Who spend little more than 15 percent of their income on food, people in less developed countries sometimes spend up to of their total income to feed their families.

Like Kiera—and, I'm sure, many of the readers of her article—I was a bit shocked when I calculated how much I spend on food. I like to think I'm thrifty in my food spending habits—I cook a lot and usually eat out only on the weekends—but I don't usually add up my food costs and rarely make serious estimates for food spending when I make a budget, instead assuming that I'll manage to make do with whatever's left after I cut a check for rent, buy a bus pass, and pay my utility bills.
