The Office for National Statistics figures, released on Wednesday, show the cost of food and non-alcoholic drinks dropped by 0.2% between August and September.
It is the first time the cost of food and non-alcoholic drinks has fallen since May 2024.
However the figures also show the inflation rate for food and non-alcoholic drinks was 4.5% for the year to September.
For the previous six months prices consistently increased, but much of the pressure comes from the longer term.
In the five years to July, food prices increased by around 37%. Put simply, £10 worth of food bought five years ago would now cost you £13.70.
As prices of everyday staples rise, ordinary households are struggling to cope.
