What to know about radicchio
Radicchio, the red Italian chicory, has a short and specific trigger profile: high salicylates, and very little else. It grades clean on histamine, gluten, lactose, nightshades, sulfites and nickel, and its oxalate content is unrated here rather than high. The bitterness that defines it comes from sesquiterpene lactones, the daisy family compounds, not from the salicylates, so taming that bitterness by grilling the head or by buying a winter Treviso sweetened by frost changes the flavour without changing the grade that matters. The practical catch with radicchio is that people rarely eat it on purpose. It is a standard component of tricolore and mixed Italian salad bags, so it arrives in the log as "salad".
Watch for
- High in salicylates, shared with the rest of the chicory family.A tricolore salad that pairs radicchio with endive stacks two high salicylate leaves into one bowl rather than one neutral side
- Frequently hidden in bagged leaves.Tricolore, misticanza and Italian mixes all use radicchio for colour, so you can get a regular dose without ever buying a head
- Oxalate is unrated for radicchio in our data, so it is not a leaf to lean on if you are counting oxalate precisely for stone prevention
- Moderate on total FODMAPs by portion, though it grades low on fructans specifically.The inulin that makes chicory root fibre a FODMAP problem is in the root, not in these leaves
- A daisy family plant.People with Compositae contact allergy, the ragweed and chrysanthemum group, occasionally react on the hands while prepping chicories
