Does anyone have a definitive lists of foods that are good for the lymph system, and particularly foods to avoid. I am early CLL Watch & Wait but the lymph nodes have recently started swelling - but fortunately only temporarily. It got me thinking that after one swells up, something must be acting on it to clear it. I heard that coffee - because of the caffeine - is not good for lymph flow as the caffeine constricts the lymph vessels, leading to flow congestion and therefore higher risk of lymph node swelling. I do like and need my coffee - it helps me get through the fatigue symptoms, so would only be prepared to give it up if certain. An earlier post in this community highlighted the benefits of coffee. Of course i could stop the coffee for a test period to see - but as there are likely a plethora of other foods that help / hinder the lymph flow it would hardly be the definitive scientific experiment. With CLL I think our diet is of utmost importance because we have a range of conditions to deal with: fatigue and energy -lower oxygen levels due to lower red blood counts; foods that can reduce (hopefully) the severity of the night sweats; and of course those that support the lymph system. Other CLL symptoms namely weight loss, high temperatures must also have foods that are needed. Just as important as the foods that help would be foods that are known to impact, or cancel out any improvements. It may even be that some of us don't have certain symptoms of CLL simply because our current diet prevents those effects appearing. I haven't even touched the discussion of the benefits of an organic vs non-organic diet, or supplements. Whilst in W & W mode a lot of us are frustrated that nothing is being done, however the diet is surely the most important treatment we could have.
