Avoid daily red meat, especially fried, to reduce oral cancer risk

Red meat consumption shows a strong association with oral and pharyngeal cancer risk, and frying dramatically amplifies this risk. Limiting both overall red meat intake and fried meat preparation is advisable.

Red meat and cancer risk in a network of case-control studies focusing on cooking practices

A case-control study network with 1465 oral and pharyngeal cancer cases and 11,656 controls found that each 50 g/day increase in red meat raised oral/pharyngeal cancer risk by 38% (OR = 1.38; 95% CI: 1.26-1.52). Fried meat was associated with a nearly threefold increase (OR = 2.80; 95% CI: 2.02-3.89). Models were adjusted for known confounding factors including alcohol and tobacco use.

High red meat intake linked to elevated oral cancer risk

Elevated beef consumption was associated with substantially increased cancer risk, particularly among individuals with certain metabolic enzyme variants. Reducing red meat intake and balancing it with higher vegetable consumption may help lower risk.

Interaction between dietary intake and GSTM1 and GSTT1 polymorphisms in head and neck cancer risk: a case-control study in São Paulo, Brazil

Authors: CARVALHO, Marcos Brasilino de, CURIONI, Otavio A., GATTÁS, Gilka Jorge Figaro, MARCHIONI, Dirce Maria Lobo

Published: January 1, 2011

Hospital-based case-control study with 103 histologically confirmed head and neck cancer cases and 101 controls in São Paulo, Brazil. Highest tertile of beef consumption was associated with OR = 10.79 (95%CI: 2.17-53.64) among carriers of the GSTM1 null genotype and OR = 3.41 (95%CI: 0.43-27.21) among GSTT1 null carriers. The ratio of animal-to-vegetable food consumption showed a dose-response pattern with OR = 2.35 (95%CI: 0.27-19.85) in the intermediate tertile and OR = 3.36 (95%CI: 0.41-27.03) in the highest tertile, indicating that higher animal-to-plant food ratios were associated with progressively greater cancer risk.
