Coffee pods and cream liqueur are rising in popularity but nightclub entry fees are on the decline, according to the Office of National Statistics.
The ONS calculates consumer price inflation (CPI) - often used to assess changes to the cost of living - using the average prices of a "basket of goods".
The basket is updated each year with different items to reflect changing shopping trends.
Night club entry fees, CD-ROMs and re-writable DVDs have been removed from the basket in 2016.
Coffee pods, cream liqueur, leggings, large chocolate bars, meat-based snacks and lemons have been added to the basket this year.
ONS collects around 110,000 individual prices each month from 20,000 shops across the UK, as well as a further 70,000 prices online.
The 'weight' of each item – its relative importance in calculating CPI – is based on survey evidence of people's spending gathered by ONS from its own sources and commercial market research.
