Interesting indeed. Ellen Satter has written a hierarchy of food needs which looks like this:

This hierarchy is a response to people who argues that poor people choose to not eat "healthy food because they're ignorant or prefer unhealthy food". This hierarchy which is based on Maslows Hierarchy of Needs shows that:

"getting enough food to eat is the most important thing to people. Having food be acceptable (e.g., not rotten, something you are not allergic to) comes second. Once those two things are in place, people hope for reliable access to food and only then do they begin to worry about taste. If people have enough, acceptable, reliable, good-tasting food, then they seek out novel food experiences and begin to make choices as to what to eat for instrumental purposes (e.g., number of calories, nutritional balance)."

This is very interesting, however I do think the scale is simplifying the food issues which exist in today's world. But even so, the truth is that most of you reading this are probably on the top of the scale (how lucky are we) but have food behaviours that fits into the bottom two levels on the scale.

Think about that son.
