Final answer:
Dave Barry mentioned the sugar content the same as Cuba in his essay to humorously point out the high sugar consumption. Barry's writing style uses satire to highlight absurdities such as excessive sugar in products.
Step-by-step explanation:
Within Dave Barry's essay "Punch and Judy", he states the same sugar content as Cuba to make a humorous point about sugar consumption. Barry is known for his satirical writing style and therefore, the mention of sugar content is unlikely to be a commentary on the nutritional value or the importance of sugar in our diet. Instead, it is more plausible that Barry uses this comparison as a humorous way to illustrate the excessive amounts of sugar that are found in common products, much like the example provided where Life Saver candies are mentioned as being 95% sugar and their production uses over 100 tons of sugar each day.
