The Study
Detection of FODMAP Intolerances and Symptom Improvement Following Dietary Intervention in Patients from Northwestern Mexico
This study watched what happened when 21 people changed what they ate to see if their stomach felt better. It saw that their symptoms got better, but it didn't compare them to people who didn't change their diet. So we can't be sure the diet was the reason they felt better.
Analysis score
Maximum 44 for a cross-sectional study.
Where the score came from
Some people’s tummies get upset by natural and added sugars in food. Doctors tested them to find which sugars caused problems, then helped them eat less of those sugars.

Summary
Based on the study abstract and findings.
- 1Yes — people felt much better, with less pain and discomfort daily, without losing nutrition or calories.
- 261% couldn't handle fructans, 56% couldn't handle sorbitol.
- 3After eating less of these sugars for 4 weeks, bloating, pain, and gas dropped from moderate to mild levels.

In 21 adults with ongoing gastrointestinal symptoms, a personalized low-FODMAP diet based on breath test results for specific sugar intolerances led to a measurable decrease in the severity of bloating, gas, pain, diarrhea, and constipation after four weeks.
In a group of 21 adults, switching to a personalized low-FODMAP diet reduced fructose and fructan intake to very low levels without changing total calories or the amounts of protein, fat, and carbohydrates consumed.
In Northwestern Mexico, 56% of adults with gastrointestinal symptoms have sorbitol intolerance, and this is linked to high intake of processed foods and oral care products containing sorbitol.
Among adults with ongoing digestive symptoms, breath tests showed that 61% could not digest fructans, 56% could not digest sorbitol, 39% could not digest lactose, and 33% could not digest fructose; 64% had intolerances to two or more of these sugars.
