If managing hypertension, what primary nutritional factor in canned sardines requires particular attention?
Answer
Sodium
While sardines offer immense nutritional benefits, the canning process itself introduces a critical consideration for specific dietary needs, namely sodium content. Canned varieties, especially those preserved in brine or various flavorings, can introduce significant amounts of sodium into a single serving, potentially accounting for a large fraction of the recommended daily sodium limit. For individuals actively managing hypertension, or high blood pressure, this high sodium load must be closely monitored and managed, often by choosing packing liquids like water or high-quality olive oil instead of salty marinades.
