Shoppers are paying 17% more for low-cost everyday items in UK supermarkets, new figures show.
A report from the Office of National Statistics (ONS) reveals that in the 12 months to September, the price of vegetable oil increased by 65% and pasta by 60%, well above the overall figure for food and drink inflation.
Other notable increases on basic items included tea (46%), chips (39%), bread (38%) and biscuits (34%).
In the last five months alone, vegetable oil has gone up by 46%, chips by 24% and bread by 22%.
The increase for the lowest-cost grocery items is greater than the wider rate of inflation for food and drink of 14.5%.
Of 30 products tracked by the ONS, the only items that fell in price were orange juice (down 9%), minced beef (7%) and sugar (0.3%).
The statistics body cautioned however that this new analysis uses experimental methodology and is therefore less robust than official statistics.
Overall, UK inflation is currently at a 40-year high of 10.1%.
A significant factor behind the rise in the cost of groceries is the war in Ukraine, which has disrupted supplies of grain, vegetable oil and fertiliser from the region.
