Why Black beans may trigger symptoms
Black beans are very high in GOS. Even canned and rinsed, they're risky.
Gas can build when fermentable carbohydrates reach the large intestine and gut bacteria break them down. The same food may feel fine one day and harder during a sensitive week.
For IBS-sensitive people, the total meal matters. A food can feel different when it is paired with wheat, dairy, beans, sugar alcohols, large portions, alcohol, or a stressful day.
