How to Make Miso Soup

Recipe From Dr. Mercola

If you’re a Japanese food enthusiast, you might be familiar with their focus on umami, or the “fifth” taste. A very popular source of umami is miso. This is one of the most utilized ingredients in Japanese cuisine, and is the main ingredient for miso soup, a staple in most Japanese households and restaurants.1

But aside from miso soup’s flavor, it is also an impressive source of nutrients and probiotics. Continue reading this article to learn about the benefits you can get from it, and how you can make this soup at home.

What Is Miso Soup?

Miso, or fermented soybeans, is well-loved in Japanese cuisine because of its versatility. For hundreds of years, it’s been used to flavor sauces, marinades and dressings. However, its most popular use is in miso soup.2

But what is in miso soup? To put it simply, miso soup is the classic mixture of dashi — a soup base made with kelp or dried fish — and miso.3 This soup is extremely popular because of its hearty and comforting flavor, which may complement a variety of dishes. Traditional miso soup recipes usually incorporate finely chopped spring onions and firm tofu — however, I recommend that you leave out the tofu to minimize possible exposure to lectins and other harmful materials that accompany unfermented soybeans.

While miso soup’s taste may be enough to make people love it, it is not the only thing to appreciate about it. Because of the fermentation process that miso goes through, the nutritional benefits of this soup are doubled. In fact, miso soup is loaded with numerous vitamins and minerals, together with its probiotic properties.4
