   Narrative review. Red meat: unprocessed mammalian muscle meats, including beef, veal, pork, lamb, mutton, horse or goat. Processed meat: meat treated through salting, curing, fermentation, smoking or other processes to enhance flavour or improve preservation. Curing with nitrite can produce carcinogenic N-nitroso compounds, at less than 1 to 130 ppb in cured meats, activated by CYP2E1. Ingested haem can catalyse the nitrosation of endogenous secondary amines and exert pro-oxidative effects by catalysis of lipid peroxidation in the gastrointestinal tract. High-temperature cooking produces heterocyclic aromatic amines, which cytochrome P450 enzymes N-hydroxylate and N-acetyltransferases or sulfotransferases convert to DNA-binding intermediates. Many of these chemicals form DNA adducts.

   Sodium and potassium nitrite are used in curing mixtures to develop and fix the colour of meat, to inhibit microbial growth and to develop characteristic flavours. Acceptable daily intake 0.07 mg nitrite ion/kg body weight per day, based on methaemoglobin formation. Use as food additives supplied about 17% (range 1.5 to 36.0%) of overall nitrite exposure. Margin of exposure for endogenous NDMA formed from nitrite at the ADI 4.2 × 10^5; for preformed NDMA plus NDEA in processed food, below 10,000 in all age groups at high exposure. Nitrosamines formed from nitrite added at authorised levels could not be clearly distinguished from those present without added nitrite. There was evidence linking preformed NDMA with colorectal cancer and some evidence linking nitrite plus nitrate from processed meat with colorectal cancer.

Exposure 0 to 208.9 ng/kg body weight per day across surveys, age groups and scenarios.

   Narrative review. Heterocyclic aromatic amines form during high-temperature cooking of meat, poultry and fish, in amounts that increase with cooking time and temperature; PhIP and AαC can reach 50 ppb or more in well-done meat and poultry. In model systems with amino acids and sugars, creatine or creatinine is the precursor of the imidazo moieties of the aminoimidazoarenes, which are more potent mutagens than the amino acid pyrolysates. Hepatic CYP1A2 accounts for an estimated 70% of PhIP metabolism in humans, mainly by N-oxidation to genotoxic N-hydroxy-PhIP. Most N-hydroxy-heterocyclic amines are bioactivated by human NAT2 to reactive esters; N-acetoxy-PhIP is stable enough to isolate; SULT1A1 and SULT1A2 catalyse binding of N-hydroxy-PhIP to DNA. The proposed reactive intermediate is the heteroaryl nitrenium ion; N-hydroxy-PhIP forms the adduct N-(2′-deoxyguanosin-8-yl)-PhIP (dG-C8-PhIP).

   A two-component Rieske-type oxygenase/reductase, CntA and CntB, encoded in a carnitine utilisation gene cluster in 39 human microbiota reference genomes, cleaves the C-N bond of carnitine to trimethylamine and a four-carbon compound. Deletion of cntA or cntB abolished trimethylamine formation from carnitine in A. baumannii; purified CntA and CntB with NADH were necessary and sufficient in vitro. CntB is a predicted NAD(P)-dependent reductase with flavin and plant-type [2Fe-2S] ferredoxin domains; CntA carries a Rieske [2Fe-2S] centre and a mononuclear iron centre, and its glutamate 205 is essential for catalysis.

   Carnitine is enriched in red meat; the red meat diet contained 3.8-fold and 7.9-fold more carnitine than the white meat and non-meat diets. After 4 weeks, plasma TMAO rose about threefold on the red meat diet against the white meat or non-meat diets (P < 0.0001), with median absolute increases of 5.9 and 5.7 μM against non-meat and white meat; urine TMAO also rose. Red meat reduced the fractional renal excretion of TMAO (P < 0.05) and increased that of carnitine, γ-butyrobetaine and crotonobetaine. Isotope tracers (n = 13) showed more TMA and TMAO formed from carnitine, not choline, on the red or white meat diet than on the non-meat diet. Saturated fat did not affect TMAO. Plasma TMAO fell within 4 weeks of stopping red meat. The authors state that the direct contribution of TMAO to cardiovascular disease pathogenesis in humans is unclear.

    High against low red meat intake, 27 cohorts: summary relative risk 1.11 (95% CI 1.03 to 1.19), heterogeneity P = 0.014, I2 33.6%. Associations attenuated in models of fresh red meat separated from processed meat, in better adjusted models, in women and outside the United States. Categories of median intake above 100 g/day (6 studies): 1.20 (1.11 to 1.29); categories up to 100 g/day 1.00 to 1.03, not significant; each 70 g increment (13 studies) 1.05 (0.97 to 1.13). The authors conclude that red meat intake does not appear to be an independent predictor of colorectal cancer risk.

    Red meat: unprocessed mammalian muscle meat such as beef, veal, pork, lamb, mutton, horse or goat. Processed meat: meat transformed through salting, curing, fermentation, smoking or other processes to enhance flavour or improve preservation. More than 800 epidemiological studies assessed. Colorectal cancer: positive associations with red meat in 7 of 14 cohorts and with processed meat in 12 of 18 cohorts; a meta-analysis of 10 cohorts gave relative risks of 1.17 (95% CI 1.05 to 1.31) per 100 g/day of red meat and 1.18 (1.10 to 1.28) per 50 g/day of processed meat. Processed meat classified as carcinogenic to humans (Group 1) on sufficient evidence for colorectal cancer; chance, bias and confounding judged unlikely explanations. Red meat classified as probably carcinogenic to humans (Group 2A) on limited evidence in humans and strong mechanistic evidence; chance, bias and confounding could not be ruled out with the same confidence. Mechanistic evidence: haem iron mediates formation of N-nitroso compounds and lipid oxidation products in the digestive tract; 300 or 420 g/day of red meat increased putative N-nitroso-derived DNA adducts in two intervention studies; meat heated at high temperature contains heterocyclic aromatic amines, which are genotoxic.

    The panel suggests that adults continue current unprocessed red meat consumption and continue current processed meat consumption (weak recommendations, low-certainty evidence); 11 of 14 panellists voted for each, 3 for a weak recommendation to reduce. For a decrease of 3 servings a week of unprocessed red meat: 12 randomised trials (54,000 participants) gave low- to very low-certainty evidence of little or no effect on cardiometabolic outcomes and cancer; 23 cohorts (1.4 million participants) gave 1 to 6 fewer major cardiovascular events and cases of type 2 diabetes per 1000 persons over an average 10.8 years; 17 cohorts (2.2 million) gave 7 fewer lifetime cancer deaths per 1000. For processed meat: 1 to 12 fewer cardiometabolic events per 1000 (10 cohorts, 778,000 participants) and 1 to 8 fewer cancer events per 1000 over a lifetime (31 cohorts, 3.5 million). The panel did not rate up for dose-response because of potential residual confounding. Randomised trials were limited by small differences in meat consumption between groups.

    9 guidelines with 12 recommendations; each advised less consumption of foods containing nonintrinsic sugars. Guidelines scored poorly on AGREE II for rigour of development, applicability and editorial independence; 5 recommendations set limits from less than 25% to less than 5% of energy; quality of the supporting evidence was low to very low. The authors concluded that the guidelines do not meet criteria for trustworthy recommendations.
