The line graph illustrates the changes in prices of three different categories of products—fresh fruits and vegetables, sugar and sweets, and carbonated drinks—between 1978 and 2009.
Overall, the price of fresh fruits and vegetables showed the greatest increase over the period, rising significantly compared to other categories. In contrast, the prices of sugar and sweets, as well as carbonated drinks, experienced a more gradual increase, remaining below the general consumer price index.
At the beginning of the period in 1979, all product categories started at approximately the same price level. Over the following years, the prices of fresh fruits and vegetables rose significantly, surpassing the other categories around the mid-1980s. By 2009, this category experienced the most dramatic increase, reaching a value close to 330, which was well above the consumer price index.
In contrast, the prices of sugar and sweets, as well as carbonated drinks, increased at a slower pace. While both categories showed steady growth, their price changes remained lower than the overall consumer price index throughout the period. By the end of the timeline, sugar and sweets had risen to around 200, while carbonated drinks showed the lowest increase, remaining slightly above 150.
