Sensitivity notes
Why fructans food checker matters
Fructans are chains of fructose molecules found in wheat, onions, garlic, and many other foods. They're a type of FODMAP that can cause digestive symptoms in sensitive individuals because they're not well absorbed in the small intestine.
- Garlic-infused oil is low-FODMAP since fructans don't dissolve in oil
- Green parts of leeks and scallions are lower in fructans
- Sourdough bread may be better tolerated than regular wheat bread
- Spelt and ancient grains still contain fructans despite marketing claims
- Portion size matters - small amounts may be tolerable

What to know about romanesco
Romanesco is the lime-green brassica with the fractal spiral head, and despite being sold as romanesco broccoli it is botanically a cauliflower: Brassica oleracea from the same botrytis group, with the curd arranged in self-similar cones instead of a dome. The question people arrive with is whether it therefore carries cauliflower's mannitol problem, and on our grades it carries a diluted version of it. Cauliflower grades high FODMAP, high polyol and poor for a low-fermentation SIBO approach. Romanesco lands one band milder on all three: moderate on total FODMAPs, moderate on polyols, moderate on fructans, moderate on fermentability. It also sits well below both of its famous relatives on salicylate, where cauliflower and broccoli are each graded high and romanesco is only mild, and far below broccoli on free glutamate. The practical read is a middle vegetable. It is gentler than cauliflower on the polyol that drives the bloating, gentler than broccoli on the chemistry that drives the salicylate and umami reactions, and still a brassica that will ferment if you eat a whole head in one sitting.
Watch for
- Moderate on polyols where cauliflower is graded high.Same compound family, smaller load, so a normal side portion often clears the threshold that a bowl of cauliflower rice would blow straight through
- Moderate on fructans as well, which is the broccoli side of its parentage.Total FODMAP load is the two subgroups stacked together, which makes romanesco a portion vegetable rather than an unlimited one
- Moderate rather than poor on a low-fermentation SIBO plan, so it belongs in the test-it band instead of the avoid list where cauliflower and broccoli both sit.Roasting does not reduce the fermentable fraction, only the volume you can comfortably eat
- Only mild on salicylates, which is unusual for this family and the single most useful thing on the page.If cauliflower and broccoli give you the salicylate pattern of headache, flushing or itch rather than gas, romanesco is the brassica worth retesting
- Moderate nickel and moderate free glutamate, both dose-dependent and only worth logging if you already track systemic nickel allergy syndrome or glutamate reactions
