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 saccharin
Saccharin is the oldest artificial sweetener, discovered in 1879, and it is still the one people ask about most because of the cancer scare. It is clean on almost every food-chemistry trigger we track: no gluten, no lactose, no FODMAPs, no oxalate, no sulfites, no nickel, no caffeine and no tyramine. Its two honest caveats are gut tolerance (we grade it borderline for fermentation and SIBO, and human trials have found saccharin can shift the gut microbiome and glucose response in some people) and a mild borderline flag for histamine, histamine release and salicylate. If you are searching whether saccharin causes cancer, the short answer is that the 1970s rat bladder tumours came from a mechanism that does not exist in humans, and the US warning label was removed in 2000.
Watch for
- Borderline for gut fermentation and SIBO.Saccharin is not absorbed and passes through to the colon, and randomised human work has shown non-nutritive sweeteners including saccharin can alter gut bacteria and glycaemic response in a subset of people, which is the most plausible reason for bloating after a few sweetened drinks a day
- Mildly flagged for histamine and histamine release, so it sits in the "watch it if you are reactive" band rather than the trigger band.If sweetened drinks reliably give you flushing or itching, log the brand, not just the sweetener
- Tabletop packets are mostly not saccharin.A pink packet is largely dextrose with a bulking agent such as cream of tartar, so a reaction to the packet may be to the filler rather than the sweetener itself
- Saccharin is chemically a sulfonamide (benzoic sulfimide).Cross reaction with sulfa antibiotic allergy is considered unlikely, but it is a real question worth raising with your clinician rather than guessing
- Borderline for salicylate, not high.If you are on a strict salicylate elimination, saccharin is usually a lower-risk sweetener than fruit-derived or herbal ones
