I have heard that eating foods high in Nitrilosides(vitamin B17) greatly improves sickle cell. Nitrilosides are transformed in the body to thiocyanate which prevents blood from sicklings. You should cut back on foods that are bad for you espiecially fast foods if you want the change in diet to do any good. I will definitely try this out. I found a site that lists many of these foods high in vitamin B17.
