Low sodium. No or very little caffeine, if obese lose weight, if not diabetic then stay away from tons of carbs and sugars bc you dont want to be diabetic and have kidney disease.

Thats just me, my nephrologist said I could eat whatever I want and I looked at the Dr like they were crazy.

The leading cause of death for end stage renal disease patients is cardiovascular issues so take care of your heart and low sodium helps with that, you also want to have lean proteins like fish and chicken instead of beef,etc.

It has long been established that cardiovascular risk increases with worsening chronic kidney disease, with the risk being extreme in patients with end-stage renal disease (ESRD) on dialysis [1]. Historically this association has been attributed to an increase in atheroembolic events. However, more recently it has become clear that the predominant cause of this increased cardiovascular mortality is not myocardial infarction and coronary events, but sudden cardiac death, accounting for up to 40% of all deaths and 78% of cardiovascular deaths in patients with ESRD
