Is Canned Tuna Good for KidneysCanned tuna is the favorite of many people because it contains high-quality protein and low fat. It also contains other essential nutrients, including omega-3 fatty acids -- a type of fat beneficial for cardiovascular health -- and vitamin B-12, a nutrient essential to red blood cell growth. It will be good choice for healthy people. However, consuming canned tuna also comes with some risk, since the fish may contain additives or contaminants that are bad for your kidney health.

- Sodium

Canned tuna often contains added salt to enhance flavor, and regularly consuming tuna can significantly boost your salt intake. A 6-ounce portion of canned tuna contains 420mg of sodium -- 28 percent of your daily adequate intake. High-sodium foods cause your blood vessels to constrict and triggers fluid retention, ultimately raising your blood pressure. A high-sodium diet also puts you at risk of hypertension, which contributes to heart and kidney disease.

In that case, you can choose canned tuna whose brands marked “No Salt Added”. Fresh tuna is also a lower-sodium option -- each 6-ounce serving provides just 55mg of sodium.

- Protein

Protein intake is a very important for people, especially kidney disease patients. Those who have proteinuria are not allowed to take two many proteins. A single can of white tuna, which contains 30 to 40 g of protein, will therefore increase the amount of albumin circulating in your blood. The typical protein requirements are not great --- 56 g for men and 46 g for women. For kidney disease patients who have proteinuria, they are restricted to take 0.6-0.8g protein/kg/ each day.

To sum up, canned tuna have both benefits and side effects. If it is also your favorite, you should be very careful about the dosage. You can gain live support from our experts online.
