Canned Tuna Fish: Is It Even Safe For High Blood Pressure? (Expert Answer)
✪ Key Takeaway: Canned tuna can be safe for high blood pressure if you choose low-sodium or no-salt-added varieties and limit portions. Introduction You stand in the grocery aisle staring at rows of canned tuna wondering if this convenient protein will send your blood pressure soaring. You have heard tuna is heart-healthy but you also know that sodium is your enemy when managing high blood pressure. Hi, I am Abdur, your nutrition coach and today I am going to explain exactly how canned tuna affects your blood pressure and which types you can safely enjoy without worry. What Makes Canned Tuna a Blood Pressure Concern? The main problem with canned tuna is not the fish itself but what gets added during processing. Regular canned tuna contains 200 to 400 milligrams of sodium per serving depending on the brand and preparation method. This sodium comes from salt added as a preservative and flavor enhancer during the canning process. When you consume excess sodium your body retains more water to dilute the salt concentration in your bloodstream. This extra fluid increases the volume of blood flowing through your vessels which raises pressure against artery walls. The American Heart Association recommends no more than 1500 milligrams of sodium daily for people with high blood pressure. A single serving of regular canned tuna can take up nearly one-third of your daily sodium limit before you even add it to a sandwich or salad. ✪ Fact: Water-packed tuna typically contains less sodium than oil-packed varieties
