What You'll Learn
Tuna is keto-approved
Tuna is a saltwater fish commonly used in Asian cuisines. It is found in the temperate and subtropical waters of the Atlantic Ocean but is supplied all over the world. There are eight different species of tuna, including bluefin, yellowfin, albacore, and skipjack. It is relatively easy to catch and can be prepared in a variety of ways, including salads, burgers, steaks, and entrees.
Tuna is a nutrient-dense food that provides vitamin D and selenium. Vitamin D helps the body absorb calcium and phosphorus, improving bone strength and reducing the risk of osteoporosis and other bone disorders. Selenium helps preserve protein elastin, which keeps skin tight and smooth. Tuna is also a source of omega-3 fatty acids, which have anti-inflammatory properties and are important for brain health and several body systems, including the immune, endocrine, pulmonary, and cardiovascular systems.
Canned tuna is a convenient and affordable option for those on the keto diet. It is keto-friendly, with almost zero carbohydrates and a good amount of protein. However, some flavored packets may contain added ingredients that increase the carb count, so it is important to check the labels.
When preparing tuna for a keto diet, it is important to focus on low carbs and high fat. This can be achieved by adding healthy fats like olive oil or mayonnaise and pairing the tuna with low-carb vegetables like kale or spinach.

Nutritional benefits of tuna
Tuna is a saltwater fish used in many dishes, including salads, burgers, steaks, and entrees. It is one of the most commonly consumed fish in the world, with canned tuna being particularly popular in the US due to its affordability, versatility, and ease of storage.
Tuna is a nutritious food with many health benefits. It is a great source of protein, providing over 40 grams per 172-gram can. Protein supports satiety by slowing down digestion and increasing hormones that help you feel fuller after eating. Tuna is also low in calories, which can aid in weight loss. In one study, adolescents who regularly ate lean fish like tuna lost an average of two pounds more weight than those who didn't eat fish.
Tuna is also a good source of healthy fats, specifically omega-3 fatty acids, which are beneficial for heart, eye, and brain health. These fatty acids are important for the immune, endocrine, pulmonary, and cardiovascular systems, and they can help lower inflammation in the body. Additionally, tuna contains vitamin D, which helps the body absorb calcium and phosphorus, improving bone health and reducing the risk of osteoporosis and other bone disorders.
While tuna has many nutritional benefits, it is important to consider its potential downsides. Tuna can contain high levels of mercury, so it is recommended that pregnant women and young children consult with a doctor before consuming it. Canned tuna typically has lower mercury levels than fresh tuna due to the smaller fish used for canning. Additionally, due to environmental concerns, it may be advisable to limit tuna intake and choose more environmentally-friendly protein sources, such as sardines or plant-based proteins.

Flavoured tuna packets
Tuna is a versatile, affordable, and keto-friendly food. It is a good source of protein, selenium, vitamin D, and omega-3 fatty acids. While fresh tuna is delicious, canned tuna is a convenient and affordable option that is also suitable for the keto diet.

Another example is the StarKist Tuna Creations range, which offers flavoured tuna packets with various carb counts. The Ranch flavour has around 1 gram of net carbs and 15 grams of protein, while the Ginger Sesame flavour has 8 grams of net carbs, which is higher but still suitable for some keto dieters.
When choosing flavoured tuna packets, it is important to read the labels and check the carb counts, as some brands may add ingredients that increase the carb content. However, these flavoured options provide a convenient and tasty way to include tuna in your keto diet.

Mercury levels in tuna
Tuna is a popular and nutritious saltwater fish that may contain high levels of mercury. As a result, regular tuna consumption may lead to health issues. Mercury contamination in fish, particularly tuna, has raised significant concerns for consumers and health experts. As one of the most widely consumed fish species, tuna can accumulate high levels of mercury due to its position at the top of the food chain. Tuna feed on smaller fish that are already contaminated with varying amounts of mercury.
Mercury in tuna is a health concern because of the risks associated with mercury exposure. Just as mercury builds up in fish tissues over time, it can also accumulate in the human body. To assess how much mercury is in a person's body, a doctor can test mercury concentrations in their hair and blood. High levels of mercury exposure may lead to brain cell death and impaired fine motor skills, memory, focus, and sleep. Mercury buildup is also linked to a higher risk of heart disease.
The FDA recommends that adults eat 3–5 ounces (85–140 grams) of fish 2–3 times a week to get enough omega-3 fatty acids and other beneficial 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. Certain populations are especially susceptible to mercury and should limit or completely avoid tuna. These include infants, young children, pregnant and breastfeeding women, and those planning to become pregnant.
While most health experts recommend including some tuna in your diet due to its low mercury levels, it is important to consume it in moderation. When buying tuna, opt for skipjack or canned light varieties, which have lower mercury levels than albacore or bigeye tuna. Avoid consuming albacore or yellowfin tuna more than once per week and refrain from bigeye tuna as much as possible.
