Flax flour: moderate in nickel; low in salicylate, FODMAPs and oligosaccharides. If you're sensitive to any of these, check it against your profile before eating.
Intolerances
- NickelModerate
Flax flour is the whole seed milled, hull included, and the hull is where a seed keeps its nickel. It is used in small quantities, which is what holds the level here.

- SalicylateLow
Ground flax seed, low like the whole seed. Grinding releases the oils but does not raise the salicylate.
- FODMAPsLow
Flax flour is a seed, used a tablespoon at a time. A flour concentrates whatever the seed held into a form used by the cupful, which is why the same plant can be low as a portion and high as a baked good. This food is not among the 55 grain products behind the per-portion FODMAP figures, so its level is a placing and not a measurement.

- OligosaccharidesFODMAPsLow
Flaxseed carries mucilage rather than fructans - a long, water-binding chain that swells instead of fermenting quickly. It is used a tablespoon at a time, which keeps it well inside this level.

Note about this food
Whole flaxseeds are better tolerated in histamine and FODMAP sensitivities because they are less processed, reducing the risk of histamine release or fermentation in the gut. Ground or pre-milled flax can oxidize quickly, which may increase inflammatory responses and intolerance symptoms. Buying whole grains and grinding them fresh ensures better stability, freshness, and safer digestion.
