A nutrition label showing 23% DV for protein indicates that the food is an excellent source of protein.

• A. False
• B. True
• C. It depends on other nutrients
• D. Unrelated to protein quality

Answer: (B)

Percent daily value for protein shows how much of the daily protein intake a serving provides. The standard daily value for protein is 50 grams, so 23% DV means about 11.5 grams of protein per serving. The FDA defines an excellent source of a nutrient as providing 20% DV or more in a serving, so 23% clearly meets that criterion for protein. So the statement is correct: a 23% DV for protein on a nutrition label indicates an excellent source of protein. This reflects quantity relative to daily needs, not the protein’s quality. The other options aren’t necessary here; the point is about the DV percentage indicating an excellent source, not about false labeling or about interactions with other nutrients.
