The provided line graph illustrates the weekly consumption of three fast food items—Hamburgers, Fish & Chips, and Pizza—in the United Kingdom over two decades from 1970 to 1990.
Overall, it is evident that Hamburger consumption exhibited a prominent upward trend, while Fish & Chips displayed fluctuations with a significant decline towards the end of the period. In contrast, Pizza consumption demonstrated a steady increase throughout the years.
In 1970, Hamburger consumption started at 100 grams per week, showing consistent growth by increasing to 200 grams in 1975. This trajectory continued as it reached 300 grams in 1980, followed by a notable rise to approximately 405 grams in 1985. By 1990, Hamburger consumption peaked at 500 grams per week, establishing it as the most popular fast food item throughout this period. Conversely, the consumption of Fish & Chips exhibited a different pattern. Beginning at approximately 305 grams in 1970, it saw a slight decline to 300 grams in 1975. After stabilizing at this level for a few years, it experienced another drop to 200 grams by 1990, which indicates a significant decline in popularity.
Pizza consumption commenced at zero grams in 1970 and remained unchanged until 1975. However, starting in 1980, it began to gain traction, reaching 100 grams per week. This upward trend continued as it rose to approximately 185 grams in 1985 and culminated in 300 grams by 1990. This consistent increase highlights the growing acceptance and popularity of Pizza as a fast food choice among the UK population during the observed years.
