Despite the fact that our nation's potato consumption is at its lowest point in 30 years — down 20% since 1996, in fact — our kids are consuming so much of the vegetable in school lunches that it's become a topic of debate in the Senate. The government would like to see potatoes in school lunches limited to only two servings per week, but senators from big potato-growing states are arguing against the USDA's suggestions by ranting, raving, and comparing it to the villainous iceberg lettuce. Except that potatoes are delicious.
