The line chart compares weekly consumption of four different types of food, in grams, in a specific nation in Europe from 1979 to 2004.
Overall, it is evident that the importance of beef and lamb in the average diet gradually diminished, while chicken had an increasing influence throughout. In contrast, fish remained the least favourable meat over the surveyed time frame.
Beef and lamb both exhibited a downward trend in ingestion rate during the period, despite being the most and second consumed kinds of meat at the beginning. Approximately 220 grams of beef was ingested in 1979, prior to a peak at around 240 grams in about 1982, and dramatically reduced to about 100 grams in 2004. Similarly, the figure for lamb showcased a significant decrease, albeit at a different rate. The amount of lamb consumed commenced at 150 grams in 1979, and concluded the period at around 55 grams.
Concerning the remaining categories, the quantity of chicken ingested experienced an upswing over the examined period. Starting at nearly 150 grams, it surpassed lamb in around 1980 to become the second most consumed meat, before overtaking beef as the most ingested meat in about 1989, ending the period at nearly 250 grams. By contrast, the amount of fish consumed remained relatively stable throughout, hovering at around 50 grams.
