The cost of milk, cheese and eggs has risen at the fastest rate in 45 years, helping drive overall inflation to its highest level in four decades.
Earlier today it was announced there has been a higher-than-expected leap in the rate of inflation, taking it to 11.1% last month.
Increases across a range of items - including gas, electricity, food and drink - are some of the biggest drivers of inflation, while a decrease in motor fuels partially offsets the rise.
Inflation on food and non-alcoholic beverages is now estimated to be at its highest rate since prices in this area rose by 16.4% in 12 months - the highest since September 1977 when it stood at 17.6%.
Families have been hit by soaring costs of staple foods, such as milk, cheese and eggs, while there were also significant hikes across everyday items, including sugar, tomato ketchup and jam.
Collectively, the price of shop-bought milk, cheddar cheese and eggs has risen by an eye-watering 27.3% in the previous 12 months.
Within this, low-fat milk has risen by 47.9%, eggs by 42.1%, and cheese and curd by 27.1%.
The price of butter and margarine is also up by 29.7% and 42.1% respectively.
The cost of cooking oils and fats now 33% higher than they were a year ago. Most of the UK's sunflower oil comes from Ukraine and - following Russia's invasion of the country - there were supply shortages earlier this year.
The rise in the cost of groceries has been accelerated by the war, which has pushed up the cost of fertiliser and animal feed due to the impact on grain supply from the region.
Global meat and dairy prices have jumped as a result.
Of the non-alcoholic drinks, mineral water, soft drinks and juices have risen the most, with prices now 14.6% higher.
The rise in inflation was partially offset by motor fuels after average petrol prices fell on the month.
However, the price for diesel rose - taking the disparity in price between the two fuels to its highest on record.
"There was further evidence that costs facing businesses are rising more slowly, driven by crude oil and petroleum prices," said Grant Fitzner, chief economist at the Office for National Statistics (ONS).
