Shoppers are paying 10% more for food than last year, but some grocery prices have actually doubled.
Inflation has hit a 40-year high, and how much it costs just to buy essentials is rising at a near-record rate, according to the Office for National Statistics (ONS).
Overall, food prices have gone up by 9.8%.
But some common items have risen in price by even more than that.
More than 120 of the most popular foods have risen by at least 40% in a year, the Mail on Sunday reports.
Petits Filous dairy drinks and own-supermarket salt have gone up by 100%, for example.
Cooking oil made by Crisp ’N Dry has risen 80% in price, according to analysis of the four largest supermarkets by Assosia.
Meanwhile a 200g can of Heinz baked beans and sausages has gone up 73%, from 70p to £1.21.
Shoppers may associate own-brand products with being good value.
But these items have gone up in price the most.
Own-brand pasta has risen by more than 40% in cost in many supermarkets.
Standard 500g pasta packs have gone up by 57%, from around 30p to 83p.
Big pasta brands like Napolina have seen similar price hikes.
When inflation rises, it means that your money doesn’t go as far as it used to.
For example, if something cost £1 a year ago and the rate of inflation is 9.4%, it would cost £1.094 today.
Supplies of olive oil, sunflower oil and rapeseed oil have been affected by the ongoing conflict between Russia and Ukraine - both of which are key suppliers of these oils.
Many supermarkets have been rationing how much cooking oil Brits can buy.
What it means for your weekly supermarket shop
The price of other food is also soaring. Overall, food prices have gone up by 9.8%.
Within this, the ONS said the cost of milk, cheese and eggs had gone up 14.8%.
Meat prices are up by 11.1% and coffee, tea and cocoa by 10.3%.
Bread was up 9.6%, and fish 8%.
The price of fruit is up 6.9%, and vegetables by 9%.
Sugar, jam and chocolate prices have risen by 3.9%.
Meanwhile there has been an 8.8% increase in the price of fruit juice, soft drinks and mineral water.
McDonald’s is also hiking prices by up to 20p across many of its menu items - with the burger chain blaming rising inflation.
The fast food chain only gave one exact example - its humble cheeseburger, which has gone up in price from 99p to £1.19.
McDonald's has not raised its cheeseburger prices for 14 years.
Exactly how much McDonald's food will go up in price by will vary a bit - but the restaurant giant says some items will increase by between 10p and 20p.
Each McDonald's branch is free to set its own prices - except on the saver menu, where different franchises tend to charge the same amount.
