To avoid or not avoid the nightshade
Certain foods from the nightshade family can contribute to migraines. Widely consumed vegetables such as eggplant, potatoes, tomatoes, sweet peppers, hot peppers, paprika, and cayenne pepper are all part of the nightshade family of vegetables. In reality there are over 2,800 species of plants that belong to this group1. There are those who believe that migraine sufferers should avoid this group of vegetables altogether as the nightshade contains neurotoxic alkaloids that can trigger a migraine. Neurotoxic alkaloids have also been found to impair muscle and joint function.
