Caution On Potassium
September 8, 2014
| A version of this story appeared in
Volume 92, Issue 36
Thank you for the article on the Food & Drug Administration’s proposal to revise food labels (C&EN, July 28, page 26).
Inclusion of potassium on such labels is probably a good idea. However, the label should contain a warning that high-potassium foods should be avoided by people with chronic kidney disease. Similar to the possibility of manufacturers hiking vitamin D values artificially to encourage sales, potassium can be escalated as well with preservatives such as potassium sorbate.
