, the main "headline" measure of inflation, is currently 7.9% . But inflation for food and non-alcoholic drinks is 17.3% . A food shop that would have been £75 last year now costs Zoe £88. A full-time carer for her husband, she is grateful for the vouchers but says they will cover her food shop for only the first three weeks of the seven-week holiday. "The vouchers only stretch so far, so I'm up every night with worry," she says. "Last year, things had started to go up - but it wasn't as bad as now." The vouchers can be spent only at supermarkets, so this is where Zoe, whose surname BBC News has chosen to withhold, does most of her food shopping - switching between shops to make the most of reductions and deals. She can just about afford to feed her children the same food as last year - but she and her husband now often eat soup made from vegetables she picks up at the local food bank. "Please don't ever be embarrassed to go to a food bank," Zoe says. "We're all in the same boat - I never thought I'd go... [but] without them, we'd be in a lot worse situation."

Rising food costs have driven down the value of summer-holiday support for pupils on free school meals.
During the holidays, many councils in England offer vouchers or cash payments to help those eligible.
But BBC News research shows 67 of 92 councils have cut or kept their support the same as last year, leading to a drop in value once food inflation, currently 17.3%, is taken into account.
Support has ended in Northern Ireland and varies across Wales and Scotland.
Zoe, from Harlow, Essex, has three children, eight, 10 and 18, all entitled to free school meals during term time and vouchers worth £75 each for the summer holidays.
