The line graph compared to the consumption of Pizza, Fish and chips, Hamburgers with Australian teenagers between 1975 and 2000.
It is clear that the consumption of fish and chips noticeably declined, whereas the amount of Hamburgers and Pizza that were eaten increased over the period shown.
In 1975, the number of times Australian teenagers ate fish and chips was highest, being eaten 100 times a year. While the figures for Hamburgers and Pizza were lower, approximately 10 times and 5 times respectively a year. However, apart from a brief rise again from 1980 to 1985, the consumption of fish and chips gradually declined over 25 year timescale to finish at just under 40 times per year.
In sharp contrast to this, teenagers ate the others two fast foods at much higher levels. Pizza consumption increased gradually until it overtook that of fish and chips in 1990. It then leveled off from 1995 to 2000. The consumption of hamburgers was highest, increasing sharply from 1970’s to 1980’s. The number of times teenagers consumed hamburgers exceed that of fish and chips in 1985. It finished at the same level that fish and chips began, with consumption at 100 times per year.
