TUC general secretary Frances O'Grady described the numbers of people turning to foodbanks in the UK as "shocking".
The Chancellor is talking up a recovery - but for who? These new figures show that, despite trying desperately hard to make ends meet, hundreds of thousands of people still can't afford to put food on the table for their families.
Welfare reforms like the Bedroom Tax have pushed more households into food poverty.
David Cameron has come under pressure to launch an inquiry into why people are turning to foodbanks as demand for the services continue to surge.
More than 350,000 people received a three-day food package from the Trussell Trust between April and September, three times as many as the same period last year.
It has written to the Prime Minister calling on him to look into the "scandalous" problem of food poverty, warning some foodbank recipients are so poor they have returned produce that needs cooking because they cannot afford the electricity to heat it up.
Trussell Trust executive chairman Chris Mould said: "We said in April that the increasing numbers of people turning to foodbanks should be a wake-up call to the nation, but there has been no policy response and the situation is getting worse. The level of food poverty in the UK is not acceptable.
"It's scandalous and it is causing deep distress to thousands of people. The time has come for an official and in-depth inquiry into the causes of food poverty and the consequent rise in the usage of foodbanks."
Oxfam's Director of UK Poverty, Chris Johnes, has warned that welfare reforms could tip even more people into food poverty:
These shocking figures show that a perfect storm of spiralling living costs, lack of decent, secure jobs and benefit changes are making it impossible for many people to feed themselves or their families.
It's clear there is a massive hole in the safety net when so many more people are being forced to rely on emergency food handouts.
We are worried this could be just the tip of the iceberg as changes to the welfare system already in the pipeline could rip apart the safety net with devastating consequences for those who rely on it.
People who arrive for help at foodbanks are referred by doctors, social workers, schools liaison officers or advisers at the CAB and Jobcentre Plus.
Chris Mould, the Trussell Trust 's Executive Chairman, said: "We cannot ignore the hunger on our doorstep. Politicians across the political spectrum need to recognise the real extent of UK food poverty and create fresh policies that better address its underlying causes.
"This is more important than ever as the impact of the biggest reforms to the welfare state since it began start to take effect."
The government has said that it already provides a "safety net" to benefit claimants who need help with food, adding that some of the increase seen by the Trussell Trust could be due to Job Centres referring people to their service:
The government already provides a safety net for essentials like food and housing through the benefits system and claimants can also request a benefit advance or help from their local authority where needed.
We welcome the contribution voluntary organisations including the Trussell Trust play in supporting local communities, beyond the help provided by Government. That is why Jobcentre Plus - for the first time - is now referring people to their services.
Our welfare reforms will improve the lives of some of the poorest families in our communities, with the Universal Credit simplifying the complex myriad of benefits and making three million people better off.
And by next year, we will have taken two million of the lowest earners out of paying tax altogether.
The Trussell Trust says the number of people turning to them for help was a "wake-up call to the nation". The charity claims the impact of welfare reforms that came into force this month has already sparked an increase in numbers passing through their doors.
Of those helped over the last year 126,889 were children and most recipients were working-age families
30% of people helped were referred as a result of benefit delays
15% because of benefit changes
Overall, the charity helped nearly 100,000 more people than it had anticipated
