Rising food costs are a concern for nine out of 10 people in Northern Ireland, the Consumer Council has claimed.
The watchdog said 82% of people have changed the way they shop, cook and eat because of spiralling prices.
A further 34% have spent less, 29% have avoided impulse buys and 28% planned meals more carefully to avoid waste.
Consumer Council chief executive Antoinette McKeown said: "Our research has found that almost 87% of people are worried about the cost of their food and groceries and it's a concern that cuts across all ages, income brackets, cities, towns and villages."
In a report published on Tuesday, the Consumer Council highlighted how some families are struggling to maintain a healthy lifestyle.
Ms McKeown added: "The report reflects the anxiety felt by consumers trying to afford a healthily balanced diet. We heard from parents and those with medical or dietary requirements in particular.
"We will use our report to work with Government and food industry representatives to ensure that the consumer voice is heard and to address the issues raised by consumers."
Almost two-thirds (61%) of people felt supermarkets could do more to help, by charging a fair price and simplifying promotions.
"By addressing some of these issues we hope to help consumers shop confidently and healthily and for less," said Ms McKeown.
