Which of the following statements on a food label gives the most valid and applicable information?

The statement regarding "20 grams of complex carbs per serving" provides specific and quantifiable nutritional information that can help individuals make informed dietary choices. This detail allows consumers to understand not only the carbohydrate content but also that these carbs are derived from complex sources, which are generally associated with longer-lasting energy and increased satiety compared to simple carbohydrates.

In contrast, while other statements contain useful information, they either convey less definitive information regarding health impacts or are vague. For instance, the amount of sugar is essential but does not distinguish between added sugars and naturally occurring sugars. The calcium percentage provides context regarding daily intake but lacks specifics on how that affects overall nutritional balance, and the statement about ingredients varying does not provide any nutritional information, rendering it less useful for dietary planning.
