ANN ARBOR, Mich. -- New research from the University of Michigan suggests obesity can be seen as one of the unintended side effects of free market policies.
A study of 26 wealthy nations shows that countries with a higher density of fast food restaurants per capita had much higher obesity rates compared to countries with a lower density of fast food restaurants per capita.
"It's not by chance that countries with the highest obesity rates and fast food restaurants are those in the forefront of market liberalization, such as the United States, the United Kingdom, Australia, New Zealand and Canada, versus countries like Japan and Norway, with more regulated and restrictive trade policies," said Roberto De Vogli, associate professor in the U-M School of Public Health, and lead researcher of the study.
For example, in the United States, researchers reported 7.52 fast food restaurants per 100,000 people, and in Canada they reported 7.43 fast food restaurants per 100,000 people. The paper reported the obesity rates among US men and women were 31.3 percent and 33.2 percent, respectively. The obesity rates for Canadian men and women were 23.2 percent and 22.9 percent, respectively.
Compare that to Japan, with 0.13 fast food restaurants per 100,000 people, and Norway, with 0.19 restaurants per capita. Obesity rates for men and women in Japan were 2.9 percent and 3.3 percent, respectively. In Norway, obesity rates for men and women were 6.4 percent and 5.9 percent, respectively. The relationships remain consistent even when researchers controlled for variables such as income, income inequality, urban areas, motor vehicles and internet use per capita.
Obesity research largely overlooks the global market forces behind the epidemic, De Vogli said.
"In my opinion the public debate is too much focused on individual genetics and other individual factors, and overlooks the global forces in society that are shaping behavio
