Read more about miso below, including how you can include it in the diet.

What is it?

This is a type of fermented soybean paste that is popular in Japanese cuisine. It is made by fermenting soybeans with salt and koji (a type of fungus) and sometimes seaweed, rice, and barley.

The fermentation process can take anywhere from a few weeks to years, depending on the type and the desired flavor. 

During this time, the koji breaks down the starches in the rice into sugars, which in turn ferments the soybeans. This fermentation process gives miso its unique flavor profile. The longer it ferments, the more complex the flavor will be.

It is rich in vitamins, minerals, and antioxidants. It is also a good source of protein and fiber. 

Fermented foods like this are also high in probiotics which are beneficial for gut health. They can help improve digestion and nutrient absorption and promote the growth of healthy gut bacteria.

You can use it in different dishes, such as soups, stews, and marinades. 

There are many different types, which vary in taste and texture. The most common types are white, red, and miso. 

The white is the mildest and sweetest type, while red is the strongest and saltiest. The yellow falls somewhere in between the two in terms of flavor.

It can be found in most Asian markets or online. When shopping for miso, it is important to look for a brand that uses traditional fermentation methods. This will ensure that the flavor and quality is up to par.

Adding this to your diet is an easy way to enjoy its many health benefits. If you’re new to this dish, start with a milder variety and add more as you get used.

White:

White is made from a mix of soybeans and white rice. The proportion of each ingredient varies, but typically, white is made with less soybeans and more white rice than other types.

This gives it a sweeter flavor and a lighter color. In fact, it’s the lightest colored and mildest flavored of the three types of this dish. It’s also made with a shorter fermentation time (usually two weeks to six months) and less salt, thus the sweeter taste. White miso is perfect for soup, salad dressing, and marinades.

Red:

Red miso is darker in color and has a more intense flavor than white miso. It is made with more soybeans and takes longer fermentation times(usually one to five years), and it’s saltier. This gives it a more pungent flavor making it perfect for hearty meals like rich soups, marinades, glazes, and braises.

Yellow:

Yellow is somewhere in between white and red miso in terms of color and flavor. The color ranges from yellow to light brown.

The key ingredient in yellow is soybeans, which are often mixed with barley and sometimes a small amount of rice. 

Unlike other types, yellow is slightly strong in flavor than the white but not as strong as red. 

Yellow has a mild earthy flavor making it suitable for general use, including as a condiment, in soups, marinades, salad dressing, etc.

Health Benefits

1. Aiding in digestion

Miso is a fermented food rich in probiotics, the “good” bacteria that live in your gut and aid digestion. 

Probiotics help break down food, extract nutrients, and prevent the growth of harmful bacteria. Miso also contains enzymes that can help to break down tough-to-digest foods like beans and cruciferous vegetables.

Additionally, miso is a good fiber source, which helps keep things moving through your digestive system. If you are struggling with constipation or other digestive issues, adding miso to your diet may help to alleviate some of your symptoms.

2. Lowers the risk of cancer

Miso contains high levels of phenolic acids and flavonoids, which are antioxidants that can scavenge harmful free radicals and reduce inflammation. 

These properties may help protect cells from damage and lower the risk of cancer.

A study by researchers at the University of Tokyo, looked at the dietary habits of over 6,000 Japanese adults. The participants were divided into three groups based on their miso consumption: those who ate none, those who ate one to two servings per week, and those who ate three or more servings per week.

After following the participants for an average of 12 years, the researchers found that those in the highest miso intake group had a significantly lower risk of developing colorectal cancer than those in the other two groups. 

They also found that miso intake was linked with a lower risk of esophageal cancer.

While the findings are preliminary and more research is needed, they suggest that regularly consuming miso may help to protect against some types of cancer. 

3. Lowering cholesterol levels

Miso contains various compounds shown to have cholesterol-lowering effects in animal studies. For example, one study found that rats fed a diet containing miso had lower levels of LDL (“bad”) cholesterol and higher levels of HDL (“good”) cholesterol than those not fed miso.

Low cholesterol also means less plaque formation, which can reduce blood pressure, lower incidences of atherosclerosis, and promote cardiovascular health.

Although more human research is needed, this shows that miso can play an important role in lowering cholesterol levels.

4. Boosting the immune system

The gut is home to trillions of microbes, including many beneficial bacteria that support a healthy immune system. These good bacteria help keep the bad bacteria in check, and they also produce short-chain fatty acids that have anti-inflammatory effects. A healthy digestive system is, therefore crucial for maintaining a strong immunity. And since miso promotes digestive health, it can thus boost your immune system.

Miso is also a good source of copper and zinc, both of which can help boost immunity by stimulating the production of white blood cells and increasing the activity of natural killer cells. These effects have been observed in both animals and humans.

Regular consumption of miso can help to keep your immune system strong and reduce your risk of getting sick.

5. Preventing osteoporosis

Miso is also a good source of several important nutrients for bone health. These include calcium, phosphorus, magnesium, and copper. Miso also contains phytoestrogens, which are plant compounds that can mimic the effects of estrogen in the body.

Estrogen is important for bone health because it helps to maintain bone density. 

When estrogen levels decline during menopause, women are at increased risk for osteoporosis. Some research suggests that phytoestrogens may help to prevent this condition by preserving bone density.

In one study, postmenopausal women who consumed miso soup daily for 12 weeks had increased levels of markers for bone formation and decreased levels of markers for bone breakdown compared to those who did not consume miso soup. The women who consumed miso soup also had higher levels of circulating estradiol, an active form of estrogen.

These results suggest that consuming miso soup may help to prevent osteoporosis by preserving bone density and preventing bone loss. However, more research is needed to confirm these findings.

6. Promoting heart health

Miso contains compounds that can help protect the heart. These include saponins, phytosterols, and isoflavones. Saponins are known to lower cholesterol and improve circulation. Phytosterols help reduce inflammation. Isoflavones are beneficial for heart health.

Miso has also been shown to reduce the risk of stroke. Studies have found that those who eat miso soup daily have a lower risk of stroke than those who do not consume it regularly. 

This may be due to the fact that miso contains compounds that can help reduce inflammation and blood pressure.

If you are looking for a way to promote heart health, consider adding miso to your diet. It is a delicious way to get some of the nutrients your heart needs to stay healthy and strong!

7. Controlling blood sugar levels

Recent studies have shown that miso may help control blood sugar levels. In one study, rats that were given miso had lower blood sugar levels after eating a high-sugar meal than rats that were not given miso.

The beneficial effect of miso on blood sugar levels is due to the fermentation process, which increases the production of enzymes that help break down carbohydrates. Miso also contains compounds that have been shown to improve insulin sensitivity.

If you are looking for a way to control your blood sugar levels, consider adding miso to your diet.

How to cook with miso?

Miso is a versatile ingredient that can be used in a variety of dishes. Here are some tips on how to cook with miso:

  • Miso can be used as a seasoning for vegetables. Simply add a teaspoon or so of miso to your dish while cooking.
  • You can also use it to make soup. Simply simmer some vegetable broth, and then add miso paste to taste. When adding miso to soup, always add it at the end so that the probiotics are not disrupted.
  • In marinades and sauces. Simply whisk together some miso paste, soy sauce, rice vinegar, and other desired ingredients to create a delicious marinade or sauce
  • Miso can be used as a dressing or dip. Mix miso with some rice vinegar, soy sauce, and sesame oil to make a delicious dressing for salads or vegetable dishes. Or, mix miso with yogurt or sour cream to make a flavorful dip for crackers or vegetables.

Side Effects of Miso

While miso is generally safe to eat, there are some potential side effects to be aware of.

Too much sodium

When it comes to sodium, it is important to know that too much of it can have negative effects on your health. This is especially true if you have high blood pressure or are at risk for heart disease.

Too much sodium can cause your body to retain fluid, which can worsen hypertension (high blood pressure). It can also put a strain on your kidneys and increase your risk for stroke.

Soy allergy

If you have an allergy to soybeans, you should avoid this dish as it will likely trigger an allergic reaction. Symptoms of a soy allergy include hives, wheezing, and difficulty breathing. If you experience any of these symptoms after eating miso, seek medical attention immediately.

Drug interactions

It can also interact with certain medications. Because it contains estrogen-like compounds, it may interfere with hormone therapy or birth control pills. If you take any of these medications, check with your doctor before consuming miso.

GMO

Some people are concerned about it because most of it is made from soybeans, and most soybeans are often genetically modified (GM). If you are concerned about eating GMO foods, you can look for miso products that are made from organic soybeans. You
