Often you find it harder to control your urge to buy some extra kilos of blueberries whenever you find them in the market. Undoubtedly they look alluring with that nice blue hue and tastes sweetly delicious thus fruit lovers can barely say no to this berry sister.

But if you’ve noticed there is an argument over this much-loved fruit blueberry saying it might be nightshade.

So now you’re wondering what’s the word nightshade stands for actually. Or maybe you’re hesitating while taking some extra bite of blueberries thinking if it’s a ‘Nightshade’.

To explain to you what does nightshade means why some vegetables are called nightshade and if blueberries do fall in that category.

What are nightshade fruits and vegetables? Why are they called nightshade?

Fruits and vegetables that are part of the Solanaceae (also known as Solanum) family are known as nightshade.

Solanaceae is a large group of flowering plants that includes many vegetables, fruit, seed, and herb. What these Solanaceae family members have in common is the presence of different alkaloids in them.

Alkaloids are a group of nitrogenous elements that are originated from plants. They are poisonous molecules depending on their variants and can cause harm to health.

But two types of alkaloids that are found in plant-based foods- Capsaicin and Solanine are edible. These are also known as glycoalkaloids. Nightshade fruits and vegetables contain these glycoalkaloids and can be consumed.

Nightshade fruits and vegetables include tomatoes, eggplants, all kinds of peppers, black paper, potatoes, ground cherries, goji berries, etc. Though there are claims that say eating nightshade foods can be harmful to certain health issues, it’s not been proved yet.

The reason why fruits and vegetables containing glycoalkaloids are named nightshade is not very clear yet.

Some say it’s because many of these fruits and vegetables are grown in dark and shady places. Some flowers of these family blooms at night are another idea that supports the naming of these specific plants.

Many also believe the name nightshade indicated the negative side of these poisonous plant groups. But none of these theories are solid. However, scientifically the word nightshade is used to specify the plants that produce toxic alkaloids.
