Tuna belly, also known as “toro” in Japanese, has long been a topic of debate among seafood enthusiasts and chefs. While some swear by its rich, buttery flavor and velvety texture, others dismiss it as a waste product, only fit for cat food or fertilizer. But is tuna belly really good eating, or is it just a myth perpetuated by sushi aficionados and seafood snobs?
The Anatomy of Tuna Belly
To understand the appeal of tuna belly, it’s essential to know where it comes from and what makes it unique. Tuna belly is the fatty part of the tuna’s abdomen, located near the head and gills. It’s a deposit of fatty tissue that the tuna uses to store energy, similar to the way humans store fat in their bodies.
The tuna belly is composed of a high percentage of fat, which can range from 20% to 50% depending on the species and diet of the tuna. This high fat content gives tuna belly its characteristic rich, buttery flavor and tender texture.
Tuna Belly vs. Other Cuts of Tuna
Compared to other cuts of tuna, such as the loin or the steak, tuna belly is significantly fattier and more tender. The loin, which is the most commonly consumed cut of tuna, is leaner and firmer in texture, with a milder flavor. The steak, which is cut from the middle of the tuna, is also leaner than the belly, but has a slightly sweeter flavor.
| Cut of Tuna | Fat Content | Texture | Flavor |
| — | — | — | — |
| Tuna Belly | 20-50% | Tender, velvety | Rich, buttery |
| Tuna Loin | 5-10% | Firm, lean | Mild, slightly sweet |
| Tuna Steak | 10-20% | Medium-firm | Sweet, slightly nutty |
The Cultural Significance of Tuna Belly
Tuna belly has a long history in Japanese cuisine, where it’s considered a delicacy and a symbol of luxury. In sushi restaurants, tuna belly is often served as sashimi or nigiri, and is prized for its rich, buttery flavor and tender texture.
In other cultures, tuna belly is also valued for its nutritional benefits. In some African countries, tuna belly is considered a staple food and is often served fried or grilled. In the Mediterranean, tuna belly is used to make a variety of dishes, including salads, stews, and pasta sauces.
The Health Benefits of Tuna Belly
Despite its high fat content, tuna belly is a nutritious food that’s rich in protein, omega-3 fatty acids, and various vitamins and minerals. The omega-3 fatty acids in tuna belly have been shown to have numerous health benefits, including reducing inflammation, improving heart health, and supporting brain function.
Tuna belly is also a good source of vitamin D, which is essential for bone health and immune function. Additionally, tuna belly contains a variety of minerals, including selenium, magnesium, and potassium, which are important for maintaining healthy blood pressure, bone health, and muscle function.
The Challenges of Cooking Tuna Belly
While tuna belly is a delicacy in many cultures, it can be challenging to cook. Due to its high fat content, tuna belly is prone to spoilage and can become rancid if not stored properly. Additionally, tuna belly is a delicate fish that requires gentle cooking to prevent it from becoming tough and rubbery.
To cook tuna belly, it’s essential to use a gentle heat and a short cooking time. Grilling, pan-frying, and poaching are all good methods for cooking tuna belly, as they allow for a quick and gentle cooking process.
Tips for Cooking Tuna Belly

The Sustainability of Tuna Belly
While tuna belly is a delicacy in many cultures, its sustainability is a concern. Many species of tuna are overfished, and the fishing methods used to catch them can be destructive to the environment.
To ensure that tuna belly is sustainable, it’s essential to choose a species that’s certified as sustainable by a reputable organization, such as the Marine Stewardship Council (MSC). Additionally, choosing tuna belly that’s been caught using eco-friendly fishing methods, such as pole-and-line or troll fishing, can help to reduce the environmental impact of tuna fishing.
Sustainable Tuna Belly Options
- Bluefin tuna: While bluefin tuna is a highly prized species, it’s also highly overfished. Look for bluefin tuna that’s been certified as sustainable by the MSC.
- Yellowfin tuna: Yellowfin tuna is a more sustainable option than bluefin tuna, and is often certified as sustainable by the MSC.
- Albacore tuna: Albacore tuna is a small species of tuna that’s often caught using eco-friendly fishing methods.

To address these concerns, many organizations and fisheries are promoting sustainable tuna fishing practices, such as pole-and-line fishing and catch-and-release fishing. Consumers can also play a role by choosing sustainably sourced tuna products and supporting eco-labeling initiatives.
Can tuna belly be farmed sustainably?
Yes, tuna belly can be farmed sustainably. Some aquaculture operations are using innovative farming techniques, such as recirculating aquaculture systems (RAS) and offshore farming, to reduce the environmental impact of tuna farming. These systems allow for better control over water quality, feed usage, and waste management, making them more sustainable than traditional farming methods.
Sustainably farmed tuna belly can also help reduce the pressure on wild tuna populations and support the recovery of endangered species.
