I recently found that potatoes and tomatoes (nightshade family) give my T a little spike. Hadn't realised this before because they're such common foods but I went for a week without eating any and then ate some home made leek and potato soup... this is when I wondered.. and having tested it since I know that they do spike it. Although the spike is only slight - perhaps, for me, eating potatoes and tomatoes is a bad idea. I switched to sweet potatoes about 5 days ago and they don't have the same effect. Then yesterday cayenne pepper (a lot of it) in home made spicy sweet potato soup made my T go through the roof - I actually threw the cayenne in the bin afterwards. I knew before that tea, sodium nitrate, potassium nitrate, citric acid and acetic acid all affect the volume of my T. I'm finding that I really can control my T by controlling my diet. Before I could only work out what made it go absolutely crazy but now I can see which foods are just making it a 'little louder' (almost like they are feeding the T). Stress still doesn't make any difference to it but certain foods really do.
