Eating nightshade vegetables in moderation can be great for your health. This article covers the nutritional benefits and potential downsides of nightshade vegetables, and offers tips for incorporating them into your meals with recipes, alkaloids, and sensitivity information.

1. What Exactly Are Nightshade Foods?

Nightshade foods are a family of plants known as Solanaceae, which includes over 2,000 species, many of which are edible. These plants contain alkaloids, natural compounds that can affect the body. While some people believe nightshades can cause inflammation or other health issues, most are nutritious and safe to eat.
