grz, thank you so much for your time and educating us in what may be the essence of many people problems. so many of us are on various diets, hoping that they will help in some ways, but NPN issue is of the utmost importance. unfortunately an avarage person is not educated in this field and does not know it. C has orthodox medical education and he misleads and confuses the truth. he should retire from CZ and stop spreading his semi educated pulp.
