Food is at the heart of every home. It accounts for 11% of a typical household's expenditure.
And since Britain's Brexit vote, we have been told to brace for price rises.
For the next 12 months, ITV News will be monitoring prices for a typical basket of 22 grocery items.
The ITV Shopping Basket includes everyday basics such as cornflakes, fish fingers and bread. Here on the ITV News website, we will be keeping it regularly updated.
At the moment, the total cost is £45.45.
Around 40% of an average household's shopping is made up of imported food.
We'll be tracking how items like coffee and chocolate are hit by the pound's lower buying power when bringing produce into the country from abroad.
Many other foods from UK producers such as cheese and milk will be vulnerable to rises in energy and fuel prices.
Official predictions on the cost of living indicate that the rate of price rises will almost triple.
The Bank of England says inflation is likely to rise from 1% to almost 3% in 2017.
Families are now expecting to see what all these months of politics and predictions actually means to them and their spending.
As price pressures tighten, households will be on the look out for cost increases...and so will we, here at ITV News.
