Walnuts and the low FODMAP diet
Walnuts contain balanced omega-3 fats and minimal carbohydrates that digest predictably. The negligible fermentable sugar profile avoids overwhelming intestinal absorption during consumption. Standard portions provide crunch and nutrition without triggering colonic fermentation. Sensitive individuals incorporate them freely into baking applications safely.
