HONEST FLAG: no parsnip-specific efficacy trials. The documented item is a contact-safety one.
Study dose vs. serving
No established benefit dose.
Medscape and DermNet NZ phytophotodermatitis literature. A dietary-exposure study (Beattie et al.) found normal culinary amounts did not lower the erythema threshold.
Use caution if
You're managing carbohydrate intake closely, parsnips are starchier than most root vegetables
You're sensitive to furanocoumarins, raw parsnip greens/sap can cause skin irritation in sunlight; the root itself is fine

Watch
PHYTOPHOTODERMATITIS: skin contact with parsnip sap (especially wild parsnip) followed by UV-A causes phototoxic dermatitis and burns. Agricultural and grocery workers handling parsnip, celery and parsley are classic cases. The risk is chiefly SKIN CONTACT from handling or wild harvesting, not eating cooked parsnip.
