The diagram illustrates the consumption of different spreads (margarine, low-fat & reduced spreads, and butter) between 1981 and 2007. The units are measured in grams.
Overall, what stands out from the graph is that although the highest proportion of margarine was consumed at the beginning of the period, by 2007, the other spreads had overtaken that of low-fat & reduced spreads. Except for reduced spreads, the others experienced a fall throughout the period.
Looking at the details, the indicator for butter ranked first, accounting for nearly 140 grams in 1981. Over the next 10 years, a dramatic decrease was observed in this rate, reaching 100 grams. Approximately 90 grams of margarine was used by people in 1981, and from 1986 to 1991, it increased gradually to 100 grams. In 1991, the rate of butter was outstripped by the figure for margarine, and during the next 5-year period, the former saw a sharp fall to roughly 70 grams, whereas the latter remained stable at 100 grams. In 2007, the indicators of butter and margarine comprised approximately 50 and 40, respectively.
With regard to low-fat & reduced spreads, it started to be consumed in 1996 and stood at about 10 grams. After a significant rise to nearly 83 grams, the share of this spread dropped gradually to around 72 grams.
