ABSTRACT
Objectives: To conduct a scoping review to map available evidence about the health impact of gut microbiota-derived metabolites in humans.
Methods: We searched PubMed and Embase for studies that assessed the health impact of gut microbiota-derived metabolites in humans. We included case-control studies, cross-sectional studies, cohort studies, and clinical trials. Any health condition was considered. Based on an initial prioritization phase informed by preliminary searching and expert input, we narrowed our scope to ten metabolites: deoxycholate or deoxycholic acid (DCA), lithocholate or lithocholic acid (LCA), glycolithocholate or glycolithocholic acid, glycodeoxycholate or glycodeoxycholic acid, tryptamine, putrescine, d-alanine, urolithins, N-acetylmannosamine, and phenylacetylglutamine. We used evidence mapping to identify evidence gaps and associations that may permit future systematic reviews. The screening was conducted in PICO Portal aided by artificial intelligence.
Results: Overall, for these 10 metabolites, we identified 352 studies with 168,072 participants. Most (326, 92.6%) were case-control studies, followed by cohort studies (14, 4.0%), clinical trials (8, 2.3%), and cross-sectional studies (6, 1.7%). Most studies assessed the following associations: DCA on hepatobiliary disorders (64 studies, 7,976 participants), colorectal cancer (19 studies, 7,461 participants), and other digestive disorders (27 studies, 2,463 participants); LCA on hepatobiliary disorders (34 studies, 4,297 participants), colorectal cancers (14 studies, 4,955 participants), and other digestive disorders (26 studies, 2,117 participants); putrescine on colorectal cancers (16 studies, 94,399 participants) and cancers excluding colorectal and hepatobiliary cancers (42 studies, 4,250 participants).
Conclusions: The association of gut microbiota-derived metabolites and human health is being examined in an increasing number of studies, most of which are case-control studies. As these metabolites hold considerable potential for elucidating microbiome-disease associations, there is a need to conduct more prospective studies including clinical trials. Moreover, systemic reviews are needed to characterize the metabolite-disease associations.

Topical Area: Dietary Patterns
Supported by: IAFNS Carbohydrates and Low- and No-Calorie Sweeteners Committees

ABSTRACT
Objectives: An evidence map was conducted to characterize published research investigating dietary sweetness and body weight. The primary aim was to identify studies that investigate total dietary sweetness and body weight-related outcomes among healthy adults; the secondary aim was to map the evidence that investigates sugar, sweetener, or sweet food/beverage intake and body weight.
Methods: Using pre-registered search terms (https://osf.io/my7pb), 33,609 publications (duplicates removed) from PubMed, Cochrane Library, and Scopus were screened for inclusion. Eligible studies were cross-sectional studies, longitudinal cohort studies, case control studies, clinical trials, and systematic reviews conducted among adults (≥18 years) which investigated the associations between total dietary sweetness, sugar, sweetener (energetic or nonenergetic), or sweet food/beverage intake on body weight, body mass index, adiposity, and energy intake.
Results: A total of 824 eligible publications were identified. Two clinical trials and 5 cross-sectional studies investigated the associations between total dietary sweetness and a body weight-related outcome. An additional 630 publications were identified that investigated sugar, sweetener, or sweet food/beverage intake and body weight-related outcomes, including 225 clinical trials, 87 longitudinal cohort studies, and 298 cross-sectional studies. Ninety publications reported on dietary patterns that included sweet foods/beverages alongside other dietary components. Most studies (91%) did not measure the sweetness of the diet or individual foods consumed. Additionally, 97 systematic reviews that addressed relevant but different research questions related to sweetness exposure and body weight-related outcomes were identified.
Conclusions: While there is a breadth of evidence available from studies that investigate sugar, sweetener, and sweet food/beverage intake and body weight, there is limited evidence on the association between total dietary sweetness exposure and body weight.

Quality of Popular Diets in the United States: Abstract Presentation Number: PO08-09-22
Expand
Presenting Author: Zach Conrad, William & Mary
Topical Area: Dietary Patterns
Supported by: IAFNS Carbohydrates Committee
For more information, see here.
ABSTRACT
Objectives: 1) Evaluate the quality of popular diets in the US, and 2) model the effect of targeted food substitutions on diet quality.
Methods: Dietary data from 34,411 adults ≥20 y were acquired from the National Health and Nutrition Examination Survey, 2005-2018. Usual dietary intake was assessed using the National Cancer Institute's usual intake methodology, and the Healthy Eating Index-2015 was used to evaluate the diet quality of eleven popular diets. A diet model was used to evaluate the effect of targeted food substitutions on diet quality.
Results: Participants that followed a pescatarian diet pattern had the highest diet quality (65.2, 95% CI: 64.0-66.4), followed by vegetarian (63.0, 62.0-63.0), very low grain (62.7, 62.2-63.3), flexible paleo (62.3, 61.1-63.4), low grain (61.2, 60.6-61.9), low-moderate grain (59.7, 59.3-60.2), omnivorous (57.8, 57.5-58.1), restricted carbohydrate (56.9, 56.6-57.3), time restricted (55.2, 54.8-55.5), moderate protein (55.0, 54.7-55.3), and high protein (51.8, 51.0-62.7). Modeled replacement of up to three daily servings of foods highest in added sugar, sodium, and saturated fat with alternative foods led to a statistically significant increase in diet quality and a decrease in energy intake for most diets (P < 0.001 for most diets).
Conclusions: Low diet quality was observed for all popular diets evaluated in this study. Modeled dietary shifts that align with recommendations to choose foods lower in added sugar, sodium, and saturated fat led to only modest improvements in diet quality but a larger reduction in energy intake. Greater efforts are needed to shift consumer perceptions away from reductionist dietary approaches that place undue emphasis on specific foods, individual macronutrients, and timing of eating, and toward healthy dietary patterns that emphasize consumption of a variety of high-quality food groups.

ABSTRACT
Objectives: This study evaluated the association between restricted carbohydrate diets and prevalent cardiometabolic disease (CMD), stratified by fat intake.
Methods: Dietary and CMD data were obtained from 19,078 participants ≥20 y in the National Health and Nutrition Examination Survey (NHANES) 1999-2018. The National Cancer Institute (NCI) methodology was used to assess usual intake of foods and nutrients.
Results: Compared to individuals that met all macronutrient recommendations, those consuming restricted carbohydrate diets ( < 45%en) were 1.123 (95% CI 1.113-1.133) times as likely to have CMD, and those consuming the recommended amount of carbohydrates only were 1.060 (1.058-1.062) times as likely to have CMD. Higher intakes of saturated and polyunsaturated fat were associated with greater prevalence of CMD in restricted and recommended carbohydrate intake groups. Higher intakes of monounsaturated fat were associated with lower prevalence of CMD among participants that met carbohydrate recommendations only.
Conclusions: Participants that consumed restricted carbohydrate diets were more likely to have CMD compared to participants that met all macronutrient recommendations, and this association was modified by fat intake. Greater efforts are needed to understand longitudinal associations between carbohydrate intake and CMD.

ABSTRACT
Objectives: This study evaluated the association between a restricted carbohydrate diet ( < 45% energy from carbohydrate) and metabolic syndrome stratified by fatty acid classes in a nationally representative sample of U.S adults.
Methods: Data on food and nutrient intake, and markers of metabolic syndrome, were obtained from 19,078 respondents ≥20 y in the National Health and Nutrition Examination Survey (NHANES) 1999-2018. The National Cancer Institute's usual intake methodology was used to evaluate the associations between usual dietary intake and prevalent metabolic syndrome.
Results: Compared to individuals that met all AMDR macronutrient recommendations, the odds of having metabolic syndrome were 1.085 (95%CI: 1.077-1.094) times higher among those that consumed a restricted carbohydrate diet (P < 0.001) and 1.115 (1.153-1.156) times higher for those that met only current recommendations for total carbohydrates (P < 0.001). Higher fat intake, regardless of class, was associated with increased likelihood of metabolic syndrome among individuals that consumed restricted carbohydrate diets but not among individuals that met current carbohydrate recommendations.
Conclusions: The likelihood of prevalent metabolic syndrome was moderately higher (8.5%) among individuals that consumed restricted carbohydrate diets compared to individuals that met all macronutrient recommendations. High intake of fat of any class was associated with increased likelihood of metabolic syndrome in those consuming a restricted carbohydrate diet.

ABSTRACT:
Objectives: Little is known about the relationships between habitual essential amino acid (EAA) intake and functional health in older US adults. This cross-sectional study investigates associations between usual EAA intakes and body composition, muscle strength, and physical function in US adults ≥ 65 y.
Methods: The Food and Nutrient Database for Dietary Studies (FNDDS) 2001-2018 was linked to USDA FoodData Central to access existing EAA composition data for FNDDS ingredients. FNDDS ingredients without existing EAA data were matched to similar ingredient codes with available EAA data. Usual intakes of EAA, leucine, lysine, and sulfur-containing AAs (SAA; methionine + cysteine) from NHANES 2001-2018 were calculated as relative [mg/kg ideal body weight (IBW)/d] and absolute (g/d) intakes for individuals ≥ 65 y (n=10,843). Dependent variables were muscle strength measured by isometric grip test, BMI, waist circumference (WC), DXA-measured appendicular lean mass and whole-body fat mass, and self-reported physical function. Regression analyses were used to determine covariate-adjusted relationships between EAA, leucine, lysine, and SAA intake and functional health outcomes. P < 0.0013 was considered significant.
Results: Absolute and relative EAA, leucine, lysine, and SAA intakes were not associated with muscle strength or self-reported physical function in males or females or with body composition in males. Absolute EAA intakes (per g) were associated with WC in females (β ± SEM, 2.1 ± 0.6 cm, P = 0.0007). Absolute lysine intakes (per g) were associated with BMI (3.0 ± 0.7 kg/m2, P < 0.0001) and WC (7.0 ± 1.7 cm, P = 0.0001) in females. Relative EAA, leucine, and lysine intakes (per mg/kg IBW) were associated with BMI (0.07 ± 0.02, 0.26 ± 0.07, and 0.25 ± 0.04 kg/m2, respectively; P ≤ 0.0004 for all) and WC (0.18 ± 0.03, 0.81 ± 0.17, and 0.64 ± 0.10 cm, respectively; P < 0.0001 for all) in females. Relative lysine intakes (per mg/kg IBW) were associated with whole body fat mass (0.24 ± 0.07 kg, P = 0.0006) in females.
Conclusions: EAA intakes, particularly lysine, were positively associated with measures of adiposity in women ≥ 65 y. Investigating sources of lysine intake may provide insight about which foods or food groups are driving this relationship.

ABSTRACT
Objectives: The lack of complete amino acid composition data in food composition databases has made determining population-wide amino acid intake difficult. This cross-sectional study characterizes habitual intakes of each amino acid and adherence to dietary requirements for each essential amino acid (EAA) by age, gender, and race/ethnicity in the US population.
Methods: Food and Nutrient Database for Dietary Studies ingredient codes with missing amino acid composition data were matched to similar ingredients with available data, so that amino acid composition could be determined for virtually 100% of foods reported in What We Eat in America, the dietary intake assessment component of NHANES. Amino acid intakes during 2-y cycles of NHANES 2001-2018 (n = 84,629; ≥ 2y) were calculated as relative [mg/kg of ideal body weight (IBW)/d] and absolute (g/d) intakes. Data from NHANES 2011-2018 were used to determine the percentage of the population consuming less than the Dietary Reference Intakes for each EAA by age, sex, and race/ethnicity.
Results: Relative intakes of EAAs were greatest in those 2-3 y (females: 1552 ± 9 and males: 1659 ± 9 mg/kg IBW/d) and lowest in those ≥ 80 y (females: 446 ± 2 and males: 461 ± 3 mg/kg IBW/d). Absolute intakes of EAAs were greatest in those 31-50 y (females: 31.4 ± 0.1 and males: 45.5 ± 0.1 g/d) and lowest in those 2-3 y (females: 22.4 ± 0.1 and males: 26.0 ± 0.1 g/d). In individuals 2-18 y and ≥ 19 y, relative intakes of EAAs were lowest in the NHB population (860 ± 16 and 505 ± 5 mg/kg IBW/d, respectively) and highest in the Asian population (994 ± 35 and 580 ± 7 mg/kg IBW/d, respectively). Less than 1% of individuals ≥ 19 y were not meeting the Estimated Average Requirements for each EAA.
Conclusions: Individual amino acid intakes in the US population exceed recommended minimum population requirements. Future studies can use the method described here to quantify habitual amino acid intake and examine relationships with health and disease.

Each year, the International Association for Food Protection hosts an Annual Meeting, providing attendees with information on current and emerging food safety issues, the latest science, innovative solutions to new and recurring problems, and the opportunity to network with thousands of food safety professionals from around the globe.
IAFNS is supporting three sessions, a roundtable event and three posters at the 2019 IAFP Annual Meeting.
Scientific Sessions:
Managing Large Multidisciplinary/Multi-Institutional Food Safety Projects - Effectively, Impactfully, and with Integrity
Expand
Monday, July 22, 2019 | 1:30 - 5:15 PM | Ballroom D
Food safety is a complex and multidisciplinary challenge. Therefore, federally-funded food safety projects, and even industry-centered projects, increasingly involve large, multidisciplinary/multiinstitutional collaborative teams. However, very few individuals thrust into these roles have formal education or training in managing such projects. This symposium brings together a unique and diverse cohort of presenters, ranging from an expert on assessing the effectiveness and impact of research collaborations and centers (with experience on multiple food safety project teams) to experienced managers of such projects (in government, academic, and industry) to a representative of the Scientific Integrity Consortium. The speakers will describe measures for evaluating the effectiveness of such largescale collaborations, identify common features of successful collaborations, share best practices for forming and managing such teams, and outline essential foundational principles for ensuring the quality and integrity of the resulting research. A panel discussion is included to maximize opportunities for attendee interaction with the multiple perspectives provided by the speakers. After this session, attendees will have a better appreciation on how to play together well in the research sandbox.

The Mitigation and Regulation of Heat-Formed Substances Produced in Foods During Cooking: What are the Unintended Consequences on Microbial Safety and Public Health?
Expand
Tuesday, July 23, 2019 | 10:45 AM - 12:15 PM | M107
A growing field in food safety is the focus on the potential risk of heat-formed substances produced during cooking. Compounds that are known as human health hazards are being increasingly identified as heat-formed substances present in food. Two prominent examples of this are acrylamide and furfuryl alcohol, both of which are present in significant amounts in a wide array of foods. This session will help inform how the risk assessment process of heat-formed substances can incorporate the benefits of cooking and cooked food. It will highlight the genetic changes that allowed humans to consume cooked food. The session will then explore the unintended consequences in mitigating heat formed substances, such as introducing microbial hazards. It will address how to assess and communicate these risks to food processors and consumers. The potential impact and implications on the food industry and, ultimately, the end consumer, of using current approaches to assess the potential public health impact of compounds formed during routine cooking of food will be debated.

Let's Hear from Next Generation Food Safety Scientists on Pathogen Behavior in Ready to Eat Foods
Expand
Wednesday, July 24, 2019 | 1:30 - 3:30 PM | Ballroom E
A current research collaboration between Health Canada, the University of Guelph and North Carolina State University is investigating the survival and inactivation of Listeria monocytogenes, Salmonella, and foodborne viruses during the storage of low moisture foods. This is a wide-ranging research consortium funded by the IAFNS Food Microbiology Committee and includes a number of developing research scientists who will also present their findings. The IAFNS Food Microbiology Committee is committed to proactively improving the understanding and control of microbial food safety hazards to enable scientifically informed decision making. The Committee achieves its mission by funding research that is conducted at institutions who also train the next generation of food safety scientists.
Ready-to-eat low moisture products such as nuts, dried fruits, cereal products, and chocolate are often ingredients used in the manufacturing of many food products. They carry significant potential for the amplification of outbreaks and recalls over a wide variety of products. The research consortium represented by this next generation of food safety experts is studying several aspects of pathogen behavior in low moisture ready-to-eat foods and goes beyond traditional thermal mitigation strategies.
Conveners: Laurie Post, PhD, Deibel Labs; Edith Wilkin, PhD, Leprino Foods
Survival, Inactivation and Detection of Foodborne Viruses During Long Term Storage in Chocolate, Pistachios and Cornflakes
Neda Nasheri, PhD, Health Canada

Roundtable Event:
Is It Time for Food Safety Performance Standards Since Zero Risk Is Not an Option?
Expand
Monday, July 22, 2019 | 10:45 AM - 12:15 PM | Ballroom E
Food safety systems rely on verification activities to determine if the system is working as designed and validated. Microbiological performance standards can be used to verify if a processing system is adequately controlling a specific hazard. Performance standards should be set to protect public health. Sampling protocols and microbiological testing methods must be appropriate for the food being tested. In the US poultry industry, performance standards have been in place to measure the prevalence of Salmonella. Over time, the performance standards have changed to reflect the improved conditions in the industry. Prevalence based performance standards may work for other product categories, especially in dry products of raw agricultural products such as wheat flours and the produce area especially for frozen fruits and vegetables. This roundtable discussion will explore the current and potential future uses of performance standards in foods where it is not reasonable to expect zero presence of pathogens.
