The provided line graph illustrates the weekly consumption of fish and three types of meat in a certain European country at five-year intervals between 1979 and 2004. Overall, while different trends were observed across all foods in the list, fish was constantly consumed in lower quantities. Notably, chicken emerged as dominant food by the end of the period.
In 1979, beef consumption led the overall pack with about 225 grams. Despite an initial sharp fall to around 175 grams, the figure then recovered, reaching a high of approximately 240 grams in 1984. Thereafter, the figure exhibited an almost continually downward trend and finished the period at nearly half of its initial level, at roughly 110 grams in 2004. Meanwhile, lamb consumption also mirrored the same pattern. Starting the period at exactly 150 grams in 1979, the figure then decreased close to 60 grams by the end of the period.
In contrast, chicken climbed from less than 150 grams in 1979 and took the lead from 1990 onwards. Initially, chicken consumption showed a steady increase and exceeded beef consumption in 1990. Experiencing a significant increase, the figure reached a whopping around 250 grams before decreasing again in 2004.
Fish, in comparison, was always eaten in less quantities. Beginning the period at roughly 60 grams in 1979, the figure then dropped to below 50 grams. Interestingly, fish consumption remained relatively stable at this level for the majority of the period.
