"Something very serious" is happening "at the bottom of our society" as more and more people use food banks, the Government's poverty tsar told Daybreak.
Frank Field said he had approached the Archbishop of Canterbury to lead an inquiry into the explosion of demand for food banks.
He also expressed shock at how many people needed them to get by.
"If you said to me 30-years-ago that I would be coming on television to talk about this I would have advised you to go into a dark room and actually lie down," he said.
Field admitted the causes behind food poverty were complex, but hit out at the "huge number of landlords" who do not provide kitchens, leaving tenants with only a microwave and pushing them into "expensive diets".
