Explanation in Detail:
The statement "Daily value has not been established" is often found on food labels or nutritional information. It indicates that the specific amount or percentage of a nutrient that contributes to a healthy diet has not been determined or officially set. This lack of establishment could be due to various reasons, such as ongoing research, changes in dietary recommendations, or differences in standards between countries or organizations.

In the context of food labels, the daily value is often expressed as a percentage (% DV) and provides consumers with information about the nutritional content of a particular food item. It helps individuals make informed choices about their dietary intake and understand the contribution of specific nutrients to their overall health.

However, for some nutrients, such as certain vitamins, minerals, or other bioactive compounds, there may not be enough scientific evidence or consensus to establish a specific daily value. In such cases, the daily value may be listed as "not established" or simply not provided on the label.

Conclusion:
In summary, the word "established" means to set up, create, determine, or fix something with authority. In the context of the statement "Daily value has not been established," it refers to the fact that a specific daily value for a nutrient has not been determined or fixed. This lack of establishment may be due to various reasons, such as ongoing research or differences in standards.
