Final answer:
The best statement is Option C as it clearly connects the unhealthiness of soda with a specific example, emphasizing the high calorie content of sodas like Coca-Cola and the broader health implications associated with their consumption in schools.
Step-by-step explanation:
The improved version of the statement regarding the ban of soda from public schools is Option C: "Soda should be banned from public schools, because it is so unhealthy. For instance, a single can of Coca-Cola contains 140 calories." This version effectively uses the phrase 'For instance' to provide a specific example that supports the claim about soda's unhealthiness. The inclusion of a factual detail about the caloric content of a can of Coca-Cola strengthens the argument. Moreover, the caloric intake from sodas is significant, contributing to a lack of satiety and potential overconsumption of calories. This is backed by concerns about childhood obesity and the contribution of sugary beverages to health issues such as diabetes, heart disease, and dental problems.
As such, there have been regulatory moves, such as the Healthy, Hunger-Free Kids Act and Let's Move! Initiative, aimed at reducing access to soda and other sugary drinks in schools. In addition to regulations, promoting physical activity and healthy eating is pivotal in preventing obesity and related diseases.
