The British diet has undergone a transformation in the last half-century. Traditional staples such as eggs, potatoes and butter have gradually given way to more exotic or convenient foods such as aubergines, olive oil and stir-fry packs.

Explore the changes across four decades and hundreds of food and drink categories in this interactive visualisation, featuring data from the Department for Environment, Food and Rural Affairs (Defra). Defra has just released almost 30 years of food diaries filled out by British families between the 1970s and 2000 as open data. This is part of #OpenDefra, and 2016: Year of Great British Food.

You can find out more about the history of the data and how some food categories have been described here.

All foodstuffs are measured in grams and all liquids in milliliters.
