Is Sushi Healthy? Nutritionists Weigh In
White rice is a refined grain, which means the fibrous bran and germ layers have been polished away, leaving only the white middle layer. This process removes some of the nutrients, meaning you might opt for brown rice sushi if you’re more health-conscious.
“Brown rice is slightly more nutritious than white rice. It has more fiber, B vitamins, and minerals like magnesium and manganese,” says Zibdeh. “Sushi is traditionally made with white rice and I feel that it's perfectly fine to enjoy sushi with white rice. You can eat brown rice in other meals.”
Agyeman agrees. “The nutritionally dense option is brown rice, however, the difference is small enough to where people should choose the rice they prefer based on taste and texture,” she says.
High-sodium sauces
One of the most unhealthy components of a sushi meal is soy sauce. The American Heart Association recommends consuming no more than 2,300 milligrams of sodium each day. According to Harvard Medical School, one tablespoon of soy sauce contains 1,260 mg of sodium. So a single sushi dinner could easily put you over your day’s limit.
“Sushi isn’t sushi without a little soy sauce, and now many rolls are served with additional sauces such as spicy mayo and eel sauce,” says Agyeman. “All sauces consumed in moderate amounts should be fine for a healthy individual, however, some sauces have higher amounts of sodium, and/or added sugar. So if heart health or other health conditions are of concern, opt for low sodium soy sauce, or leave off the sauces.”
A healthier alternative is coconut aminos. “Coconut aminos is a popular soy and gluten-free alternative to soy sauce. It’s made from fermented coconut palm sap and much lower in sodium,” explains Zhu. “The sodium count can still add up quickly so be mindful of the amount you consume—to get the right amount of flavor, try dipping just the fish into the soy sauce and not the rice.”
If flavor is your savior, and you want to take your sushi to the next level, there’s always Wasabi. “Wasabi is low in calories and can add a spicy taste. Slices of ginger are also served with sushi, and these please the palate in between rolls. Plus it has anti-inflammatory benefits,” says Zhu. She also suggests limiting your intake of high-calorie mayonnaise-based creamy sauces, which are found in “spicy” rolls.
Other ways to make sushi healthier
In addition to being aware of sodium-rich sauces and calorific creamy sauces, you can make sushi healthier by avoiding or limiting fried fillings, for example, deep-fried soft-shell crab or tempura veggies.
Agyeman recommends uncomplicating your order. “The most effective way to get the most nutrients out of sushi is to keep it simple. Focus on whole foods such as fish, rice, seaweed, and veggies such as cucumbers and avocado,” she says. “Add-ons like sauces and crunchy toppings are tasty but may add more sodium, and/or sugars.” Nori, the seaweed wrap used in maki rolls, is rich in iodine. A study published in the British Journal of Nutrition found that the iodine in nori can reverse the negative effects of cholesterol intake.
Another way to make sushi healthier is to be mindful of portions. Just like other delicious bite-size foods, it’s easy to eat a lot of sushi without even clocking it. So if you’re health-conscious, only eat as much sushi as you need, and consider some nourishing sides. “Have a smaller portion of sushi and fill your plate with nutritious items like seaweed salad, steamed vegetables, or edamame—all options that contain fiber to help fill you up,” says Zhu. She recommends ordering sashimi (thin cuts of raw fish) to lower your carb intake and increase your protein intake.
