Is tiger nuts high in nitrites?

Watch for

• Botanically a tuber, not a nut, so tree nut and peanut allergy do not apply.The caveats are practical rather than botanical: tiger nuts are frequently packed on shared lines with real nuts, so check the allergen statement rather than assuming
• Tiger nut allergy does exist independently, reported as part of pollen-food syndrome, so "not a nut" is not the same as "cannot cause a reaction".Itchy mouth or throat after tiger nuts in someone with pollen allergy is a recognised pattern
• High in nickel (graded D).Unusual for a root vegetable and worth logging if you are running a low-nickel elimination, since tiger nuts are exactly the food people add when they cut out nuts
• Very high fibre with a big resistant starch fraction, plus moderate FODMAP, fructan and GOS grades.This is prebiotic behaviour by design, which is great for the microbiome and unpleasant if you have IBS or SIBO. Soaking or lightly roasting them, and building the portion up slowly, is the standard fix
• Moderate oxalate (graded C).Not the extreme end that sesame or almonds occupy, but not the free pass the "just a root vegetable" framing implies
