According to research by the charity Food Foundation, as food prices rise, more and more Britons say they are running out of food every day.
According to an online survey, about one in seven adults begin to eat less, reduce the amount of meals, or simply choose to go hungry.
The main reason why people's lives are so difficult is that the cost of energy is high, and food manufacturers push the cost to consumers, which makes food more expensive.
Prices in the UK are up 7% this year, the highest level in 30 years.
The Bank of England warned that inflation could reach 10 per cent in a matter of months as rising fuel and food prices weighed on household budgets.
The Food Foundation also said that people are increasingly choosing to buy more cold food from food banks due to concerns that cooking items will increase energy costs.
Global opinion and data firm YouGov conducted an online survey of 10,674 adults between April 22 and 29. The survey found a 57% increase in the number of people who had problems buying food within three months.
Nearly 14 percent of survey respondents said they or someone in their family had eaten less or no food in the past month because they could not afford it. In January, the percentage was 8.8% of respondents.
Anna Taylor, executive director of the Food Foundation, said the situation was "rapidly shifting from an economic crisis to a health crisis" and that the food bank "may not be able to solve" the problem. "The government needs to realize that many families are sinking and need to be helped quickly. Emergency food parcels for rescue will not work. ”
A government spokesman said: "We recognise the pressure on the cost of living and we are doing everything we can to help, including spending £22bn in the next financial year to help people pay for energy and cut fuel taxes.
"For those hardest hit, we are investing an average of £1,000 more per year into working families and raising the minimum wage for full-time workers by more than £1,000 per year through universal credit, and our Family Support Fund can help cover the cost of daily necessities."
Shadow Jobs and Pensions Minister Jonathan Ashworth said: "These are devastating findings that shed light on the severe hunger impact of the Conservative Cost of Living crisis on families and children across the country. ”
Professor Michael Mamot, director of the Institute for Health Equity at University College London, said the findings showed society "fundamentally failed".
"These figures on food insecurity are even more chilling because the problems are solvable. But, far from being resolved, it's getting worse," he added.
