Brits are facing an extra £643 cost on the annual price of their supermarket shopping as food inflation hits record highs.
Grocery inflation shot up to 13.9% over the 12 weeks to 2 October, according to researchers at Kantar.
This is the highest it has been since the company began tracking prices during the 2008 financial crash - and it means the average UK household will spend £5,265 if they continue to purchase the same products.
Food inflation is up from 12.4% a month ago, when the added extra on your supermarket shop stood at £571 on average.
Kantar said the products that rose the most in price were milk, dog food and margarine.
Researchers also noted more people purchasing for cheaper, own label, supermarket brands - of which sales were up 8.1% - as shoppers ditch branded goods to save money in stores.
Sales of branded lines - which are generally more expensive - fell by 0.7%.
Meanwhile, sales of cooking appliances including slow cookers, air fryers and sandwich makers - which typically use less energy - rose 53% on a yearly basis in the four weeks to September.
Kantar also noted that sales of duvets and electric blankets increased 8%, while sales of candles increased 9%, suggesting people may be preparing for possible winter blackouts.
Fraser McKevitt, head of retail and consumer insight at Kantar, added: "With an eye on rising energy bills, shoppers appear to be searching for cheaper ways to cook as they try to avoid using their ovens.
"Sales of cooking appliances including slow cookers, air fryers and sandwich makers, which generally use less energy, are up by 53%.
"Meanwhile sales of duvets and electric blankets have grown by 8% while candles increased by 9%, suggesting people may be preparing for possible winter blackouts."
For the fifth month in a row discounter Lidl was the fastest-growing grocer, pushing up its sales 20.9% over the 12 weeks.
This puts it marginally ahead of rival Aldi whose sales rose 20.7%.
Consumer Price Index (CPI) inflation currently stands at a 40-year high of 9.9% - with rising food prices and energy costs largely blamed for pushing up the cost of living.
