Pathology
- eating red meat (any amount, any type, beef, pork, lamb cited) may increase risk of premature death[1][2]
- processed red meat increases the risk of death further
- estimates of mortality hazzard ratio: 1.07-1.2[1][2]
- red meat consumption (including pork) associated with higher mortality than consumption of white meat (chicken, fish)[9]
- L-carnitine, abundant is red meat, is converted by gut bacteria to trimethylamine-N-oxide which is found in plasma of people who eat red meat, but not in vegans
- plasma levels of trimethylamine-N-oxide correlate with risk of cardiovascular disease[3][20]
- increases in red meat consumption among adults associated with increased all-cause mortality & cardiovascular mortality [14][17]
- absolute risk increase < 2%[14]
- once weekly red meat consumption unlikely to contribute to cardiovascular risk[18]
- substituting red meat with plant protein may reduce cardiovascular risk[17]
- decreases associated with decreased mortality risk[12]
- in men, less red meat is associated with lower cardiovascular risk[15]
- processed red meat is associated with increased risk for colorectal cancer & gastric cancer[7]
- increased risk for gastric cancer (RR-1.1)[19]
- red meat is probably carcinogenic but epidemiological data is not as strong as for processed red meat[7]
- red meat is associated with an increased risk for
- association of red meat with colorectal cancer is weak with no clear dose-response pattern[6]
- increases in red meat consumption linked to risk of diabetes mellitus type 2[23]
- red meat & processed meat consumption increase risk of type 2 diabetes[23]
- 2 servings of red meat per week increases risk[21]
- magnitidue of risk increases with greater red meat consumption
- risk may be associated with saturated fat consumption[4]
- red meat & processed meat consumption may increase risk of insulin resistance & steatosis[10]
- higher red meat intake in early adulthood may be a risk factor for breast cancer[5]
- a combination of legumes, poultry, nuts & fish may reduce the risk of breast cancer[5]
- 25 g of processed-meat daily (2 strips of bacon) associated with increased risk of dementia over 8 years, independent of the APOE-4 status[16]
- substituting processed red meat with plant protein reduces mortality[8]
- red meat allergies caused by tick bites a common cause of anaphylaxis (see tick-related allergy & alpha-gal syndrome)[11]
- a decrease of 3 servings per week of red meat associated with very small absolute risk reduction cardiovascular events, cancer incidence, & mortality based on 5 systematic reviews ranked as weak & based on low certainty evidence[13]
- processed red meat may be associated with a small increase in risk of dementia (RR=1.14)[22]
