#1 Worst Diet: Greenville, SC
Greenville has the dubious distinction of the nation's worst diet, thanks to coming in dead last for eating whole grains, and ranking #46 for eating fruits and vegetables. Residents' poor diet contributes to their high rates of hypertension. On a positive note, Greenville is adding more healthy foods to its schools' lunch menus and creating more farmers' markets. Changes like these can help locals live healthier -- even on a budget -- despite having some of the lowest incomes in the country.
