Crunchy pork rinds (skins) have grown in popularity due to increased interest in the low-carb ketogenic diet. However, though pork rinds are a keto-friendly snack, they’re high in sodium. A 1-ounce (28-gram) serving of pork rinds has 515 mg of sodium, or 22% of the RDI. If you opt for barbecue flavor, a serving has 747 mg of sodium, or 32% of the RDI. If you’re craving something crunchy, consider unsalted nuts instead.
