"Poisonous" does not mean deadly. Some manifestations of toxicity are subtle. The dose, as always, determines if a plant is safe source of nutrients or a toxic hazard.

BRIEF: Dou you know if solanine can cause joint inflamation?

I have had a problem for the past ten years with Rhumatoid Arthritis and/or Inflamation of the Joints. The symptoms seem to be allergy related. For instance I cannot tolerate potatoe at all, to a lesser degree tomatoe and peppers. Also soy products cause my left knee to swell. Processed meats are also a problem. I have been tested for Rhumatoid Arthritis and the tests showed positive, but, I am not sure how much is also allergy related because when I eat the above mentioned foods the symptoms get much worse. My question is, have you any information that supports solanine causes joint inflamation or affects people with Rhumatoid Arthritis?


I have not heard, nor have I read or seen any cases in which tomatoes, peppers or potatoes caused or aggravated rheumatoid arthritis. I didn't answer this for a long time because, although I once heard tht it could increase symptoms of gout, I have not been able to put my hands on any literature to that effect, or do I remember where I heard it, so it probably is not true. You may have an allergy that manifests itself with joint swelling, or recurring episodes of rheumatoid arthritis may coincide without causality with eating solanaceous plants. Solanine has a lot of bad effects, but i have not read that swollen joints was one of them!
