For those concerned about blood sugar levels | The top 5 "blood sugar-friendly foods" to add to your dining table
"What should I actually eat to lower my blood sugar?"
Have you ever thought that?
If you look online, there is an overflow of information saying "this is good" or "that is bad," but actually incorporating it into your daily meals is surprisingly difficult.
So, this time, I will pick out and introduce 5 "blood sugar-friendly foods" that I have actually incorporated into my home and felt the effects of.
🥇 Ranking by "strongest perceived effect" on blood sugar levels
In truth, even after finding out I had diabetes, I didn't pay much attention to specific foods.
That is because I followed the rule of 3 units of staple food, 2 units of protein, and as many vegetables as I liked.
I thought that as long as I kept to this, it would be fine, so I took it lightly.
Beyond that, I just considered the color and made sure the meals were satisfying.
That is the kind of meal I have been preparing, thinking it was enough.
However, after continuing to make diabetic meals for a month,
"Which of these lowers blood sugar?
They say low-GI foods are good, but which ones are those?"
I started thinking about various things.
Because of that, my blood sugar levels have dropped and stabilized.
So, I would like to introduce the foods that I actually tried and found to be good.
1st Place 🥒 The "shield that protects blood sugar" eaten first: "Mozuku Cucumber"
✅ How we serve it at home
Mix thinly sliced cucumber into mozuku seaweed with vinegar and serve in a small bowl.
It's done just by taking it out of the fridge! It looks like a shortcut, but it's actually the ultimate combo.
✅ Why is it effective for blood sugar?
🔸 Fucoidan (the slimy component of mozuku): Creates a barrier on the wall of the small intestine to block sugar absorption!
🔸 Acidity of vinegar: Calms the movement of the stomach tomoderate post-meal blood sugar levels!
🔸 Cellulose in cucumber (insoluble dietary fiber): Activates intestinal movement & increases satiety by chewing thoroughly!
✅ Is there a specific order to eat them in?
① Mozuku seaweed and cucumber (the sliminess coats the intestines)
↓
② Daikon radish salad (enzymes and chewing slow down absorption)
↓
③ Carbohydrates like rice or bread (slow absorption = blood sugar levels are less likely to spike!)
🛡️ By eating it first, it acts as a lid on the "absorption path"!
🕒 What is the best timing? [Recommended for breakfast, lunch, and dinner]
🌅 Breakfast △ Don't force it if the vinegar feels too strong (but it goes well with chilled tofu)
🌞 Lunch ◎ Recommended: Eating it before rice or noodles helps prevent blood sugar spikes!
🌙 Dinner ◎ Recommended: Eating it "smoothly" before a meal also settles your appetite = prevents overeating at night!
✅ Summary (Asked an AI Q&A)
Mom: "How does it affect blood sugar?"
AI: "Fucoidan creates a barrier on the intestinal walls. That's why it slows down sugar absorption! It's a real hard worker."
Mom: "Is there a specific time to eat it during a meal?"
AI: "Above all, the first bite! Eating it first is crucial! Even if you think it's impossible, just one bite is fine."
Mom: "Why add cucumber? Isn't just mozuku enough?"
AI: "That's fine too, of course! But chewing increases satiety and activates intestinal movement. By combining mozuku and cucumber, they become the ultimate duo."
That was the gist of it.It may look plain, but "mozuku and cucumber" is actually the best.
If someone says, "This is lazy cooking, right?", just reply, "Don't underestimate the ultimate duo!" (laughs)
2nd Place 🥗 The more you chew, the more effective it is: "Daikon Radish Salad"!
✅ How I serve it at home
Just thinly slice raw daikon radish!
At home, I serve it with "tuna + non-oil dressing".
Not having to use the stove is a housewife's best friend. Yet, it's an excellent diabetic-friendly dish!
✅ Why is it effective for blood sugar?
🔸 Thanks to amylase (an enzyme).
➡ It slowly breaks down the "carbohydrates" in rice.
🔸 Chewing texture (crunchy)
➡ Increased chewing frequency → Stomach movement settles down, and absorption slows down.
🔸 High water content makes it easy to feel full, andprevents eating too fast or overeating!
✅ Is there a specific order to eat them in?
1. Mozuku seaweed and cucumber (coats the intestines)
↓
2. Daikon radish salad (enzymes and crunchiness further slow down sugar absorption) ↓
3. Rice and main dishes (even when they enter, they are absorbed slowly = blood sugar spikes are less likely to occur!)
In short...
🛡️ It's like "placing a shield of enzymes and chewiness in the path where sugar enters."
🕒 What is the best timing? [Recommended for morning, noon, and night]
🌅 Breakfast: △ Somewhat unsuitable. In the morning, the enzymes in daikon radish can feel cold and may not be gentle on the stomach.
🌞 Lunch: ◎ Recommended. Perfect for lunch, when meals like rice balls or bread tend to be high in carbohydrates!
🌙 Dinner: ◎ Recommended. Since you want to chew and settle down at night, the crunchiness of daikon radish is effective!
✅ Summary (Asked an AI Q&A)
Mom: "How does it affect blood sugar levels?"
AI: "Raw daikon radish contains a digestive enzyme called amylase.
This is an enzyme that breaks down starch (carbohydrates).
Because it slowly breaks down the carbohydrates contained in rice and bread, it
moderates the rise in blood sugar levels!
However, amylase dies when heated💦
That's why daikon radish salad eaten raw is the best!
It slows down the breakdown of carbohydrates and prevents sudden spikes in blood sugar levels."
Mom: "When is the best time to eat it?"
AI: "Lunch or dinner is best! Avoid it in the morning if you are concerned about coldness, or serve it shredded at room temperature."
Mom: "How should I eat it?"
AI: "Tuna + non-oil dressing is great!
If possible, serve it second in the meal (after the mozuku seaweed)."
That was the gist of it.
Carbohydrate breakdown with daikon radish salad.
Furthermore, it is a salad that acts like a helper for diabetes, lowering blood sugar levels and providing a sense of satisfaction.
3rd Place 🍚 Is it counterproductive if you get the order wrong!? The pitfalls of "natto" and how to eat it correctly
✅ How we serve it at home
Simply open the pack, mix well, and eat as is.
Even on days when you have an appetite, starting with "natto first" provides a sense of security.
✅ Why is it effective for blood sugar levels?
🔸 Protein: Slows down the absorption of carbohydrates and helps suppress sudden spikes in blood sugar levels.
🔸 Dietary fiber (mainly insoluble): Helps intestinal movement and is useful for the excretion and control of sugar.
🔸 Vitamin B complex & Nattokinase: Also great for improving blood flow and boosting metabolism.
(*Not direct, but an added bonus factor)
✅ However... be careful with "Natto Rice"!
A common pattern👇
"I'm hungry! → Wolf down some natto rice! → It's delicious, but... my blood sugar spikes!"
With this way of eating, the carbohydrates in the rice are absorbed first, and the benefits of the natto can't keep up💦
✅ Is there a specific order to eat in?
① Mozuku seaweed and cucumber (blocks absorption)
↓
② Daikon radish salad (slows down the decomposition speed)
↓
③ Natto (further controls absorption with protein)
↓
④ Rice (by this time, the blood sugar spike is suppressed!)
🛡️ Protein isn't a "shield," but a "speed control device"
→ It acts as something that says "Wait a minute!" to slow down the pace of carbohydrate absorption!
🕒 What is the best timing? [Recommendations for breakfast, lunch, and dinner]
🌅 Breakfast: ◎ Since it tends to be a set with rice, eating just the natto first is effective
🌞 Lunch: ○ If you have a bento or a natto roll, the eating order might be a bit difficult
🌙 Dinner: ◎ Since you want to focus on protein at night, starting with natto is a good idea!
✅ Summary (Asked an AI Q&A)
Mom: "How does it affect blood sugar levels?"
AI: "Protein slows down the absorption of sugar. In other words, it prevents sudden spikes."
Mom: "If protein suppresses sugar absorption, wouldn't tofu, eggs, fish, or meat work too?"
AI: "Correct!
Tofu is absolutely fine too.
As long as it's protein, 'whether it's natto, tofu, or eggs,' it has the effect of preventing sudden spikes in blood sugar."
🧠 Why does protein affect blood sugar levels?
When you add protein to your meal👇
It stays in the stomach longer
→ Carbohydrates reach the intestines slowlyInsulin secretion begins earlier
→ This creates a "defensive posture"As a result, blood sugar levels rise gradually
That's what it means."
Mom: "Is it not okay with rice? Natto rice is the best, though."
AI: "It's not forbidden, but the order is important! Eat the natto first, then the rice!"
Mom: "Oh... okay (laughs). Should I eat it every day?"
AI: "If you can eat it, that's fine! But don't force yourself on days when the smell bothers you."
That was the point.
Natto has long been called an excellent food.
Because of that, I thought it was "justice," but if you get the order wrong, it becomes a "traitor" instead.
Moreover, "together with rice is a no-go."
Before mixing it with rice, eat at least one bite of natto. That seems to be the trick to protecting your blood sugar levels.
4th Place 🐟 The "power of blue-backed fish" that regulates you from within
✅ How I serve it at home
A little bit of grated daikon radish on canned mackerel in water.
Or mackerel simmered in miso, with the sweetness adjusted using Pal Sweet.
But the thing that appears on our table most often is grilled fish (laughs).
✅ Why is it effective for blood sugar?
🔸DHA/EPA (Omega-3 fatty acids)Improves insulin sensitivity and makes it easier to lower blood sugar smoothly
🔸Protein/Carbohydrate absorption slows down → Suppresses rapid spikes in blood sugar
🔸Lipids (high quality) increase satiety → Also effective in preventing snacking
✅ Is there a specific order to eat?
Blue-backed fish are not the type that "lowers it instantly with a punch," but rather a "block from within" type that
prepares your body to be more responsive to insulin① Eat the fish first (fullness from protein & fat + slower absorption)
↓
② Then eat the main dish and rice → This makes it harder for blood sugar levels to spike
↓
③ By continuing this, your insulin sensitivity will also improve
🛡️ It protects you with a double effect: "constitution improvement" + "braking by eating order"
🕒 What is the best timing? [Recommended for morning, noon, and night]
🌅 Breakfast △ High difficulty (canned fish is fine, but the smell might be a concern)
🌞 Lunch ○ Somewhat suitable (be careful with salt content if putting it in a bento)
🌙 Dinner ◎ Recommended! Also great for nighttime blood sugar management and fat adjustment!
✅ Summary (Asked an AI Q&A)
Mom: "How does it affect blood sugar?"
AI: "DHA and EPA support insulin effectiveness, and the protein slows down absorption."
Mom: "When should I eat it? What is most effective?"
AI: "Dinner is recommended. Fish keeps you full longer and can also prevent 'nocturnal spikes' in blood sugar."
Mom: "Is it necessary every day?"
AI: "It's easier to see results by continuing it. 2-3 times a week would be good."
That was the gist of it.
In our house, we can't keep a stock of fish.
Of course, it's just a matter of putting it in the fridge, but my daughter returns it if she senses even the slightest fishy smell, so stocking up is a no-go.
In the end, once a week was the limit.
Even so, my blood sugar levels dropped significantly, so consistency must be the key.
5th Place 🍄 Unassuming but reliable, "mushrooms are the unsung heroes of blood sugar"
✅ How we serve it in our house
Unfortunately, we basically don't serve mushrooms in our house because my daughter dislikes them.
Even a trace amount of mushroom scent makes her refuse to touch her chopsticks, but
"Are mushrooms really such pungent ingredients?" *whisper*... (lol)
But for families who can eat them, they are a versatile ingredient that can be enjoyed deliciously by adding a little to miso soup or mixing them into stir-fries.
✅ Why is it effective for blood sugar?
🔸 Insoluble dietary fiber (cellulose) activates bowel movement → Slows down sugar absorption!
🔸 Water content & low calories create a feeling of fullness → Naturally reduces the amount of rice and side dishes!
🔸 GI value is almost zero, has almost no effect on blood sugar → The ultimate substitute ingredient!
**What is the GI value?** It is a guideline for how quickly a food raises blood sugar levels. The higher the GI value, the more blood sugar rises, and the lower it is, the more gradual the rise.
✅ Is there an order to eating?
Before carbohydrates enter, use dietary fiber to regulate bowel movement
Rather than "directly suppressing blood sugar," mushrooms are more of a "ground-leveling role" that
slows down sugar absorption and suppresses the peak.
If you line up everything mentioned so far, the order looks like this.
① Mozuku seaweed and cucumber (coats the intestines & blocks absorption!)
↓
② Daikon radish salad (slows down sugar decomposition)
↓
③ Mushroom dishes (further adjusts absorption speed)
↓
④ Mackerel (controls absorption with protein)
↓
⑤ Natto (further slows down the sugar absorption of rice)
↓
⑥ Rice (finally, the carbohydrates arrive! But absorption is in slow-motion mode!)
↓
⑦ Miso soup (post-meal fullness + saltiness increases flavor satisfaction / great for post-meal calmness)
🛡️ Of course, you don't need to serve everything.
If you served all of this every day, your wallet would cry (lol)
🕒 What is the best timing? [Recommendations for morning, lunch, and dinner]
🌅 Breakfast △ Might be tough for people who dislike mushrooms... (but miso soup is okay)
🌞 Lunch ◎ Recommended! Easy to mix into stir-fries or dressed dishes for bento boxes
🌙 Dinner ◎ Recommended! Can be used to "bulk up" main dishes to create a feeling of fullness!
✅ Summary (Asked an AI Q&A)
Mom: "How does it affect blood sugar?"
AI: "It slows down sugar absorption with dietary fiber and moderates the peak of blood sugar levels."
Mom: "Do I have to eat it?"
AI: "You don't have to force yourself to eat it! But if you can, there's no harm in including it!"
Mom: "Which mushrooms are good?"
AI: "Shimeji, king oyster, maitake, shiitake... all are low-carb.
And, low GI, so they are effective!"
That was the conclusion.
Since my daughter dislikes these ingredients, they are banned in our house, but if you can eat them, they are convenient ingredients that "go with anything."
Moreover, they are the "unsung heroes that are plain but effective" at suppressing sudden spikes in blood sugar.
