   HCAs and PAHs form at high temperatures; population studies have not established a definitive cancer link

   Витяг

   “"Population studies have not established a definitive link between HCA and PAH exposure from cooked meats and cancer in humans." The NIH-AARP Diet and Health Study found that "high consumption of well-done, fried, or barbecued meats was associated with increased risks of colorectal" cancer, while "other studies have found no association with risks of colorectal or prostate cancer." ”

   Розрахунок

   NCI is the authoritative US source for the HCA/PAH cancer hypothesis. The fact sheet explicitly states that the population-level evidence is inconsistent. This is the core basis for framing the entry as "overrated": the mechanistic story (rodent mutagenicity) is strong, but the human epidemiology is mixed and effect sizes where positive are modest (RR 1.1-1.3 range). The NCI does not endorse a quantitative human cancer risk estimate attributable to cooking method.

   Незалежність

   NCI synthesizes multiple cohort studies (NIH-AARP, PLCO, EPIC) using independent methodology. The fact sheet is a position statement, not a primary meta-analysis; Sinha 2005 below is one of the studies it references.

   Meat, meat cooking methods and preservation, and risk for colorectal adenoma

   Статистика

   OR 1.21 (95% CI 1.06-1.37) for colorectal adenoma, highest vs lowest well-done red meat consumption

   Витяг

   “"Well-done red meat was associated with increased risk of colorectal adenoma (OR, 1.21; 95% CI, 1.06-1.37). Our study of screening-detected colorectal adenomas shows that red meat and meat cooked at high temperatures are associated with an increased risk of colorectal adenoma." ”

   Розрахунок

   Sinha et al. 2005 is the largest single study quantifying the well-done-meat / colorectal adenoma association. The OR of 1.21 is the headline figure used for the native encoding. Adenoma is a precursor lesion to colorectal cancer; the OR for invasive CRC tends to be similar or slightly lower in pooled analyses. Applying 1.21 to the SEER baseline lifetime CRC risk of 4.1% gives ~5.0%. The Sinha paper also reported smaller, non-significant associations for chicken and fish cooking methods.

   Незалежність

   The Sinha 2005 analysis used PLCO screening cohort data (n=38,513), independent of the NIH-AARP cohort underlying many NCI fact sheet references. Both cohorts feed into broader IARC and World Cancer Research Fund evaluations.

   Heterocyclic amines: Mutagens/carcinogens produced during cooking of meat and fish

   Статистика

   10+ HCAs identified as rodent carcinogens; HCA content in ordinary dishes is low and not sufficient by itself to explain human cancer

   Витяг

   “"More than ten kinds of HCAs, actually produced by cooking or heating of meat or fish, have now been isolated and their structures determined, most being previously unregistered compounds. ... When HCAs were fed in the diet, rodents developed cancers in many organs, including the colon, breast and prostate, and one HCA produced hepatomas in monkeys. ... While the content of HCAs in dishes consumed in ordinary life is low and not sufficient in itself to explain human cancer..." ”

   Розрахунок

   Sugimura et al. document the rodent-to-human gap directly. HCAs are unambiguously carcinogenic in laboratory rodents at doses orders of magnitude higher than typical human dietary intake. The translation to human cancer at dietary exposure levels is the contested step. This source establishes the mechanistic plausibility and the IARC 2A/2B classifications without overstating the human risk magnitude.

   Незалежність

   Sugimura's group at the National Cancer Center Research Institute (Japan) discovered the first dietary HCAs in the late 1970s. This review is methodologically distinct from the US cohort epidemiology and provides the rodent-mechanism evidence base.
