Nutrient Reference Values (NRVs) serve as a guideline for the recommended daily intake of vitamins and minerals. They are intended to ensure that the basic needs of the general population are covered. But do they really ensure that we are optimally supplied? Or are they based on data from a population that is not in the best state of health?
The basis of the NRV
The determination of the NRVs is based on extensive scientific research and data analysis. The European Food Safety Authority (EFSA) has updated the reference values for 34 nutrients in a ten-year process to ensure that they correspond to the latest scientific knowledge EFSA . These values are intended to prevent deficiencies and support basic bodily functions.
average values for an average population
It is important to understand that NRVs represent averages based on the needs of a general population. They do not take into account individual differences such as age, gender, lifestyle, or specific health conditions. Furthermore, they often reflect the minimum requirement to avoid deficiencies rather than promoting the optimal amount for optimal health.
Criticisms of the current NRV
- Addressing suboptimal health conditions: Studies show that a significant portion of the world's population is inadequately supplied with essential micronutrients. One study found that more than half of the global population does not consume recommended amounts of nutrients such as calcium, iron, and vitamins C and E, according to the New York Post . This raises the question of whether current NRVs are sufficient to ensure optimal health.
- Minimum requirement orientation: The NRVs are designed to meet the minimum requirements to prevent deficiency symptoms. They do not necessarily aim to recommend the amounts that would be needed for optimal health or prevention of chronic diseases.
- Individual differences: People with increased nutrient requirements, such as athletes, pregnant women or people with certain diseases, may be undersupplied with the standardized NRVs.
The path to optimal health
For optimal health, it may be necessary to adjust individual nutrient intakes beyond the general NRVs. This can be achieved by eating a balanced diet rich in nutrient-dense foods. In some cases, targeted supplements may also be useful, particularly when specific deficiencies have been diagnosed or there is an increased need.
Conclusion
While the NRVs provide a valuable basis for preventing malnutrition, they should not be considered a universal recommendation for every individual. A personalized consideration of one's own nutritional needs, based on lifestyle, health status and individual goals, is critical to promoting optimal health.
