Daily Value is a standard used in nutritional labeling.
The term "Daily Value" (DV) is not typically used in the psychology context. However, Daily Value is a term used in the field of nutrition and food labeling. It is a reference value that is used on food and dietary supplement labels to help consumers understand the nutrient content of a food in the context of a total daily diet. The Daily Value is based on a 2,000 calorie daily diet and is typically shown as a percentage (%DV) next to the nutrient content on the label.
For example, if a food product has 20% DV of iron, it means that one serving of the product contains 20% of the recommended daily intake of iron for an adult on a 2,000 calorie diet. The DV for various nutrients, such as fat, sodium, fiber, vitamins, and minerals, are set by the U.S. Food and Drug Administration (FDA) based on the latest scientific evidence and dietary guidelines.
The concept of Daily Value can be relevant to the psychology of food and nutrition, as individuals' dietary habits can impact their mental and emotional well-being. For example, a balanced and nutrient-rich diet can support cognitive function, mood regulation, and overall mental health.
