The cost of supermarket food has jumped to its highest level in 13 years, according to new research, as shoppers continue to struggle against the cost of living crisis.
Grocery inflation hit 7% in the four weeks to May 15, up from 5.9% just one month ago, market researcher Kantar said.
Kantar said the products where prices are rising fastest include dog food, savoury snacks and fresh beef.
The cost of a family fry up with toast, eggs, sausages, bacon and beans has risen 40p since last year - up to £6.93.
Prices are going up off the back of increased costs for food producers, including energy and fuel.
The war in Ukraine is also pushing up costs, with Russia being one of the key suppliers of wheat and fertiliser.
In a warning over how rising costs are affecting families, Kantar said over one fifth of British households now describe themselves as "struggling" to make ends meet.
Within the 22% of shoppers struggling financially, the rising price of groceries was a worry to over nine in ten people.
The latest grocery insights come as overall UK inflation rose to a 40-year high of 9% last month.

Fraser McKevitt, head of retail and consumer insight at Kantar, said: "People are really feeling the squeeze at the supermarket tills and they're having to stretch their budgets further to accommodate rising prices.
"To put the most recent numbers into context, if you were picking up supplies for a family fry-up over the long weekend with toast, eggs, sausages, bacon, and beans it would cost you £6.83 - that's a significant 40p increase on last year."
Kantar said supermarket sales fell 4.4% over the 12 weeks to May 15 year-on-year and were down 1.7% over the last month.
Aldi and Lidl were the fastest growing supermarkets over the 12 weeks, with sales up 5.8% and 6.0% respectively, as shoppers switch to the budget chains to save money.
Kantar said Aldi and Lidl now have a record combined market share of 15.9% of the supermarket sector.
Tesco, the biggest grocer in the UK, increased its market share by 0.4 percentage points to 27.4%.
Kantar expects the Queen's Platinum Jubilee celebrations to boost food sales, with alcohol, soft drinks, barbeque foods, and desserts expected to be particularly popular over the bank holiday weekend.
The Queen's Platinum Jubilee celebrations will take place between June 2 and June 5.
Kantar noted that the Diamond Jubilee in 2012 saw a 10% boost in supermarket sales during the week leading up to the festivities.
