Which canned sardine preparation style typically results in significantly higher sodium content?
Answer
Smoked/Salted Varieties
When examining the different preparation styles available for canned sardines, specific methods significantly escalate the sodium contribution per serving. While oil-packed sardines may increase calorie density and tomato sauce versions often increase sodium and sometimes sugar, the Smoked/Salted Varieties are explicitly flagged as having a significantly higher sodium content overall. This is due to the traditional smoking and salting preservation methods used, making them the least advisable choice for someone eating sardines regularly throughout the week without careful label checking.
