Enhance the accuracy and precision of dietary survey data to meet research needs through improvements to data collection methods. Sub-objective 3-3. Document and report changes to dietary data collection methods in concert with WWEIA data releases. Objective 4. Analyze and interpret results from nationwide dietary surveys focusing research on topics to include nutritional adequacy of the American population and at-risk sub-groups, dietary patterns, interrelationships between food component intakes, public health nutritional concerns, and/or policy implications. Sub-objective 4-1. Assess and report on dietary status and nutritional adequacy of U.S. population and population subgroups. Sub-objective 4-2. Serve as expert resource in use of the dietary survey data. Approach (from AD-416): The USDA AMPM is being used to collect 10,000 dietary recalls yearly in What We Eat In America, the dietary interview component of the National Health and Nutrition Examination Survey. The Food Surveys Research Group, having the lead responsibility for the dietary assessment component of NHANES, will focus on developing and implementing methods such that 1) the dietary collection method collects accurate data and is valid, 2) the data collected meet stakeholder needs and are released in a timely fashion, 3) the systems for data collection and processing are technologically advanced and efficient, 4) the dietary databases to support data analyses are scientifically sound and current so as to reflect the U.S. food supply at the time of data collection, 5) the data are interpreted and reported to address critical and pressing policy issues of the time, and 6) the applications developed for collection and processing are made available to the fullest extent possible. Special purpose databases to support specialized research policy needs, including the Food Patterns Equivalents Database used to assess American diets in relation to the Dietary Guidelines for Americans, will be developed and maintained. Through an ongoing collaboration with the National Center for Health Statistics, DHHS, the Food Surveys Research Group (FSRG) has the lead role for dietary data collection and processing of What We Eat in America (WWEIA), NHANES. Web release of WWEIA, NHANES 2015-2016 is on schedule for fall of 2018, providing the eighth release of national dietary data from this collaboration. The new data will provide information on dietary intakes of 10,000 individuals based on 24-hour dietary recalls statistically weighted to be representative of the population during the collection years. The data includes extensive detail on the description and amount of foods and beverages consumed over two 24-hour periods for each individual. Further information such as additions to the food or beverage, items eaten together, time each item was consumed, name of eating occasion, source of where obtained, and if it was eaten at home are also provided. The corresponding Food and Nutrient Database for Dietary Studies (FNDDS) 2015-2016, that provides the 65-nutrient profile for each food and beverage in WWEIA, will also be released in 2018. The FNDDS, used to analyze dietary intakes from WWEIA, is also used by nutrition researchers in their dietary studies. Data collection for the 2017 WWEIA, NHANES is ongoing. FSRG conducted training sessions and quality control oversight for data collection and coding performed by the NHANES contractor. Onsite visits to select NHANES sites across the U.S. were made by FSRG to conduct quality review of dietary data collection. The USDA 5-step Automated Multiple-Pass Method (AMPM), the computer- based instrument used to collect 24-hour dietary recalls in WWEIA, has thousands of questions and subsequent response options specific to the variety of foods and beverages consumed in the U.S. These questions, grouped by 130 pathways, require review and update. Major revision was completed for 15 pathways for the 2017-2018 collection years. The survey food database used by the NHANES contractor to code reported foods/ beverages and their amounts was updated for the 2017-2018 collection years with data on new items and changes to current foods/beverages. The FNDDS 2013-2014, used to convert food and beverages consumed in 2013- 2014 WWEIA, NHANES into gram amounts and to determine their nutrient values, was released on the FSRG Web site www.ars.usda.gov/nea/bhnrc/fsrg. The release consisted of 11 interrelated data files including more than 8,500 foods and beverages, their detailed descriptions, values for energy and 64 nutrients and source designation for each value, and 40,000 portions and weights. FNDDS is also used in other dietary studies to code foods/beverages and amounts eaten and to calculate the amounts of nutrients/food components in those items. A 2013-2014 FNDDS Fortification Designation File has been developed to designate those foods/beverages that are either fortified or are made up of fortified components. This file provides a tool for researchers assessing the impact of fortification on nutrient intakes of the U.S. population. With each release of the FNDDS, a notable increase in the number of food/ beverage codes is added; additionally, codes are discontinued which can pose challenges for researchers. FSRG researchers developed a special crosswalk file of code changes and linkages between FNDDS 2011-2012 and 2013-2014. The file identifies changes to codes--discontinued, expanded, or consolidated. The availability of a resource to crosswalk appropriate discontinued food/beverage codes between FNDDS versions benefits researchers conducting trend analysis or using the FNDDS to support other food intake databases. The file is available on the FSRG Web site www. ars.usda.gov.nea/bhnrc/fsrg. The WWEIA Food Categories 2013-2014 were developed, an application to analyze foods and beverages as consumed in the American diet. Each of the food and beverage items that can be reported in the national survey is sorted into 152 unique food categories. Designed to be flexible, the categories can be combined to address specific research questions. A new version of the WWEIA Food Categories is produced for each 2-year release cycle of NHANES and available on the FSRG Web site www.ars.usda.gov/nea/ bhnrc/fsrg. Uses of the WWEIA Food Categories have included development of food guidance programs and educational materials, monitoring food intake, and identifying food trends and food/beverage sources of nutrients. Data tables summarizing dietary intakes of the U.S. population can readily be used by government groups, nutrition researchers, and the general public. FSRG researchers have analyzed dietary and supplement use data from WWEIA, NHANES 2013-2014 and developed 4 tables summarizing nutrient intakes from food and beverages and dietary supplements for 22 select vitamins and minerals. Estimated means and standard errors by supplement users, nonusers, and all individuals are provided for 11 age/ gender groups as well as race/ethnicity, family income, and poverty level. The tables are available on the FSRG Web site www.ars.usda.gov/ba/bhnrc/ fsrg. The availability and enhanced accessibility of these new tables are a benefit to users in need of current population-level information on total nutrient intakes of Americans. Analysis of the WWEIA data was completed to construct dietary data briefs and research articles on a variety of topics including sodium intake, trends and use of discretionary salt at the table and in cooking, phosphorus intake, sodium/ potassium ratios, Food Patterns Equivalents Database (FPED) components, and methods to estimate fruit and vegetable intakes. The FPED 2013-2014 was developed and released on the FSRG Web site www. ars.usda.gov/nea/bhnrc/fsrg. FPED serves as a unique research tool to evaluate food and beverage intakes of Americans compared to recommendations of the 2015-2020 Dietary Guidelines for Americans (DGA). The FPED 2013-2014 converts foods and beverages in the WWEIA, NHANES 2013- 2014 to equivalent amounts of the 37 USDA FP Components, including added sugars and whole grains. Summary table sets on mean intakes of the 37 FP components by 23 age-gender and socioeconomic subgroups for 2013-2014 have also been developed and released. The DGA 2015-2020 recommend that Americans limit their added sugars intake to less than 10 percent of daily calories and increase their fruit, vegetables, and whole grains intakes. To determine how dietary intakes of Americans fare in meeting these recommendations, FSRG researchers have analyzed changes in the U.S. population�s intake of selected USDA FP components, including added sugars and solid fats, using WWEIA, NHANES 2003-2004 and 2013-2014 dietary data. Results show added sugars intake has decreased from 21 to 17.4 teaspoon equivalents, and solid fats intake from 47.6 to 35.3 grams, respectively. Less than half of Americans (42%) met the 2015-2020 DGA recommendation for added sugars intake. Those who met the recommendation consumed 6.7 teaspoon equivalents of added sugars; those who did not consumed 25.1 teaspoon equivalents. No changes were noted in the fruit; vegetables; dairy; and total meat, poultry, and seafood intakes between 2003-2004 and 2013-2014. Two dietary data briefs reporting these results have been published on the FSRG Web site www.ars. usda.gov/nea/bhnrc.fsrg. The DGA 2020 will have an additional focus on children from birth to 24 months of age. FSRG researchers analyzed dietary intakes reported by mothers of 469 toddlers age 1-2 years in WWEIA, NHANES 2011-2012. Usual nutrient intakes of vitamins D and E were less than the recommended intake levels by 86% and 62% of toddlers, respectively. Almost all toddlers (96%) had usual intakes less than the recommendations for dietary fiber and potassium, and 71% exceeded the upper level for sodium. Mean daily intake of added sugars was 10% of daily energy intake, with approximately 40% of toddlers exceeding that level. Snack occasions contributed one-third of their daily energy intake; beverages contributed one-fourth. Milk, water, and 100% fruit juice were the top beverages consumed by toddlers. Soft drinks were consumed by 14% of toddlers. A greater proportion of toddlers consumed fruit (71%) compared with vegetables (57%). Nearly 1 in 3 toddlers consumed candy, and 2 in 5 consumed cakes/cookies/pastries. More than one-third consumed savory snacks, including chips, popcorn, and pretzels, and an equal proportion consumed crackers. These data will help formulate future recommendations for this age group. FSRG researchers have quantified flavonoid intakes of the U.S. adult population and analyzed associations between dietary flavonoid intake and health outcome measures collected in NHANES 2007-2010. Associations between flavonoid intake and anthropometric measures indicative of high cardiovascular disease risk showed an inverse relationship with intake of total flavonoids and three flavonoid classes. These findings, obtained using a large, nationally representative sample, concur with those of cohort studies which support the benefits of flavonoids on human health. FSRG collaborates with scientists at the National Institute on Aging�s Healthy Aging in Neighborhoods of Diversity Across the Life Span Study (HANDLS), a representative 20-year longitudinal study across the lifespan focused on investigating the differential influences of race and socioeconomic status on health. The study sample (4,000 participants) includes European-Americans and African-Americans 30-64 years of age from both low and high socioeconomic strata residing in Baltimore City, MD. FSRG researchers collaborated on the dietary data collection providing scientific and technical oversight. The AMPM and related coding and processing programs are used by HANDLS for assessing dietary intakes of study participants. Accomplishments 01 Release of national estimates of daily intakes of Food Pattern components based on WWEIA (What We Eat in America), NHANES (National Health and Nutrition Examination Survey) 2013-2014. Foods and beverages reported in national dietary surveys NHANES (National Health and Nutrition Examination Survey) and WMEIA (What We Eat in America), have been separated into 37 Food Pattern components to report on individual amounts consumed of those components. Four sets of tables have been released on the Web that summarize food and beverage intakes across the 37 Food Pattern components for 23 age-gender and socioeconomic groups for national dietary survey data conducted in 2013- 2014. These estimates provide the only unique data to evaluate food and beverage intakes of Americans compared to recommendations of the 2015-2020 Dietary Guidelines for Americans. The Food Patterns Equivalents Database (FPED) that converts foods reported in the 2013- 2014 survey as well as the Methodology and User Guide for FPED were also released on the Web at the USDA site. 02 Release of two dietary data briefs assessing added sugars intake and changes in food intakes over time by Americans. The Dietary Guidelines for Americans 2015-2020 recommend that Americans limit their added sugars intake to less than 10 percent of daily calories. Less than half of Americans (42%) met that recommendation. Those who met this recommendation consumed 6.7 teaspoon equivalents of added sugars compared to four times that amount (25.1 teaspoon equivalents) for those who did not. Although many Americans were not meeting this added sugars recommendation, results between 2003-2004 and 2013-2014 show there has been a decrease in mean daily added sugars intake, from 21 to 17.4 teaspoon equivalents, respectively. Intakes of solid fats during this 10-year period have also decreased, from 47.6 to 35.3 grams, respectively. However, no changes were noted in the fruit; vegetables; dairy; and total meat, poultry, and seafood intakes. These data briefs are accessible on the Web at the USDA site. 03 Update and release of the Food and Nutrient Database for Dietary Studies. The USDA Food and Nutrient Database for Dietary Studies 2013- 2014 (FNDDS) was released on the Web. The FNDDS is an extensive database used to convert food and beverages reported consumed in typical household measures in the 2013-2014 WWEIA, NHANES into gram amounts and to determine their nutrient values. It is used to code foods and portion sizes and to calculate nutrients. FNDDS contains information for nearly 8,000 foods and beverages. Values for food energy and 64 other nutrients are included for each item, as well as weights for common portions of the item. Nutrient values for items in FNDDS are derived from the USDA National Nutrient Database for Standard Reference 28. New versions of FNDDS are released every two years to accompany the release of the WWEIA, NHANES data. This update (version 2013-2014) of FNDDS was used to process dietary intakes from WWEIA, NHANES 2013-2014. The database is also a valuable research tool for scientists conducting studies that collect food intake data. The database is accessible on the Web at the USDA site. 04 Release of national estimates on summary dietary data tables. For each 2-year survey data release, What We Eat in America (WWEIA), National Health and Nutrition Examination Survey (NHANES) dietary intake data are analyzed and results released on the Web. Further analysis has been conducted by ARS researchers in the Beltsville Human Nutrition Research Center, Beltsville, Maryland, resulting in the release of an additional 4 summarized tables. These additional tables report nutrient intakes from food and beverages and dietary supplements for 22 select vitamins and minerals. These tables facilitate quick comparisons of nutrient intakes between the age/gender, race/ethnicity, and income groups. Data tables summarizing dietary intakes of the U.S. population can readily be used by government groups, nutrition researchers, and the general public. All summarized data tables are accessible from www. ars.usda.gov/nea/bhnrc/fsrg.

Sub-objective 4-1. Assess and report on dietary status and nutritional adequacy of U.S. population and population subgroups. Sub-objective 4-2. Serve as expert resource in use of the dietary survey data. Approach (from AD-416): The USDA AMPM is being used to collect 10,000 dietary recalls yearly in What We Eat In America, the dietary interview component of the National Health and Nutrition Examination Survey. The Food Surveys Research Group, having the lead responsibility for the dietary assessment component of NHANES, will focus on developing and implementing methods such that 1) the dietary collection method collects accurate data and is valid, 2) the data collected meet stakeholder needs and are released in a timely fashion, 3) the systems for data collection and processing are technologically advanced and efficient, 4) the dietary databases to support data analyses are scientifically sound and current so as to reflect the U.S. food supply at the time of data collection, 5) the data are interpreted and reported to address critical and pressing policy issues of the time, and 6) the applications developed for collection and processing are made available to the fullest extent possible. Special purpose databases to support specialized research policy needs, including the Food Patterns Equivalents Database used to assess American diets in relation to the Dietary Guidelines for Americans, will be developed and maintained. Through an ongoing collaboration with the National Center for Health Statistics, DHHS, the Food Surveys Research Group (FSRG) has the lead role for dietary data collection and processing of What We Eat in America (WWEIA), NHANES. Web release of WWEIA, NHANES 2013-2014 is on schedule for fall of 2016, providing the seventh release of national dietary data from this collaboration. The new data will provide information on dietary intakes of 10,000 individuals based on 24-hour dietary recalls weighted to be representative of the population. The corresponding Food and Nutrient Database for Dietary Studies (FNDDS) 2013-14, used to analyze dietary intakes, will also be released in 2016. The FNDDS, used to analyze dietary intakes from WWEIA and by nutrition researchers in their dietary studies, will include a 65-nutrient profile for each of more than 13,000 foods and beverages. FSRG conducted quality control oversight for dietary data collection, coding, and processing for WWEIA, NHANES 2016. The review and update of questions and response options for 15 pathways in the USDA 5-step Automated Multiple-Pass Method (AMPM), used to collect 24-hour dietary recalls in WWEIA, was also completed for the 2017 and 2018 data collection years. To ensure that supporting survey food databases are current and reflect changes in the U.S. food market, selected food and beverage categories were reviewed to check for new foods, changes to current foods in the database, and new portion sizes. Analysis of the WWEIA data was completed to construct dietary data briefs and research articles on a variety of topics including: beverage intakes; trends in sodium intake; trends and use of discretionary salt at the table and in cooking; intakes of phosphorus, and assessing sodium/ potassium ratios; intakes of FPED components; comparison of methods to estimate fruit and vegetable intakes. The briefs and research articles are in various stages of peer review and finalization. The WWEIA Food Categories 2013-2014 was developed and released online to provide an application to analyze foods and beverages as consumed in the American diet. Each of the food and beverage items that can be reported in the national survey is sorted into approximately 152 unique and mutually exclusive food categories. Designed to be flexible, the categories can be combined as necessary to address specific research questions. A new version of the WWEIA Food Categories is produced for each 2-year release cycle of NHANES and available on the FSRG Web site www.ars.usda.gov/nea/bhnrc/fsrg. Potential uses of the WWEIA Food Categories include development of food guidance programs and educational materials, monitoring food intake, and identifying food trends. The Food Patterns Equivalents Databases (FPED) for 2013-2014 is being developed for release on the FSRG Web site www.ars.usda.gov/nea/bhnrc/ fsrg. The FPED corresponds with specific 2-year data releases of WWEIA, NHANES to provide the analytical basis for researchers to evaluate diets based on the recommendations of the 2015-2020 Dietary Guidelines for Americans. This release will have several products including a number of databases and summary table sets on the mean intakes of the 37 Food Patterns components by 23 age-gender and socioeconomic subgroups. The Database of Flavonoid Values for USDA Food Codes 2007-2010, the Flavonoid Intake Data Files from WWEIA, NHANES 2007-2010, and the Flavonoid Summarized Data Tables 2007-2010 are being developed for release on the FSRG Web site. This database provides flavonoid values for all foods/beverages in the USDA FNDDS versions 4.1 and 5.0, which correspond to dietary data from WWEIA, NHANES 2007-2008 and 2009-2010, respectively. Flavonoids, plant-based polyphenolic compounds, may play important roles in promoting health and preventing disease. It has been assumed that compliance with established national guidance to eat a diet rich in plant products is likely to result in an abundant intake of flavonoids. This database makes it possible to examine this theory in the U.S. population because flavonoid content profiles for all foods and beverages reported in WWEIA, NHANES 2007-2008 and 2009-2010. With these research products, researchers will be able to quantify dietary flavonoid intakes of the U.S. population and allow further investigation of associations between dietary flavonoid intake and health. They include estimates of 29 predominant dietary flavonoids categorized into 6 classes. Accomplishments 01 Release of national estimates on summary dietary data tables. For each 2-year survey data release, What We Eat in America (WWEIA), National Health and Nutrition Examination Survey (NHANES) dietary intake data are analyzed and results released on the Web including 56 summarized nutrient intake tables, providing summary statistics on dietary patterns and nutrient intakes in more than 700 pages. Data tables summarizing dietary intakes of the U.S. population can readily be used by government groups, nutrition researchers, and the general public. All summarized data tables are accessible from www.ars.usda.gov/nea/ bhnrc/fsrg. 02 Release of the WWEIA Food Categories. Each of the more than 8,000 foods and beverages in the Food and Nutrient Database for Dietary Studies has been linked to one of 152 WWEIA Food Categories. The WWEIA Food Categories provide an application for analyzing foods and beverages as consumed in the American diet. WWEIA Food Categories for 2013-2014 dietary data for WWEIA, NHANES were released on the Web by ARS researchers in the Beltsville Human Nutrition Research Center, Beltsville, Maryland, and are accessible from www.ars.usda.gov/nea/ bhnrc/fsrg. 03 Release of the Database of Flavonoid Values for USDA Food Codes 2007- 2010. This database provides the amounts of 29 flavonoids, 6 flavonoid classes, and total flavonoids present in 100 grams of each food and beverage in the USDA Food and Nutrient Database for Dietary Studies 4.1 and 5.0. The Flavonoid Database corresponds with the 2007-2008 and 2009-2010 WWEIA, NHANES. It provides an analytical basis for researchers to quantify dietary flavonoid intakes of the U.S. population and allows further investigation of associations between flavonoid intake and health. The release also includes a document describing the development of the database and SAS� datasets.

Enhance the protocol to track and identify market changes in foods and beverages to inform dietary data collection methodology. Sub-objective 3-2. Enhance the accuracy and precision of dietary survey data to meet research needs through improvements to data collection methods. Sub-objective 3-3. Document and report changes to dietary data collection methods in concert with WWEIA data releases. Objective 4. Analyze and interpret results from nationwide dietary surveys focusing research on topics to include nutritional adequacy of the American population and at-risk sub-groups, dietary patterns, interrelationships between food component intakes, public health nutritional concerns, and/or policy implications. Sub-objective 4-1. Assess and report on dietary status and nutritional adequacy of U.S. population and population subgroups. Sub-objective 4-2. Serve as expert resource in use of the dietary survey data. Approach (from AD-416): The USDA AMPM is being used to collect 10,000 dietary recalls yearly in What We Eat In America, the dietary interview component of the National Health and Nutrition Examination Survey. The Food Surveys Research Group, having the lead responsibility for the dietary assessment component of NHANES, will focus on developing and implementing methods such that 1) the dietary collection method collects accurate data and is valid, 2) the data collected meet stakeholder needs and are released in a timely fashion, 3) the systems for data collection and processing are technologically advanced and efficient, 4) the dietary databases to support data analyses are scientifically sound and current so as to reflect the U.S. food supply at the time of data collection, 5) the data are interpreted and reported to address critical and pressing policy issues of the time, and 6) the applications developed for collection and processing are made available to the fullest extent possible. Special purpose databases to support specialized research policy needs, including the Food Patterns Equivalents Database used to assess American diets in relation to the Dietary Guidelines for Americans, will be developed and maintained. Through an ongoing collaboration with the National Center for Health Statistics, DHHS, the Food Surveys Research Group (FSRG) has the lead role for dietary data collection and processing of What We Eat in America (WWEIA), NHANES. Web release of WWEIA, NHANES 2013-2014 is on schedule for 2016, providing the seventh release of national dietary data from this collaboration. The new data will provide information on dietary intakes of 10,000 individuals based on 24-hour dietary recalls weighted to be representative of the population. The corresponding Food and Nutrient Database for Dietary Studies (FNDDS) 2013-14, used to analyze dietary intakes, will also be released in 2016. The FNDDS, used to analyze dietary intakes from WWEIA and by nutrition researchers in their dietary studies, will include a 65-nutrient profile for each of more than 13,000 foods and beverages. FSRG conducted quality control oversight for dietary data collection, coding, and processing for WWEIA, NHANES 2015. The review and update of questions and response options for 36 pathways in the USDA 5-step Automated Multiple-Pass Method (AMPM), used to collect 24-hour dietary recalls in WWEIA, was also completed for the 2015 and 2016 data collection years. This review was the largest to the AMPM since it has been used in WWEIA, NHANES with more than a quarter of the 132 pathways updated. To ensure that supporting survey food databases are current and reflect changes in the U.S. food market, selected food and beverage categories were reviewed to check for new foods, changes to current foods in the database, and new portion sizes. Analysis of the WWEIA data was completed to construct dietary data briefs and research articles on a variety of topics including: breakfast, lunch, and dinner in America; beverage intakes; beverage intakes related to smoking status; trends in sodium intake; trends and use of discretionary salt at the table and in cooking; intakes of sodium and potassium, and assessing sodium/potassium ratios; vegetable intakes of children; intakes of FPED components; comparison of methods to estimate fruit and vegetable intakes; and trends in yogurt intake. The briefs and research articles are in various stages of peer review and finalization. The WWEIA Food Categories 2011-2012 was developed and released online to provide an application to analyze foods and beverages as consumed in the American diet. Each of the food and beverage items that can be reported in the national survey is sorted into approximately 150 unique and mutually exclusive food categories. Designed to be flexible, the categories can be combined as necessary to address specific research questions. A new version of the WWEIA Food Categories is produced for each 2-year release cycle of NHANES and available on the FSRG Web site www.ars.usda.gov/nea/bhnrc/fsrg. Potential uses of the WWEIA Food Categories include development of food guidance programs and educational materials, monitoring food intake, and identifying food trends. A Prototype Food and Nutrient Database for Dietary Studies (Prototype FNDDS) was developed as a proof of concept to demonstrate that data can be moved electronically from food manufacturers into the FNDDS. Label data in electronic format for a small selection of food products from 5 companies were provided to ARS through the Partnership for Public Health: Branded Food Products Database. The partnership is composed of USDA/ARS, the International Life Sciences Institute North America, and the Agricultural Technology Innovation Partnership Foundation. Label information included the manufacturer and brand, the Nutrition Facts Panel data, ingredients, serving size description and weight in grams, and dates for when a product is available, when it is discontinued, and when it is changed. Food manufacturers initiate the process when they put selected data about their foods in GS1, a global supply and trading system. Data are then sent through the Partnership for Public Health and incorporated into the Prototype FNDDS. Continuing the work of providing branded food product label data by food manufacturers and incorporating these data into FNDDS by ARS will greatly enhance dietary intake assessment in WWEIA, NHANES. The Food Patterns Equivalents Databases (FPED) for 2011-2012 were completed and released on the FSRG Web site www.ars.usda.gov/nea/bhnrc/ fsrg. The FPED corresponds with specific 2-year data releases of WWEIA, NHANES to provide the analytical basis for researchers to evaluate diets based on the recommendations of the 2010 Dietary Guidelines for Americans. This release has several products including a number of databases and summary table sets on the mean intakes of the 37 Food Patterns components by 23 age-gender and socioeconomic subgroups. Accomplishments 01 Release of national estimates on summary dietary data tables. For each 2-year survey data release, What We Eat in America (WWEIA), National Health and Nutrition Examination Survey (NHANES) WWEIA, NHANES dietary intake data are analyzed and results released on the Web including 40 summarized nutrient intake tables. Further analysis has been conducted by ARS researchers in the Beltsville Human Nutrition Research Center, Beltsville, Maryland, resulting in the release of an additional 16 summarized tables. These additional tables report nutrient intakes per 1000 kilocalories from food and beverages and from full service restaurants, quick service restaurants, and all restaurants. These two new sets of tables will facilitate quick comparisons of nutrient intakes between the age/gender, race/ethnicity, and income groups. Data tables summarizing dietary intakes of the U.S. population can readily be used by government groups, nutrition researchers, and the general public. All summarized data tables are accessible from www.ars.usda.gov/nea/bhnrc/fsrg. 02 Release of national estimates of daily intakes of Food Pattern components based on WWEIA, NHANES 2011-2012. Foods and beverages reported in national dietary surveys have been disaggregated into 37 Food Pattern components in order to report on amounts consumed of those components. Four sets of tables have been released on the Web that summarize food and beverage intakes across the 37 Food Pattern components for 23 age-gender and socioeconomic groups for national dietary survey data conducted in 2011-2012. These estimates provide unique data to evaluate food and beverage intakes of Americans compared to recommendations of the 2010 Dietary Guidelines for Americans. The Food Patterns Equivalents Database (FPED) that converts foods reported in the 2011-2012 survey as well as the Methodology and User Guide for FPED were also released on the Web; all are accessible along with the data tables from www.ars.usda.gov/nea/bhnrc/fsrg. 03 Release of the WWEIA Food Categories. Each of the nearly 8,000 foods and beverages in the Food and Nutrient Database for Dietary Studies has been linked to one of 150 WWEIA Food Categories. The WWEIA Food Categories provide an application for analyzing foods and beverages as consumed in the American diet. WWEIA Food Categories for 2011-2012 dietary data for WWEIA, NHANES were released on the Web and are accessible from www.ars.usda.gov/nea/bhnrc/fsrg.

Serve as expert resource in use of the dietary survey data. Approach (from AD-416): The USDA AMPM is being used to collect 10,000 dietary recalls yearly in What We Eat In America, the dietary interview component of the National Health and Nutrition Examination Survey. The Food Surveys Research Group, having the lead responsibility for the dietary assessment component of NHANES, will focus on developing and implementing methods such that 1) the dietary collection method collects accurate data and is valid, 2) the data collected meet stakeholder needs and are released in a timely fashion, 3) the systems for data collection and processing are technologically advanced and efficient, 4) the dietary databases to support data analyses are scientifically sound and current so as to reflect the U.S. food supply at the time of data collection, 5) the data are interpreted and reported to address critical and pressing policy issues of the time, and 6) the applications developed for collection and processing are made available to the fullest extent possible. Special purpose databases to support specialized research policy needs, including the Food Patterns Equivalents Database used to assess American diets in relation to the Dietary Guidelines for Americans, will be developed and maintained. Through an ongoing collaboration with the National Center for Health Statistics, DHHS, the Food Surveys Research Group (FSRG) has the lead role for dietary data collection and processing of What We Eat in America (WWEIA), NHANES. Web release of WWEIA, NHANES 2011-2012 is on schedule for late 2014, providing the sixth release of national dietary data from this collaboration. The new data will provide information on dietary intakes of 10,000 individuals based on 24-hour dietary recalls weighted to be representative of the population. The corresponding Food and Nutrient Database for Dietary Studies (FNDDS) 2011-12, used to analyze dietary intakes, will also be released in 2014. The FNDDS, used to analyze dietary intakes from WWEIA and by nutrition researchers in their dietary studies, will include a 65-nutrient profile for each of more than 13,000 foods and beverages. FSRG conducted quality control oversight for dietary data collection, coding, and processing for WWEIA, NHANES 2013 and 2014. The review and update of the USDA 5-Step Automated Multiple Pass Method, used to collect 24-hour dietary recalls in WWEIA, was also completed for implementation in 2015. To ensure that supporting survey food databases are current and reflect changes in the U.S. food market, selected food and beverage categories were reviewed to check for new foods, changes to current foods in the database, and new portion sizes. Analysis of the WWEIA data was completed to construct dietary data briefs on the following topics: dietary intake of calcium and fiber, consumption of pizza in the United States, lunch and dinner in America, beverage intakes, and added sugar intakes. The brief on consumption of pizza has been completed and released online. The remaining briefs are in various stages of peer review and finalization. The Provisional Flavonoid Addendum to the USDA FNDDS 4.1. and summary table set were completed and released online. Flavonoids, plant-based polyphenolic compounds, may play important roles in promoting health and preventing disease. Although it has been assumed that compliance with established national guidance to eat a diet rich in plant products is likely to result in an abundant intake of flavonoids, it has not been possible to examine this theory in the U.S. population because flavonoid content profiles were not available for all foods and beverages reported in WWEIA, NHANES. With the Flavonoid Addendum to FNDDS 4.1, it is now possible. The Flavonoid Addendum corresponds with the 2007-2008 WWEIA, NHANES to provide the analytical basis for researchers to quantify dietary flavonoid intakes of the U.S. population and allow further investigation of associations between dietary flavonoid intake and health. It includes estimates of 29 predominant dietary flavonoids categorized into 6 classes. The release also includes documentation describing the specifics of how the dietary flavonoid profiles were compiled. The Food Patterns Equivalents Database (FPED) for 2005-2006 was completed and released online. The FPED corresponds with specific 2-year data releases of WWEIA, NHANES to provide the analytical basis for researchers to evaluate diets based on the recommendations of the 2010 Dietary Guidelines for Americans. The release has several products including a number of databases and summary table sets on the mean intakes of the 37 Food Patterns components by 23 age-gender and socioeconomic subgroups. Development of FPED 2011-2012 for the WWEIA, NHANES 2011-2012 data is underway and planned for release by the end of 2014. Significant Activities that Support Special Target Populations: Collaboration in the Healthy Aging in Neighborhoods of Diversity Across the Life Span Study (HANDLS): The primary objective of HANDLS is to create a representative 20-year longitudinal study across the lifespan focused on investigating the differential influences of race and socioeconomic status on health. The study sample includes European- Americans and African-Americans 30-64 years of age from both low and high socioeconomic strata residing in Baltimore City, Maryland. Anticipating attrition rates over the life of the study, the initial sample was 4,000 participants. Food Surveys Research Group (FSRG) scientists have collaborated on the dietary component of HANDLS by providing scientific and technical support for the successful launch of dietary data collection that began in the fall of 2005. Numerous training sessions were conducted for HANDLS staff on the use of the USDA Automated Multiple Pass Method for collection of 24-hour recalls and SurveyNet for coding and analysis of dietary intake data. Once dietary data collection was underway, FSRG scientists have provided technical oversight of the data processing steps and systems, assuring data quality and integrity. Accomplishments 01 Release of national survey data from What We Eat in America, NHANES 2011-2012. Through an ongoing collaboration with the National Center for Health Statistics of DHHS, the Food Surveys Research Group (FSRG) has the leadership role for dietary data collection and processing of What We Eat in America (WWEIA), NHANES. FSRG is in the twelfth successful year of that agreement. New nationwide dietary intake data were collected in WWEIA for the years 2011-2012 and were released on the Web for public use. The data include information on dietary intakes of 8,519 individuals from two nonconsecutive days, 24-hour dietary recalls along with sample weights that can be used to make estimates about dietary intakes of the U.S. population. These data are used by Federal-level and state-level decision makers and researchers in such tasks as monitoring the nutritional adequacy of U.S. diets, modeling the impact of food fortification on nutrient intakes, estimating exposure of population groups to contaminants, developing dietary guidance, and assessing the demand for agricultural products. Linked with health indicators from other components of the NHANES, these data provide opportunities to study relationships between eating patterns and health conditions. The data are accessible from www.ars.usda.gov/ba/ bhnrc/fsrg. 02 Release of summary dietary data tables. WWEIA, NHANES dietary intake data have been analyzed and results have been released on the Web in summarized data tables and dietary data briefs. Forty tables were released for WWEIA, NHANES 2011-2012. The tables report nutrient intakes from food and the contribution of protein, carbohydrates, fat, and alcohol in the American diet as well as the following: percentage of nutrients contributed by foods eaten away from home, at breakfast, at lunch, at dinner, and as snacks; distribution of snack occasion; and distribution of meal patterns. They also provide dietary information for individuals ages 2 and older based on income level and ethnicity. 03 Update and Release of the Food and Nutrient Database for Dietary Studies. The USDA Food and Nutrient Database for Dietary Studies 2011- 2012 (FNDDS) was released on the Web. The FNDDS is an extensive database of foods as consumed in the U.S. that is used to code foods and portion sizes and to calculate nutrients for the large-scale Federal food consumption survey, What We Eat in America (WWEIA), the dietary intake component of the National Health and Nutrition Examination Survey (NHANES). FNDDS contains information for nearly 8, 000 foods and beverages. Values for food energy and 64 other nutrients are included for each item, as well as weights for common portions of the item. Nutrient values for items in FNDDS are derived from the USDA National Nutrient Database for Standard Reference 26. New versions of FNDDS are released every two years to accompany the release of the WWEIA, NHANES data. This update (version 2011-2012) of FNDDS was used to process dietary intakes from WWEIA, NHANES 2011-2012. The database is also a valuable research tool for scientists conducting studies that collect food intake data. The database is accessible from www.ars.usda. gov/ba/bhnrc/fsrg. 04 Release of the Provisional Flavonoid Addendum to the USDA FNDDS 4.1. This database provides the amounts of 29 flavonoids, 6 flavonoid classes, and total flavonoids present in 100 grams of each food and beverage in the USDA Food and Nutrient Database for Dietary Studies 4.1. The Flavonoid Addendum to FNDDS 4.1 corresponds with the 2007-2008 WWEIA, NHANES. It provides the first analytical basis for researchers to quantify dietary flavonoid intakes of the U.S. population and allows further investigation of associations between flavonoid intake and health. The release also includes a document describing the development of the database and SAS� datasets. The database is accessible from www. ars.usda.gov/ba/bhnrc/fsrg. 05 Release of summary dietary intakes data tables on flavonoid intake of the U.S. population in 2007-2008. WWEIA, NHANES 2007-2008 dietary intake data were analyzed for intake of dietary flavonoids and results have been released on the Web in summarized data tables. Seven tables were released reporting dietary flavonoid intakes from 29 predominant dietary flavonoids and 6 classes for all individuals ages 2 and older and 23 age-gender groups. The data tables are accessible from www.ars. usda.gov/ba/bhnrc/fsrg. 06 Release of national estimates of daily intakes of Food Pattern components based on WWEIA, NHANES 2005-2006. Foods and beverages reported in national dietary surveys have been disaggregated into 37 Food Pattern components in order to report on amounts consumed of those components. Four sets of tables have been released on the Web that summarize food and beverage intakes across the 37 Food Pattern components for 23 age-gender and socioeconomic groups for national dietary survey data conducted in 2005-2006. These estimates provide unique data to evaluate food and beverage intakes of Americans compared to recommendations of the 2010 Dietary Guidelines for Americans. The Food Patterns Equivalents Database (FPED) that converts foods reported in the 2005-2006 survey as well as the Methodology and User Guide for FPED were also released on the Web; all are accessible along with the data tables from www.ars.usda.gov/ba/bhnrc/fsrg. 07 Release of a dietary data brief. WWEIA, NHANES dietary intake data have been analyzed and results have been released on the Web in a dietary data brief. Data briefs are short reports focusing on a single topic summarizing key results from What We Eat in America. The topic for this year's brief is consumption of pizza. The availability of these data briefs is beneficial in providing dietary survey results to food and nutrition program policy and decision makers in Federal, state, and local government, researchers at academic institutions, nutrition scientists and educators, and food and agricultural specialists in industry. The data briefs are accessible from www.ars.usda.gov/ba/bhnrc/ fsrg. 08 Release of the WWEIA Food Categories. Each of the nearly 8,000 foods and beverages in the Food and Nutrient Database for Dietary Studies has been linked to one of 150 WWEIA Food Categories. The WWEIA Food Categories provide an application for analyzing foods and beverages as consumed in the American diet. WWEIA Food Categories for 2011-2012 dietary data for WWEIA, NHANES were released on the Web and are accessible from www.ars.usda.gov/ba/bhnrc/fsrg.
