Daily Value Formula:
From: | To: |
The Daily Value Calculator USA calculates the percentage of Daily Value (%DV) based on the amount of a nutrient and its US Recommended Daily Allowance (RDA). This helps consumers understand how much a serving of food contributes to their daily nutrient requirements.
The calculator uses the Daily Value formula:
Where:
Explanation: The equation calculates what percentage of the daily recommended intake is provided by a specific amount of a nutrient.
Details: %DV helps consumers make informed food choices, compare nutritional content between products, and maintain a balanced diet according to established nutritional guidelines.
Tips: Enter the nutrient amount in mg and the US RDA value in mg. Both values must be positive numbers greater than zero.
Q1: What is the difference between RDA and DV?
A: RDA (Recommended Dietary Allowance) is the daily intake level sufficient to meet nutrient requirements, while DV (Daily Value) is used on food labels to help consumers understand nutrient content in the context of a total daily diet.
Q2: What does 100% DV mean?
A: 100% DV means that one serving provides the entire recommended daily amount of that particular nutrient.
Q3: Are Daily Values the same for everyone?
A: No, Daily Values are based on average needs for adults and children over 4 years old. Individual needs may vary based on age, gender, and health status.
Q4: How should I use %DV information?
A: Use %DV to choose foods that are higher in nutrients you want more of (like fiber, vitamins) and lower in nutrients you want less of (like saturated fat, sodium).
Q5: Where can I find US RDA values?
A: US RDA values are established by the FDA and can be found on nutrition fact panels, dietary guidelines, or official FDA publications.
