The line graph illustrates how frequently people consumed hamburgers, fish and chips, and pizza from 1970 to 1990.
Overall, it is clear that hamburgers and fish and chips increased significantly over the two decades, whereas pizza showed a steady decline. Although it started as the highest, pizza fell continuously and became the lowest by the end of the period.
In 1970, pizza was the most popular option. However, it underwent a substantial decrease, falling from around 300 to about 200 in 1990.
In contrast, hamburgers recorded the lowest figure in 1970, at only 20 times. The number increased steadily to 100 in 1985, although it remained less popular than the other two items at that point, before rising sharply to about 290 in 1990 and overtaking pizza. Similarly, fish and chips increased from 80 in 1970 to around 120 in 1990, making it the second most consumed item at the end of the period.
