Nightshade Vegetables Cause Inflammation

Nightshade vegetables are inflammatory in nature.  

Vegetables in the nightshade family include eggplant, tomato, potatoes and all peppers. Incidentally, Goji berries, gooseberries, and ashwagandha are not true nightshades but still present many of the same problems. In the same way that nightshade vegetables have alkaloids present so do these types of foods and herbs. For this reason inflammation can be the result.

The nightshade vegetables contain a compound called alkaloids and may interfere with joint repair.  Consequently, inflammation may be caused.

Nightshade vegetables contain a form of vitamin D that is potentially harmful. The U.S. National Library of Medicine advises that an overdose can cause weakness in addition to muscle and bone pain.  Another potential issue is that overconsumption can lead to calcium being leached from bones and deposited in the soft tissues. In fact, with this deposit the stage is set for arthritis. For this reason, anyone with joint problems should consider the elimination of nightshades.

Cholinesterase, a naturally occurring enzyme in our body, has the job of regulating muscle flexibility. Solanine is a poison that is found in green potatoes and interferes with cholinesterase. This can then cause issue with comfortable movement and muscle efficiency.

It is important to be aware as recipes that may include this family of vegetables are plentiful. First and foremost, protect yourself.

Medicine may contain Potato Starch Fillers and edible flowers can be of issue. Belladonna, a homeopathic remedy, must be avoided. Belladonna is known as a deadly nightshade due to the leaves and berries being toxic. Regrettably, a person with nightshade sensitivity may even have issue with licking envelopes as many adhesives contain potato starch.

“74 – 90% of people who ache and hurt, regardless of their diagnosis, have a sensitivity to nightshades” according to the chairman of the Arthritis Nightshades Research Foundation.

  • Dr. Elise, I have a sensitivity to nightshades. When I eat them, I get a migraine within minutes. A friend helped me figure out I needed to stop eating peppers. My mother-in-law a few years later helped me figure out I needed to stop eating potatoes. My father-in-law mentioned tomatoes were also a nightshade like potatoes and peppers. I started researching nightshades and decided to stop eating them. I did so good for a long period of time. I still avoid them as much as I can. Though there are a few menu items (spaghetti, pizza, and lasagna) which are difficult for me to avoid. Thank you for the information. I will be reading the website you linked. ~Adrienne
