Some of the myth descriptions are tough to stomach, so to speak, although the myths themselves are not the worst I've ever read. They are:
1. People in poor neighborhoods lack access to fresh fruits and vegetables
2. Advertising forces people to make unhealthy choices.
3. Eating healthy is too expensive.
4. People need more information about what they eat.
5. There are too many fast-food restaurants in low-income neighborhoods.
The worst myth is #4. The author's point is that calorie information will not deter us from eating bad stuff. But I would argue that calorie information is not the information we need to know. What's the food made of, ingredients, and such? THAT we DO need to know, myths author...
All facts can be said to be myths (myth as "not true" is specious per se) but not all myths are necessarily facts.
Item 2: Advertising "forces" nothing.
Item 4: There's plenty of accurate, useful health information available. Availing oneself of the information is a choice. Human nature is a "some assembly required" deal. Pretending this is not true is an established human pastime.
Item 5: There are too many fast food restaurants, per se, everywhere. Including Beverly Hills.
Myth to #1, #3, and #5, but only because people don't make the effort to spend money on food. It's not a myth that people have screwed up time preferences.
Myth to #2, of course, there's no force in advertising.
Some truth to #4... People need to know how shitty the processed food they're eating is. Their ignorance hampers their health. Again, it's a matter of effort on their part to educate themselves. Less so than a failure to disclose all the facts.
