The provided line graph depicts the changes in the amount of three different types of fast food consumed weekly by individuals in the United Kingdom over a 30-year period, spanning from 1990 to 2020.
Overall, it is clear that while the consumption of fish and chips experienced a significant decline over the three decades, the popularity of both hamburgers and pizza showed an upward trajectory. Furthermore, hamburgers emerged as the most widely consumed fast food among the three by the end of the period.
In 1990, fish and chips was the undisputed favorite, with weekly consumption standing at precisely 300 grams per person. However, this figure saw a steady and continuous drop over the following years, plummeting to roughly 220 grams by 2000 and eventually reaching its lowest point of approximately 150 grams in 2020.
Conversely, the intake of hamburgers and pizza began at much lower levels. In 1990, the weekly consumption of pizza was relatively low at 50 grams, while hamburgers stood slightly lower at around 40 grams. Over the subsequent decades, the consumption of pizza saw a gradual and steady rise, ending the period at roughly 120 grams. Meanwhile, the popularity of hamburgers surged dramatically; consumption skyrocketed to match that of fish and chips by 2000 and continued to climb steeply, ultimately peaking at an impressive 300 grams per person per week in 2020.
