Why nickel food checker matters

Nickel is a metal found in many foods including chocolate, nuts, and leafy greens. People with nickel allergy (often showing as contact dermatitis) may also react to dietary nickel, causing skin and digestive symptoms.

Avoid cooking acidic foods in stainless steel cookware
Canned foods often have higher nickel content
Chocolate, nuts, and legumes are common high-nickel foods
First-draw water from taps may be higher in nickel - let it run
Vitamin C may help reduce nickel absorption

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
