Nightshade vegetables are a group of plants that belong to the Solanaceae family. This family includes a variety of plants, such as annual and perennial herbs, vines, lianas, epiphytes, shrubs, and trees, and includes a number of agricultural crops, medicinal plants, spices, weeds, and ornamentals. Some of the most common nightshade vegetables include:

• Tomatoes
• Eggplant
• Potatoes
• Peppers

Tobacco is also part of the nightshade family. Nightshade vegetables contain small amounts of alkaloids, including solanine, which may be toxic if consumed in large doses. However, there is no hard evidence that nightshade vegetables are bad for your health, and they are generally considered healthy for most people. In fact, they are rich in nutrients and often recommended as staples of a healthy diet. Some preliminary research shows that these vegetables may not be the best for people with certain inflammatory and auto-immune conditions like arthritis or inflammatory bowel disease, but they dont cause inflammation directly.
