5 Miso Health Benefits for Gut Health, Energy, and More

When you hear the word miso, soup might be the first word that comes to mind. And it makes sense—miso soup is delicious, and a common staple at sushi bars and Asian fusion restaurants here in the U.S.. But miso is so rich in flavor (and health benefits) that it's well-worth adding into other parts of your diet, pronto.

The word miso translates to "fermented beans" in Japanese. Makes sense, because it's made from fermented soybeans and grains, which can then be used in everything from veggie dishes, marinades, dressings, glazes, and, yes, soups. Miso reportedly originated from China and was introduced to Japan over 1,300 years ago. At the time, it was used to help preserve food, but its rich umami flavor—a balance of salty, earthy, and a tiny bit sweet—was so good that it quickly started being used as an ingredient in its own right. Originally, only the elite had access to miso, but now it's widely available and easy to find.

Miso health benefits every healthy eater should know

1. Miso is rich in probiotics

The fact that miso is a fermented food probably tipped you off to this one. "One reason fermented foods like miso benefit the gut because is because they contain probiotics," Ingraham says. "Probiotics are helpful live bacteria that are associated with a range of health benefits including reduced inflammation, healthy digestion, and supporting healthy immune system function." While experts generally caution that probiotics and fermented foods alone likely don't have a huge impact on gut health (and there isn't a ton of research specifically linking miso consumption to improved gut health) incorporating foods with miso into a healthy diet filled with other gut-friendly foods (like fiber and plants) definitely can't hurt.

2. It supports the nervous system

"Miso contains a range of B vitamins including vitamin B1 (thiamin), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), and B9 (folate)," Ingraham says, adding that each one benefits the body in different ways. She says that B3, B5, and B9 support the nervous system function properly. Considering that the nervous system controls movement and balance, all five senses, and thought processing in the brain, it's majorly important to get enough.

B vitamins also help provide the body with energy—without enough, you might feel sluggish. "B vitamins are essential for energy production and are involved in reactions of breaking down food into a usable form of energy for the body," Ingraham says. Yet another reason to load up on miso and other foods high in B vitamins.

"B vitamins are water soluble, meaning they are not stored within the body like fat soluble vitamins are," Ingraham adds. "As such, it is important to get adequate intake of all essential B vitamins since they are not stored within the body."

3. Miso is beneficial for women in early pregnancy

Ingraham says that miso's vitamin B9, aka folate, can especially benefit women in early pregnancy. "[Folate is] important for preventing certain birth defects that affect spinal cord development, known as spina bifida," she says.

4. It's good for your bones

Another nutrient miso is rich in is vitamin K, with 29 microunits per 100 grams (it's recommended to get 90 micrograms a day). "Vitamin K is a fat-soluble vitamin that plays an important role in blood clotting, which is important for healing wounds and cuts, and bone health," Ingraham says. Not getting enough vitamin K could lead to developing osteoporosis, so it's important to get enough.

5. It might be beneficial for cardiovascular health

One study found that consuming miso regularly may help protect against strokes, at least in rats. The caveat to this is that it must be done in conjunction with sticking to a low-salt diet. Another small study of Japanese adults found that regular miso soup consumption was associated with decreased heart rate (but had no clear effects on blood pressure). While more research needs to be done—including larger studies with human participants—it's possible that consuming miso regularly could benefit the cardiovascular system.

Are there any downsides to miso?

It's clear that miso is loaded with health benefits for the entire body. But if you have a soy allergy, steer clear, as miso is made from fermented soy. It is also good to be mindful of your overall salt intake when eating miso, as it can be high in sodium. (Just one tablespoon has over 600 milligrams, which is 26 percent of your daily maximum recommended intake of sodium.)

What to know when buying miso

These days, miso can be found at many grocery stores in the refrigerated section, or at Japanese and Asian specialty markets. You'll notice that there might be multiple different kinds displayed on the shelves—which have slightly different flavor profiles and uses.

"The darker misos—dark red, brown, barley misos—are fermented longer than the light-colored ones," says Ingraham. In general, the darker the color, the more intense the flavor. "The light ones like white and yellow misos may be better for dressings, glazes, and light sauces, while the darker misos are good for heartier dishes like stews and heavier soups," Ingraham says.
