The lawmakers — which include members of the ruling Conservatives and opposition parties — said the government had allowed hunger to “fall between the cracks.”
“Instead of seeing hunger as an issue abroad, the government’s New Year resolution should be one of taking urgent action at home to tackle hunger and malnutrition,” said Mary Creagh, an opposition lawmaker who chairs the Environmental Audit Committee.
A combination of high living costs, stagnating wages and the rollout of a new welfare benefits system was causing people to live with hunger, she added.
The committee's report also said the issue is leading to both malnutrition and obesity as people are forced to rely on cheap, calorie-rich foods.
The recommendation follows a damning report on the rising levels of poverty in Britain published last year by the United Nations. It found that almost one-in-three children in the U.K. are growing up in poverty.
Brexit means the U.K. will also lose billions in E.U. funding, which has greatly benefited the country's most deprived areas.
The committee's report recommends that a "minister for hunger" is appointed to analyze the scale, causes and impacts of households living with limited access to food — including malnutrition and obesity.
It also highlights that there is no national government measure for hunger, but think tanks and charities estimate that somewhere in the region of two to three million people are undernourished. The U.K.'s population is about 66 million.
