Adherence to the pro-inflammatory diet in relation to prevalence of irritable bowel syndrome

This 2019 cross-sectional study investigated the association between dietary inflammatory index (DII) score and odds of irritable bowel syndrome (IBS) and its severity among Iranian adults. The 3363 participants completed a validated Dish-based 106-item Semi-quantitative Food Frequency Questionnaire (DS-FFQ) and a modified Persian version of Rome III questionnaire to determine their dietary intakes and IBS severity. After adjustment for potential confounders were made, the data showed those adults in the highest quintile of DII score had higher risk of having IBS compared with those in the lowest quintile (OR = 1.36). Although no significant association was observed between a pro-inflammatory diet and severity of IBS symptoms, a significant association was discovered between DII score and IBS among women (OR = 1.41). Also, overweight or obese (BMI ≥ 25 kg/m2) individuals in the top quintile of DII score were 64% more likely to have IBS, compared to those in the bottom quintile. Salari-Moghaddam et al. (2019) summarises the findings: among Iranian adults, consumption of a pro-inflammatory diet was associated with increased odds of IBS, in particular among women and those with BMI ≥ 25 kg/m2.

This multicenter double-blind placebo-controlled trial published in 2016 involved placing participants with functional gastrointestinal symptoms on a 3-week gluten-free diet (GFD) before randomly assigning the responsive patients to gluten intake (5.6g per day) or placebo for 7 days, and subsequently switching the subjects into the other group (crossover). Symptoms and quality of life were monitored […]

Fructan, rather than gluten, induces symptoms in patients with self-reported non-celiac gluten sensitivity

Skodje et al. (2018) investigated the effect of gluten and fructan (common component of gluten) separately in individuals with self-reported gluten sensitivity (gastrointestinal discomfort which improves after gluten withdrawal). In this double-blind crossover study, 59 participants, for whom celiac disease was excluded and who were on a gluten-free diet already, were randomly selected to go […]
