The given line graph illustrates the amount of consumption of three different kinds of spreads (margarine, butter, and low fat & reduced spreads) between the years 1981 and 2007. Units are measured in grams.
Overall, it is apparent that butter was the most popular spread at the start of the period. While margarine was the dominant spread in the middle of the given period, low fat & reduced spread became the most widely used in the last year. Furthermore, margarine and butter consumption decreased over the period, whereas low-fat & reduced spreads increased significantly.
In terms of butter, in 1981, it began at around 140 grams and then peaked at around 160 grams in 1986. After the subsequent years, a dramatic decline was seen in its consumption to reach slightly over 40 grams in the final year. In the meantime, the consumption of margarine started at nearly 90 grams in 1981, after which it fluctuated until 2001 to reach 80 grams before it experienced a noticeable drop to reach its low point of 40 grams in 2007.
On the other hand, low fat & reduced spreads started to be eaten in 1996 with only below 20 grams. After that, it rapidly grew to peak at over 80 grams in 2003 before it slightly decreased to reach nearly 70 grams in 2007.
