provided chart illustrates the weekly consumption of fish and various types of meat per person, measured in grams, over a span from 1979 to 2004.
Overall, chicken consumption exhibited a marked increase throughout the period, while lamb and beef consumption demonstrated a decline. Notably, fish consumption remained consistently low across the years.
In 1979, beef consumption was recorded at 225 grams per person, but this figure experienced gradual fluctuations, declining to 175 grams in 1989 and returning to a peak of 200 grams in 1994 before ultimately diminishing to 175 grams by 2004. Conversely, chicken consumption commenced at a relatively modest 150 grams in 1979, but embarked on a steady upward trajectory, reaching 200 grams in 1989 and further escalating to nearly 250 grams by 1999, surpassing that benchmark slightly by 2004. This trend indicates a growing preference for chicken as a primary source of protein amongst consumers over the examined years.
Lamb consumption mirrored the downward trend observed in beef, beginning at approximately 150 grams per person in 1979 and plummeting to about 50 grams by 1994, after which it stabilized at that level. Additionally, fish consumption remained notably low, consistently averaging around 50 grams per person throughout the entire timeframe without significant variation. This indicates that, despite the fluctuations in meat consumption, fish has persistently been the least favored protein source among consumers over the years
