Tuna is a nutritious food choice that is low in calories yet high in protein, making it ideal for muscle building and recovery. Rich in selenium, it not only supports muscle growth but also contributes to overall health and well-being. Incorporating tuna into your diet can help you maintain a balanced nutritional profile while achieving your fitness goals.
How can tuna help with muscle building?
Tuna is an excellent food choice for muscle building due to its high protein content and essential nutrients. Incorporating tuna into your diet can support muscle growth and recovery, making it a staple for athletes and fitness enthusiasts.
High protein content
Tuna is renowned for its high protein content, with a typical serving providing around 20-25 grams of protein. This makes it an ideal option for those looking to increase their protein intake without consuming excessive calories. For muscle building, aim for a daily protein intake of approximately 1.6 to 2.2 grams per kilogram of body weight, and tuna can significantly contribute to meeting this goal.
Rich in essential amino acids
Tuna contains all nine essential amino acids, which are crucial for muscle repair and growth. These amino acids help in synthesizing new muscle proteins, making tuna a complete protein source. Including tuna in your meals can ensure that your body receives the necessary building blocks for effective muscle development.
Supports recovery and growth
The nutrients in tuna, including selenium and omega-3 fatty acids, play a vital role in muscle recovery and growth. Selenium is an antioxidant that helps reduce inflammation and oxidative stress, which can enhance recovery after intense workouts. Additionally, omega-3 fatty acids may improve muscle protein synthesis, further supporting muscle growth.
What are the calorie benefits of tuna?
Tuna is a low-calorie food that provides substantial nutritional benefits, particularly for those looking to maintain or lose weight. With its high protein content and low fat, it serves as an excellent option for muscle building while keeping calorie intake in check.
Low in calories
Tuna is recognized for being low in calories, making it a popular choice for health-conscious individuals. A standard serving of canned tuna in water typically contains around 100 to 200 calories, depending on the variety and preparation method.
This low-calorie profile allows for easy incorporation into various meals without significantly increasing overall caloric intake. For example, adding tuna to salads or sandwiches can enhance flavor and nutrition while keeping calories minimal.
Weight management aid
Incorporating tuna into your diet can aid in weight management due to its high protein content, which promotes satiety. Consuming protein-rich foods like tuna can help curb hunger, making it easier to stick to a healthy eating plan.
Additionally, the muscle-building properties of tuna can support an active lifestyle, helping to maintain lean body mass during weight loss. To maximize these benefits, consider pairing tuna with fiber-rich vegetables or whole grains for balanced meals that keep you full longer.
How does tuna provide selenium?
Tuna is an excellent source of selenium, a vital trace mineral that plays a crucial role in various bodily functions. Consuming tuna can help meet daily selenium requirements, supporting overall health and well-being.
High selenium levels
Tuna is known for its high selenium content, often providing more than the daily recommended intake in a single serving. Depending on the type of tuna, a 100-gram portion can contain anywhere from 60 to 90 micrograms of selenium, which is significant considering the recommended daily allowance for adults is around 55 micrograms.
This mineral is essential for various metabolic processes, including thyroid function and DNA synthesis. Regularly including selenium-rich foods like tuna in your diet can help maintain optimal health.
Antioxidant properties
Selenium acts as a powerful antioxidant, helping to combat oxidative stress in the body. By neutralizing free radicals, selenium can reduce the risk of chronic diseases and support immune function.
Incorporating tuna into your meals not only boosts selenium intake but also enhances your body’s ability to fight inflammation and protect against cellular damage. This makes tuna a smart choice for those looking to improve their overall health.
What types of tuna are available in the UK?
In the UK, you can find several types of tuna, each with distinct characteristics and uses. The most common varieties include fresh, canned, and frozen tuna, each offering unique benefits and considerations for consumers.
Fresh tuna
Fresh tuna is typically sold in fillets or steaks and is prized for its rich flavor and firm texture. Varieties like Yellowfin and Bluefin are popular in restaurants and fish markets. When purchasing fresh tuna, look for bright, moist flesh with a mild scent, and avoid any that appears dull or has a strong odor.
Fresh tuna is best consumed shortly after purchase to ensure optimal taste and safety. If you plan to store it, keep it in the coldest part of your refrigerator and consume it within a couple of days.
Canned tuna
Canned tuna is a convenient and affordable option, widely available in supermarkets across the UK. It comes in various forms, including chunk light, solid white, and albacore, often packed in water or oil. When choosing canned tuna, check the label for sustainability certifications, such as the Marine Stewardship Council (MSC) logo.
This type of tuna is versatile and can be used in salads, sandwiches, or casseroles. It generally has a long shelf life, making it a staple for quick meals. However, be mindful of sodium content, as some brands can be quite high in salt.
Frozen tuna
Frozen tuna is another option that retains much of the freshness and flavor of its fresh counterpart. It is often flash-frozen shortly after being caught, which helps preserve its quality. When buying frozen tuna, look for vacuum-sealed packages to ensure freshness and avoid freezer burn.
Frozen tuna can be stored for several months, making it a practical choice for meal planning. Thaw it in the refrigerator for best results, and cook it promptly after defrosting to maintain its quality and safety.
How to choose the best tuna for health?
Choosing the best tuna for health involves selecting options that are both nutritious and environmentally responsible. Focus on sustainable sourcing and low mercury levels to ensure you are making a healthy choice for yourself and the planet.
Look for sustainable sourcing
Sustainable sourcing means choosing tuna that is caught or farmed in ways that do not harm the environment or deplete fish populations. Look for certifications from organizations like the Marine Stewardship Council (MSC) or the Aquaculture Stewardship Council (ASC) on packaging.
Additionally, consider the type of tuna. Species like skipjack and albacore are often more sustainably managed compared to bluefin tuna, which is overfished in many regions. Opting for products labeled as sustainably sourced helps support responsible fishing practices.
Check for low mercury levels
Mercury levels in tuna can vary significantly between species and sources. Generally, smaller tuna like skipjack tend to have lower mercury levels, making them a safer choice for regular consumption. Larger species, such as albacore and bluefin, can accumulate higher mercury levels due to their size and age.
To minimize mercury exposure, limit consumption of higher-mercury tuna to once a week, especially for pregnant women and young children. Always check local advisories for specific recommendations regarding tuna consumption in your area.

How to store tuna properly?
Storing tuna properly is essential to maintain its freshness and prevent spoilage. Whether canned or fresh, following the right storage methods can extend its shelf life and preserve its quality.
Refrigeration tips
For fresh tuna, refrigeration is crucial. Store it in the coldest part of your refrigerator, ideally at temperatures below 4°C (39°F). Use an airtight container or tightly wrap it in plastic wrap to minimize exposure to air, which can lead to oxidation and spoilage.
