The provided line graph depicts data on the amount of different spreads eaten over a 26-year period beginning in 1981. The daily consumption per person is expressed in grams.
Overall, the intake of all spreads saw a considerable drop between 1981 and 2007, except for low fat and reduced spreads. Initially, butter was the most widely consumed spread, but it was overtaken by margarine during the 1991-2001 period. Low fat and reduced spreads, which first entered the market in 1996, eventually surpassed all other products to become the most consumed spread.
Regarding the specifics, butter was the leading spread in 1981, with approximately 140 grams consumed per person daily. It was followed by margarine at nearly 90 grams. In contrast, the consumption of low fat and reduced spreads did not begin until 1996, starting at roughly 10 grams. Thereafter, it rose sharply, peaking at 80 grams in 2001, and became the top spread before slightly declining to 10 grams less by 2007.
The consumption of butter and margarine fell dramatically over the 26-year period. More specifically, butter intake increased steadily to a peak of 160 grams per capita in 1986, after which it dropped continuously to about 55 grams by 2007. Margarine displayed a similar pattern with some fluctuations, declining from around 90 grams to 40 grams between 1981 and 2007.
