7 Hidden Benefits of Fermented Soybeans Doctors Are Talking About for Women Over 40!
But what if I told you there's one traditional fermented food, something our grandmothers have been eating for thousands of years, that could actually help with both bone loss and menopause symptoms at the same time? It sounds unbelievable, right? I thought so too, until I saw the science.
Today, I want to share with you the seven hidden benefits of fermented soybeans, especially Cheonggukjang, that even Western medical experts are now paying close attention to. By the time you finish reading this post, you might start to see your breakfast in a whole new way.
What You'll Learn:
- How fermented soybeans differ from regular soybeans
- Seven science-backed health benefits for women over 40
- Practical ways to incorporate fermented soybeans into your diet
- Important safety considerations
What Are Fermented Soybeans?
First, let's understand what fermented soybeans actually are. It's really not complicated. You simply take cooked soybeans and ferment them with beneficial bacteria. Korean Cheonggukjang and Japanese Natto are the most famous examples. Some people love them, some struggle with that unique smell and sticky texture, but once you know the benefits, your perspective will completely change.
Here's the important thing. Regular soybeans and fermented soybeans are completely different foods. Something almost magical happens during the fermentation process.
First, the proteins break down into amino acids. What does this mean? It means your body can absorb them directly without needing to digest them first. The absorption rate goes up to over 90 percent. Regular soybeans are only about 60 percent absorbable.
Second, vitamin K2 increases dramatically. How much are we talking about? More than 100 times the original amount. This becomes the key to bone health.
Third, the isoflavones become activated. These are crucial for relieving menopause symptoms, and after fermentation, the body's absorption rate increases by three times.
So to summarize, regular soybeans are definitely healthy, but fermented soybeans are on a completely different level. They're a true superfood.
Benefit 1: Increases Bone Density
This is really important because most people think bone loss is just inevitable as we age. But fermented soybeans completely flip this belief upside down.
There was a large-scale study in Japan where they tracked menopausal women for three years. They divided them into two groups, those who ate fermented soybeans daily and those who didn't. The group that ate fermented soybeans saw their bone density increase by an average of 2.3 percent. Meanwhile, the group that didn't eat them actually lost 4.1 percent of their bone density.
Do you realize how significant this difference is? Every 1 percent difference in bone density reduces fracture risk by 12 percent. So a 6 percent difference means reducing fracture risk by over 70 percent.
The secret is in vitamin K2. Vitamin K2 acts like a traffic cop, directing calcium to your bones instead of your blood vessels. When we consume calcium, it needs to go to our bones. But if it builds up in blood vessel walls instead, that causes arterial hardening. Vitamin K2 guides this calcium precisely to the bones and not the arteries. So your bones get stronger and your blood vessels stay clean.
Guess how much vitamin K2 is in 100 grams of Cheonggukjang? A whopping 800 percent of the daily recommended amount. A large study from the Netherlands showed that people with high vitamin K2 intake had 65 percent lower fracture risk.
Benefit 2: Relieves Menopause Symptoms
Why is menopause so difficult? When menopause hits, estrogen levels drop dramatically. Estrogen does so many important things in our body, and when it suddenly disappears, the body goes into confusion mode. That's why you get hot flashes, insomnia, and mood swings like a roller coaster.
But the isoflavones in fermented soybeans solve this problem. Isoflavones are called plant estrogens because their structure is 70 percent similar to actual estrogen. So they gently substitute for the missing hormones.
A Dutch research team studied 247 menopausal women. The results for the group that consumed fermented soy products daily were truly amazing. Hot flashes decreased by 45 percent, almost cut in half. Night sweats that wake you up also reduced significantly. Sleep quality improved by 35 percent, and mood swings decreased by 40 percent.
Here's an important point. Regular soybeans do contain isoflavones. But the isoflavones in fermented soybeans are three times more powerful. During fermentation, the form of isoflavone changes from glycoside to aglycone, and this form is much better absorbed by our body.
Benefit 3: Protects Heart and Blood Vessels
This is really important, especially for menopausal women. During fermentation, a special enzyme called nattokinase is created. This enzyme has the ability to directly break down blood clots. Blood clots are lumps of coagulated blood, and when they block blood vessels, you can get heart attacks or strokes.
The Japanese Heart Association conducted a large study with impressive results. Bad cholesterol, the LDL, decreased by an average of 10 percent. Good cholesterol, HDL, increased by 15 percent. And triglycerides dropped by a whopping 20 percent.
How good are these results? They're similar to taking cholesterol medication. But medication has side effects and you have to take it for life. Fermented soybeans are just food and produce these effects.
There's something even more amazing. Blood vessel elasticity improved. They measured the arterial stiffness of people who ate fermented soybeans for 12 weeks, and it improved by 18 percent. Why are elastic blood vessels important? Blood pressure stabilizes and the burden on your heart reduces.
Here's what menopausal women need to know. Before menopause, estrogen protects your cardiovascular system. But after menopause, without estrogen, cardiovascular disease risk increases by five times. This is exactly when fermented soybeans can really help.
Benefit 4: Naturally Lowers Blood Pressure
A study was done with 200 high blood pressure patients. They had them eat fermented soybeans daily for 8 weeks, and the results were impressive. Systolic blood pressure dropped by an average of 12 points. Diastolic blood pressure went down by 8 points.
How significant is this? It's similar to taking mild hypertension medication. Plus, there are no side effects at all.
The secret is in peptides. During fermentation, proteins break down and special peptides are created. These peptides block the enzyme that raises blood pressure. Our body has an enzyme called ACE that constricts blood vessels and raises blood pressure. The peptides in fermented soybeans block this ACE enzyme. So blood vessels relax and blood pressure naturally goes down.
Benefit 5: Revolutionizes Gut Health
Fermented soybeans have two secret weapons for gut health. First is probiotics. There are one billion live beneficial bacteria per gram. The Bacillus bacteria in fermented soybeans are really strong against stomach acid. 99 percent of them reach the intestines alive.
Second is prebiotics. The dietary fiber in fermented soybeans becomes food for the good bacteria living in your gut. So gut microbiome diversity increases by 50 percent.
Korean researchers conducted a 12 week experiment with amazing results. Symptoms of irritable bowel syndrome improved by 60 percent. Constipation decreased by 70 percent. Gut inflammation markers also dropped by 40 percent.
Why is gut health important? 70 percent of our immune cells are in the gut. When the gut is healthy, immunity improves too.
Benefit 6: Strengthens Immune System
Studies have tracked people who ate fermented soybeans, and they found that the frequency of catching colds decreased by 35 percent. What's even more interesting is that even when they did catch colds, recovery was faster. Normal people take about a week, but people who ate fermented soybeans recovered 40 percent faster.
Why does this happen? Because of NK cells. NK stands for Natural Killer cells. They're like special forces in our body. They find and directly eliminate cancer cells or virus infected cells.
When you eat fermented soybeans, the activity of these NK cells increases by 25 percent. So your body's defense power becomes much stronger.
Benefit 7: Anti-Inflammation and Anti-Aging
Chronic inflammation is the root cause of almost all chronic diseases. During menopause, inflammation explodes as estrogen decreases. That's why various diseases develop after menopause.
The anti-inflammatory effects of fermented soybeans are truly amazing. CRP, an inflammation marker, dropped by 30 percent. The inflammatory substance IL-6 decreased by 25 percent, and TNF-alpha reduced by 20 percent.
The antioxidant capacity is also excellent. The polyphenols in fermented soybeans contain twice as much as regular soybeans.
What's even more interesting is the skin improvement effect. They measured the skin of people who ate fermented soybeans for 8 weeks. Wrinkles reduced by 15 percent. Skin hydration increased by 22 percent, and skin elasticity improved by 18 percent.
How to Consume Fermented Soybeans
For Cheonggukjang, 50 to 100 grams per day is enough. That's about one small package. If you eat Natto, 40 to 50 grams, so one package is fine. If you use Cheonggukjang powder, one to two tablespoons per day is appropriate.
The best times to eat it are on an empty stomach in the morning to maximize probiotic absorption, or at dinner because vitamin K2 promotes bone formation while you sleep at night.
If you want to enhance the effects even more, try these combinations. Eating it with vitamin D doubles calcium absorption. So adding mushrooms or eggs to your Cheonggukjang is perfect. Eating it with seaweed like kelp is also good for thyroid health. Eating it with kimchi creates a synergy effect for gut health.
Important Precautions
First, if you take blood thinning medication like warfarin, you need to be careful. Vitamin K2 can interfere with the medication's effectiveness. Please consult your doctor first.
Second, people with thyroid disorders also need caution. A component called goitrogen in soybeans can affect thyroid function. If you keep it under 100 grams per day, there's no problem.
Third, if you struggle with the smell, choose frozen products and the smell is much less. Or you can mix Cheonggukjang powder into smoothies or add it to cooking.
When choosing products, check for organic soybeans and no synthetic additives. If you're trying it for the first time, start with small amounts to avoid gas. Give your body time to adapt.
Final Thoughts
Today we learned about the wonderful power of fermented soybeans. Isn't it amazing that just one simple food can bring so many benefits? It's something our ancestors have cherished for thousands of years, and it's still here to support our health today.
Remember, staying healthy isn't about doing something big or complicated. It's about the small choices we make every day. Starting today, try adding one package of Cheonggukjang to your breakfast. If that feels like too much, just add a spoonful of Cheonggukjang powder to your smoothie.
Try it for three months and see how your body responds. You might notice your steps feel lighter when you climb stairs, you sleep more deeply at night, and your skin starts to glow when you look in the mirror.
Don't wait until you lose your health to realize its value. Start now, and your future self will thank you for the choice you made today. Healthy bones, peaceful days, and a vibrant life are all within your reach.
