The line graph illustrates the percentage of UK adolescents following a vegetable diet from 1960 to 2020.
Overall, the proportion of adolescents adopting a vegetable diet experienced noticeable fluctuations. The percentage increased steadily from 1960, reaching a peak in the early 1980s, before undergoing a significant decline in the following decade. After reaching its lowest point in the 1990s, the trend showed some recovery in the 2000s and remained relatively stable with slight growth towards 2020.
In detail, the percentage of UK adolescents following a vegetable diet began at nearly 0% in 1960 and rose consistently to around 17% by the early 1980s. However, after this peak, the figure dropped sharply, falling to approximately 5% in the early 1990s. A minor increase was observed in the late 1990s, but the proportion remained low.
From the early 2000s, the percentage started to rise again, showing a steady upward trend. By 2010, it reached around 10%, and although there were minor fluctuations, it remained close to this level until 2020. Despite this increase, the figure did not return to its peak levels from the 1980s
