Nightshade family vegetables. Based on Harvard T.H. Chan SPH oxalate data (2024).
44 foods in this collection
Nightshades — tomatoes, peppers, eggplant, potatoes — are mostly low-to-moderate in oxalate, which means the group does not need blanket avoidance for stone patients. Tomato products are the nuance: fresh tomatoes are low, while tomato paste and sauce concentrate the oxalate into smaller servings. The nightshade reputation for joint or autoimmune concerns is a separate topic from oxalate; on the stone table, this family is generally manageable with the usual portion-and-pair approach.
