One such health problem is inflammatory bowel disease or IBD. This is an autoimmune disorder that mainly involves the irritation and swelling of the digestive tract. The protective coating or lining of the intestine isn’t functioning properly for an individual affected by IBD. Thus, bacteria can easily permeate the bloodstream.

With bacteria infecting the bloodstream, the immune system works by attacking it but worsens the inflammation. It also leads to adverse symptoms in the gastrointestinal area such as malabsorption, diarrhea, and pain.

So, what does the alkaloid content in nightshades have to with IBD? According to tests done on mice, the alkaloid content may aggravate the lining of the intestines further, especially for individuals with IBD. Nonetheless, studies conducted on humans should be done for a definite recommendation.
