FODMAP Consumption by Adults from the French Population-Based NutriNet-Sante Cohort

Background: Fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPs) are increasingly studied because they are suspected unfavorably to impact health (irritable bowel syndrome in particular). However, little is known about FODMAP intake in the general population, or which groups are more likely to consume them, because their intakes are usually assessed in inpatient settings. Objectives: This study aimed to describe FODMAP consumption in a large French cohort and its association with sociodemographic and lifestyle characteristics. Methods: This cross-sectional study described FODMAP intakes in 109,362 volunteers (78.0% female, mean age 43.8 +/- 14.7 y) from the French NutriNet-Sante cohort, using an ad hoc FODMAP composition table. Associations between FODMAP intakes and sociodemographic characteristics were investigated using x(2) tests or Kruskal-Wallis tests according to the qualitative or quantitative status of the variable, and multinomial logistic regressions were performed after adjusting for energy intake in sensitivity analyses. Eligible participants had completed >= 3 detailed 24-h food records. Results: We observed a mean intake of 18.9 +/- 9.5 g/d FODMAPs in this French cohort, and 11.7% of participants had intakes <9 g/d (i.e., low-FODMAP diets). Participants with FODMAP intakes <9 g/d were more likely to have lower caloric intakes (Delta = 383 kcaVd compared with participants with FODMAP intakes >= 16 g/d), to be smokers, to have lower incomes, and to have lower levels of physical activity. Total FODMAPs accounted for a mean intake of 18.9 +/- 9.5 g/d, which was 3.7 +/- 2.0% of total energy intake. The highest intake of FODMAPs was represented by lactose followed by excess fructose, fructans, polyols, and galacto-oligo-saccharides. Conclusions: FODMAP consumption by a large sample of adults from the general population is similar to 19 g/d, with half of the population having a FODMAP intake >16 g/d.

Automated summary

The study found that the average intake of FODMAP in a large French cohort is 18.9 g/day, with half of the population having an intake higher than 16 g/day. People with lower FODMAP intake were more likely to have lower caloric intake, be smokers, have lower incomes, and engage in lower levels of physical activity.
