The given line chart illustrates the intake amount of the three spreads between 1981 and 2007. Units are measured in grams.
As a general trend, there was a fluctuation among the three spreads. Butter was the highest amount consumed at the beginning of the survey, which was replaced by Margarine in 1991. Then, low fat and reduced spreads became the most popular spread in the final year.
At the start of the examination, butter was the most popular spread, over 140 grams, and reached a peak in 1986, at nearly 160 grams. In the subsequent years, the quantity of butter declined dramatically to roughly 50 grams in 2007. Margarine was the second most widely used in 1981, experienced an upward trend between 1981 and 1986, surpassed the share of butter, and became the highest amount of human intake in 1991. It remained stable for five years before falling slightly to under 80 grams at the end of the survey.
In contrast, low fat and reduced spreads only appeared in 1996 at about 10 grams. In the following years, it rocketed to more than 80 grams. Even though, it experienced a downward shift from 2001 to 2007, low fat and reduced spreads were still the most popular spreads to be used, at roughly 70 grams.
