When you’re looking at the sodium content of a food, the general rule is as follows:
- 5% DV (daily value) or less of sodium per serving is considered low
- 20% DV or more of sodium per serving is considered high
The FDA considers 140 mg of sodium or less per serving a ‘low’ amount and notes that most adults should try to remain under 1,500 mg per day — particularly those with high blood pressure.
To put this all into perspective, consider that a teaspoon of salt contains about 2,300 mg of sodium — your entire daily value. Fast food restaurants usually use more than this amount in their food products.
