Five Protein-Packed Canned Foods Dietitians Keep in Their Pantries

Skip the Premium Price Tag

Your grocery store's canned food aisle might be the most overlooked protein goldmine in the entire store. Products touting added protein are everywhere–and they're usually accompanied by a premium price tag. But getting more protein in your diet doesn't have to be complicated or expensive. In fact, protein-rich canned foods can be just as convenient as a scoop of protein powder since they are pre-cooked and ready-to-eat.

Many canned foods are a seriously underrated source of protein, and they often provide other important nutrients, too. Dietitians consistently recommend five standout options that deliver impressive protein counts while offering exceptional value and convenience for busy households.

The Top Five Protein Champions

Sardines pack nearly 23 grams of protein per can and are rich in essential EPA and DHA omega-3 fatty acids, which support brain and heart health. Because sardines are found lower on the food chain, they tend to contain less mercury and fewer contaminants than larger fish. That makes sardines a smart seafood choice for people who are pregnant or breastfeeding, as well as children, who need to be especially mindful of mercury exposure.

Canned tuna is a protein powerhouse, boasting over 20 grams of protein per 5-ounce can. It's also a source of omega-3 fatty acids, which support heart health, help reduce inflammation, promote joint health and more. Look for varieties of smaller tuna, which have lower mercury levels. These include skipjack and yellowfin tuna, and may be packaged as 'chunk light' or 'light'.

Just like fresh salmon is an excellent source of omega-3 fatty acids, canned salmon is also a great source, and very affordable. Canned salmon provides about 18 grams of protein per serving. Plus, it's one of the few foods naturally rich in vitamin D, which helps build and maintain strong, healthy bones.

Plant-Based Powerhouses

Canned black beans offer 8 grams of protein per ½ cup. They're also high in fiber, with 9 grams in that ½-cup serving, which is 32% of daily fiber needs. Most bean varieties contain 8 grams per half-cup and are an excellent source of plant-based protein. If you are worried about the sodium content of canned beans, you can simply drain and rinse the beans with water, which can lower the sodium content by up to 40%.

Chicken Chili is an excellent source of protein, typically containing about 20-25 grams of protein per serving (1 cup), depending on the recipe. The chicken provides lean protein, essential for muscle building and repair, while beans (if included) contribute additional plant-based protein. This versatile option combines multiple protein sources in one convenient package.

Smart Shopping Strategy

Compared to fresh foods, the canned versions offer similar amounts of nutrients, including protein, fiber, vitamins and minerals. The canning process actually preserves many nutrients in foods. Produce like vegetables and fruits are harvested at peak ripeness before being sealed in a can, which locks in vitamins and minerals.

These shelf-stable protein sources represent a practical solution for meeting daily nutrition goals without breaking the budget. Protein intake is critical for health, growth and development, weight maintenance, appetite management, satiety and more. By stocking these five canned options, you're building a foundation for quick, nutritious meals that can adapt to any cooking style or dietary preference.
