Move over, pork pies and leg waxing; raspberries and gym attire are now considered in vogue for British consumers, whose eating habits are changing as they become more health conscious.

The “shopping basket” of goods which is used to measure the rate at which prices are increasing in the UK has changed, according to the Office for National Statistics. Consumer consumption tastes shift over time. As a result the ONS updates its “shopping basket” ingredients each March in order to measure the aggregate impact of rising prices more accurately.

While the choice of goods and services often seems humorous, accurately measuring consumer prices is vital part of determining the pace of inflation. This in turn informs the decision making process of the UK’s central bank, the Bank of England, when it examines the need to raise or lower interest rates. The price a consumer pays for a pork pie may help inform whether or not the cost of servicing a mortgage increases, for instance.
