The leaves of nightshade garden plants should be avoided. Fruits are generally okay, but the leaves are toxic. That said, mine have eaten a nibble now and then before I catch them, and they are okay. Avoid more than a bite or two if you can, though.
Including the leaves of:
Tomatoes
Peppers
Eggplants
Potatoes
Tomatillos
Ground Cherry (Gooseberry)
Goji berry
Pimentos
