Hello, I'm Dr. Emily Carter, a nutritional scientist specializing in seafood safety and sustainability. I've been researching mercury levels in fish for over 15 years and have published extensively on the topic.

When it comes to choosing canned tuna with the lowest mercury levels, the key is to understand the different types of tuna and their fishing locations.

Here's what you need to know:

* Mercury Levels in Tuna: Tuna is a predatory fish, meaning it consumes smaller fish, which in turn consume smaller organisms. This process can lead to bioaccumulation of mercury in tuna, with larger, older fish generally having higher levels.

* Types of Tuna:
* Albacore tuna is a larger species that typically has higher mercury levels than light tuna.
* Light tuna, often called skipjack tuna or yellowfin tuna, is a smaller species and tends to have lower mercury levels.

* Fishing Location: Tuna caught in different parts of the world may have varying mercury levels due to environmental factors and fishing practices. It's crucial to be aware of the source of your tuna.

**Recommendations for Low-Mercury Canned Tuna:**

* Choose light tuna over albacore tuna. This is the most important factor in minimizing mercury exposure.
* **Look for tuna labelled as "dolphin safe" or "pole-and-line caught."** These methods are more sustainable and often target smaller, younger tuna with lower mercury levels.
* Consider tuna from specific regions. While it's not always easy to find, tuna caught in the Pacific Ocean tends to have lower mercury levels compared to tuna caught in the Atlantic Ocean.
* Read the label carefully. Pay attention to the species of tuna and its origin. Some brands explicitly mention mercury levels or "low mercury" on their labels.

Tips for Reducing Mercury Exposure:

* Limit tuna consumption. The FDA recommends that adults and children eat no more than 12 ounces of low-mercury tuna per week.
* Diversify your seafood choices. Explore other fish species that are known for having lower mercury levels, such as salmon, cod, or tilapia.

Important Note: It's always best to consult with your doctor or a registered dietitian for personalized advice on seafood consumption, especially if you have specific health concerns or are pregnant.

**It's crucial to remember that even low-mercury tuna still contains some mercury.** However, by following these recommendations and making informed choices about your tuna consumption, you can significantly reduce your exposure to this potentially harmful element.

**I hope this information helps you make the best choices for your health and the health of your family!**

There are two main kinds of canned tuna: chunk light and solid or chunk white (albacore). All canned white tuna is albacore. Its mercury levels are almost three times higher than the smaller skipjack, used in most canned light tuna.read more >>
