@czsalt64 The 3000 mg sodium limit is the old (2018) recommendation for Stage Three CKD. The latest I have heard (as of August 2021) is 1500 mg or less for Stage Four CKD patients. Some kidney websites quote different amounts but what works for me personally is between 1500 and 2000 mg Na daily (including what occurs naturally in whole foods as well as - carefully used - processed foods.) If I am especially active and weather is hot, causing increased sodium loss through perspiration, I can tolerate the higher value. In such a case of perspiration loss of Na, the kidney is not called upon to excrete that which is lost through perspiration, therefore I am comfortable with a slight increase. However, I do not personally recommend ANY values, I merely share what my research shows the experts are saying and I share my own personal experience. Oh, please forgive me for a terrible pun, LOL, but we should take everything with a grain of salt. (Sorry, couldn't help myself.)
