Sushi Consumption Frequency?

Well, the only honest answer is, "it depends".

How much sushi do you eat in a meal?

How much can you afford?

Do you eat good healthy food the other days of the week?

The best answer I can give you is that the USDA, the FDA, and the EPA all recommend no more than 1 serving of fish a week. This is based on the fairly high level of toxins and heavy metals found in fish.

Some sushi is worse than others.

the other thing to keep in mind is overfishing. A lot of seafood in a Japanese restaurant are over harvested. SeaFoodWatch.org does a good job of listing the fish that should be avoided based on sustainability.

Or you can do what I do. You can have as much sushi as you want - just make sure it's vegetarian.

It's food, isn't it? How often do YOU eat food in a week? I can eat sushi that often.

Seven days a week.

I hate sushi, so my answer would be "zero"

never.
