The line graph compares the amount of three types of fast food—hamburgers, fish and chips, and pizza—consumed in Britain between 1970 and 1990.
Overall, while the consumption of hamburgers and fish and chips rose substantially over the period, pizza saw a general decline. By 1990, fish and chips had become the most popular choice, overtaking both competitors.
In 1970, pizza was the leading fast food, with consumption of 300 grams, whereas fish and chips stood at slightly below 100 grams, and hamburgers were the least favoured at around 40 grams. Over the next decade, pizza consumption fell steadily to about 220 grams, and by 1985 it had been overtaken by fish and chips. It then experienced only a marginal recovery to roughly 220 grams in 1990.
Fish and chips consumption, in contrast, grew gradually from under 100 grams in 1970 to about 150 grams in 1980, before accelerating sharply, reaching approximately 500 grams by 1990. A similar upward trajectory was observed for hamburgers, which increased from about 40 grams in 1970 to just under 100 grams in 1980, and then surged to 300 grams by the end of the period.
