Progress 10/15/12 to 04/08/15
Outputs
Target Audience: Target audiences reached during the full course of the project include the following: (1) Health and nutrition professionals: this was the primary target audience of the project. They were reached through several avenues, including the publication of four (4) research, review, or commentary articles in peer-reviewed journals (see Products section). This target was also reached through a webinar and orange grove tour and presentation conducted for and attended by nutrition and health professionals, primarily registered dietitians. (2) Consumers: reached through media reporting of the findings of a research study regarding consumer knowledge, perceptions and behaviors related to sugar in beverages. Media coverage included a news release through the University of Florida's media department, local coverage by the University of Florida's radio and local TV station, other coverage in the state of Florida (news story in the Lakeland Ledger newspaper), and national coverage through a Reuter's news article that was picked up by various other media outlets for online posting. Changes/Problems: Major changes included administrative changes with my position that lead to the early closure of this project. Other challenges/problems encountered were related to Objective #3, where significant changes in management and personnel assisting with the longitudinal dataset analysis put the project on hold for over a year. What opportunities for training and professional development has the project provided?

How have the results been disseminated to communities of interest? Consumers were reached through media reporting of the findings of a research study regarding consumer knowledge, perceptions and behaviors related to sugar in beverages. Media coverage included a news release through the University of Florida's media department, local coverage by the University of Florida's radio and local TV station, other coverage in the state of Florida (news story in the Lakeland Ledger newspaper), and national coverage through a Reuter's news article that was picked up by various other media outlets for online posting. These activities helped bring the research results to consumer communities who would not ordinarily have been made aware of the research results. What do you plan to do during the next reporting period to accomplish the goals?

Impacts
What was accomplished under these goals?
IMPACT: The primary impact of the project was to fill gaps in published research regarding 100% citrus juice. One such gap related to consumer knowledge about the various types of sugars contained in beverages. With impending recommendations regarding sugar intake, Nutrition Facts panel changes related to disclosure of sugars, as well as the impending 5-year update to the Dietary Guidelines for Americans, it was important to contribute to the literature in this area. Objective #1 helped fill that knowledge gap. Another important gap related to extending our knowledge of the health benefits associated with 100% orange and grapefruit juice consumption. Objective #2 helped fill that knowledge gap. The importance of filling these knowledge gaps was to provide health and nutrition professionals with information to allow them to make evidence-based dietary recommendations to their patients and clients regarding 100% orange/grapefruit juice consumption. Filling these knowledge gaps may also be important to those making updates to nutrition policy. Objective 1: Further investigate and report on consumer knowledge, perceptions, and behaviors with respect to the types of sugars in beverages. The major accomplishments for this objective were that I assisted in conducting an online consumer survey related to consumer attitudes and knowledge about sugars in various beverages, assisted with analyzing the data, and served as the primary author to prepare, submit, and publish the findings in a peer-reviewed journal. Although the resulting publication was targeted to health professionals and scientists, local and national media coverage extended the reach to consumers as well. Objective 2: Evaluate and communicate the associations between citrus juice consumption and health conditions and indicators through comprehensive review publications. There are five (5) major accomplishments for this objective: (1) Evaluation of the literature related to 100% fruit juice consumption and nutritional benefits as well as associations with body weight. I served as the primary lead study evaluator and lead author of a manuscript for publication in a peer-reviewed journal. The paper was published in 2015. (2) Evaluation of the National Health and Nutrition Examination Survey (NHANES) data for associations between grapefruit or grapefruit juice consumption and health benefits. I assisted with the design of the analysis, evaluation and interpretation of results, and served as a co-author in the preparation of a manuscript for submission and publication in a peer-reviewed journal. The paper was published in 2014. This was the first published cross-sectional analysis of nationally representative data relating to grapefruit intake. (3) Preparation and submission of a commentary paper regarding 100% fruit juice and its place amid the current debate about the role of sugar in the diet. I served as sole author of the commentary. The paper was published in 2015. (4) I served as a co-presenter for a webinar concerning the health benefits associated with the consumption of citrus juices and other 100% fruit juices. The webinar was sponsored by the Produce for Better Health Foundation and approximately 200 nutrition or other health professionals participated by viewing the webinar. The information presented was intended to help practitioners and educators understand the newest research related to 100% fruit juice consumption and health benefits. The webinar was presented on May 8, 2014. (5) As part of an educational orange grove and processing plant tour activity conducted for registered dietitians, I presented a talk titled "100% Orange Juice: A Tour of the Science Related to Nutrition and Health Benefits". The information presented was intended to help registered dietitians/nutritionists understand the newest research related to 100% orange juice consumption so they can respond to consumer or media questions about 100% orange juice. The presentation was given on December 5, 2013. Objective 3: Evaluate and communicate associations between citrus juice consumption and health status or other indicators using longitudinally-collected data. Unfortunately, this goal had no major accomplishments. Work began on the project by successfully obtaining access to the longitudinal dataset (Coronary Artery Risk Development in Young Adults (CARDIA)) from the National Heart, Lung and Blood Institute of the National Institutes of Health. The data were downloaded and the analysis commenced. However, personnel and management changes put the project on hold for over a year and work has not been restarted as of the closure date of this project.

Progress 10/01/13 to 09/30/14
Outputs
Target Audience: Target audiences for accomplishments during this reporting period include health and nutrition professionals as well as consumers. Health and nutrition professionals were reached through several avenues, including the publication of three (3) research articles in peer-reviewed journals (see specific information under the "Products - Publications" section) as well as a webinar and presentation conducted for and attended by nutrition and health professionals, especially registered dietitians (see specific information under the "Other Products" section). Consumers were reached through media reporting of the findings of a research article publication titled "Knowledge, perceptions, and behaviors of adults concerning nonalcoholic beverages suggest some lack of comprehension related to sugars". Media coverage included a news release through the University of Florida's media department, local coverage (University of Florida radio and local TV station), other coverage in the state of Florida (Lakeland Ledger newspaper), as well as national coverage through a Reuter's news article that was picked up by various other media outlets. Changes/Problems: The primary problem encountered with this project has been with goal/objective #3 (evaluate and communicate associations between citrus juice consumption and health status or other indicators using longitudinally-collected data). The departure of two key personnel who were assisting with this analysis has put this activity on temporary hold. My goal is to assist with identifying new personnel to take over these roles and continue with the analysis as originally planned. What opportunities for training and professional development has the project provided?

How have the results been disseminated to communities of interest? Through media reporting of the scientific publication "Knowledge, perceptions, and behaviors of adults concerning nonalcoholic beverages suggest some lack of comprehension related to sugars", consumers were reached concerning the results of the study. Media coverage included a news release through the University of Florida's media department, local coverage (University of Florida radio and local TV station), other coverage in the state of Florida (Lakeland Ledger newspaper), as well as national coverage through a Reuter's news article that was picked up by various other media outlets. However, it is unknown how many consumers were reached through these efforts or their demographic characteristics as this research was not designed to capture or measure that information. Other findings from the review studies (see Goal/Objective 2) have been or are scheduled to be published in peer-reviewed scientific journals to be communicated to health professionals. Some of this information has been communicated to this group through webinars or other presentations (refer to "Other Programs" section). What do you plan to do during the next reporting period to accomplish the goals? Goal/Objective 1: Further investigate and report on consumer knowledge, perceptions, and behaviors with respect to the types of sugars in beverages. For all intents and purposes, this goal/objective has been reached with the publication of the study. No further activities are planned. Goal/Objective 2: Evaluate and communicate the associations between citrus juice consumption and health conditions and indicators through comprehensive review publications. The next phase of this goal/objective is to conduct a literature review concerning 100% citrus juice consumption and cardiovascular health markers/indicators. That work has begun and the plan for the next reporting period is to synthesize and evaluate the data, prepare a review article and submit a manuscript of findings to a peer-reviewed journal. Goal/Objective 3: Evaluate and communicate associations between citrus juice consumption and health status or other indicators using longitudinally-collected data. This is an on-going project that is currently on hold because of changes in personnel who were assisting with the statistical analysis of the longitudinal data. The goal is to resume the analysis and begin preparation of a manuscript for publication in a peer-reviewed journal.

What was accomplished under these goals?
Goal/Objective 1: Further investigate and report on consumer knowledge, perceptions, and behaviors with respect to the types of sugars in beverages. The major activities accomplished for this goal were the completion and publication of a study related to the results of a consumer survey about sugars in beverages. The published paper has been reported under the "Products" section. Although the publication was targeted to health professionals, local and national media coverage of the study allowed the results to be communicated directly to consumers. Goal/Objective 2: Evaluate and communicate the associations between citrus juice consumption and health conditions and indicators through comprehensive review publications. There were three (3) major activities accomplished for this goal. (1) A review article concerning the consumption of 100% citrus juices and their nutritional contribution, dietary benefits and association with anthropometric measures was submitted and accepted for publication by a peer-reviewed scientific journal. The article is "in press" and awaiting publication. (2) Submission, acceptance and publication of a cross-sectional study using the National Health and Nutrition Examination Survey (NHANES) data, that investigated the association between grapefruit consumption (fresh, canned, frozen, or 100% juice) and various health indicators, including nutrient intake, diet quality, and anthropometric measures. (3) Preparation and submission of a commentary paper titled "100% fruit juice: perspectives amid the sugar debate". This commentary has been submitted and is currently under review by the journal. Goal/Objective 3: Evaluate and communicate associations between citrus juice consumption and health status or other indicators using longitudinally-collected data. This is an on-going project that is currently on hold because of changes in personnel who were assisting with the statistical analysis of the longitudinal data. As such, there were no major accomplishments to report.

What opportunities for training and professional development has the project provided? Analysis of the longitudinal data (Goal/Objective 3) has provided an opportunity for research partners/professionals to expand their knowledge and skills related to the evaluation of a nutrition/health longitudinal dataset and statistical analysis of longitudinally collected health and dietary data. How have the results been disseminated to communities of interest?
Nothing Reported
What do you plan to do during the next reporting period to accomplish the goals? Goal/Objective 1: Further investigate and report on consumer knowledge, perceptions, and behaviors with respect to the types of sugars in beverages.Publish the data in a peer-reviewed journal and communicate the findings to stakeholders in the citrus industry(e.g., citrus growers, the Florida Department of Citrus, etc.), health professionals/educators, and the public.Communication may occur through press releases, website postings, trade publications, or other public relations or industry/consumer/health professionalcommunication materials. Goal/Objective 2:Evaluate and communicate the associations between citrus juice consumption and health conditions and indicators through comprehensive review publications. Publish the first review article related tocitrus juice and nutritional and dietary benefits as well as associations with anthropometric measures in children and adults. Develop a second review article that evalutes the published literature with respect to citrus juice intake and cardiovascular health markers (e.g., cholesterol,inflammatory markers, oxidative stress markers, endothelial function, etc.)and submit this manuscript to a peer-reviewed journal.As part of this objective, evaluate the utility of developing a third article concerning citrus juice intake and other metabolic biomarkers (e.g., related to glucose and insulin response, insulin resistance, metabolic syndrome, etc.) Goal/Objective 3: Evaluate and communicate associations between citrus juice consumption and health status or other indicators using longitudinally-collected data. Complete the analysis ofthe CARDIA data that examinesassociationsbetween citrus juice intake and anthropometric measures and present the findings at a scientific meeting. These results will also be published in a peer-reviewed journal. Begin a similar analysis with the same dataset regarding citrus juice intake and various cardiometabolic indicators/markers. .

What was accomplished under these goals?
Goal/Objective 1: Further investigate and report on consumer knowledge, perceptions, and behaviors with respect to the types of sugars in beverages.The major activities accomplishedfor this goal include working with a statistician to conduct and interpretthe statistical analysis of consumer survey data regarding sugars in beverages;the preparation and writing of a manuscript;and submission of the manuscriptto a professional peer-reviewed journal. At this time comments have been received from peer reviewers and the manuscript is being revised and resubmitted to the journal. Major findings suggest that many consumers are confused by or have limited knowledge of the types of sugars/sweeteners in beverages (e.g., natural, added, artificial sweeteners). Despite public health recommendations to limit the intake of added sugars, particularly sugar-sweetened beverages, many consumers do not have major concerns about the presence of added sugars in the beverages they consume. Goal/Objective 2:Evaluate and communicate the associations between citrus juice consumption and health conditions and indicators through comprehensive review publications. Published research related to citrus juice and nutritional and dietary benefits as well as associations with anthropometric measures in children and adults werereviewed, synthesized, and a comprehensive review manuscript has been prepared and submitted to a peer-reviewed journal. The consumption of citrus juicesis associated with better diet quality and nutrient adequacy in children and adults. Although the research is mixed, the majority of studies report no association between citrus juice (or 100% fruit juice) intake and various anthropometric measures in children and adults. However, the lack of clinical studies limits interpretation regarding cause and effect relationships. Goal/Objective 3: Evaluate and communicate associations between citrus juice consumption and health status or other indicators using longitudinally-collected data. Longitudinal data collected as part of the Coronary Artery Risk Development in Young Adults (CARDIA) cohort were obtained from the National Heart, Lung, and Blood Institute (NHLBI) of NIH. IRB approval to analyze the data was obtained from the University of Florida IRB-02. The data are currently being evaluated for associations between citrus juice intake and anthropometric measures and cardiometabolic outcomes/markers. These analyses are currently in progress and no results have been obtained at this time.
