Tuna is a saltwater fish used in many dishes, including salads, burgers, steaks, and entrées. It is a good source of protein and healthy fats, making it a popular choice for those on the keto diet. The ketogenic diet is a low-carbohydrate method of eating, and tuna is known to be low in carbohydrates, with almost no sugar or fibre. It is also a good source of omega-3 fatty acids, which are beneficial for heart health and reducing inflammation in the body. While tuna is generally considered keto-friendly, it is important to be mindful of portion sizes and the type of tuna consumed, as some brands may add sugar or use low-quality oil.

What You'll Learn
Tuna is keto-friendly
Tuna is a nutrient-dense food, packed with healthy fats like omega-3 fatty acids, which have anti-inflammatory properties and are beneficial for heart health. It is also a good source of fatty acids EPA, DHA, and ALA, which are essential for the body as it cannot produce them on its own. Additionally, tuna provides selenium, vitamin D, and zinc, which are all important for a healthy immune system.
Canned tuna, a common and affordable option, is typically low in carbohydrates and sugar. For example, one 2-ounce serving of canned chunky light tuna has less than 1 gram of carbohydrates and 1 gram of fat, while providing 10 grams of protein. However, it's important to be mindful of brands that might add a small amount of sugar, although this is usually too low to be a concern for keto dieters.
When incorporating tuna into your keto diet, you can make a quick and easy tuna salad by combining tuna, mayonnaise, dried onion flakes, salt, and pepper to taste. You can serve it with lettuce to keep it keto-friendly, or with bread if you're not concerned about carbohydrates. Another option is to simply drain the canned tuna, mix in some low-carb vegetables, and dress it with olive oil to create a keto-friendly tuna dish.

On average, a 5-ounce can of tuna in water has 120 calories, while a 5-ounce can of tuna in oil has about 280 calories.
Canned tuna is also a good source of several vitamins and minerals, especially vitamin D, selenium, and iodine. It is also a source of minerals such as calcium, potassium, and iron, and vitamins A, D, and B-12. The types and amounts of fats can vary depending on the type of canned tuna you choose, so it is important to read the labels if you want to compare brands.
Tuna is considered a nutrient-dense food. It is also a great source of healthy brain-boosting fats like omega-3s and all three important types of fatty acids: EPA, DHA, and ALA. These fatty acids are important for the immune, endocrine, pulmonary, and cardiovascular systems.

Mercury levels in tuna
Tuna is a popular and nutritious saltwater fish with high protein content and healthy fats and vitamins. However, it may contain high levels of mercury, which has raised concerns among consumers and health experts. Mercury accumulates in the tissues of fish over time and, similarly, can build up in the human body. High levels of mercury exposure may lead to brain cell death and impaired fine motor skills, memory, focus, and sleep. It is also linked to a higher risk of heart disease.
Tuna occupies a top position in the food chain, which means it can accumulate high levels of mercury due to its diet of smaller, mercury-contaminated fish. While the nutrient profile of tuna makes it a desirable food, it is recommended that it be consumed in moderation, especially by certain vulnerable populations. These vulnerable groups include infants, young children, and women who are pregnant, breastfeeding, or planning to become pregnant. The developing brains and nervous systems of infants and unborn babies are particularly vulnerable to the harmful effects of mercury.
The FDA recommends that adults consume 3–5 ounces (85–140 grams) of fish 2–3 times a week to obtain sufficient omega-3 fatty acids and other nutrients. However, research indicates that regularly eating fish with a mercury concentration greater than 0.3 ppm may increase blood mercury levels and pose health risks. Vulnerable groups should adhere to stricter guidelines, with up to 12 ounces (3 servings) of light tuna or 4 ounces (1 serving) of albacore tuna recommended as the weekly limit.
It is worth noting that different varieties of canned tuna have varying levels of mercury, with albacore generally containing more mercury than light tuna. However, unpredictable spikes in mercury content have been observed in individual cans of light tuna, which can change the recommended consumption frequency. Therefore, it is advisable to opt for skipjack or canned light tuna varieties, which have lower mercury levels. Additionally, it is important to include other low-mercury fish, such as cod, crab, salmon, and scallops, in your diet to ensure a varied and safe source of nutrients.

Nutritional concerns
Tuna is a nutrient-dense food that is keto-friendly. It is a good source of protein and healthy fats, making it a perfect snack or meal for individuals following the keto diet. The ketogenic diet is a low-carbohydrate method of eating, and tuna contains almost zero carbohydrates. It is also a good source of omega-3 fatty acids, which are essential for a healthy brain and heart.
However, it is important to consider the nutritional concerns associated with including tuna in your keto diet. Firstly, while tuna is a convenient and affordable option, it has a low amount of fiber, which may make it less filling. To enhance satiety and nutritional value, it is recommended to bulk up your tuna dish with low-carb vegetables, such as leafy greens like kale or spinach.
Another concern is the level of mercury found in tuna. While most health experts advise that the mercury levels are too low to be a concern for most people, it is still important to be mindful of this aspect, especially if tuna is a regular part of your diet.
Additionally, when purchasing canned tuna, it is advisable to choose tuna canned in water or a high-quality oil like olive oil. Tuna canned in vegetable oil or low-quality oils should be avoided due to potential health concerns and inferior taste and texture.
Furthermore, while tuna is a good source of protein, it is important to be mindful of portion sizes. Just because you are following a keto diet does not mean you can overeat. Practicing portion control is crucial for maintaining a healthy balance, even when consuming keto-approved foods like tuna.
