Massachusetts food banks are asking for more funding from the state, as the demand for help has dramatically increased. According to a spokeswoman for the Greater Boston Food Bank, the Massachusetts Emergency Food Assistance program has requested $15 million from the Patrick administration on behalf of Massachusetts food banks, a $3.5 million bump from last year. In 2006, 30,000 people called the United Way for help, and such requests are on track to triple to 90,000 by the end of this year, said Brian Adams of the United Way.
