The graph illustrates the consumption of fast foods: specifically hamburgers, fish and chips, and pizza among British people over a period of 20 years.
Overall, fish and chips were the most consumed fast food item throughout the 20 year-period in Britain. In contrast, pizza saw a decline in consumption, while the popularity of hamburgers displayed a steady increase.
In 1970, both fish and chips and hamburgers experienced a gradual rise in consumption of nearly 100 grams; this trend remained steady in 1975. During the same period, pizza began at 300 grams in 1970 and gradually decreased to below 300 grams over the next five years. By 1980, the consumption of both hamburgers and fish and chips continued to rise. However, fish and chips experienced a dramatic increase of 300 grams in 1985, while the consumption of pizza dropped from below 300 to 200 grams.
The consumption of fish and chips reached its peak in 1990, climbing to 500 grams. Hamburgers also saw a significant increase in consumption, rising to 300 grams, whereas the consumption of pizza remained stable between 1985 and 1990.
