Daily Value (DV) is a reference value on food labels that indicates the amount of a nutrient that is considered to be a good source of that nutrient. The DV is based on the Dietary Reference Intakes (DRIs), which are established by the Health and Nutrition Examination Survey (HANES) and the National Health and Nutrition Examination Survey (NHANES). The DRIs are a set of nutrient recommendations that are based on the latest scientific evidence. The DV is expressed as a percentage of the DRI for a given nutrient. Food labels also include a % Daily Value column, which shows the percentage of the DV that is provided by one serving of the food. This information can be helpful for consumers who are trying to make healthy food choices.
DV Stands for Daily Value
Daily Value (DV) is a term used in nutrition to represent the recommended daily intake of a particular nutrient based on a 2,000-calorie diet. It is listed on food labels to help consumers make informed choices about the foods they eat.
Categories of Daily Values
DVs are categorized into two groups:
-
Essential Nutrients: These are nutrients that the body cannot produce on its own and must be obtained from food. They include:
- Vitamins (e.g., vitamin A, vitamin C)
- Minerals (e.g., calcium, iron)
- Fatty acids (e.g., omega-3 fatty acids)
-
Non-Essential Nutrients: These are nutrients that the body can produce on its own or obtain from food in small amounts. They include:
- Sugars
- Starch
- Fiber
How to Use Daily Values
To use DVs effectively, follow these steps:
- Check the serving size: The DV is based on a specific serving size, so make sure to pay attention to the amount you are consuming.
- Compare to recommended intake: The DV indicates the recommended amount of a nutrient for a 2,000-calorie diet. Adjust your intake accordingly if you consume more or fewer calories than 2,000.
- Consider individual needs: DVs are general recommendations, and your individual needs may vary depending on age, sex, health status, and other factors.
Example: Daily Value of Vitamin C
The Daily Value for vitamin C is 60 mg. This means that a 2,000-calorie diet should provide 60 mg of vitamin C per day. If you consume a food with 100 mg of vitamin C, it would provide 167% of the DV.
Table: Daily Values for Selected Nutrients
| Nutrient | Daily Value (DV) |
|---|---|
| Vitamin A | 900 mcg RAE |
| Vitamin C | 60 mg |
| Calcium | 1,000 mg |
| Iron | 18 mg (for women), 8 mg (for men) |
| Sodium | 2,300 mg |
| Fiber | 25 g |
Question 1:
What is the meaning of DV in nutrition?
Answer:
DV stands for Daily Value, which is a reference value used to determine how much of a nutrient or dietary ingredient a person should consume each day. It is based on the recommended daily intake for a healthy adult.
Question 2:
What is the purpose of DVs in nutrition?
Answer:
DVs help consumers understand the nutritional content of food products and make informed choices about their diet. They provide a standardized measure of the amount of each nutrient or dietary ingredient in a serving of food, allowing for easy comparison between different products.
Question 3:
How are DVs established?
Answer:
DVs are set by health authorities, such as the Food and Drug Administration (FDA), based on scientific research and dietary recommendations. They consider factors such as the body’s requirements for specific nutrients, the prevalence of nutrient deficiencies, and the potential for adverse health effects associated with over- or underconsumption.
