The majority of potatoes in the United States are now used to make processed forms such as frozen potato products, mashed potatoes, and canned potatoes. The share of potatoes used for frozen foods, particularly french fries, has been increasing since 1979, with nearly half of all processed potatoes now going towards frozen products. However, there was a slight decline in the availability of frozen potato products in the late 1990s and early 2000s due to low-carb diets and alternative food choices, but it has since risen again.
