The line graph illustrates the amount of fish, chicken, beef, and lamb eaten per person per week in a European country over a 25-year period, commencing from 1979.
Overall, while the quantity of chicken intake exhibited an upward trend over the years shown, a reverse pattern could be seen in the figures for the remaining categories. In addition, chicken had surpassed beef to become the most common source of protein consumed by the end of the surveyed period.
In 1979, the amount of beef consumed per person per week was the highest among the four categories, with approximately 220 grams. In the same year, lamb was averagely consumed 150 grams each week, followed by the consumption of chicken, which was slightly lower than that of lamb. The demand for fish as food was the lowest one.
After fluctuating significantly, beef consumption witnessed a plummet of around two times, hitting the lowest point of its own, around 110 grams, from 1984 to 2004. Similarly, there was also a consistent decrease to under 100 grams in the value of lamb while that of chicken increased significantly to peak at about 250 grams, reaching the highest point in the given period. Unlike the other three kinds of meat, the level of fish consumption remained relatively stable, with around 50 grams during the whole period.
