Food companies' calorie-reduction pledges to improve U.S. diet.

ABSTRACT: Heretofore, corporate voluntary pledges to improve the health of Americans have been linked neither to explicit measurable commitments nor to a framework for an independent evaluation. The Healthy Weight Commitment Foundation (HWCF), whose members include 16 of the nation's leading consumer packaged goods food and beverage manufacturers, voluntarily pledged to collectively remove 1 trillion calories from their products by 2012 (against a 2007 baseline), and 1.5 trillion calories by 2015. The pledge is designed to reduce the calorie gap commensurate with the HWCF companies' role in the U.S. diet. To date, no system exists for documenting the nutritional and public health impacts of industry-led changes in the food supply on individual diets. The current study represents a unique opportunity to understand how the consumer packaged goods food and beverage sector is changing and how these changes are associated with changes in the American diet. It presents data on national caloric sales from this sector, purchases of these goods by various subpopulations, and methods linking these to individual intakes of Americans. Findings show that HWCF companies accounted for approximately 25% of calories consumed in the U.S. in 2007 and that the 1.5 trillion-calorie pledge (about 14 calories/day/capita) accounts for 0.8% of the calories sold across all consumer packaged goods food and beverage brands in 2007. The authors hope that this evaluation will continue to create models and methods for demonstrating the effects of changes in the food supply on individual diets, particularly among those from vulnerable subpopulations.

Project description:Background: Irritable Bowel Syndrome (IBS) is a widespread disease with variable symptoms that have an important impact on the quality of life. Despite the prevalence of IBS, its etiology and pathophysiology are still to be fully understood, but immune response is known to be involved. In this study, we investigated the variation of two specific cytokines, B-cell activating factor (BAFF) and platelet-activating factor (PAF), the levels of food-specific IgG and the symptom severity, using Irritable Bowel Syndrome-Symptom Severity Score (IBS-SSS), following a personalized and unrestricted-calorie diet.Methods: We enrolled 30 subjects with diagnosis of IBS, according to Rome-IV criteria, whose inflammatory markers were measured at baseline and after 6 weeks of dietary intervention. The subjects were monitored in a general practice outpatient setting and nutritional advice was offered remotely via two telephone sessions with a nutritionist.Results: BAFF and PAF values did not differ between baseline and end of study, both in compliant (C) and non-compliant (NC) subjects. IgG levels significantly decreased only in compliant subjects: 37.32 (23.24-93.67) IU/mL; 27.9 (7.56-93.96) IU/mL (p?=?0.02) and in non-compliant went from 51.83 (13.17-113.1) IU/mL to 44.06 (4.96-255.4) IU/mL (p?=?0.97, ns). IBS-SSS significantly decreased in both compliant subjects, from 245 (110-480) to 110 (0-140) (p?<?0.0001), and non compliant subjects, from 250 (155-370) to 100 (7-220) (p?<?0.0001). Comparing IBS-SSS between week 3 and week 6, only compliant subjects had a significant reduction, from 155 (50-355) to 110 (0-140) (p?=?0.005), versus non-compliant, from 115 (35-315) to 100 (7-220) (p?=?0.33, ns).Conclusion: These findings support the rapid efficacy and suitability of a personalized dietetic intervention with outside consultation in IBS.Trial registration: ClinicalTrials.gov ID NCT04348760 Registered April 15, 2020 (retrospectively registered) https://clinicaltrials.gov/show/NCT04348760.

Project description:BackgroundRecent studies show corporate political activity (CPA) can have detrimental impacts on health policy processes. The Control of Marketing Promotion of Infant and Young Child Food Act B.E. 2560 (the Act) was implemented in Thailand in 2017, but there have been no studies documenting CPA during its policy processes. Furthermore, the effects of CPA on the Act and how non-industry stakeholders dealt with the CPA have not been explored. This study aimed to analyze the CPA of baby food companies in Thailand, its effects on the Act, and how policymakers have responded to CPA around the Act.MethodsThis qualitative study applied an established framework developed by Mialon and colleagues to collect and systematically analyze publicly available information from seven baby food companies with the highest percentage market share in Thailand. In-depth interviews were also used to explore how people involved in the policy process of the Act experienced the CPA of baby food companies, the consequent effects on the Act, and how they responded to the CPA.ResultsDuring development of the Act, baby food companies used two main strategies, 'information and messaging' and 'constituency building'. We found the companies met policymakers, and they employed evidence or provided information that was favorable to companies. Also, they established relationships with policymakers, health organizations, communities and media. The effects of CPA were that the scope of products controlled by the Act was reduced, and CPA led relevant people to misunderstand and have concerns about the Act. Officials and others countered the influence of CPA by raising awareness and building understanding among involved people, as well as avoiding contact with companies informally.ConclusionsCPA consists of a variety of practices that resulted in a weakened Act in Thailand. Government officials and other non-industry stakeholders employed strategies to counteract this influence. This study suggests the Department of Health, and other relevant government agencies, would benefit from establishing safeguards and protections against CPA. Efforts to raise awareness about the harms of CPA within and outside of government and establish a systematic monitoring system, including avoid conflict of interest in policy process would improve policymaking and implementation of the Act.

Project description:BACKGROUND:Software designed to accurately estimate food calories from still images could help users and health professionals identify dietary patterns and food choices associated with health and health risks more effectively. However, calorie estimation from images is difficult, and no publicly available software can do so accurately while minimizing the burden associated with data collection and analysis. OBJECTIVE:The aim of this study was to determine the accuracy of crowdsourced annotations of calorie content in food images and to identify and quantify sources of bias and noise as a function of respondent characteristics and food qualities (eg, energy density). METHODS:We invited adult social media users to provide calorie estimates for 20 food images (for which ground truth calorie data were known) using a custom-built webpage that administers an online quiz. The images were selected to provide a range of food types and energy density. Participants optionally provided age range, gender, and their height and weight. In addition, 5 nutrition experts provided annotations for the same data to form a basis of comparison. We examined estimated accuracy on the basis of expertise, demographic data, and food qualities using linear mixed-effects models with participant and image index as random variables. We also analyzed the advantage of aggregating nonexpert estimates. RESULTS:A total of 2028 respondents agreed to participate in the study (males: 770/2028, 37.97%, mean body mass index: 27.5 kg/m2). Average accuracy was 5 out of 20 correct guesses, where "correct" was defined as a number within 20% of the ground truth. Even a small crowd of 10 individuals achieved an accuracy of 7, exceeding the average individual and expert annotator's accuracy of 5. Women were more accurate than men (P<.001), and younger people were more accurate than older people (P<.001). The calorie content of energy-dense foods was overestimated (P=.02). Participants performed worse when images contained reference objects, such as credit cards, for scale (P=.01). CONCLUSIONS:Our findings provide new information about how calories are estimated from food images, which can inform the design of related software and analyses.
