What to know about wheat bran
Wheat bran is the outer layer of the wheat kernel, and concentrating that layer concentrates its triggers. It is a gluten food that is also one of the most fructan-dense ingredients in the pantry and unusually high in nickel, which is why a spoonful of bran cereal or a "high-fibre" muffin can bloat you far more than the same amount of regular flour.
Watch for
- Very high in fructans, the FODMAP most linked to bloating: because it is a concentrated bran, the dose per spoon is higher than in ordinary wheat flour
- Contains gluten, so wheat bran is not suitable for coeliac disease or gluten sensitivity
- High in nickel, a common contact-allergen trigger: whole-grain bran layers carry far more nickel than refined grains, which matters for systemic nickel allergy
- Poor for SIBO, since the fermentable fibre feeds bacterial overgrowth in the small intestine
