Have you eliminated "Nightshade" Vegetables from your Diet?

I came across an article in which Dr. Michael Klaper addresses questions regarding the link between certain foods and joint pain.  I saw online where a woman posted that she had eliminated nightshade vegetables from her diet and noticed significant less amount of pain in her joints. I found this article to be very interesting. My mom suffers from a great deal of joint pain and I passed it along to her, but I wanted to share it with all of you as well!

Have any of you tried this? or eliminated something from your diet and noticed a difference in your  joint pain? I would love to hear from you!

Hope you found this article as interesting as I did.
