The National Academy of Medicine has halved the adequate intake (AI) for potassium, not due to new evidence of reduced need, but because of a change in DRI guideline methodology that separates deficiency prevention from chronic disease risk reduction.

“the National Academy of Medicine who set formerly the Institute of Medicine who sets the dris which are the RDA and adequate in dictum tolerable upper intake level and stuff like that they just this year put out a new adequate intake for potassium that's about half of what it used to be Wow but but look and that that has nothing to do with better with like new evidence and really has everything to do with into 2017 they came up with new guidelines for how they make the dris and they do them very differently now”
