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 refined grains
Refined grains are the umbrella for white flour, white rice, degermed cornmeal, instant grains and most packaged baked goods and breakfast cereals. Refining means the bran and the germ have been milled away, leaving the starchy endosperm. That removes the fibre, most of the magnesium and B vitamins, and, counterintuitively, most of the lectins and phytates too, since those concentrate in the bran. Our data grades the category D for gluten, because the refined grain most people eat is wheat, and E for inflammation. It is otherwise clean on histamine, nickel, sulfites and lactose. This is more of a nutrition-pattern page than a sensitivity page, and it is worth being honest about that.
Watch for
- Graded D for gluten, which reflects the category being wheat dominated.Whether a specific refined grain contains gluten depends entirely on the parent grain: refined wheat, barley and rye do, white rice and degermed corn do not
- Graded E for inflammation, the strongest claim on this record, and E for EoE compatibility.Both are pattern judgements about refined starch rather than a reaction to a single compound
- Enriched is not the same as whole.Enrichment puts back a short list of B vitamins and iron. It does not put back the fibre, the magnesium or the germ oils that were milled out
- The trade-off runs both ways.Refined flour is lower in lectins and phytates than wholemeal, which is why some people with sensitive guts genuinely feel better on white bread than on brown, and why the fibre advice does not fit everyone
- Our data grades this category clean on the individual FODMAP columns, but that is the category average, not a green light for wheat-based members of it.Wheat flour and bread carry their own fructan grades on their own pages
