Sensitivity notes

Why low fermentation food checker matters

SIBO (Small Intestinal Bacterial Overgrowth) diets focus on reducing fermentable foods that feed bacteria in the small intestine. Low-fermentation foods help manage symptoms like bloating, gas, and abdominal discomfort.

  • Low-fermentation eating reduces food for overgrown bacteria
  • Meal spacing (4-5 hours) allows the MMC to clear the gut
  • Avoid grazing - structured meals are better
  • Some find the elemental diet helpful under medical supervision
  • Address underlying causes with your healthcare provider

What to know about whole grain bread

Whole grain bread has a health-food reputation, yet it is often the loaf that bloats people the most. Keeping the bran and germ means keeping more of the wheat fructans and fermentable fiber than a white loaf, so it rates a full grade higher on FODMAPs than plain white bread. It still contains gluten, so it is no safer for celiac disease or gluten sensitivity. If a wholesome sandwich leaves you gassy and distended, the extra bran, not a lack of nutrition, is usually the reason.

Watch for

  • Contains gluten, so switching to whole grain does nothing for celiac disease or non-celiac gluten sensitivity
  • Higher in fructans than white bread because the retained bran and germ carry extra fermentable carbs
  • Rates high FODMAP, a common cause of bloating and gas after an otherwise healthy sandwich
  • A long, slow sourdough ferment lowers fructans, so a genuine sourdough is gentler than a fast-risen wholemeal, though it is still wheat and still contains gluten
