Steiger said in his letter that the WHO report did not adequately address an individual's responsibility to balance one's diet with one's physical activities, and objected to singling out specific types of foods, such as those high in fat and sugar.

"The (U.S. government) favors dietary guidance that focuses on the total diet, promotes the view that all foods can be part of a healthy and balanced diet, and supports personal responsibility to choose a diet conducive to individual energy balance, weight control and health," wrote Steiger, special assistant for international affairs at Health and Human Services.

When I was stationed in Germany, I saw that Europeans as a whole seemed to have a far higher smoking rate than Americans. Perhaps they think that because they have socialized medical care, there's less need for them to take care of their own health. Why make your own decisions when the bureaucrats can think for you? Why bother to take care of the elderly during a heat wave when taking a long vacation is much more fun.
