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 stout
Stout is a dark beer built on roasted barley, and that roast is the whole point: it is where the coffee and dark chocolate flavour comes from, and it is also why stout is gluten E like every other barley beer. Roasting changes the colour and the taste of the grain, not its gluten, so a pint of stout is off limits for coeliac disease and for non-coeliac gluten sensitivity in exactly the way a pale lager is. Beyond gluten, fermentation gives it high histamine (D) with moderate tyramine (C) and moderate sulfites (C), the usual reason a beer drinker gets a flushed face, a blocked nose or a thumping head from one pint. It grades poorly for SIBO (D) but only B for FODMAPs, so the gut complaints people report are more often about alcohol and carbonation than about fermentable sugars. Despite tasting of coffee, plain stout is caffeine free (A).
Watch for
- Gluten E.Roasted barley is still barley, and roasting does not degrade gluten, so stout is not safe on a coeliac diet no matter how dark or how dry it is
- Histamine D, the highest trigger on this page after gluten, produced during fermentation and made harder to clear because alcohol slows the diamine oxidase enzyme
- Milk stout, cream stout and sweet stout are brewed with added lactose that the yeast cannot ferment, so those styles carry lactose that a dry stout does not.The grades here describe a standard dry stout
- Moderate sulfites (C) and moderate tyramine (C) from fermentation, a combination that shows up as headache and flushing rather than gut symptoms
- Nitro stouts are poured with nitrogen rather than carbon dioxide, which gives the creamy head and much less dissolved gas.If your problem with beer is bloating and burping rather than gluten, that difference is real, but it changes nothing about the gluten or the histamine
