(NETWORK IN) The economy is improving but almost 16 percent of Indiana’s households are struggling to put enough food on the table, according to the Food Research and Action Center, a national anti-hunger group. The rate is nearly 19 percent for households with children. And their hardship “often goes unseen by those not looking for it”, says Emily Bryant of Feeding Indiana’s Hungry, a statewide association of food banks. Hunger, she says, can hide behind the doors of nice houses with mortgages in default, or the heat turned off, or all of the income going to housing costs, leaving little or no money for food. Or behind “the stoic faces” of parents who skip meals to protect their children from hunger.
