Cheap food is a key factor in the obesity of Americans
New review experts summarizes what is known about economic factors tied to the obesity epidemic in the United States. Two PhD from the University of Illinois found a key contributing factor to obesity is the cheapest in the history of American food.
Today, two out of three Americans are overweight or obese. Many factors have been suggested as causes: snack food, automobiles, television, fast food, computer use, vending machines, and the size of the portions.
The authors say that the formation of a coherent picture is a challenging task, but you should evaluate how proposed solutions, from encouraging physical activity to reduce access to foods high in calories can change the situation.
After studying the available evidence, the authors say widespread availability of cheap food has the strongest effect on obesity.
They write: "Americans spend a smaller share of their income (or corresponding amount of work) on food than any other member of society in history or elsewhere in the world, but gets her more." In the 1930s, Americans spent one quarter of their income on food. By 1950, this figure had fallen to one-fifth. The latest data show that the proportion of income spent on food is now within one tenth.
The authors consider the influence of other factors: electronic entertainment, more frequent use of cars and increased urbanization, which also contribute to obesity. But they say that their impact is much less.
The authors also suggest that policy measures aimed at, for example, to increase the consumption of fruits and vegetables and increased physical activity may not be the best approach.
They came to the conclusion that the more promising is the focus on reducing consumption of calories, especially sweetened beverages and salty snacks. They write: "Although increasing fruit and vegetable consumption may be a laudable goal for other health reasons, it is unlikely to be an effective tool for the prevention of obesity."
