Can hemodialysis patients add a little bit of salt to their daily food? How much of salt intake per day is too much if dialysis is done three times a week? Are there any recommendations for salt substitutes if hemodialysis patients had to completely avoid adding salt?
They can if they really 'want to' not the same as needing to.
Most good quality fresh fruit and veg includes enough natural sodium for a healthy diet. For those on heamodialysis off the shelf substitutes such as Lo-Salt are NOT recommended as they are potassium based salts. Not a good thing if your on thrice weekly heamo.
The RDA in many countries is about 1 full teaspoon a day. The main issue with adding salt to food for heamodialysis patients is it makes you thirsty, leading to drinking more, leading to fluid overload with the potential to damage the heart.
Hope this is useful:)
Most kidney cookbooks recommend using herbs, dried or fresh to season and flavour dishes that may seem plain.

Over processed and so called fast foods tend to be high in salt, and much mass produced fresh food may have lower nutritional levels but you should still get adequate salt.
