What Are Nightshade Vegetables? 

Nightshade fruits and vegetables are parts of flowering plants that you can eat that are part of the Solanaceae group. In the Solanaceae group, there are over 2,000 plant types. However, only a fraction of them is edible.

Nightshades have a negative reputation. That is because some plants may be hallucinogens and narcotics. Additionally, there is a belief that they are not good for people with arthritis or autoimmune disorders in general.

Some people may have an allergy or sensitivity to nightshades. That is because there is a substance in nightshades called alkaloids that is bitter and serves as an insect repellent.

There is limited evidence that alkaloids aggravate arthritis, but some studies show that they can inflame the intestinal lining of irritable bowel syndrome.

However, is it necessary to avoid nightshades altogether if you have an autoimmune disorder? Nightshade vegetables and fruits have a small number of alkaloids to the point that they will not likely make a difference if eaten in moderation.
