Responsibilities and Activities: A Deep Dive
The Food and Nutrition Board shoulders several critical responsibilities, all aimed at providing sound nutritional guidance. A cornerstone of the FNB’s work is the development and continuous refinement of Dietary Reference Intakes (DRIs). The Dietary Reference Intakes are a comprehensive set of nutrient reference values for healthy populations. They encompass several categories, including Recommended Dietary Allowances (RDAs), Adequate Intakes (AIs), Tolerable Upper Intake Levels (ULs), and Estimated Average Requirements (EARs). Understanding these different values is crucial for interpreting nutrition information and planning healthy diets.
Understanding DRI Values
The Recommended Dietary Allowances (RDAs) represent the average daily intake level sufficient to meet the nutrient requirements of nearly all (97-98%) healthy individuals in a particular life stage and gender group. When sufficient scientific evidence is lacking to establish an RDA, an Adequate Intake (AI) is established instead. The Adequate Intake is an estimated value based on observed or experimentally determined nutrient intakes by a group of healthy people. The Tolerable Upper Intake Level (UL) represents the highest average daily nutrient intake level that is likely to pose no risk of adverse health effects to almost all individuals in the general population. Finally, the Estimated Average Requirement (EAR) is the average daily nutrient intake level estimated to meet the requirements of half of the healthy individuals in a group.
The process of establishing Dietary Reference Intakes is a meticulous and rigorous undertaking. It involves an extensive review of the scientific literature, including observational studies, clinical trials, and animal research. Expert panels, composed of leading nutrition scientists, are convened to evaluate the evidence and develop recommendations. These panels consider factors such as age, gender, physiological state (e.g., pregnancy, lactation), and potential interactions between nutrients. The resulting Dietary Reference Intakes serve as essential benchmarks for nutrition professionals, policymakers, and individuals seeking to optimize their nutrient intake. The Food and Nutrition Board also provides guidance on food fortification.
Guidance on Food Fortification
The Food and Nutrition Board’s expertise is frequently sought when it comes to advising on food fortification policies. Food fortification, the practice of adding nutrients to foods, can be an effective strategy for addressing nutrient deficiencies in a population. The Food and Nutrition Board plays a crucial role in evaluating the scientific evidence supporting fortification and recommending appropriate levels of nutrient addition. Successful food fortification programs, such as the addition of folic acid to grain products to prevent neural tube defects and the iodization of salt to prevent iodine deficiency disorders, demonstrate the positive impact of these interventions. The FNB’s guidance ensures that fortification efforts are safe, effective, and targeted to the populations most in need.
Responding to Nutrition Issues
The Food and Nutrition Board also responds to emerging nutrition issues. The field of nutrition is constantly evolving, with new scientific discoveries and emerging public health concerns. The Food and Nutrition Board is committed to staying abreast of these developments and providing timely and evidence-based guidance.
