The second hour of today's On Point on KSTX (FM 89.1) has a good conversation about measures taken to combat the obesity epidemic. It features Oklahoma City, but touches on many of the initiatives that San Antonio adopted with the same CPPW grant that started the Food Policy Council.
Apart from the noise about whether the government should or shouldn't tell people what to eat/drink (NYC ban on large sugary drinks for example), Tom's guest made the very good points that (1) processed food has drastically changed in the last several years, in ways that our bodies are not equipped to metabolize, and (2) changing the food environment assists people in "making the healthy choice the easy choice" as we say.
Be honest-doesn't your own consumption often depend on what someone puts in front of you?
