Potassium minimum for healthy bodies

DanielJudysson

I can't find what I need as a minimum for potassium, but I think that is because for healthy people they just set the RDA or AI (the adequate intake) at the need for those who need the most potassium and don't worry about healthy people getting too much from food. This is what I did find out and my link to the very long, detailed article:

Potassium RDA has been set at 4700 mg based on the needs of African-American men on a high sodium diet. As long as potassium is from food rather than pills, no evidence is available that too much potassium is a problem in healthy people - the healthy body will excrete what it doesn't need. But other adults, such as those that restrict sodium to healthy levels, don't need 4700. And those with unhealthy kidney function or other issues will need to restrict sodium and potassium to minimums.

I also read on the Mayo Clinic website that 1600 to 2000 mg is suspected as adequate for most of us. My relative's nutritionist from UCSF set her maximum at 2000 mg because she has kidney disease. So, 2000 mg must be adequate for her. But I'd still like to know what the minimum is. I'll be asking the nutritionist when I go to UCSF with my relative for her next series of appointments.
