Understanding Daily Value (DV) on Nutrition Labels

The Daily Value (DV) is a reference amount of nutrients to consume or not to exceed each day. It's a crucial tool found on the Nutrition Facts label of packaged foods, helping you understand the nutrient content of a serving of food in the context of a total daily diet.

What is the Daily Value (DV)?

Daily Values are based on a 2,000 calorie daily diet for general nutrition advice for adults and children aged 4 and older. While your individual calorie needs may vary, the 2,000 calorie diet serves as a standard benchmark. The %DV on a food label tells you how much a nutrient in a serving of food contributes to a total daily diet.

  • 5% DV or less of a nutrient per serving is considered low. For nutrients like saturated fat, sodium, and added sugars, aim for foods with a low %DV.
  • 20% DV or more of a nutrient per serving is considered high. For beneficial nutrients like dietary fiber, vitamin D, calcium, iron, and potassium, aim for foods with a high %DV.

Why is Calculating Daily Value Important?

Using the %DV helps you make informed food choices quickly:

  • Compare Foods: Easily compare the nutrient content of different products.
  • Manage Diet: Identify foods that are high or low in specific nutrients you want to monitor (e.g., low sodium for blood pressure, high fiber for digestive health).
  • Achieve Balance: Ensure you're getting enough of essential vitamins and minerals while limiting nutrients like saturated fat, sodium, and added sugars.

How to Use This Daily Value Nutrition Calculator

Our Daily Value Nutrition Calculator simplifies the process of understanding the nutritional impact of your food. Here's how to use it:

  1. Locate Nutrition Facts: Find the Nutrition Facts label on your food product.
  2. Enter Nutrient Amounts: For each nutrient listed in the calculator (e.g., Total Fat, Sodium, Protein, Vitamin D), enter the 'Amount Per Serving' from the food label into the corresponding input field.
  3. Click 'Calculate Daily Values': The calculator will instantly display the percentage of the Daily Value that one serving of your food provides for each nutrient.

For example, if a serving of your cereal has 3 grams of Dietary Fiber, and you enter '3' into the Dietary Fiber field, the calculator will show you that this serving provides approximately 11% of the recommended daily intake for fiber (based on the 28g DV).

Key Nutrients and Their Daily Values (Based on 2,000 Calorie Diet)

The calculator uses the following standard Daily Values, updated by the FDA:
