Sushi is dangerous!?
Hi, this is Dr.Yuki. What is your favorite food? For me, it is definitely Sushi. I’m eating it right now, actually. But, is it safe for us? Let us think about it.

Japanese sushi is a culinary delight cherished worldwide for its delicate flavors and artistic presentation. However, there’s a hidden concern lurking in some of those beautifully crafted pieces: mercury. Here’s a quick dive into the mercury issues associated with sushi and how you can enjoy this beloved dish safely.
What is Mercury and Why is it a Problem?
Mercury is a heavy metal that can be harmful to human health. In the environment, it can transform into methylmercury, a toxic compound that accumulates in fish. When we consume fish high in mercury, it can lead to mercury poisoning, which affects the nervous system and can be particularly dangerous for pregnant women and young children.
High-Mercury Fish in Sushi
Some fish commonly used in sushi are known to have higher levels of mercury. These include:
- Tuna (especially Bluefin, Bigeye, and Albacore): A popular sushi choice, but often high in mercury.
- Mackerel (especially King Mackerel): Another sushi favorite that can have elevated mercury levels.
Avoid eating too much and enjoy your meals for long time!
