Step 1 : Introduction to the question "What is the largest source of added sugar in American diets?"
...The largest source of added sugar in the diet of an average American is sugar-sweetened sodas or other beverages. This can be easily explained by the number of soda sales in the U.S. The soda industry reports that 8.9 billion cases of soda is an average yearly sales number. The American Journal of Public Health reports that a can of soda a day may age a human body by as many as 4.6 years. Harvard School of Public Health revealed its study showing a link between sugar-sweetened drinks and American deaths from such conditions as cancer, cardiovascular disease and diabetes.
