“…Finally, the difference in eating habits might have affected. It is well known that Asians have a high consumption of spicy foods and that excessive consumption of spicy foods is associated with development of dyspepsia [39]. The effect of eradication may also be underestimated compared with non-Asian studies due to the differences in food culture.…”

Background: Previous studies on the effect of Helicobacter pylori eradication on functional dyspepsia (FD) are conflicting. We performed a comprehensive meta-analysis on this issue according to region and prevalence of H. pylori. Methods: Randomized controlled trials (RCTs) evaluating the effect of eradication of H. pylori on functional dyspepsia up to December 2018 were searched through PubMed, EMBASE, and the Cochrane Library. Subgroup analyses by the outcome measure, region, and prevalence of H. pylori were performed. All data were analyzed with Review Manager 5.3. Results: Eighteen RCTs were included in our meta-analysis. Overall, the H. pylori eradication group showed significant improvement of symptoms compared with the control group (risk ratio (RR) = 1.18; 95% confidence interval (CI): 1.07–1.30, p < 0.01). There was moderate heterogeneity among studies (I2 = 34%) and the number needed to treat (NNT) was 15.0. Helicobacter pylori eradication improved dyspeptic symptoms both in low (<50%) and high (≥50%) H. pylori prevalence regions (RR = 1.21 and 1.17; 95% CI: 1.02–1.44 and 1.06–1.29, I2 = 49% and 5%, respectively.) In the analysis of studies from Asia, however, the effect of eradication on improvement of dyspepsia was not significant (RR = 1.14; 95% CI: 0.99–1.33, p = 0.08, I2 = 37%). Conclusion: Overall, H. pylori eradication provides significant improvement of symptoms in functional dyspepsia patients regardless of H. pylori prevalence. However, in the analysis of studies from Asia, the eradication did not significantly improve dyspeptic symptoms. In this region, eradication for dyspepsia can be individualized.

“…Our research concentrated on seven types of specific diets: fatty food, spicy food, sweet food, tea, alcohol, coffee, and unprocessed water/food that have been identified in the literature [ 19 , 20 , 31 ]. Spicy food, sweet snacks, and fatty food have been previously suspected as risk factors, while tea and coffee consumption have been reported to have a controversial relationship with FD [ 33 – 35 ]. Our study found that except for the preference for coffee, FD patients were more likely to report adverse dietary habits of interest than symptomless individuals ( Table 4 ).…”

BackgroundFunctional dyspepsia (FD) refers to a group of upper gastrointestinal syndromes, subdivided into two types: postprandial distress syndrome (PDS) and epigastric pain syndrome (EPS). The etiology of FD remains unclear; however, unhealthy dietary habit is one potential underlying cause. We aim to explore the association of poor dietary habits with FD and its subtypes.Material/MethodsA validated epidemiological questionnaire was designed to investigate dietary habits and gastrointestinal syndromes. Citizens in the Baotun community of Dongguan were invited to complete the study questionnaire. All participants were asked to undergo a physical examination and a blinded physician interview. The study was conducted from June 2015 to June 2016. FD was diagnosed using ROME III criteria. The association between investigated dietary habits and dyspeptic symptoms were explored.ResultsThere were 1,304 adult residents recruited for the study survey; 165 residents had existing organic dyspepsia (OD), 203 residents were diagnosed with FD, and the other 936 participants, who were without dyspeptic symptoms or functional gastrointestinal diseases, were regarded as the control group. Subtype diagnosis indicated 61 participants had EPS, 66 participants had PDS, and 76 participants had coexisting EPS and PDS. Unhealthy dietary habits were more prevalent in the FD group than in the control groups (75.86% versus 37.50%; p<0.001). FD was found to be associated with irregular mealtime, dining out, fatty food, sweet food, and coffee (p<0.05). The impact of each dietary factor varied with FD subtypes.ConclusionsCertain types of dietary habits were positively correlated with the prevalence of FD. FD subtypes showed relatively different associations with dietary factors.

“…Following the screening on title and abstract, 140 articles remained for full text screening. Forty articles met the inclusion criteria and were included in this systematic review (Figure 1) [21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60].

The Alignment of Dietary Intake and Symptom-Reporting Capture Periods in Studies Assessing Associations between Food and Functional Gastrointestinal Disorder Symptoms: A Systematic Review

et al. 2019

Food ingestion is heavily implicated in inducing symptoms of irritable bowel syndrome (IBS) and functional dyspepsia (FD), which affect over one-third of adults in developed countries. The primary aim of this paper was to assess the alignment of dietary assessment and symptom-reporting capture periods in diet-related studies on IBS or FD in adults. Secondary aims were to compare the degree of alignment, validity of symptom-reporting tools and reported significant associations between food ingestion and symptoms. A five-database systematic literature search resulted in 40 included studies, from which data were extracted and collated. The food/diet and symptom capture periods matched exactly in 60% (n = 24/40) of studies, overlapped in 30% (n = 12/40) of studies and were not aligned in 10% (n = 4/40) of studies. Only 30% (n = 12/40) of studies that reported a significant association between food and global gastrointestinal symptoms used a validated symptom-reporting tool. Of the thirty (75%) studies that reported at least one significant association between individual gastrointestinal symptoms and dietary intake, only four (13%) used a validated symptom tool. Guidelines to ensure that validated symptom-reporting tools are matched with fit-for-purpose dietary assessment methods are needed to minimise discrepancies in the alignment of food and symptom tools, in order to progress functional gastrointestinal disorder research.

Relationship between spicy food intake and chronic uninvestigated dyspepsia in Iranian adults

Abstract: High consumption of spicy foods is associated with greater odds of CUD, frequent postprandial fullness and epigastric pain. Further studies, particularly of a prospective nature, are needed to confirm our findings.
