The provided line graph illustrates the key changes in the amount of three various spreads (margarine, butter and lowfat) consumed between 1981 and 2007.
Overall, it can be seen that all options followed a universal falling trend at the end of the period in question. The consumption of margarine and butter, once the most popular products, experienced a sharp decline, while the number of reduced spreads showed a significant rise, surpassing the rest of the commodities.
Looking at the details, the quantity of butter demonstrated a gentle increase from just above 140 grams to just below 160 grams, hitting its peak in 1986. Even though butter’s figure fell gradually to 100 grams, it managed to maintain its popularity until 1991. During the final years butter’s consumption volume showed a continious decrease, culminating at the level of around 50 grams.
Menawhile, the amount of margarine experienced changes, which were contrast to the butter’s at their standing points. Firstly, margarine’s volume declined slightly from approximately 90 grams to 80 in 1986, then rose to 100 grams within the next 5 years. Before falling down to the level of mere 40 grams during the final years of the period, its figure remained steady at the volume of 100 grams from 1991 to 1996.
The consumption of low fat started in 1996 with almost 10 grams, before it intensively gained its popularity up to around 85 grams until 2001. The figure of reduced spreads demonstrated a similar pattern of decrease as other products did, culminating at the volume of almost 70 grams.
