News: 1/2 of US Adults will be Obese by 2030?

I stumbled on this article today in the Washington Post: Half of U.S. adults will be obese by 2030, report says. I don't know what I'm more shocked by, the fact that we might be headed in that direction, or the fact that this report advocates making "healthful foods cheaper and less-healthful foods more expensive largely through tax strategies".  Ugh.  I just hope that if our government ever implemented a tax strategy like that, they would at least have the sense to NOT put beef and eggs in the "unhealthy" category for once.  Grrr.
