Hello - I'm Wendy. I work with a research company that is dedicated to solving serious nutritional problems for those who must limit salt (sodium chloride), and/or potassium, and phosphorus. If you are on dialysis (or one of the 1.2 M who are progressing toward it), or if a doctor or dietitian has said dietary mineral reduction is a must, then you know how frustrating it can be to accomplish this and still eat the way you want to.
Before you resign yourself  to limiting or cutting out the foods you love, you need to know that there IS a way to remove these minerals from many foods - before you eat them - so you can continue to eat them. The instructions are simple, and they can be found in a guide book called 'Food - Fuel - Fitness' (2nd Ed.). This guide book is an outgrowth of the research conducted by Royal Knight Incorporated in 1998-2000. A small patient efficacy study was also conducted which was positive.
Some of the data in this book was reported at National Kidney Foundation meetings.

Decide for yourself after browsing if food mineral reduction (demineralization) is right for you.
