The authors include details about the changes in diets over time to inform readers about how sugar has transformed what we eat.
Answer: Option B.
Step-by-step explanation:
The passage that has been shown above in the question talks about the change in the diet of the consumers from time to time with the development in the technology and ways of using and developing sugar.
The sugar that we eat today and the form in which we eat it today, it was never the same thing many years ago. From around 1800 the way and form of consumption of sugar was entirely different from the way it is done in the form today in different food items. This is what the passage in the question talks about.
