This limited research in animals and test tubes suggests that people with IBD may benefit from eliminating or reducing nightshades. But research is needed in humans before more definitive recommendations can be made.

However, there may be some connection between increased intestinal permeability, or leaky gut, and autoimmune conditions like celiac disease, multiple sclerosis, and rheumatoid arthritis 15 , Some experts believe that leaky gut could contribute to higher levels of inflammation all over the body that worsen disease symptoms 17 , Based on this belief, some have suggested that nightshades may increase intestinal permeability and aggravate the symptoms of these autoimmune conditions, as well.

Many people with these diseases have eliminated nightshades from their diets and report improvement in symptoms, but evidence for this recommendation right now is mainly anecdotal and needs to be studied.

Some animal studies suggest that nightshades could have negative effects in people with IBD, but more research is needed in humans before recommendations to eliminate nightshades can be made.

Other groups of people without autoimmune conditions claim that eliminating nightshades has dramatically improved their health. These people are often said to have sensitivities to nightshades. One of these groups includes people with arthritis, as some claim that eliminating nightshades provides pain relief. It is true that a vitamin D-like substance was discovered in plants in the nightshade family. And some studies have reported that animals feeding on these plants have developed calcium deposits in soft tissues, which cause health problems 19 , 20 , In addition to nightshade sensitivities, in rare cases, some people have allergies to specific nightshade vegetables.

Symptoms of an allergy vary but can include skin rashes, hives, itching in the throat, swelling, and difficulty breathing 22 , If you experience any of these symptoms when you eat a particular nightshade vegetable, it would be wise to stop eating that particular food and seek medical advice for further testing. Others have rare allergies to nightshades. On the other hand, if you have an autoimmune condition like IBD or think you may be sensitive to nightshades, you might want to consider removing them from your diet to evaluate changes in symptoms.

If you decide to do this, completely eliminate all nightshades and products containing these vegetables for at least 4 weeks. Be sure to keep track of the severity of your symptoms during this time.

After this elimination period, you should start reintroducing nightshade vegetables one at a time back into your diet. After reintroducing nightshades, compare the severity of your symptoms during your elimination and reintroduction periods. All of these plants contain alkaloids with varying levels of toxicity. Members of the nightshade family produce several different toxins, called alkaloids, that are dangerous to humans, pets and livestock. In vegetables, the primary toxin is solanine, which is concentrated foliage and found in trace amounts in the fruit.

High levels are also found in the green skins of sun-scalded potatoes. Peeling off green potato skins removes the toxins, but many people prefer to discard green potatoes. Another alkaloid found in nightshades is nicotine. It is present in small amounts in vegetables such as eggplants and tomatoes, and in greater concentrations in nightshades that are members of the Nicotiana genus, such as tobacco. Vegetable nightshades include white and red potatoes, tomatoes, sweet and hot peppers and eggplants.

Nightshade vegetables are part of the plant family Solanaceae. Some species are toxic, including the belladonna plant, which is also called deadly nightshade.

Other species are commonly cultivated and eaten by humans. Solanine is found in trace amounts in potatoes and is normally safe, though the leafy stalks of the potato plant and green potatoes are toxic, and solanine poisoning has been reported from eating green potatoes.

Certain nightshade vegetables can be excellent sources of nutrients, including vitamins , protein, and fiber. Eggplant is an ingredient used in many diets, including the Mediterranean diet and is stocked in most grocery stores.

Eggplant is a good source of fiber, potassium , and vitamin B-1, B-6, and K. Tomatoes are an excellent source of vitamins and minerals, including biotin , potassium, iron, and zinc. They also contain the antioxidant lycopene, which may improve inflammation. Purple, white, and yellow potatoes all offer nutritional value that includes fiber, vitamin C and vitamin B Bell peppers are great sources of vitamin A and C, potassium, and folic acid.

According to the Arthritis Foundation , there is no specific diet that a person with rheumatoid arthritis should follow, but there are some foods that can help to control inflammation. Many of these foods are found in the Mediterranean diet. Incorporating these foods into recipes and daily meals is easy with a wide range of recipes available online and in cookbooks. A person may be allergic to one or more nightshade vegetables if they experience the following symptoms shortly after eating them:.
