When a food label indicates "excellent source," it means that the food item provides 20% or more of the Recommended Daily Intake (RDI) or Daily Value (DV) for a specific nutrient per serving. This labeling is regulated by the Food and Drug Administration (FDA), which sets these criteria to help consumers identify foods that are rich in essential nutrients.

As a result, when a food carries this designation, it suggests that consuming the product can significantly contribute to meeting daily nutrient requirements, which is an important aspect of maintaining a balanced diet and promoting overall health. This designation is particularly valuable for individuals seeking to increase their intake of certain vitamins and minerals, while also allowing them to make informed choices about their nutrition.

The other options—focus on added sugars, high fiber content, and low calorie content—do not specifically relate to the "excellent source" claim and are unrelated to the percentage of daily nutrient values. These criteria may be pertinent to other health claims on food labels but do not define what qualifies as an "excellent source."
