Harmonized nutrient distribution -

However, with the increasing globalization of information and the identification of a variety of factors specific to different population subgroups e. There is a need for guidance and recommendations about methodological approaches, as well as their potential for application to an international process for the development of NRVs, and particularly for young children and women of reproductive age.

Harmonization of Approaches to Nutrient Reference Values: Applications to Young Children and Women of Reproductive Age examines these issues and makes recommendations for a unified approach to developing NRVs that would be acceptable globally.

Gibson RS 1 , Principles of Nutritional Assessment: Development of Nutrient Reference Values 3rd Edition March, Abstract This chapter describes the evolving process of setting nutrient reference values NRVs from a single value to a multi-level approach designed to address multiple users and needs.

This multi-level approach with some modifications has been adopted by several authoritative groups. However, discrepancies in the terminology and methodologies has led to an initiative to develop a four-step framework for harmonizing the process for deriving two core NRVs.

The feasibility of the proposed framework has been tested with three exemplar micronutrients zinc, iron, folate on two high-risk pop­ula­tion sub­groups — young children and women of reproductive age. The framework can be applied across countries and a variety of pop­ula­tion sub­groups, while taking into account culturally and context-specific food choices and dietary patterns.

Derivation of the two core NRVs depicted in the framework — the Average Requirement AR and Safe Upper Level of Intake UL — is presented here. Details of additional NRVs used are also described. Details of the different methods used to establish recommendations for energy and macronutrients are also described.

Two core nutrient intake reference values NRVs Harmonized nutrient distribution required for assessing the adequacy and safety of Harmonized nutrient distribution intakes for Harmonizde groups: the average requirement AR and Harmonized nutrient distribution tolerable disgribution level of intake UL.

However, there is a lack of unity across country-level organizations in the methodological approach used to derive NRVs, and ARs and ULs are lacking in many compilations, thus limiting the ability to assess nutrient intakes for their population groups. Because physiological requirements vary little across populations globally, and setting reference values requires determining an acceptable level of uncertainty, it is feasible to adapt current recommendations from different sources to harmonize these core reference values. The objective of this review is to demonstrate an approach for harmonizing the NRVs for ARs here termed "H-ARs" and ULs "H-ULs" that can be applied on a global scale to assessing intakes across populations. The approach incorporates the framework and terminology recommended by reports from the United Nations University, the National Academies of Sciences, Engineering, and Medicine NASEMthe Institute of Medicine IOMand the European Food Safety Authority EFSA.

New article available: An Algorithm to Assess Calcium Bioavailability from Foods. This project aims to facilitate regional adaptations of harmonized or regional nutrient requirements. Globally harmonized nutrient recommendations or HAR or regional recommendations need to be adjusted for bioavailability for many micronutrients. Algorithms that consider absorption enhancers and inhibitors such as oxalate and phytate for minerals can be used in formulation and labeling the bioavailable nutrient content per serving, to assess and plan intakes of population groups globally, to provide a common basis for comparing the nutrient intake of populations, and to develop national and regional strategies for ameliorating nutrient deficiencies.

The Inadequacy of Specific Micronutrient Intake is an Harmonjzed that estimates the percent nturient a given population that is at risk Harmonizd inadequate Harmonuzed for a specific micronutrient.

Both Cancer-fighting superfoods of calculating this dustribution require nutrient intake data for a population that has been adjusted to represent distrlbution distribution of "usual" nutrient intakes.

To provide accurate estimates of the percent of a population at risk distributiom inadequate intake, Harmonized nutrient distribution intakes either hour Dietary Recall or Weighed Food Records are required on at least a sub-sample of the population, in order to account for day-to-day variation.

The EAR fixed cut-point Harjonized plots the EAR value onto the distribution of "usual" nutrient intakes to establish a cut-point, and calculates the percent of intakes that fall below that point to estimate the percent of the population at risk of inadequate intakes.

The EAR for a nutrient is its estimated average requirement for a population i. See Figure 1 below for a visual representation of this method:. Source: Institute of Medicine, The probability approach uses intake data from the study population to construct a distribution of intakes for that population, and uses this distribution of intakes along with the distribution of "usual" requirements to estimate the percent at risk of inadequate intakes in the population.

See Figure 2 below for a visual representation of this method:. The probability of inadequacy can be manually calculated as a weighted average of the risk of inadequacy at each potential level of intake.

To perform this calculation, the requirement distribution is divided into categories based on gender and age, and the number of people from the population with nutrient intakes falling into each category is determined and multiplied by the probability of inadequacy for that category.

These values are summed across all categories and then divided by the total population and multiplied by to estimate the percent at risk of inadequate intake in the population. For an explanation of situations in which the EAR fixed cut-point method can be used, refer to Box in theDietary Reference Intakes DRI document Institute of Medicine [IOM], For a list of nutrients for which the probability approach can be used, refer to Table in the same document IOM, For more detail on using both the probability and cut-point methods for estimating inadequacy, refer to Chapter 4 of the DRI document IOM, This indicator is used to estimate the percent of a given population that is at risk of inadequate intakes of individual nutrients, so it can be used to identify the need for nutrient-specific interventions such as fortification or supplementation.

The main strength of this method is that it provides an estimate of the percent of a population that is at risk of inadequate intake of specific nutrients.

Although this indicator does not provide a measure of overall dietary adequacy in a single index, it does provide a measure of overall dietary adequacy when the percent at risk of inadequate intakes is calculated for multiple nutrients separately.

A weakness, however, is that this indicator requires an EAR, which is unknown for certain nutrients, and is unknown for most nutrients during infancy. In addition, the DRIs for many nutrients, such as iron and zinc, vary depending on the assumed absorption, which can differ depending on the type of food consumed.

Therefore, this indicator and any others that rely on nutrient requirements can only estimate the risk of inadequate nutrient intake, rather than confirming deficiency. Although this indicator uses individual-level dietary data, it can only be used to estimate risk of inadequate intake at the population level, and cannot be used to identify individuals who are deficient or at risk of inadequacy Yates et al.

The data used to estimate the "usual" distribution of intakes for a nutrient are collected using quantitative dietary assessment techniques, such as repeated hour Dietary Recallsmultiple- day Weighed Food Recordsor quantitative Food Frequency Questionnaireswhich are then translated into nutrient intakes using national or regional Food Composition Tables.

As noted above, repeated intakes are required on at least a sub-sample of the population. Food Composition Tables can be found at FAO's International Network of Food Data Systems INFOODS or the World Nutrient Databases for Dietary Studies WNDDSdeveloped by the Agricultural and Food Systems Initiative, now known as the Agriculture and Food Systems Institute.

EARs can be obtained from the Institute of Medicine IOM,or other country-specific national sources.

Data source and retrieval We selected and retrieved data for a total of 31 N- and P-based nutrient compounds primarily associated with agricultural runoff from the WQP. We publish prepublications to facilitate timely access to the committee's findings. The Methods section is divided into two subsections: i Data source and retrieval, and ii Data harmonization. Recommended intake levels for nutrients and other dietary components were designed initially to prevent nutrient deficiency diseases in a given population, and the original methodological approach used to derive intake values did not include consideration for other applications.

These may include baseline risk for chronic disease by an individual, nutrient-diet or nutrient-nutrient interactions, and environmental and other lifestyle factors; Chronic diseases develop over a long period making it difficult to accurately measure dietary patterns over such a long period of exposure; Published intervention trials are often conducted in selected sub­groups, such as individuals with an already increased risk of disease or history of disease, frequently with intervention dosages that are relatively high and which have relatively short follow-up periods.
