A 5 oz StarKist light tuna can in water gives about 90 calories, 20 g of protein, very little fat, and a steady source of omega-3 fats.
If you reach for a can of Starkist tuna, you probably want quick protein without a lot of fuss. Maybe you are counting calories, watching sodium, or just trying to see how this pantry staple fits into your week. Getting clear numbers and safety info helps you use that small can with real confidence.
This breakdown walks through what sits inside a typical Starkist tuna can, how the macros change from water to oil, where mercury fits into the picture, and how often you can enjoy it. You will also see storage tips and simple meal ideas so that can does more than sit in the back of the cupboard.
Can Of Starkist Tuna? Nutrition Details
A standard 5 oz Starkist chunk light tuna can in water delivers about 90 calories and 20 g of protein once drained, with almost no carbohydrates and around half a gram of fat per can based on label data for this product line. Versions packed in oil push the calories closer to 160 per can while keeping protein around 20 g.
Albacore products sit a little higher. A drained 5 oz Starkist chunk white albacore can in water sits near 100 calories and roughly 22 g of protein, while some solid white albacore in water cans reach about 110 calories and 26 g of protein per can. No-salt-added albacore versions can climb to about 130 calories and 30 g protein per drained can, largely because the drained weight is higher and more fish remains in the can.
To give you a fast comparison, here is an overview of several common Starkist styles plus a generic canned light tuna reference point from nutrient data built on USDA FoodData Central figures for light tuna in water.
| Product Style | Approx Calories Per 5 oz Can | Approx Protein Per 5 oz Can |
|---|---|---|
| Starkist Chunk Light In Water | 90 kcal | 20 g |
| Starkist Chunk Light In Water 25% Less Sodium | 90 kcal | 20 g |
| Starkist Chunk Light In Oil | 160 kcal | 20 g |
| Starkist Chunk White Albacore In Water | 100 kcal | 22 g |
| Starkist Solid White Albacore In Water | 110 kcal | 26 g |
| Starkist No-Salt-Added Albacore In Water | 130 kcal | 30 g |
| Generic Light Tuna In Water, 165 g Can (USDA) | ~190 kcal | ~42 g |
Exact figures depend on drained weight, flavor line, and whether the can includes added broth or seasoning. Still, every option in this family gives a dense hit of complete protein for relatively few calories, especially compared with many ready-to-eat meats.
Calories And Macros In A Can Of Starkist Tuna
Most Starkist tuna cans in water land in the same macro pattern. You get a large share of calories from protein, almost none from carbohydrates, and a modest amount from fat. A typical light tuna in water can sits near 90–191 calories with roughly 20–42 g of protein and under 2 g of fat, according to government nutrient tables for canned light tuna in water and brand label data.
This macro layout suits weight loss, muscle maintenance, and higher protein eating styles. One can often gives as much protein as three large eggs or a full serving of chicken breast, yet the calorie load stays low, especially for light tuna in water. For people who struggle to hit protein targets during the day, a single can folded into a quick salad or rice bowl can close that gap without a large meal.
Oil-packed cans trade a higher calorie hit for richer texture and flavor. The oil raises total fat and calories while protein stays close to 20 g per can. That choice may work well for people who prefer a softer mouthfeel or need more energy in a small volume of food.
Vitamins, Minerals, And Omega 3 Fats
A can of Starkist tuna does more than supply protein. Canned light tuna in water carries a useful amount of vitamin B12, vitamin D, niacin, and minerals such as selenium, magnesium, and phosphorus. In USDA-based nutrition data, a 165 g can of light tuna in water can reach around 191 calories with about 42 g protein, along with iron, magnesium, potassium, and a strong dose of selenium.
Selenium stands out because it acts as a trace mineral that helps limit some of the harm from oxidative stress inside the body. Tuna also contributes vitamin D, which plays a role in bone health and immune function, and vitamin B12, which helps keep red blood cell formation and nerve health on track. That mix turns a can of tuna into more than just “protein in a can.” It behaves like a small nutrient package that touches several body systems at once.
On the fat side, the numbers look small per serving, yet those grams bring marine omega-3 fats such as EPA and DHA. Label data for some Starkist chunk light tuna in oil cans list around 160 calories per can with 20 g protein and around 180 mg combined EPA and DHA per serving. Water-packed versions usually carry slightly lower omega-3 numbers yet still add to your weekly intake. That matters if you do not eat many other types of fish.
Is A Can Of Starkist Tuna Safe Every Day
Mercury always comes up when people talk about canned tuna. Light tuna, the kind used in many Starkist chunk light cans, usually comes from smaller species like skipjack. These fish sit lower in the food chain and tend to carry less mercury than larger species such as albacore or bigeye. In the United States, the Food and Drug Administration classifies canned light tuna as a “best choice” fish for many people when eaten in moderate amounts.
The current FDA advice about eating fish suggests that most adults aim for at least two servings of seafood per week and that people who are pregnant, breastfeeding, or feeding young children choose lower-mercury species and stay in the 8–12 ounce per week range for that group. Canned light tuna usually appears on the lower-mercury side of those charts, while albacore and some larger tuna species show up in tighter weekly limits.
For healthy adults who are not pregnant, a can of light Starkist tuna several times per week usually sits inside those ranges, especially when the rest of the week includes other seafood choices. People who rely heavily on albacore or who fall into higher risk groups may want to limit albacore cans, mix in other fish, and talk with a clinician or dietitian if they have questions about long-term intake.
How To Pick The Right Starkist Can For You
When you stand in front of a shelf filled with blue Starkist labels, a few small choices shape what lands in your bowl. Water versus oil changes calories and fat. Sodium levels shift between regular, reduced sodium, and no-salt-added cans. Albacore cans tend to carry slightly higher mercury levels than chunk light cans because they come from larger tuna.
If you watch calories, standard chunk light in water or reduced-sodium chunk light in water makes sense. If you want a richer taste and do not mind more energy from fat, chunk light in oil brings that. When sodium is a concern, labels that read “no salt added” or “25% less sodium” help keep daily totals lower, and rinsing the drained tuna under cold water before mixing can remove a little more. Reading the panel for calories, protein, fat, and sodium per can turns a quick grab into a clear choice.
Searches For “Can Of Starkist Tuna?” And What They Really Mean
People typing “can of starkist tuna?” into a search bar are often not just asking whether the can exists. They want to know if this food fits a meal plan, whether the macros match their goals, and if mercury or sodium should make them pause. Others use the phrase “can of Starkist tuna?” when they are trying to compare this option against canned chicken, fresh fish, or plant-based protein sources.
In practical terms, a can of Starkist tuna works as a flexible protein base. You can stir it into yogurt or a light mayo dressing for a simple salad, pile it onto whole grain toast, mix it with cooked pasta and peas, or fold it into a rice bowl with vegetables and a drizzle of olive oil. Each of these meals builds on that same compact can while shifting the rest of the macros with your add-ins.
Easy Ways To Use A Can Of Tuna
Once you know the numbers, it becomes easier to use Starkist tuna in a way that fits your day. If breakfast was light on protein, a lunch built around one can balances things out. If dinner will be heavier, you can keep the rest of the meal simple with greens and grains while letting the tuna handle the protein side.
Here are a few quick patterns many people like:
- Tuna salad made with plain yogurt, mustard, chopped celery, and herbs, served on whole grain bread or lettuce leaves.
- Warm tuna and tomato pasta with garlic, olive oil, and a handful of spinach tossed in at the end.
- Brown rice or quinoa bowl topped with tuna, cucumber, shredded carrot, and a squeeze of lemon.
- Baked potato or sweet potato split open and filled with tuna, a spoon of plain yogurt, and chives.
Storage, Shelf Life, And Food Safety For Starkist Cans
Unopened Starkist tuna cans store well at room temperature in a cool, dry cupboard. Many carry “best by” dates several years from the packing date. That date speaks to peak flavor and texture, not sudden spoilage the next morning, yet rotating stock so the oldest cans get used first keeps quality high. Cans that are rusted through, badly dented at the seams, leaking, or bulging should be discarded.
Once opened, tuna moves into a short window. Transfer leftovers from the opened can into a clean, covered glass or food-safe plastic container, keep it chilled, and eat within a few days. The table below gives rough storage timelines that many home cooks follow.
| Storage Situation | Time Frame | Simple Tip |
|---|---|---|
| Unopened Can In Pantry | Up To Best-By Date | Keep in a cool, dry, dark spot. |
| Unopened Can In Warm Area | Shorter Than Best-By Date | Avoid spots near the stove or heater. |
| Opened Tuna In Fridge | 3–4 Days | Move to a covered container after opening. |
| Tuna Mixed With Mayo Or Yogurt | 1–3 Days | Keep chilled and discard if smell or texture changes. |
| Frozen Leftover Tuna | Up To 2 Months | Freeze in small, labeled portions for later meals. |
| Can With Bulging Lid Or Leaks | Do Not Use | Throw away; do not taste “to check.” |
| Can With Heavy Rust Or Deep Dents | Do Not Use | When in doubt, discard the can. |
Smell and appearance matter too. Tuna that smells sharply sour, looks dull or oddly colored, or feels slimy after proper storage belongs in the bin, not in a sandwich. When the fish smells clean and the dates are in range, that small can offers a fast, reliable, and nutrient-dense way to bring seafood onto your plate without a trip to the fresh fish counter.
