Which four facts must a food label contain?

A food label must provide critical information that helps consumers understand the nutritional content of the food product and how it fits into their daily dietary needs. The correct answer includes four essential facts: serving size, calories, fat, and percentage of daily value.

Serving size is important as it indicates how much of the product is considered a single serving; this helps consumers gauge their portion intake. Calories provide information on the energy content of the food, which is crucial for managing energy balance. The fat content is vital for understanding how much fat is in the product, influencing dietary choices related to health concerns like heart disease. Lastly, the percentage of daily value tells consumers how much of a nutrient in a serving contributes to a daily diet, helping individuals make informed choices about their nutrient intake relative to their daily needs.

These four components are foundational as they offer a summary of crucial nutritional facts, whereas the other options, while they may include some valuable information, do not encompass this essential combination mandated for comprehensive food labeling.
