What are Nightshade Vegetables

Nightshade vegetables are part of the Solanaceae plant family.  This family is not limited to only vegetables but, flowers, trees and even toxic herbs (atropa belladonna).  The vegetables are still the largest part of the family.

Nightshades have two things they share in common which is the presence of 2 substances:  calcitriol and alkaloids.  Three alkaloids in the nightshade family are Solanine, Capsaicin and Nicotine.

Solanine and Tomatine

Solanine is a steroid alkaloid.  This alkaloid is primarily found in potatoes as well as its tomato counterpart, tomatine.  While not immediately toxic, it stores in the body and may be released during stress which can harm the body.  Solanine can irritate the gastrointestinal system and also affect neurotransmitters.

Capsaicin

Capsaicin is the active ingredient in hot peppers and is most commonly thought of for its anti-inflammatory properties but it is also and alkaloid

 

Nicotine

Nicotine is the substance found in the tobacco plant and is also a nightshade. Nicotine is harmful in many ways to our body however this alkaloid is present in all parts of nightshade vegetables.

 

Allergy and Sensitivity
