Prospective studies examining the association between coffee and tea consumption and gastric cancer risk have shown inconsistent results. We investigated the association between coffee (total, caffeinated and decaffeinated) and tea consumption and the risk of gastric cancer by anatomical site and histological type in the European Prospective Investigation into Cancer and Nutrition study. Coffee and tea consumption were assessed by dietary questionnaires at baseline. Adjusted hazard ratios (HRs) were calculated using Cox regression models. During 11.6 years of follow up, 683 gastric adenocarcinoma cases were identified among 477,312 participants. We found no significant association between overall gastric cancer risk and consumption of total coffee (HR 1.09, 95%‐confidence intervals [CI]: 0.84–1.43; quartile 4 vs. non/quartile 1), caffeinated coffee (HR 1.14, 95%‐CI: 0.82–1.59; quartile 4 vs. non/quartile 1), decaffeinated coffee (HR 1.07, 95%‐CI: 0.75–1.53; tertile 3 vs. non/tertile 1) and tea (HR 0.81, 95%‐CI: 0.59–1.09; quartile 4 vs. non/quartile 1). When stratified by anatomical site, we observed a significant positive association between gastric cardia cancer risk and total coffee consumption per increment of 100 mL/day (HR 1.06, 95%‐CI: 1.03–1.11). Similarly, a significant positive association was observed between gastric cardia cancer risk and caffeinated coffee consumption (HR 1.98, 95%‐CI: 1.16–3.36, p‐trend=0.06; quartile 3 vs. non/quartile 1) and per increment of 100 mL/day (HR 1.09, 95%‐CI: 1.04–1.14). In conclusion, consumption of total, caffeinated and decaffeinated coffee and tea is not associated with overall gastric cancer risk. However, total and caffeinated coffee consumption may be associated with an increased risk of gastric cardia cancer. Further prospective studies are needed to rule out chance or confounding.

“…Caffeine, kahweol, and cafestol in coffee may contribute to a protective effect against cancer [68]. Based on the evaluation of two prospective and eight casecontrol studies, which showed no statistically signifi cant association between coffee consumption and gastric cancer, the WCRF/AICR concluded that high consumption of coffee "probably" has no relation with the risk of gastric cancer [3].…”

“…Based on the evaluation of two prospective and eight casecontrol studies, which showed no statistically signifi cant association between coffee consumption and gastric cancer, the WCRF/AICR concluded that high consumption of coffee "probably" has no relation with the risk of gastric cancer [3]. In a more recent systematic review and meta-analysis of 23 studies (7 cohort studies and 16 case-control studies) [68], coffee intake showed no effect on gastric cancer when all studies were combined (OR = 0.97, 95% CI = 0.86-1.09), with a combined risk estimate of 1.02 (95% CI = 0.76-1.37) for cohort studies, 0.90 (95% CI = 0.70-1.15) for population-based casecontrol studies, and 0.97 (95% CI = 0.83-1.13) for hospital-based case-control studies. Notwithstanding that risk estimates differed signifi cantly according to country of origin, with North American studies presenting a signifi cantly higher risk, this meta-analysis showed no overall effect of coffee consumption on gastric cancer risk.…”

Background and Objective: A comprehensive overall review of gastric cancer (GC) risk and protective factors is a high priority, so we conducted the present study. Methods: Systematic searches in common medical electronic databases along with reference tracking were conducted to include all kinds of systematic reviews (SRs) about GC risk and protective factors. Two authors independently selected studies, extracted data, and evaluated the methodological qualities and the quality of evidence using R-AMSTAR and GRADE approaches. Results: Betacarotene below 20 mg/day, fruit, vegetables, non-fermented soy-foods, whole-grain, and dairy product were GC protective factors, while beta-carotene 20 mg/day or above, pickled vegetables, fermented soy-foods, processed meat 30g/d or above, or salty foods, exposure to alcohol or smoking, occupational exposure to Pb, overweight and obesity, helicobacter pylori infection were GC risk factors. So we suggested screening and treating H. pylori infection, limiting the amount of food containing risk factors (processed meat consumption, beta-carotene, pickled vegetables, fermented soy-foods, salty foods, alcohol), stopping smoking, avoiding excessive weight gain, avoidance of Pb, and increasing the quantity of food containing protective components (fresh fruit and vegetables, non-fermented soy-foods, whole-grain, dairy products). Conclusions: The conclusions and recommendations of our study were limited by including SRs with poor methodological bases and low quality of evidence, so that more research applying checklists about assessing the methodological qualities and reporting are needed for the future.
