like Jalima, I agree with bags when she questions how much diet influences our health. It goes without saying that healthy diet (so far as we understand that to be on current thinking) has to be better for us than a diet of pies, pasties and cakes, supplemented by a ready supply of pizza and cake. I have been fortunate to have had three consultant rheumatologists over many years. My current consultant has been 'looking after ' me for 15 years. Without exception, they and the specialist nurses who work with them have taken the same view on diet. Yes, eat a healthy, varied diet, keep fats to a minimum, if you find certain foods cause a flare in symptoms, its probably wise to avoid them. They say there is no evidence that giving up e.g. tomatoes, oranges , the kind of foods that have long been seen as triggers, unless of course, you find they trigger a flare up in you.
I know that if I eat too much red meat, any food from a chinese restaurant, even a small glass of red, I'll flare. A glass of white seems to be fine and I'm careful not to overdo that.
Obi - there is no evidence that stress causes auto immune diseases. Yes, stress can exacerbate symptoms, as can getting over tired or over doing most things,sadly. I had an excellent consultant, who took a detailed family and individual health history. My conditions are all based on my genetic makeup and the unfortunate fact that I had glandular fever as a young woman. He said it was all sitting, waiting and that the GF flattened my immune system and allowed it / them in. I'd much rather be informed by these experts than by someone who says everyone she knows who has these conditions has had stress. Haven't we all had stress, but not everyone is unfortunate enough to develop chronic health problems as a result.
