The USDA recommends consuming less than 10 percent of daily calories from added sugars on a 2000-calorie diet; thus, the daily limit is approximately 12.5 teaspoons of added sugars, with the closest answer from the options provided being 10 teaspoons.
The USDA recommends that individuals following a 2000-calorie diet should limit their intake of added sugars to less than 10 percent of their total daily calories. Given that there are 4 calories in 1 gram of sugar, 10 percent of a 2000-calorie diet equates to 200 calories from added sugars. Since there are 16 calories in a teaspoon of sugar, this translates to a recommended daily limit of 12.5 teaspoons of added sugars.
However, this figure is not a precise option given in the question, and the closest appropriate option based on the information provided is 10 teaspoons (option b), which aligns with the American Heart Association's guidelines for an upper limit.
