Consumer tips
- 1
Order sushi with brown rice or request 'light rice' to reduce the carb load.
- 2
Choose salmon over tuna for sashimi to lower your mercury exposure.
- 3
Dip your fish lightly in soy sauce—most of the sodium comes from over-dipping.
- 4
Ask for ginger on the side to cleanse your palate instead of loading up on salty sauces.
