Food guides are dynamic nutrition education tools based on current nutritio
n recommendations, data on foods consumed by the target population, and nut
rient content of those foods. As new nutrient/food recommendations are prop
osed, food guides must be reassessed to ensure that they continue to meet n
utrient objectives. A framework for conducting this assessment is described
, consisting of six major steps. The first two steps identify the specific
source and nature of a new nutrition standard and consider data on prevalen
ce of inadequate intakes in the population in order to establish research p
riorities among candidate issues.The third step assesses the ability of cur
rent food guide recommendations to meet the proposed new standard, leading
to a fourth step, ii needed, in which potential changes to the Food Guide a
re systematically explored. A fifth step considers the consistency of any p
otential food guide modifications with current objectives for practicality
and usefulness of the guide to its target audience. The final step recogniz
es that some nutrient recommendations may have no feasible dietary solution
, and supplements must be considered. As examples, this paper applies this
framework to determining implications for food guidance of the new Dietary
Reference Intakes for calcium, magnesium, and folic acid and presents optio
ns for consideration in providing individualized dietary guidance for speci
fic age groups regarding these nutrients. Application of this assessment fr
amework can help assure nutrition educators, researchers, and policy makers
that proposed modifications to food guidance are based on a systematic, do
cumented research process, consistent with established goals and objectives
of the Food Guide and with current nutritional data and recommendations. A
ssessment activities can help identify research needs for improved data on
nutrient composition of food and data on consumer understanding and applica
tion of food guidance principles. These activities can also help inform tho
se who establish nutrition standards or propose fortification levels of the
potential consequences of their recommendations for food-guide-based diet
patterns.
