What to know about yellow crookneck squash
Yellow crookneck squash is the bumpy, curve-necked heirloom summer squash, and in this database it has one genuinely high grade: lectins. Everything a sensitive eater usually checks first comes back clean, so histamine, oxalate, nickel, glutamate, tyramine and sulfites are all unflagged, it is not a nightshade, and it is not a gluten risk. Salicylates land in the moderate band. If crookneck squash bothers you while other gentle vegetables do not, lectins are the first thing to test rather than the last.
Watch for
- Graded high in lectins, the only high rating on this vegetable and the reason it appears on lectin avoidance lists alongside cucumbers and other gourds
- In gourds the lectin load concentrates in the skin and the seed cavity, which is exactly what a crookneck develops as it grows: picked small the skin is thin and the seeds are undeveloped, picked large it turns bumpy, thick skinned and seedy
- Thorough cooking is the other standard lectin lever, so raw crookneck in a salad is a different exposure from crookneck that has been simmered or roasted through
- Salicylates grade moderate, which matters only if you are running a strict salicylate elimination
- We do not carry a FODMAP rating for this specific cultivar, so treat it as untested rather than cleared if you are following a formal low FODMAP phase
