The LFD wil receive advice on how to follow a low FODMAP diet. They wil follow this diet for 4 weeks. Thereafter they receive advice on how to reintroduce high FODMAPs again.

Control group. Participants follow their regular gluten-free diet (GFD), with no changes to their diet. They wil receive the same dietary advice as the LFD-group after the 4-week study.

Irritable Bowel Syndrome

Effect of FODMAP Restriction on Persistent GI-symptoms in Coeliac Patients

Effect of Fermentable Oligo-, di-, and Monosaccharides and Polyols (FODMAP) Restriction on Persistent GI-symptoms in Coeliac Patients

Measured by score in gastrointestinal symptom rating scale for irritable bowel syndrome (GSRS-IBS). The scoring is based on a 7-grade Likert scale in which 1 point indicates no symptoms and 7 points the most severe gastrointestinal symptoms. The total score in the gastrointestinal symptom rating scale for irritable bowel syndrome is calculated as a mean value of all 13 items. The maximum score is 91 and the minimum score is 13. A higher score means more severe symptoms. A score higher than 1 standard deviation (SD, 0.66 points) compared to the control mean are considered to have increased gastrointestinal symptoms.

Altered faecal microbiota diversity, measured as a change in diversity and/or abundance or strains from baseline and after 4 weeks on a low FODMAP diet.

Changes in short form-36 (SF-36) as a measure of quality of life. SF-36 covers four physical health perceptions (physical functioning, role limitations because of physical health problems, bodily pain, and general health) and four mental health concepts (vitality, social functioning, role limitations because of personal or emotional problems, and mental health perceptions). Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The range of score is 0 to 100, where a higher score means better quality of life and the lower the score the more disability. A total score for mental health and physical health is calculated as an average of the subscales, with a range from 0 to 100. Here also the higher the score the better quality of life. The standardized combined scores in several populations have a mean of 50 and standard deviation 10. The scoring wil be performed as in the SF-36 scoring manual.

Participants will drink 450 milliliters of the juice at time 0.

Participants will eat 400 to 500 grams of frozen mango pulp, along with 250 milliliters of water at time 0.

Participants will eat 400 to 500 grams of a mixture of fresh natural fruit containing mango (73%) and pear (27%), along with 250 milliliters of water at time 0.

Participants will drink 250 milliliters of the standard glucose load at time 0.

Glucose Intolerance

Capillary glucose will be taken every 15 minutes for two hours (starting at time 0) to calculate the area under the curve which is the glycemic index, for each of the products.

Glycemic Index of Mango and Pear in Different Solid Products and Drinks

Comparison of the Glycemic Index of a Drink Made of Natural Concentrated Mango Puree With Natural Concentrated Pear Juice With That of Other Five Products Based on Mango and Pear in Different Solid Products and Drinks

Glycemic index will be calculated for 450 milliliters of this juice. The results will be expressed as mean ± standard deviation for each with a significance level of 0.05 for all the statistical tests.

Glycemic index will be calculated for 400 to 500 grams of mango along with 250 milliliters of water. The results will be expressed as mean ± standard deviation for each with a significance level of 0.05 for all the statistical tests.

Glycemic index will be calculated for a standard 50-gram glucose load. This will be done twice by every participant. The results will be expressed as mean ± standard deviation for each with a significance level of 0.05 for all the statistical tests.
