BackgroundNumerous individual and environmental factors including diet may play an important role in the pathophysiology of irritable bowel syndrome (IBS). It is unclear to what degree dietary intake is affected in individuals with IBS. We aimed to perform a systematic review and meta‐analysis to summarize dietary intake of adults with IBS and to compare dietary intake between adults with IBS and non‐IBS controls.MethodsOvid MEDLINE, Embase, Cochrane, CINAHL, and Scopus were searched through February 2023 for clinical trials and observational studies measuring usual diet in adults with IBS. Pooled weighted averages were estimated for total energy, macronutrient, and micronutrient data. Mean differences (MD) in nutrient intake were estimated for adults with IBS versus non‐IBS controls using a random effects model. Heterogeneity was assessed by the inconsistency index (I2).Key ResultsSixty‐three full‐text articles were included in the review of which 29 studies included both IBS and control subjects. Nutrients not meeting the recommended intake level for any dietary reference values in the IBS population were fiber and vitamin D. Meta‐regression by female proportion was positively correlated with total fat intake and negatively correlated with carbohydrate intake. Comparisons between participants with IBS and controls showed significantly lower fiber intake in participants with IBS with high heterogeneity (MD: −1.8; 95% CI: −3.0, −0.6; I2 = 85%).Conclusions and InferencesThis review suggests that fiber and vitamin D intake is suboptimal in IBS; however, overall dietary intake does not appear to be comprised. Causes and consequences of reduced fiber in IBS deserve further study.Results of this systematic review and meta‐analysis suggest that fiber and vitamin D intake is suboptimal in IBS. However, overall intake of other macro‐ and micronutrients does not appear to be compromised. Causes and consequences of reduced fiber and Vitamin D intake in IBS deserve further study.

Seven hundred and thirty-nine men aged 40-69 years and 976 women aged 25-69 years (65% of a stratified random sample of the population) answered a validated food-frequenc:y questionnaire focused on carbohydrates and which included questions on breakfast cereal eating and smoking habits. Increased intakes of non-starch pdysaccharide (NSP) in breakfast cereals were associated with higher intakes of NSP from other sources, and also with higher intakes of vitamin C and with less smoking. Insoluble NSP intakes were doubled in people eating bran-enriched cereals regularly. compared with those who did not eat such cereal. The government target for the population of an average NSP intake of 18 g/day was consistently met only by people eating whole-grain or bran-enriched cereals regularly.

A 7-day diet history was completed by 1213 subjects in Ireland between the ages of 8 and 80 years. Subjects were divided into breakfast skippers, cereal eaters or non-cereal eaters.Ninety-seven per cent of the population ate breakfast. Sixty-eight per cent were breakfast-cereal consumers and of these 62% ate breakfast six to seven times per week. The contribution which breakfast cereal makes to the total daily nutrient intake was calculated for males and females separately, and also for the two age-groups 8-18 years and >18 years. Iron intakes were lower than the RNI for all females but cereal consumers appeared more likely to achieve their RNI than br0akfas.t skippers and non-cereal consumers. Breakfast-cereal consumers had significantly higher intakes of vitamins B,, B2, niacin, folate.BIZ, vitamin D, calcium and iron. For females not consuming a breakfast cereal. mean nutrient intakes of folate and calcium were lower than the RNI. From this study, it appears that breakfast cereal consumption makes a significant contribution to nutrient intake in the Irish diet.
