“…So, the dietary indices could be used for chronic disease prevention and management by not only nutritionists but also clinicians and gastropathy patients. Increasing evidence has indicated the correlation between these indexbased dietary patterns and the risk of gastric cancer, such as the MDS (13,14) , the healthy eating index (HEI) (15) and the dietary inflammatory index (DII) (16)(17)(18) . The Mediterranean dietary pattern (MDP), which is characterised by a high intake of vegetables, fruits, legumes, non-refined cereals, nuts, olive oil, moderate intake of fish and dairy products and low intake of red meat, could prevent gastric cancer.…”

Dietary indices are widely used in diet quality measurement, and the index-based dietary patterns are related to gastric cancer risk. To evaluate the relationship between different kinds of index-based dietary patterns and gastric cancer risk, we systematically searched four English-language databases and four Chinese-language databases. The quality of studies was assessed by the Newcastle–Ottawa Scale. Meta-analyses were performed to estimate the association between gastric cancer incidence and different types of index-based dietary patterns. The OR and hazard ratios (HR) of gastric cancer incidence were calculated by regression models in case–control studies and prospective cohort studies, respectively. The studies were pooled in the random effects model to calculate the summarised risk estimate of the highest quantile interval of dietary indices, taking the lowest as the referent. The dietary indices included different versions of Mediterranean diet score (MDS) and dietary inflammatory index (DII), healthy eating index, Chinese Food Pagoda score and food index score. The meta-analysis was carried out for studies on MDS and DII. The combined OR of gastric cancer for the highest MDS v. the referent was 0·42 (95 % CI 0·2, 0·86), and the combined HR was 0·89 (95 % CI 0·68, 1·17). The combined OR for DII was 2·11 (95 % CI 1·41, 3·15). Higher Mediterranean dietary pattern consumption might reduce gastric cancer risk, while higher inflammatory diet pattern consumption might increase gastric cancer risk.

“…A case control study in Italian adults revealed that higher pro-in ammatory diet was associated with 2.35 times increased risk of gastric cancer [36]. Moreover, in Korean population, people in the highest tertile of DII had a 63% greater risk of gastric cancer compared to those in the lowest [34]. A case control study in Tabriz, Iran showed that consumed more pro-in ammatory diet had 3.5 times greater risk of gastric cancer than those who consumed a more anti-in ammatory diet [35].…”

“…Given that those with in ammatory diet would have 2.5 times greater risk of gastric cancer [34,36], we considered the odds ratio of 2.5. We assumed the type I error of 5%, study power of 80% (β = 0.20) and the ratio of controls to cases as 2.…”

Background No report is available about diet-disease associations in the understudied region of Afghanistan. Although inflammatory potential of diet has been linked with several cancers, information about gastric cancer is scarce. This study aimed to investigate the relationship between dietary inflammatory index (DII) and odds of gastric cancer in Afghanistan. Methods In this hospital-based case-control study, we enrolled 90 newly-diagnosed cases of gastric cancer and 180 age (± 5) and sex-matched controls. All cases were pathologically confirmed gastric cancer patients, with no history of any type of other pathologically confirmed cancers. Controls were healthy individuals and relatives of patients in the hospital. Dietary assessment was done by a pre-tested food frequency questionnaire. DII was calculated based on energy-adjusted amounts of several foods and nutrients with inflammatory or anti-inflammatory potential, as introduced by earlier studies. Results Mean age of study participants was 54 years, of them 73% were males. After adjustment for age and sex, individuals in the highest tertile of DII were 2.47 times (95% CI: 1.31–4.66) more likely to have gastric cancer compared with those in the lowest tertile. Further adjustment for other potential confounders did not substantially affect the association; such that participants with the greatest DII had approximately 3.59 times (95% CI: 1.16, 11.02) increased odds of gastric cancer than those with the lowest adherence. Additional adjustment for BMI strengthened the association (OR: 3.75; 95% CI: 1.14–12.30). Conclusion We found a significant positive association between inflammatory potential of diet and risk of gastric cancer. Further studies with prospective nature are required to confirm this association.

Gaussian graphical models (GGMs) are novel approaches to deriving dietary patterns that assess how foods are consumed in relation to one another. We aimed to apply GGMs to identify dietary patterns and to investigate the associations between dietary patterns and gastric cancer (GC) risk in a Korean population. In this case-control study of 415 GC cases and 830 controls, food intake was assessed using a 106-item semiquantitative food frequency questionnaire that captured 33 food groups. The dietary pattern networks corresponding to the total population contained a main network and four subnetworks. For the vegetable and seafood network, those who were in the highest tertile of the network-specific score showed a significantly reduced risk of GC both in the total population (OR = 0.66, 95% CI = 0.47–0.93, p for trend = 0.018) and in males (OR = 0.55, 95% CI = 0.34–0.89, p for trend = 0.012). Most importantly, the fruit pattern network was inversely associated with the risk of GC for the highest tertile (OR = 0.56, 95% CI = 0.38–0.81, p for trend = 0.002). The identified vegetable and seafood network and the fruit network showed a protective effect against GC development in Koreans.
