Daily value意思

"Daily Value" (DV) is a term used on food labels in the United States to indicate the percentage of a daily nutrient intake that a serving of a food provides. The Daily Value is based on a 2,000-calorie diet and is intended to help consumers make informed choices about their dietary intake.

For example, if a food label lists a Daily Value percentage of 20% for a particular nutrient, it means that one serving of that food provides 20% of the recommended daily intake for that nutrient, based on a 2,000-calorie diet.

The Daily Value percentages on food labels can be useful for tracking nutrient intake, but it's important to remember that they are based on a 2,000-calorie diet, and individual calorie and nutrient needs can vary based on age, sex, weight, height, and physical activity level.
