What are Nightshades ?

Nightshades are foods that contain lectins and small amounts of alkaloids, which act as natural pesticides. Nightshade foods belong to the Solanaceae family of plants (in the Solanum genus).

Most people can eat them with no problem, but some become sensitive to the alkaloids. Although cases are rare, eating nightshades could even lead to autoimmunity. If you’re one of the few, it certainly doesn’t feel rare. (Check out this handy list of autoimmune conditions.)

Nightshades are mostly fruits and vegetables, but also include spices and tobacco. You may hear “nightshade vegetables” and “nightshade fruits” as separate groups, but they are essentially the same thing: foods with higher-than-typical levels of alkaloids.

Check out this list of the most common nightshades:

  • Tomatoes and tomato products (ketchup, hot sauces, soups)
  • Tomatillos
  • Potatoes (white potatoes, red potatoes, but not sweet potatoes or yams)
  • Peppers (bell peppers, banana peppers, but not black pepper)
  • Eggplant
  • Sunberries
  • Goji berries
  • Groundcherries (not regular cherries)
  • Red spices (cayenne pepper, paprika, red pepper)
  • Ashwagandha
  • Tobacco

Notably, you may have a potato sensitivity but not a nightshade sensitivity. Potatoes contain multiple potentially harmful proteins and chemical compounds: solanine, lectin, chaconine, patatin, and a bunch of carbs.

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.

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 syndromeTrusted Source, type 2 diabetes, Alzheimer’s, and cardiovascular disease.

Are Nightshades Bad For Your Health?

While some alkaloids have positive effects on human health, others can affect them negatively. For example, the chemicals found in tobacco, a nightshade plant, can cause cancer.

The alkaloid found in nightshades is solanine. It functions as an insecticide while the plant is growing.Eating too much solanine can make you feel bad. When potatoes turn green, they have more alkaloids in them, and they taste more bitter. That is why people usually recommend throwing out green and/or sprouting potatoes. If you eat green potatoes, you may get sick to your stomach with nausea or diarrhea. You can also get a fever or headache.Normally, potatoes and other nightshade vegetables have an acceptable amount of alkaloids in them. You may feel some effects if you eat between two to five milligrams of solanine per kilogram of body weight. If you weigh around 150 pounds (68 kilograms) you would need to consume a minimum of 136 milligrams of solanine to feel ill.

For context, one eggplant has about 11 milligrams of solanine.

Studies show that potatoes can contain anywhere from 25-275 micrograms of alkaloids. The amount depends on the type of potato and where it was grown.

However, nightshades don’t cause inflammation directly. They may increase inflammation that is already there.How do you know if nightshades are bad for you? Experts recommend eliminating them from your diet for a few weeks. Then, reintroduce them and see how you feel. If you feel worse after reintroduction, you may have a sensitivity to nightshades.Whether or not there is any conclusive evidence about nightshades and inflammation, you should never eat any foods that make you feel bad, or that worsen any conditions you have.

I mentioned it before, but nightshade vegetables are not necessarily bad. However, if you have an autoimmune disease or chronic inflammation, you may have heard that you should avoid nightshades.

Research has shown that eliminating nightshade vegetables can help resolve inflammation, particularly in the joints. Because they can be triggers for some people with chronic illness, nightshade vegetables are eliminated during the first phase of the autoimmune protocol diet.

While anyone can have an allergy or intolerance to nightshade fruits and vegetables, there is a certain subset of people that have a greater propensity to not tolerating nightshades well.
