Americans have the cheapest food in history, and that unprecedented abundance is largely responsible for why we’re so fat.

According to a new article in CA: A Cancer Journal for Clinicians, Americans in the 1930s spent a quarter of their disposable income on food. That share has fallen steadily through the decades, to the point where today less than 10% of Americans’ disposable dollars go for food. (That varies across income groups, of course: The poorest 20% of Americans still spend about a third of their disposable income on food.)

And even as the real cost of food goes down, each dollar we spend buys us more calories than it used to. The average American’s total caloric intake (adjusted for spoilage and other waste) rose from 2,109 calories in 1970 to 2,568 calories in 2010, according to U.S. Department of Agriculture data — the equivalent of an extra steak sandwich every day. Little surprise, then, that more than 78 million U.S. adults, or 34.9%, were obese in 2011-12 — more than twice the rate found in a 1976-1980 health survey.

It’d be nice to think that all we as a people need to do is exercise more and eat more fruits and vegetables. But as the authors of the new paper point out, we’re already doing that: 51% of people in a 2009 study reported exercising regularly, up from 46% in 2001. Americans, as a whole, also ate more fresh fruits and vegetables in 2010 than they did in 197o (though again, that varies considerably among different groups). “[I]f people had access to more produce or cheaper produce, or just ate more of it, would they eat less candy and be thinner?” the researchers ask in conclusion. “Probably not.”

The problem lies NOT in how cheap food prices are BUT in the lack of real food culture in America where citizens spend more money on fast food when they can feed themselves on real food for less. When most Americans today couldn’t care less or have no clue about how their food is prepared is a sure sign that the future will be problematic for many (in fact, it’s already happening). But the theory is not valid when you look at many other countries and cultures where food is cheap and the citizens are healthier. The only difference is the presence of a strong food culture in these countries where people know more about real food and less about fast food (unless you are talking about healthy and quick stir-fry). You will also find that, in these same countries, there is an absence of powerful agri-business that influence or control their food culture – NOT the same reality we face daily in North America. – Leo B.
