I was just recently diagnosed with MDS and have done a great deal of research. It appears that diet has a tremendous effect on prognosis / outcome. This would tend to indicate why your husband’s bloodwork is worse when his diet is not controlled. I recommend that you read “Beating Cancer with Nutrition”, by Patrick Quillin. I have started following much of his advice about a plant-based diet and have eliminated red meat and am eating large quantities of fresh fruits and vegetables. Additionally, sugar tends to feed cancer cells so I have eliminated most sugar from my diet also. I used to drink a glass or two of white wine with dinner and eliminated that also after reading about the effect of alcohol consumption on blood counts. Just some thoughts. Best of luck.
