It's hard not to spend too much time at the dinner table during the holiday season, getting fatter on our way to the poor house. Though we are lectured constantly about eating right, most of us don't. And the reason, it seems, is more a matter of economics than self-indulgence.
Eating right, new research shows, is getting so expensive that millions of Americans can't afford it.
In what is believed to be the first study of its kind, researchers at the University of Washington focused on the cost of eating foods that are rich in nutrients, and low in calories, like fresh vegetables, whole grains, fish and lean meats. That's the stuff we're told we have to eat if we are going to shed a few pounds and remain healthy.
But when the researchers checked prices at numerous stores around the Seattle area, they found that the good, healthy foods had soared in price over a two-year period, jumping by nearly 20 percent compared to a 5 percent increase in the overall food price inflation. And during that same period, high-calorie foods had remained about the same price, and in some cases had actually dropped.
"We were shocked," Adam Drewnowsky, director of the Center for Public Health Nutrition at the University of Washington, said in an interview. Drewnowsky and fellow researcher Pablo Monsivais published their findings in the December issue of the Journal of the American Dietetic Association.
"The nutrient-rich calories, the food we should be eating, are zooming out of sight," Drewnowsky said. "So eating well is really becoming unaffordable for many, even in the middle class."
Even some of the most popular diets are beyond the economic reach of many.
"I don't think people were told when the Atkins or the South Beach diets came out that those diets would really cost them double or triple the amount they were spending on food," he said.
If you can afford either of those diets, he added, you're probably not obese.
Some who understand the importance of weight control would probably like to eat right, but eat cheaper foods instead.
"Sometimes it's the only decision they can make when the rent is due," Drewnowsky said.
The finger of blame has been pointed at many culprits, ranging from agricultural policies and farm subsidies to the rising cost of labor and energy, but Drewnowsky believes one huge factor is quite elemental.
"When it comes to empty calories, it's very difficult to compete with sugar," he said.
In Brazil, for example, sugar "is produced [from sugar cane] at the cost of 30,000 calories for one dollar. Nothing else comes close."
The high cost of eating right is not reflected in the annual report from the U.S. Department of Labor. The government tracks the cost of what it considers to be the typical "food basket," which includes a lot of things with added sugar and added fat and fewer nutrients.
To find out the true cost of eating right, Drewnowsky and Monsivais concentrated on two types of food — those with high calories per gram, like grains and sugars, and those with low calories per gram but high in nutrients, like fish and fresh vegetables.
