The line graph illustrates the total proportion of junk food intake in three distinct categories, including hamburger, fish and chips, and pizza in England between 1970 and 1990.
Overall, fish and chips and hamburger show an upward trend in the consumption of fast food, although pizza experience a considerable decrease throughout the period. Fish and chips feature the most dramatic rise and have the highest number of junk food. Units are measured in grams.
In 1970, pizza had the highest proportion of food intake at 300, followed by fish and chips at approximately 95 and hamburger at about 3. The figure of pizza dropped gradually, fluctuating between 1980 and 1985, and showed a small recovery to finish the data at 300 in 1990.
Additionally, pizza experienced a steady growth, with a notable climb after 1985, then surpassed pizza in 1990. In contrast, the proportion of fish and chips remained relatively stable until 1980, after which it rose sharply, overtaking both food and peaking at exactly 500 in the final year surveyed.
