Sensitivity notes
Why histamine food checker matters
Histamine is a compound naturally present in many foods, especially aged, fermented, or preserved items. In sensitive individuals, excess histamine can cause headaches, flushing, hives, digestive issues, and other symptoms. Your body normally breaks down histamine, but some people have reduced capacity to do so.
- Focus on fresh foods - histamine builds up as food ages
- Cook and eat meals fresh; avoid leftovers sitting more than 24 hours
- Be cautious with fermented foods, aged cheeses, and cured meats

Serving size, prep, and portion notes for oat bran
Oat bran is the outer layer of the oat groat, milled off and sold on its own, so it is best understood as oats with the volume turned up. It carries considerably more soluble beta-glucan fibre per spoon than rolled oats, which is why it grades clean on the anti-inflammatory scale and fits DASH and Mediterranean patterns well. The same concentration works in the other direction too: we grade it moderate on FODMAPs and on SIBO fermentation, because the fermentable carbohydrate that oats carry arrives concentrated as well. The grade people misread is gluten, which sits borderline rather than clean. Oats are not a gluten grain, but oat bran is routinely grown, harvested and milled alongside wheat and barley, and a small minority of people with coeliac disease react to avenin, the oat protein itself, even when the batch is certified.
Watch for
Moderate on FODMAPs and strongly portion-dependent: two tablespoons stirred into something and a full bowl of oat bran porridge are not the same exposure, because the bran concentrates the oat fructans and GOS / Borderline on gluten for two separate reasons: milling cross-contact, which certified gluten-free oat bran solves, and avenin sensitivity in a minority of coeliacs, which it does not / Poor fit for SIBO protocols, since highly fermentable soluble fibre is precisely what feeds bacterial overgrowth in the small intestine / Moderate on lectins, oxalate and nickel, which matters if you are working through any of those three rather than a gut protocol / Genuinely clean on histamine, histamine liberation, salicylates, lactose, dairy protein and glutamates, so it is rarely the culprit in those investigations
