I found a new source, while looking at Leptin sensitivity issues, that gave a list of nightshade foods that made a lot of sense to other/additional sensitivities I have noticed:

What are Solanaceae? If you have an AI, DDD or DJD consider avoiding them:

A. American-grown soy! It has been hybridized with petunias, a nightshade, to be pesticide resistant (Round-Up)

B. All potatoes (NOTE: this does not include sweet potatoes because they are from the Marigold family)

C. Tomatoes (green are worse than any other type if you eat them as I do. The lycopene issue is offset by eating other red fruits of veggies. Watermelon for example blows tomatoes away as a source of lycopene.)

D. eggplant

E. sweet and hot peppers (including paprika, cayenne pepper and Tabasco sauce, but not black pepper)

F. ground cherries

G. tomatillos and tamarillos

H. garden huckleberry and naranjillas

I. pepinos and pimentos

J. Only the cape gooseberry is a nightshade (Physalis peruviana), Most gooseberries are not in the nightshade family. They are in the genus Ribes and are related to currants.

K. Blueberries, Strawberries, okra, artichokes, have some solanaceae toxin in them, but are not strict nightshades. If you have arthritis or another inflammatory condition you might want to rethink the ‘dogma’ that surrounds them. (kills me to tell you this too)

American grown soy will be a problem for me. Strawberries is sad, because I like those.
