In the video, Dr. Wansink discusses:
- How we can change behavior by changing the environment in which people live, work and play. People are highly influenced by the things around them.
- That even small barriers to accessing unhealthy foods give people pause to reconsider if they should eat it or not. (The same is true for drugs and alcohol.)
- The importance of "small p" policy such as putting healthy foods first in a school cafeteria. While large scale ("big P") public policy is important, small scale policy implemented in community organizations, schools and neighborhoods play an important role, as well.
