BACKGROUND: N-glycolylneuraminic acid (Neu5Gc) is a non-human red-meat-derived sialic acid immunogenic to humans. Neu5Gc can be metabolically incorporated into glycan chains on human endothelial and epithelial surfaces. This represents the first example of a "xeno-autoantigen", against which circulating human "xeno-autoantibodies" can react. The resulting inflammation ("xenosialitis") has been demonstrated in human-like Neu5Gc-deficient mice and contributed to carcinoma progression via antibody-mediated inflammation...

This study aimed to estimate the consumption of meat and products derived from hunting by the consumer population and, specifically, by hunters and their relatives. For this purpose, a survey was conducted on the frequency of consuming meat from the four most representative game species in Spain, two of big game, wild boar (Sus scrofa) and red deer (Cervus elaphus) and two of small game, rabbit (Oryctolagus cunulucus) and red partridge (Alectoris rufa), as well as of processed meat products (salami-type sausage) made from those big game species...

BACKGROUND: Only two case-control studies have examined the associations between consumption of meat products and endometriosis risk with inconsistent results. Consumption of animal products has the potential to influence endometriosis risk through effects on steroid hormones levels. OBJECTIVES: To determine whether higher intake of red meat, poultry, fish, and seafood are associated with risk of laparoscopically-confirmed endometriosis STUDY DESIGN: 81,908 participants of the prospective Nurses' Health Study II were followed from 1991-2013...

Over the past decade, there has been a growing awareness of a new allergic syndrome known as alpha-gal allergy or alpha-gal syndrome, commonly recognized as a red meat allergy. We performed a review of the literature to identify articles that provide both background on this syndrome in general and any reports of reactions to medications or medical devices related to alpha-gal syndrome. Alpha-gal syndrome results from IgE to the oligosaccharide galactose-α-1,3-galactose, expressed in the meat and tissues of noncatarrhine mammals...

Studies have suggested that higher meat intake may increase colorectal cancer (CRC) risk while higher vegetable intake may reduce this risk. There is a substantial lag between the time of exposure to a risk factor (or protective factor) and incidence of cancer. For CRC, in particular, the time from formation of adenoma to occurrence of CRC takes from 10 to 15 years, or even more. This study correlates food disappearance data per capita for vegetable and meat with future age-adjusted CRC rates in USA. The lag weights, with a high confidence, showed that there is a positive correlation between the red meat availability and CRC age-adjusted incidence rates with a lag of at least 17 years and an Almon polynomial degree of 2...

Colorectal cancer is a common cause of morbidity and mortality in the United States. Most colorectal cancers arise from preexisting adenomatous or serrated polyps. The incidence and mortality of colorectal cancer can be reduced with screening of average-risk adults 50 to 75 years of age. Randomized controlled trials show evidence of reduced colorectal cancer-specific mortality with guaiac-based fecal occult blood tests and flexible sigmoidoscopy. There are no randomized controlled trials on the effectiveness of colonoscopy to reduce colorectal cancer-specific mortality; however, several randomized controlled trials comparing colonoscopy with other strategies are in progress...

BACKGROUND: High red and processed meat intakes are associated with increased colorectal cancer (CRC) risk. The effect of eliminating or reducing red and processed meat consumption on CRC burden was not previously quantified in Denmark. The aim of this study was to calculate the possible effects of reductions in red and processed meat consumption on future CRC incidence in the Danish adult population. METHODS: Under six scenarios of prevalence exposure (meat consumption) the number of CRC cases in Denmark for a 30-year period (2016-2045) was estimated and compared to the projected number of CRCs if the prevalence of meat consumption remains constant...

In navigating decisions about what to eat, people both construct and rely on a food-choice identity. Yet food choice is multifaceted, as people apply different dietary schemas to different types of food, engaging various domains of food-choice identity. In this paper, we focus on dietarian identity: one's thoughts, feelings, and behaviors with respect to consuming or eschewing animal products (here, pertaining to red meat, poultry, fish, eggs, and dairy). First, we draw upon Rosenfeld and Burrow's (2017a) Unified Model of Vegetarian Identity in order to develop a Dietarian Identity Questionnaire (DIQ)...

Overland transport of ore concentrate from the Red Dog lead/zinc mine in northwest Alaska to its seaport has historically raised concerns among local subsistence users regarding the potential impacts of fugitive dust from the operation, including the potential uptake of metals into caribou meat. Caribou are an integral part of life for northern Alaska Natives for both subsistence and cultural reasons. The Western Arctic caribou herd, whose range includes the Red Dog mine, transportation corridor, and port site, sometimes overwinter in the vicinity of mine operations...

On October 26, 2015, IARC published a summary of their findings regarding the association of cancer with consumption of red meat or processed meat (IARC 2015; The Lancet Oncology 2015). The Working Group concluded that there is limited evidence in human beings for carcinogenicity from the consumption of red meat and inadequate evidence in experimental animals for the carcinogenicity of consumption of red meat. Nevertheless, the working group concluded that there is strong mechanistic evidence by which ingestion of red meat can be linked to human colorectal cancer and assigned red meat to Group 2A "probably carcinogenic to humans"...

BACKGROUND: Food recommendations to improve cancer prevention are generally based on epidemiologic data and remain inconsistent. These epidemiologic studies, while controversial, have generally produced results that caution against the consumption of high-fat foods, including eggs, red meat, and full-fat dairy, such as butter and cheese. Yet, limited data exist assessing the quality of individual sources of these foods and the effect each has after its consumption. This study set out to assess the impact sources of food within the same groups from animals raised differently on variables associated with health in human studies...

To quantify the association between prediagnosis lifestyles with the risk of second primary cancers (SPCs) and survival of patients with gastric first primary cancer (FPC). We recruited 574 gastric patients from two major public hospitals in North Portugal (2001-2006). Smoking, alcohol and dietary habits in the year before FPC diagnosis were evaluated. Patients were followed up to 31 December 2011 for an SPC and to 31 May 2017 for vital status. Cox proportional hazards regression was used to estimate adjusted hazard ratios for incidence of an SPC or death...
