Behavioral Nutrition

It seems a new term to Blattman, who blogs:

One of the more unexpected lessons: if you are hungry in the middle of the afternoon, eat. You’ll have more energy, be less irritable, you won’t overeat and dinner, and you’re less likely to break down and gorge on Reese’s peanut butter cups.
The key: don’t call it a snack, call it a second lunch; you’ll hold yourself to a higher standard and are more likely to eat healthy.
Behavioral nutrition?

but few of our consumption decisions are more affected by psychology, framing effects, procrastination, hyperbolic discounting, and other behavioral economics staples than those about food and nutrition. Change.org mentions a growing realization that marketing is needed on the side "good" too:

Bolthouse Farms and nearly 50 other carrot growers are spending $25 million on the carrot industry's first-ever marketing campaign, which will use flashy ads and packaging to encourage kids to reach for baby carrots instead of a bag of chips.

The notion of "comfort food" can be made to fit into a standard utility framework (e.g. certain foods have a stochastic component whose realization is usually low but is sometimes very high) but this isn't regularly done or accounted for.
