The line graph presents data on the consumption of three distinct categories of fast food – hamburgers, fish and chips, and pizza – measured in grams over a two-decade period from 1970 to 1990.
Overall, the graph reveals a significant shift in fast food consumption trends, with an increase in pizza consumption and a more modest rise for hamburgers and fish and chips.
In 1970, hamburgers were the most popular fast food item with a consumption level of approximately 300 grams, followed by fish and chips at around 100 grams. Over the decade leading up to 1980, both hamburgers and fish and chips experienced steady growth, with fish and chips reaching an estimated 150 grams. However, from 1980 to 1990, fish and chips consumption surged dramatically, peaking at just over 200 grams. During this same period, hamburger consumption rose more moderately, reaching approximately 350 grams by 1990.
Conversely, pizza exhibited the most remarkable transformation over the two decades. Starting at a modest 50 grams in 1970, pizza consumption displayed a steady upward trajectory, culminating in a significant increase to 500 grams by 1990. This marked a surpassing of both hamburgers and fish and chips in terms of consumption rates. Notably, despite its initial lower consumption levels, pizza experienced the most significant growth, highlighting a prominent shift in consumer preferences over the examined years.
