Eggplants or otherwise known as aubergine in the United Kingdom are part of the nightshade family. It wasn’t until recently that I understood what nightshade vegetables actually were. Just as some of us have trouble digesting high FODMAP foods, the same can be said for nightshade vegetables. There are over 2,000 species of nightshades but the most popular vegetables are eggplant, tomatoes, potatoes and peppers. Reactions to these vegetables can be very similar to those who can not tolerate gluten. With all of that being said, eggplant is a great FODMAP safe vegetable option if nightshades are not an issue for you. According to the Monash University Application, a FODMAP safe portion is 1 cup.
