America is considering changing the classification of potatoes from vegetables to grains. Americans consume 22 kilograms of potatoes annually on average, about half of which are in the form of frozen products such as French fries.

Supporters of changing potatoes from a vegetable to a grain consider this a public health problem, as more than 40% of American adults suffer from obesity. This controversy is reminiscent of the attempt of the administration of President Ronald Reagan to classify ketchup as a type of vegetable. However, this project was quickly withdrawn after it was widely rejected.
