The line chart illustrates changes in the consumption of three types of fast food in the UK between 1970 and 1990.
Overall, both hamburgers and fish and chips became more popular over the period, while the reverse was the case for pizza. It is also notable that fish and chips overtook pizza to become the most consumed option, while hamburgers remained the least popular choice for all surveyed years, except for the final one when it became the second most consumed fast food.
Looking first at pizza, it was the only category that showed an overall downward trend. In 1970, it was the most popular fast-food choice, being consumed over 300 grammes. However, consumption then fell continuously to 200 grammes in 1985, before recovering slightly to around 210 grammes by 1990. This change made pizza the least consumed option in the final year.
Moving onto fast foods that experienced an increase in their consumption, hamburgers were initially the least popular choice, with a consumption of about 30 grammes in 1970. However, hamburger intake then rose steadily, tripling to roughly 100 grammes in 1985, and then it surged to just under 300 by 1990, surpassing the figure for pizza. By comparison, the UK citizens consumed more fish and chips throughout the timeframe. In 1970, about 90 grammes of fish and chips was consumed, after which the figure grew to around 150 gramms in 1980. This was followed by a threefold increase to 500 grammes by 1990, making fish and chips by far the leading fast food in terms of consumption in the end of the period.
