Onions
Onions contain fructans, a type of carbohydrate that can ferment in the gut, leading to gas, bloating, and further irritation of the gastrointestinal tract during diarrhea. This can prolong symptoms and increase discomfort. For individuals with a sensitive stomach or those experiencing gastrointestinal upset, avoiding onions is advisable to prevent exacerbating diarrhea. [5]
Corn
Corn, mainly when consumed in its whole form, is high in insoluble fiber, which can be tough on a digestive system already compromised by diarrhea. The body has difficulty breaking down the outer shell of corn kernels, which can lead to increased digestive tract irritation and an aggravation of diarrhea symptoms.
