Because these values may change according to such variables as body weight, metabolism, and how active you are.
Daily Values
Daily values are general guides because they are based on average nutrient needs for a typical adult and may not account for individual variations in age, sex, activity level, and health status. Additionally, these values are designed to help consumers understand the nutritional content of foods in relation to a balanced diet, but individual requirements can vary significantly. Thus, while they provide a useful benchmark, they should not replace personalized dietary advice.

The reference values for nutrient intake used on food labels are typically based on established dietary guidelines, such as the Daily Values (DVs) set by health authorities like the FDA. These values indicate the recommended daily intake of various nutrients for a standard adult diet, often based on a 2,000-calorie daily intake. DVs help consumers understand the nutritional content of food in the context of their overall daily diet. Specific values can vary by nutrient and demographic factors, such as age and sex.
The Daily Reference Values are values for nutrients and food components for which no set of standards (e.g., the RDAs or US RDAs) previously existed ~ Reference Nutritional Assessment 4th edition Lee & Nieman pg 47
Daily values of nutrients are set by the FDA and are consideredAnswerthe amount needed to meet the needs of all Americans.the amount required to meet the needs of a person requiring 2,000 calories.the standard amount needed to meet the needs of a young man.the amount the USDA considers "healthy".
Daily values (DVs) on food labels provide a reference for the recommended daily intake of nutrients based on a 2,000-calorie diet, helping consumers understand how a particular food fits into their overall nutritional goals. These values serve as a guideline for the percentage of daily nutrients provided by a serving of the food, allowing for easy comparison between products. DVs can vary based on age, sex, and specific dietary needs, making them a useful tool for maintaining a balanced diet.
Daily values is the amount of nutrients needed in a day. Most people are on a 2000 calorie diet so on the side of food packages they show percent of fat in your daily value. What ever that number is, is 2000 divided by that number its complicated but its easy to understand once you do the math
