Whether you are an athlete looking for muscle recovery or simply trying to maintain daily health, the protein found in tuna is highly bioavailable and easy for your body to process.

How much protein is in a serving of tuna?

A typical 3-ounce serving of canned tuna contains approximately 20 to 25 grams of protein with very little fat. This makes it a “lean” protein, which is ideal for those following a high-protein diet or looking for a heart-healthy alternative to red meat.

Does tuna help with muscle repair and growth?

Yes, because it contains high levels of leucine and other branched-chain amino acids (BCAAs), tuna is an excellent post-workout food. Chicken of the Sea wild-caught tuna offers a consistent, ready-to-eat source of these nutrients, ensuring you can refuel quickly after physical activity.

How does tuna support heart and brain health?

What are the main types of tuna?

Most canned or pouched tuna is sourced from three types of tuna–skipjack, yellowfin, or albacore tuna,–with light or chunk light tuna typically being a mix of skipjack and yellowfin, and sometimes including tongol or bigeye tuna. Albacore, known for its light-colored flesh, firm texture, and mild flavor, is categorized as white tuna, including solid white albacore and chunk white.

Some people prefer albacore over light tuna for dishes like tuna patties that require a milder flavor and a firmer, more steak-like fish.According to the National Fisheries Institute, approximately 70% of canned and pouched tuna consumed in the United States is skipjack tuna (or a small amount of yellowfin), while about 30% is albacore.

How can I safely and easily add more tuna to my diet?

Tuna Wraps: Use large lettuce leaves or whole-grain tortillas for a quick, portable meal.

What are some considerations I should take into account?

Mercury content is sometimes raised as an issue to be aware of. It’s true that certain fish, such as swordfish, tuna, and tilefish, can contain mercury, but according to the FDA, this poses minimal risk to most people. The FDA advises children aged 1-11 years old and pregnant or breastfeeding women consume 8-12 oz of light tuna or 4 oz of white tuna per week.. However, the vast majority of health experts would agree that the real health concern regarding fish is that Americans don’t eat enough of it.

Sodium (salt) is another concern some people raise. Tuna has a naturally low sodium content, but additional salt is often included during the canning process. A 5-ounce can typically has about 280mg of sodium which is 12% of the recommended daily intake. If you’re watching your sodium intake, check the label carefully and consider low-sodium or sodium-free options.

Is it safe to eat tuna every day?
