The provided line graph compares the consumption of three types of fast food—hamburgers, fish and chips, and pizza—in Britain from 1970 to 1990. From an overall perspective, it is clear that the consumption of all types of fast food initially increased. However, pizza experienced a dramatic decline and then remained stable, while fish and chips became increasingly popular and reached its peak during this period.
Pizza was initially the most preferred option, peaking at 300 grams before dramatically dropping from 290 grams in 1980 to 210 grams. After that, its consumption remained stable without showing any increase. In contrast, fish and chips started at just over 90 grams in 1970 and rose steadily, peaking at 500 grams between 1980 and 1990.
Hamburgers were the second most popular type of fast food. They began to increase in consumption from 1970, starting at 20 grams in 1980. This type of food then saw a significant increase over the subsequent five years, rising from 100 grams to 300 grams.
