NCT04243187

Brief Summary

The oligosaccharide content (raffinose, stachyose, and verbascose) in legumes would be responsible for gastrointestinal symptoms (bloating, pain, meteorism), associated with its consumption. We would evaluate consumption of 3 varieties of chilean native beans, and evaluate gastrointestinal symptoms produced along with expired H2 test, to correlate this with the amount of oligosaccharide content.

Outcome Measures

Primary Outcomes (2)

  • Gastrointestinal symptoms

    We will evaluate the difference in the THE GASTROINTESTINAL SYMPTOM RATING SCALE (GSRS), with the intake of different native beans

    4 months

  • Gastrointestinal symptoms

    We will evaluate the difference in the "bristol stool chart" with the intake of different native beans

    4 months

Secondary Outcomes (1)

  • Exhaled Hydrogen Test

    4 months

Study Arms (1)

Clinical Study

EXPERIMENTAL

9 visits, once a week, for bean intake (80 grams of dried beans, soaked for 12 hours, cooked in new water for 1.5 - 2 hours. This is approximately 160 grams of cooked beans). Four varieties of beans (3 native and 1 commercial) will be analyzed, which will be consumed in duplicate by participants (8 visits). A ninth visit will be made to perform a exhaled hydrogen test with raffinose (5 grams), as a positive control.

Other: Chilean Native Beans

Interventions

In each visit the participant would have to: 1. Fill a survey of gastrointestinal symptoms and basal bowel movements ("THE GASTROINTESTINAL SYMPTOM RATING SCALE (GSRS)) 2. Fill a survey of food consumption 3. Bean plate intake 4. Expired hydrogen test, which consists of exhaling air in a syringe every 20 minutes for 12 times (4 hours in total). During this time the participant can do quiet activities (not physical activity). 5. Fill surveys of gastrointestinal symptoms (online or on paper), during the hydrogen test, at 12 and 24 hours (3 times). During this time (1 day before and 2 days later) the participant cannot eat other bloating foods (legumes, cauliflower, broccoli, lettuce, cabbage, artichokes, onions, topinambur and others described in the food survey).
