The given pie charts illustrate the average proportion in American typical meals of three types of nutrients, including sodium, saturated fat and added sugar.
Overall, it is obvious that dinner contains the highest content of sodium and saturated fat, while the percentage of added sugar mainly comes from snacks.
Regarding the amount of sodium, the major proportion of this nutrient is from dinner, accounting for approximately three-quarters of the total, followed by that from lunch, at around a third. Meanwhile, the percentages of sodium from breakfast and snacks are equal, both at 14%.
In a similar fashion, the proportion of saturated fat also mainly comes from dinner, making up 37% of the total and exceeding that from lunch by 11%. In addition, the percentages of saturated fat from breakfast and snacks is relatively the same, at 16% and 21%, respectively.
In terms of added sugar, the proportion of this nutrient from snacks accounts for nearly a half of the chart, approximately three times that from breakfast. At the same time, the amount of saturated fat on lunch and dinner is both below a quarter.
