Is it ok to Have Miso Soup During Pregnancy?

The answer is, yes. It is completely safe to consume miso soup during pregnancy. However, it is necessary to check the label before purchasing. This is because instant miso soup may contain large quantities of salt, which might harm pregnant women.

If you are pregnant and opting for instant miso soup packets, check the following points.

  • Use white miso soup instead of red and brown, which are high in sodium
  • Do not boil the instant miso soup. Boiling the miso soup kills the natural enzymes present in it
  • Try gently warming the soup and removing it from the heat

Ingredients in Miso Soup That Can Be Considered While Pregnant

Though miso soup is entirely safe to consume during pregnancy, it is essential to check its ingredients. There are a variety of miso soups available in the stores.

The following are some of the most commonly used ingredients in miso soup:
