The given line graph illustrates the changes in the consumption of fish and types of meat in a European nation over 25 years, from 1979 to 2004. Units are measured in grams consumed per person per week.
Overall, it can clearly be seen that the consumption of all meat and fish declined throughout the given period, with the exception of chicken. Furthermore, although the consumption of beef was the highest at the beginning, it had been surpassed by chicken by the end of the period.
In terms of the meat with the highest consumption at the start, the consumption of beef began at around 230 grams in 1979. The consumption then dropped slightly by almost 50 grams in 1981 before rising and peaking at around 240 grams in 1983. The number then experienced a steep decline to just above 100 grams in the final year. In contrast, the consumption of chicken started at a lower level than that of beef, at around 147 grams in 1979. The number then rose moderately to around 170 grams in 1981 before dropping slightly to exactly 150 grams in 1982. It then experienced a gradual climb and reached a peak of exactly 250 grams in the final year, thus surpassing beef.
Regarding the other two less-consumed types of meat and fish, the consumption of lamb stood at a similar level to that of chicken in 1979. The consumption then experienced a gradual fall from 1979 to 2004 and hit a trough at just above 50 grams in the final year. Similarly, the consumption of fish commenced at almost 65 grams in 1979. The consumption then saw a steady growth until the final year.
