The Pine Ridge Reservation in South Dakota is home to about 30,000 people; most are Oglala Lakota.
With 80 percent unemployment, the majority of residents live well below what is commonly known as the "poverty line."
The South Dakota County where Pine Ridge is located consistently ranks as the poorest per capita in the US.
Many rely on USDA surplus commodities that are typically high in fat, salt and sugar and exacerbate the high incidence of diabetes, high blood pressure and heart disease there.
