The line graph illustrates the consumption patterns of three types of fast food in Britain from 1970 to 1990.
The graph reveals a notable shift in the popularity of these fast foods over the two decades, with pizza, hamburgers, and fish and chips exhibiting distinct trends.
Initially, in 1970, hamburgers were the most consumed fast food, with approximately 300 grams per capita, followed by fish and chips at 100 grams, and pizza at 50 grams. However, by 1990, pizza consumption had surged to 500 grams, surpassing hamburgers at around 350 grams and fish and chips at just over 200 grams.
A closer examination of the graph reveals that pizza consumption fluctuated over the period, while hamburgers and fish and chips experienced steady growth. Interestingly, fish and chips overtook pizza in popularity after 1980, and by 1990, it had become the second most consumed fast food, with hamburgers emerging as the third most popular option.
