What to know about chestnut flour
Chestnut flour is naturally gluten free, and unlike almond or hazelnut flour it is a starch flour rather than a fat flour, which is why its grades look like a grain and not like a nut: A for gluten, histamine, histamine liberation, salicylates, sulfites and free glutamate, with moderate B marks for total FODMAPs, fructans, oxalate, nickel and SIBO fermentability. The oxalate line is the useful comparison, since almonds grade E there and chestnut flour grades B. The allergy question is the one that trips people up. Chestnut is a Fagaceae seed, related to oak and beech rather than to walnut or cashew, but it is a known member of the latex-fruit cluster alongside banana, avocado and kiwi.
Watch for
- Latex allergy is the flag to check, not tree nut allergy.Chestnut carries Cas s 5, a class I chitinase with a hevein-like domain that cross-reacts with the hevein in natural rubber latex, which is why chestnut appears in latex-fruit syndrome next to banana, avocado and kiwi. If latex gloves or balloons cause you trouble, chestnut is one to introduce cautiously
- Moderate rather than high on fructans and total FODMAPs, both graded B.A few tablespoons thickening a soup is a different proposition from a slice of castagnaccio made entirely of it, so this is a portion decision rather than a yes or no
- Graded B for oxalate and B for nickel.Neither is dramatic, but if you moved to gluten free baking specifically to escape almond flour on a stone or nickel protocol, chestnut is a step down (almonds grade E for oxalate and D for nickel) rather than a clean sheet
- Gluten free by nature, not always by facility.Chestnut flour is a niche mill product often produced alongside wheat, so for coeliac disease the certification on the bag matters more than the botany
- It is sweet and hygroscopic, with far more sugar and less fat than a nut flour, so it clumps, absorbs moisture from the air and sours or goes musty faster than most flours.A bag that smells sharp or fermented rather than sweet and chestnutty has turned
