According to a 2010 study published in *Biology Letters*, mercury levels are actually lower in bluefin toro, or fatty tuna, compared to its leaner counterpart, akami. This surprising finding challenges the common assumption that all bluefin tuna cuts are equally high in mercury and provides valuable context for consumers.

Toro, the prized fatty belly of bluefin tuna, is renowned for its buttery texture and rich flavor, but it is also a source of abundant omega-3 fatty acids, which are vital for heart and brain health. However, as with most large predatory fish, its consumption comes with considerations, particularly regarding mercury levels.

The prized, melt-in-your-mouth experience of high-end sushi is largely thanks to one specific cut. The fattiest part of a tuna is the belly, known as 'toro,' particularly the innermost portion called 'otoro,' which is celebrated for its extreme marbling and delicate flavor.

The most coveted part of a bluefin tuna, especially for sushi enthusiasts, is the fatty belly section known as 'toro'. The pinnacle of this delicacy, called otoro, is the fattiest cut of tuna, celebrated for its exceptional marbling and unparalleled melt-in-your-mouth texture. This richness is why it commands the highest price at elite sushi establishments.

While a single bluefin tuna once sold for a record $3 million at a Japanese auction, the choice between eating bluefin or yellowfin tuna goes far beyond price, involving significant differences in flavor, texture, and conservation status.

According to the U.S. Food and Drug Administration (FDA), mercury levels vary significantly among tuna species, with larger, longer-living fish accumulating the most mercury over their lifespan. This guide will detail exactly what tuna has the highest amount of mercury and provide practical advice for making informed and healthier choices when selecting seafood.

While some species of tuna are indeed fatty, the vast majority of tuna consumed—especially canned varieties—is surprisingly lean. The classification of tuna as a fatty fish depends heavily on the specific type and cut, leading to widespread confusion among consumers.

A fatty cut of bluefin tuna belly, known as otoro, can contain significantly more calories than a leaner cut due to its high concentration of healthy omega-3 fats. Determining the calorie count for "blue sushi" is not straightforward, as it depends heavily on the specific cut of fish and the preparation method, from simple sashimi to ingredient-heavy rolls.

According to the National Oceanic and Atmospheric Administration (NOAA), a 100-gram serving of raw Bluefin tuna contains approximately 23.33 grams of high-quality protein. This makes Bluefin tuna steak an exceptionally dense source of lean protein, popular among athletes and health enthusiasts.

According to nutritional data, a 3.5-ounce (100g) serving of fresh tuna can contain over 30 grams of protein, establishing it as a highly potent protein source. For those tracking their intake, knowing which tuna has the highest protein among the many varieties, and how factors like canning and cooking affect content, is crucial for optimizing a high-protein diet.
