My consultant informed me there is no firm evidence that diet can impact on CLL, however I have read that some individuals have been sure changes in diet has helped e.g. No dairy, green tea extract etc. My view is that although there's no firm evidence certain foods can improve or make CLL worse that whilst we don't fully understand the condition anything is possible. I'm a coeliac and years ago nobody would have entertained the idea that eating gluten causes an immune response against the body. Does anyone feel they have had any success through changing diet/ taking supplements? Many thanks.
