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.

AbstractBackgroundRed and processed meat has been consistently associated with risk for colorectal cancer, but evidence for other cancer sites is limited and few studies have examined the association between poultry intake and cancer risk. We examined associations between total meat, red meat, processed meat and poultry intake and incidence for 20 common cancer sites.Methods and FindingsWe analysed data from 475,023 participants (54% women) in UK Biobank. Participants were aged 37-73 years and cancer free at baseline. Information on meat consumption was based on a touchscreen questionnaire completed at baseline covering type and frequency of meat intake. Diet intake was re-measured a minimum of three times in a subsample (15%) using a web-based 24h dietary recall questionnaire. Multivariable-adjusted Cox proportional hazards models were used to determine the association between baseline meat intake and cancer incidence. Trends in risk across baseline meat intake categories were calculated by assigning a mean value to each category using estimates from the re-measured meat intakes. During a mean follow-up of 6.9 years, 28,955 participants were diagnosed with a malignant cancer. Total, red and processed meat intakes were each positively associated with risk of colorectal cancer (e.g. hazard ratio (HR) per 70 g/day higher intake of red and processed meat combined 1.31, 95%-confidence interval (CI) 1.14-1.52).Red meat intake was positively associated with breast cancer (HR per 50 g/day higher intake 1.12, 1.01-1.24) and prostate cancer (1.15, 1.03-1.29). Poultry intake was positively associated with risk for cancers of the lymphatic and hematopoietic tissues (HR per 30g/day higher intake 1.16, 1.03-1.32). Only the associations with colorectal cancer were robust to Bonferroni correction for multiple comparisons. Study limitations include unrepresentativeness of the study sample for the UK population, low case numbers for less common cancers and the possibility of residual confounding.ConclusionsHigher intakes of red and processed meat were associated with a higher risk of colorectal cancer. The observed positive associations of red meat consumption with breast and prostate cancer, and poultry intake with cancers of the lymphatic and hematopoietic tissues, require further investigation.

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

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.

AbstractIntroductionMeat intake is thought to play a role in the risk of cancer. The Third Expert Report of the World Cancer Research Fund/American Institute for Cancer Research concluded that red meat was a probable cause and processed meat a convincing cause of colorectal cancer. However, evidence for associations between red and processed meat intake and other cancer sites is limited. Furthermore, few studies have investigated the association between poultry intake and cancer risk. Therefore, this study aimed to examine the associations between red, processed meat and poultry intake and incidence for 20 common cancer sites.Material and methodsWe analysed data from 475,264 participants (54 % women) in UK Biobank. Participants were aged 37–73 years and cancer free at baseline. Cancer diagnosis and death due to cancer without prior diagnosis during follow-up were determined using data-linkage with cancer and death registries (with follow-up until 31 March 2016 for England and Wales and until 31 October 2015 for Scotland, respectively). Information on meat consumption was based on a touchscreen questionnaire completed at baseline covering type and frequency of meat intake. We used multivariable-adjusted Cox proportional hazards models to determine the association between baseline meat intake and cancer incidence. Analyses of lung cancer risk were restricted to never smokers. All analyses were adjusted for socio-demographic, lifestyle and women-specific factors.ResultsOver a mean 6.9 (SD 1.3) years of follow-up, 28,431 participants were diagnosed with any type of cancer. Red meat intake was positively associated with risk for colorectal cancer (n cases = 3,164; Hazard ratio (HR) per 50 g/day higher intake 1.22, 95% Confidence Interval (CI) 1.05–1.41), breast cancer (n cases = 5,536; 1.12, 1.01–1.24) and prostate cancer (n cases = 5,807; 1.16, 1.03–1.30). Processed meat intake was positively associated with risk for colorectal cancer (n cases = 3,189; HR per 20 g/day higher intake 1.17, 95% CI 1.06–1.30). Poultry intake was positively associated with risk for cancers of the lymphatic and hematopoietic tissues (n cases = 2,431; HR per 30g/day increment in intake 1.16, 95%-CI 1.03, 1.32).DiscussionIn summary, higher intakes of red and processed meat were associated with a higher risk of colorectal cancer. Red meat consumption was also positively associated with risk of breast and prostate cancer, but these associations are not supported by most previous prospective studies. The positive association of poultry intake with cancers of the lymphatic and hematopoietic tissues requires further investigation.

AbstractIntroductionMeat consumption may be associated with a higher risk of cardiovascular diseases, but the evidence remains inconclusive. We prospectively examined the association between meat (total meat, red and processed meat, red meat, processed meat and poultry) intake and risk of ischemic heart disease (IHD) and stroke, including ischemic and haemorrhagic subtypes, in a large British cohort.Materials and methodsData were from UK Biobank participants who were free of IHD, stroke and cancer at recruitment (2006–2010), with available information on meat intake in the baseline touchscreen survey, and linked hospital admissions and death data for IHD, stroke, and stroke subtypes over follow-up (n = 441,700). We used multivariable Cox proportional hazards models to assess associations between meat consumption and risk of IHD, total stroke and ischemic and haemorrhagic stroke subtypes.ResultsOver a mean of 8.1 years of follow-up, 13,590 incident cases of IHD, 5,441 cases of total stroke, 2,258, cases of ischaemic stroke, and 949 cases of haemorrhagic stroke occurred. The risk of IHD was positively associated with intakes of total meat (Hazard ratio (HR) = 1.18, 95% Confidence Interval (CI) 1.09, 1.27 per 100 g/day higher intake), red and processed meat (HR = 1.15, 95% CI 1.08, 1.24 per 70 g/day higher intake), red meat (HR = 1.15, 95%, CI 1.07–1.24 per 50 g/day higher intake), processed meat (HR = 1.11, 95% CI 1.05, 1.16 per 20 g/day higher intake), and poultry (HR = 1.07, 95% CI 1.01, 1.13 per 30 g/day higher intake). The risk of total stroke was positively associated with intakes of total meat (HR = 1.15, 95% CI 1.02–1.29 per 100 g/day higher intake) and red and processed meat (HR = 1.14, 95% CI 1.03–1.27 per 70 g/day higher intake). Meat intake was not associated with ischaemic or haemorrhagic stroke.DiscussionThis large prospective study found that any meat consumption was associated with an increased risk of IHD and that red and processed meat consumption was associated with an increased risk of total stroke. Our findings for IHD and total stroke in relation to red and processed meat are in line with previous studies but our positive findings for poultry and IHD and null findings for red meat and ischaemic stroke are not, thus warranting further study.

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.
