Nightshade fruits and vegetables are a broad group of plants from the solanum and capsicum families. Nightshade plants contain poisons, one called solanine. While ingesting nightshade plants can be fatal, fruits and vegetables in this same classification of plant — many of which you’ll find at your local grocery store — are actually safe to eat.
This is because the amount of this toxic compound is lowered to nontoxic levels once the fruits and vegetables ripen. Still, the leaves and berries of the deadly nightshade plant are toxic and shouldn’t be consumed.
Find out exactly which of the nightshades are the most nutritious.
Tomatoes are a staple of many diets for numerous reasons. In addition to how easy they are to grow, they’re also packed with nutrition. This fruit is high in vitamins A and C, and is also a good source of iron, potassium, vitamin B-6, manganese, and dietary fiber.
According to Penn State University’s Extension program, current research suggests that tomatoes contain carotenoids, powerful antioxidants that protect the body from certain types of cancers. Lycopene, the most common carotenoid found in tomatoes, may help reduce the risk for pancreatic, prostate, and digestive cancers.

Potatoes are one of the most abundantly grown foods used in the Western world. They’re also part of the perennial nightshade family that can be mildly poisonous when eaten before they’re ripe, while the skin is still green.
Potatoes are great sources of vitamin C, which helps aid immunity. They also contain enough potassium, vitamin B-6, and fiber to make a healthier staple than you may realize. Moreover, they contain carotenoids, flavonoids, and caffeic acid, all forms of phytonutrients known to promote health benefits, according to the USDA.
There are also many different types of varieties, which have different health benefits. Potatoes are rich in vitamins A, B, C, and E, along with iron and zinc. They provide an easy way to get necessary, critical amounts of nutrients for people living in developing worlds.
Potatoes aren’t as healthy when they’re prepared with high amounts of fats, salts, and oils, like french fries. Because nothing beats a homestyle staple, try this take on roast potatoes.

To find fresh goji berries, you’ll have to visit a Chinese plantation. But they’re also typically found at specialty food stores in dried form, sometimes labeled as wolfberries.
Goji berries contain protein and numerous healthy amino acids such as tyramine. They’re high in antioxidants, which help immune function and cell health. If you’re trying them for the first time, know that it’s possible to be allergic to them. You’ll want to stop eating them should you develop a rash or become ill.
To get more beneficial nightshades in your diet, try adding goji berries into this double berry cobbler.
Blueberries contain solanine alkaloid like nightshade plants, though they aren’t technically a nightshade plant. Blueberries are often touted as a superfood because many believe they contain cancer-preventing ingredients. They’re high in antioxidants, which are known to reduce inflammation. With that in mind, blueberries are thought to prevent inflammatory diseases such as metabolic syndrome, type 2 diabetes, Alzheimer’s, and cardiovascular disease.
According to researchers at the Gerontological Society of America, evidence from recent studies show that blueberries contain flavonoids, specifically one called anthocyanin, that’s directly associated with cognitive benefits.
A cup of blueberries provides a quarter of your daily vitamin C needs, as well as supplying some dietary fiber. The fiber, when combined with probiotics in yogurt, can keep your gastrointestinal tract in good working order.
