How many sushi rolls are considered healthy?

According to nutritionists, one or two rolls would be enough to have a healthy meal. The typical sushi contains white rice, so eating more than the recommended amount can spike your blood sugar.

Keep in mind to order fish and vegetable rolls to stay within a healthier range. It would also be best to be mindful of your condiment consumption. Dipping sauces can add calories and unnecessary sodium, so it’s best to stay away.

Fancy, western-inspired rolls such as Philadelphia or Vegas contain cream cheese and fried fillings, so having two rolls is too much. Half a roll would be best, or stay away from them altogether.

What will happen if I overeat sushi?

What will happen if I overeat sushi

Some sushi lovers may wonder why they need to limit their consumption when the ingredients seem healthy. While veggies, fish, and rice offer health benefits, eating beyond the recommended amount can also be harmful to your health.

Here’s what will happen if you overeat sushi.

1. It can cause blood sugar spikes.

Rice, in general, ranks high on the glycemic index due to its high carbohydrate content. Glycemic Index or GI is a system that ranks the effect of food on a person’s blood sugar.

Like rice, food on the top of the glycemic index scale can cause elevated blood sugar levels, leading to crashes and constant hunger.

2. It can lead to parasitic infections.

Most sushi chefs take extra precautions when preparing raw fish, making parasitic infections rare. However, consuming vast amounts of sushi regularly can increase the chances of contracting this rare disease.

3. It can cause the accumulation of mercury in the body.

According to research, eating much high-mercury fish can damage the central nervous system. It can also be toxic to the kidney, liver, brain, and heart.

Consuming low levels of this chemical through fish dishes, such as sushi can cause headaches, fatigue, and sleep disturbances. Mercury found in seafood is very sticky and stays in the body for a long time when consumed.

Fish like big eye tuna, marlin, swordfish, and king mackerel have high levels of mercury, so it’s best to stay away from them.

Who should avoid eating sushi?

The following people are also discouraged from eating sushi made with raw fish.

  • Children under five years old
  • Seniors over 65 years old
  • Persons who are prone to foodborne diseases
  • People who are taking immunosuppressant medicines
  • Those who are immunocompromised
  • People who have hemochromatosis, a condition of having high iron levels in the blood

Salmon is a popular choice among health enthusiasts since it contains many health benefits. It’s a rich source of healthy fats, protein, vitamin B12, and selenium. Meanwhile, avocado contains magnesium, vitamin C, vitamin E, folate, and fiber.

Consuming salmon at least once a week can help increase good cholesterol or LDL levels and reduce triglyceride levels.

On the other hand, avocado can also help decrease LDL levels and give the body an overall nutrient boost. You can request a brown rice version for a healthier lunch or dinner.


Sushi is so delicious that it’s tempting to eat it as often as possible. However, no one can function on sushi alone. Doctors and nutritionists highly recommend a well-balanced diet composed of various food.
