Answer:
The best answer would be
Thesis statement: Americans consume large amounts of sugar in their daily diets, which leads to a variety of health problems.
Supporting details: The average American eats or drinks 82 grams of sugar a day, equaling 66 pounds of sugar each year per person. That is almost three times the recommended amount.
Step-by-step explanation:
This would be the best answer because you are being asked to talk about the effects of the high sugar intake the average American has on their diet. This thesis statement and supporting details perfectly address that.
In addition, the first thesis statement and supporting details would not be a good choice because it is only letting people know that most of the food they consume on the daily has lots of added sugar and that they should find other alternatives to get good sugars in their diet. Which would not be a good argument for your prompt as you have to address the problem of the average American eating too much sugar and why it is bad for their health.
Hope this helps clearing any other doubts :)
