The line graph illustrates the changes in the consumption of three types of fast food—hamburgers, fish and chips, and pizza—in the United Kingdom over a twenty-year period from 1970 to 1990.
Overall, the intake of fish and chips and hamburgers showed significant growth throughout the period, whereas pizza consumption declined and then remained steady. Among the three, fish and chips emerged as the most widely consumed fast food item by the end of the timeframe.
In 1970, pizza was the most popular, with approximately 300 grams consumed per person weekly. However, its consumption steadily decreased over time, settling at around 220 grams by 1990. On the other hand, hamburgers, which began at a low point of roughly 20 grams, saw a continuous and sharp increase, reaching nearly 300 grams per person by the end of the period.
Fish and chips started at about 80 grams in 1970 and rose steadily to nearly 200 grams by 1980. In the following decade, their popularity surged dramatically, peaking at 500 grams in 1990, making them the most consumed fast food in the UK during that year.
