Kolbert, reviewing The Fattening of America by Eric Finkelstein and Laurie Zuckerman, notes that food has gotten cheaper relative to the other goods and services. And fatty foods have gotten a lot cheaper. The price of soft drinks, for example, have dropped by more than 20 percent, and they now account for seven percent all calories in the US.No. Soft drinks are not examples of fatty foods. Soda has no fat at all!
If you do want fattening food, you can now get ratings of fast food in calories per dollar. Seems sensible to me. I wish grocery stores would have that, along with the unit pricing.
