Families are facing more potential debt problems as the average UK family is set to spend an extra £1,000 on food shopping a year, according to new research. The cost of food has risen across the top supermarkets, meaning that families are having to tighten their belts during the credit crunch in order to stop themselves falling into further debt.

Mysupermarket.co.uk have revealed that the average trolley price has risen by 21% in the past 12 months alone. They researched 24 staple items such as fruit, bread and pasta. Dairy and wheat products have seen the biggest price increase, with six pints of semi-skimmed milk rising from £1.68 to £2.12.

Johnny Stern, director of the site, says: “We would advise shoppers trying to stick to a tight budget to look out for better-priced like-for-like items and special offers within the supermarket you already shop at – there are significant and regular savings to be had to combat the crunch.”
