In my face-to-face class, we read a chapter from the book The Economics of Public Issues on how Americans have been gaining weight. It mentioned that food has gotten relatively cheaper over time and we lead more sedentary lives. But there was an interesting article in The Washington Post recently. The author, Tom Wolfe, says you don't have to spend much to eat healthy. Here is part of what he said:
"I began adhering to a $25 weekly food budget in early April specifically to test the economic feasibility of living on organic whole grains, dried beans and fresh vegetables. On that $3.57 a day, I have been able, through careful planning, to feed myself well -- with enough left over to prepare lunch four days a week for the five people on the staff of my store. Virtually my entire diet since April has been grains and beans grown certified-organic and a mix of organic and cheaper non-organic vegetables."
