FDA RDIs are useful as an average guideline imo, while individual acceptable limits can vary. 2300 mg/day (https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/cfr...) Sodium is not that hard to exceed when consuming processed foods:

1. One serving of TGI Friday fries is 33% of daily sodium intake: https://www.famnom.com/my_food/8eaaea4d-e97d-4a38-8125-4b923...

2. One cheese pizza slice is 28%: https://www.famnom.com/my_food/485759ea-8507-4af7-9efe-bf61b...

Eat food, not too much, mostly unprocessed foods.
