Just follow a good healthful nutrition plan. Since we donors have a tendency to develop high blood pressure it is especially wise to follow the recommendations (such as reduced sodium) that anyone should follow in order to decrease the risk. I have read that the fruit known as "star fruit" can be kidney toxic for some. The National Kidney Foundation www.kidney.org
in its "Love Your Kidneys" program sometimes offers healthful recipies (and you can sign up for a free e-mail newsletter) but we don't have to follow the restrictions that those with kidney disease have to follow. Of course no matter what we eat we should maintain a healthy weight, as overweight can contriute to high blood pressure or diabetes. So, eat, drink and enjoy (in moderation).
