Abstract Objectives Red and processed meats are associated with cardiometabolic disease (CMD) risk; yet, corresponding global burdens are not well established. We aimed to quantify the impact of meat intake on coronary heart disease (CHD) and type 2 diabetes mortality by nation (n = 187), super-region (n = 9), age (20 + y), and sex using the largest standardized Global Dietary Database (GDD) available. Methods A comparative risk assessment model estimated the absolute and % CHD and diabetes mortality attributable to suboptimal unprocessed red and processed meat consumption, incorporating data and corresponding uncertainty on: intakes from the GDD, estimated by a Bayesian hierarchical imputation model using national and sub-national surveys worldwide (266 surveys; 1630,069 individuals; 113/187 countries; 82% of the world's population); etiologic effects of meat intake on CHD and diabetes mortality from meta-analyses of prospective cohorts; optimal population meat intakes based on observed intakes associated with lowest risk; and disease-specific deaths from the Global Burden of Diseases. Results In 2010, suboptimal red meat intake was associated with 43,987 (95% uncertainty interval: 42,243–45,635) diabetes deaths, accounting for 3.5% (3.4–3.6%) of global diabetes mortality. Highest proportional mortality was estimated in Central African Republic, United Arab Emirates, and Gabon (Figure 1). Similar attributable mortality was seen in men (4%) vs women (3%), and higher in younger (25–54 y; 5–7%) vs older (55–85 y; 1–4%) adults. Processed meat intake was linked to 510,214 (482,092–541,175) CHD and 86,923 (83,832–90,488) diabetes deaths, accounting for 7.3% (6.9–7.8%) of global CHD and 6.9% (6.7–7.2%) of diabetes mortality. CHD mortality was highest in Panama, Costa Rica, and Colombia, and diabetes mortality in Panama, Belarus, and El Salvador (Figure 2). Attributable mortality was higher in men vs women (CHD: 9 vs 6%; diabetes: 8 vs 6%), and in younger vs older adults (14–15% vs 4–11%; 12–15% vs 3–9%). Meat-related CMD burdens in 1990 and 2015 will be presented at the meeting. Conclusions Suboptimal processed meat intake contributed to substantial CMD mortality, greatly exceeding burdens attributed to unprocessed red meats. Such data highlight the need for strategies to reduce meat, particularly processed meat, consumption. Funding Sources Gates Foundation. Supporting Tables, Images and/or Graphs

AbstractObjectiveTo evaluate red and processed meat intake, and the impact meat consumption has on diet quality and the environment.DesignA large cross-sectional health survey performed in São Paulo, Brazil.SettingDiet was assessed by two 24 h dietary recalls. Usual intakes were calculated using the Multiple Source Method. The World Cancer Research Fund recommendation of an average of 71·4 g/d was used as the cut-off point to estimate excessive red and processed meat consumption. To investigate the relationship between meat consumption and diet quality we used the Brazilian Healthy Eating Index Revised. The environmental impact was analysed according to estimates of CO2 equivalent emissions from meat consumption.SubjectsBrazilians (n 1677) aged 19 years and older were studied.ResultsThe mean red and processed meat intake was 138 g/d for men and 81 g/d for women. About 81 % of men and 58 % of women consumed more meat than recommended. Diet quality was inversely associated with excessive meat intake in men. In Brazil alone, greenhouse gas emissions from meat consumption, in 2003, were estimated at approximately 18 071 988 tonnes of CO2 equivalents, representing about 4 % of the total CO2 emitted by agriculture.ConclusionsThe excessive meat intake, associated with poorer diet quality observed, support initiatives and policies advising to reduce red and processed meat intake to within the recommended amounts, as part of a healthy and environmentally sustainable diet.

Introduction: Over the last decade, the possible impact of meat intake on overall cancer incidence and mortality has received considerable attention, and authorities have recommended decreasing consumption; however, the benefits of reducing meat consumption are small and uncertain. As such, individual decisions to reduce consumption are value- and preference-sensitive. Consequently, we undertook a pilot cross-sectional study to explore people’s values and preferences towards meat consumption in the face of cancer risk. Methods and analysis: The mixed-method pilot study included a quantitative questionnaire followed by qualitative evaluation to explore the dietary habits of 32 meat eaters, their reasons for eating meat, and willingness to change their meat consumption when faced with a potential risk reduction of cancer over a lifetime based on a systematic review and dose–response meta-analysis. We recruited a convenience sample of participants from two Canadian provinces: Nova Scotia and Prince Edward Island. This project was approved by the Research Ethics Board for Health Sciences research at Dalhousie University, Canada. Results: The average weekly consumption of red meat was 3.4 servings and the average weekly consumption of processed meat was 3 servings. The determinants that influenced meat intake were similar for both red and processed meat. Taste, cost, and family preferences were the three most commonly cited factors impacting red meat intake. Taste, cost, and (lack of) cooking time were the three most commonly cited factors impacting processed meat intake. None of the participants were willing to eliminate red or processed meat from their diet. About half of participants were willing to potentially reduce their meat consumption, with one third definitely willing to reduce their consumption. Strengths and limitations: This study is the first that we are aware of to share data with participants on the association of red meat and processed meat consumption and the risk of cancer mortality and cancer incidence, including the certainty of evidence for the risk reduction. The limitations of this study include its small sample size and its limited geographic sampling. Conclusions: When presented explicit information about the small uncertain cancer risk associated with red and processed meat consumption, study participants were unwilling to eliminate meat, while about one-third were willing to reduce their meat intake.

Purpose Red and processed meat intake is convincingly associated with colorectal cancer (CRC) incidence, but its impact on prognosis after CRC diagnosis is unknown. We examined associations of red and processed meat consumption, self-reported before and after cancer diagnosis, with all-cause and cause-specific mortality among men and women with invasive, nonmetastatic CRC. Patients and Methods Participants in the Cancer Prevention Study II Nutrition Cohort reported information on diet and other factors at baseline in 1992-1993, 1999, and 2003. Participants with a verified CRC diagnosis after baseline and up to June 30, 2009, were observed for mortality through December 31, 2010. Results Among 2,315 participants diagnosed with CRC, 966 died during follow-up (413 from CRC and 176 from cardiovascular disease [CVD]). In multivariable-adjusted Cox proportional hazards regression models, red and processed meat intake before CRC diagnosis was associated with higher risks of death as a result of all causes (top v bottom quartile, relative risk [RR], 1.29; 95% CI, 1.05 to 1.59; Ptrend = .03) and from CVD (RR, 1.63; 95% CI, 1.00 to 2.67; Ptrend = .08) but not CRC (RR, 1.09; 95% CI, 0.79 to 1.51; Ptrend = 0.54). Although red and processed meat consumption after CRC diagnosis was not associated with mortality, survivors with consistently high (median or higher) intakes before and after diagnosis had a higher risk of CRC-specific mortality (RR, 1.79; 95% CI, 1.11 to 2.89) compared with those with consistently low intakes. Conclusion This study suggests that greater red and processed meat intake before diagnosis is associated with higher risk of death among patients with nonmetastatic CRC.

Background Multiple epidemiological studies link greater red and processed meat consumption with poorer cardiovascular outcomes. However, the impact of these exposures on directly measured cardiovascular phenotypes has not been examined in large cohorts. Limited existing studies suggest that the observed associations may be mediated by cardiometabolic diseases and/or novel mechanisms acting via the heart-gut axes. However, few studies systematically examine potential confounding and mediating mechanisms. Purpose We assessed, in the UK Biobank, the association between meat intake and cardiovascular structure and function incorporating a comprehensive range of confounders and mediators. Methods We studied 19,408 participants with cardiovascular magnetic resonance (CMR) data. We determined average daily red and processed meat intake using food frequency questionnaires. We used oily fish as a comparator linked to favourable cardiac health. We considered conventional CMR measures (ventricular volumes, left ventricular mass, ejection fraction, stroke volume), novel CMR radiomics features (shape, texture), and arterial stiffness metrics (arterial stiffness index, aortic distensibility). Multivariable linear regression models were used to investigate associations between meat/fish intake and cardiovascular phenotypes, adjusting for age, sex, deprivation, educational level, smoking, alcohol intake, and exercise. In separate models, we investigated the mediating role of cardiometabolic morbidities. Results Higher intake of red and processed meat was associated with an adverse overall pattern of right and left ventricular remodelling, poorer cardiac function, and higher arterial stiffness. Conversely, higher oily fish intake was associated with a healthy cardiovascular phenotype (better ventricular function, greater arterial compliance). Radiomics analysis showed association of the different dietary habits with unique overall geometry of the ventricles and myocardial texture. These associations were partially mediated by cardiometabolic morbidities. Conclusions Higher red and processed meat consumption is associated with adverse cardiovascular phenotypes. These relationships are not fully explained by mediation through cardiometabolic morbidities suggesting importance of alternative disease pathways. Understanding these potential novel disease mechanisms is important for optimising cardiovascular disease prevention strategies.

AbstractObjectiveTo examine and quantify the potential dose–response relationship between red and processed meat consumption and risk of all-cause, cardiovascular and cancer mortality.DesignWe searched MEDLINE, Embase, ISI Web of Knowledge, CINHAL, Scopus, the Cochrane library and reference lists of retrieved articles up to 30 November 2014 without language restrictions. We retrieved prospective cohort studies that reported risk estimates for all-cause, cardiovascular and cancer mortality by red and/or processed meat intake levels. The dose–response relationships were estimated using data from red and processed meat intake categories in each study. Random-effects models were used to calculate pooled relative risks and 95 % confidence intervals and to incorporate between-study variations.ResultsNine articles with seventeen prospective cohorts were eligible in this meta-analysis, including a total of 150 328 deaths. There was evidence of a non-linear association between processed meat consumption and risk of all-cause and cardiovascular mortality, but not for cancer mortality. For processed meat, the pooled relative risk with an increase of one serving per day was 1·15 (95 % CI 1·11, 1·19) for all-cause mortality (five studies; P<0·001 for linear trend), 1·15 (95 % CI 1·07, 1·24) for cardiovascular mortality (six studies; P<0·001) and 1·08 (95 % CI 1·06, 1·11) for cancer mortality (five studies; P<0·001). Similar associations were found with total meat intake. The association between unprocessed red meat consumption and mortality risk was found in the US populations, but not in European or Asian populations.ConclusionsThe present meta-analysis indicates that higher consumption of total red meat and processed meat is associated with an increased risk of total, cardiovascular and cancer mortality.

Close economic ties encourage production and trade of meat between Canada, Mexico, and the US. Understanding the patterns of red and processed meat consumption in North America may inform policies designed to reduce meat consumption and bolster environmental and public health efforts across the continent. We used nationally-representative cross-sectional survey data to analyze consumption of unprocessed red meat; processed meat; and total red and processed meat. Generalized linear models were used to separately estimate probability of consumption and adjusted mean intake. Prevalence of total meat consumers was higher in the US (73.6, 95% CI: 72.3–74.8%) than in Canada (65.6, 63.9–67.2%) or Mexico (62.7, 58.1–67.2%). Men were more likely to consume unprocessed red, processed, and total meat, and had larger estimated intakes. In Mexico, high wealth individuals were more likely to consume all three categories of meat. In the US and Canada, those with high education were less likely to consume total and processed meat. Estimated mean intake of unprocessed red, processed, and total meat did not differ across sociodemographic strata. Overall consumption of red and processed meat remains high in North America. Policies to reduce meat consumption are appropriate for all three countries.
