Sensitivity notes
Why fructans food checker matters
Fructans are chains of fructose molecules found in wheat, onions, garlic, and many other foods. They're a type of FODMAP that can cause digestive symptoms in sensitive individuals because they're not well absorbed in the small intestine.
- Garlic-infused oil is low-FODMAP since fructans don't dissolve in oil
- Green parts of leeks and scallions are lower in fructans
- Sourdough bread may be better tolerated than regular wheat bread
- Spelt and ancient grains still contain fructans despite marketing claims
- Portion size matters - small amounts may be tolerable

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
