Komatsuna vs. Spinach: Which Japanese Leaf Packs More Fiber and offers better health benefits for busy Singaporeans?

Jan 29, 2026Otto Park ilwoo

Walk into any FairPrice or Cold Storage in Singapore, and you’ll spot bunches of fresh spinach everywhere. But have you ever tried finding komatsuna? This Japanese green, which locals in Tokyo swear by for strong bones and good digestion, is practically invisible on our shelves—and that’s a shame, because it beats spinach hands down for fiber and nutrition.

Let me tell you why Singaporeans should care about this humble Japanese vegetable, and more importantly, how VegePresso offers a simple way to enjoy its benefits without the hassle of hunting for it at specialty shops, giving you peace of mind.


What’s Komatsuna Anyway?

If you’ve been to a Japanese restaurant in Singapore, you might have seen komatsuna in your miso soup or as a side dish, though most of us wouldn’t know it by name. The Japanese call it “komatsuna” (小松菜), but it’s also known as Japanese mustard spinach or Japanese spinach.

Here’s the thing—despite the name, it’s not actually related to spinach at all. Komatsuna comes from the turnip family, which explains why it’s sturdier and holds up better in cooking than regular spinach that turns to mush in seconds.

The taste? Much milder and sweeter than you’d expect. Unlike regular mustard greens that can be pretty pungent (you know the type—makes your nose tingle), komatsuna is gentle. Even kids who claim to hate vegetables might actually eat this one.

In Japan, this vegetable is so common that it’s like our kailan or chye sim. Japanese families eat it almost daily, and nutritionists there credit it as one reason for their impressive health and longevity. Regularly including it in your diet can help you feel more energized and healthier over time.


Good Old Spinach

Now, spinach needs no introduction, lah. We’ve all bought it at least once, usually with good intentions to “eat healthier” this week. It’s the green vegetable everyone knows—the one Popeye made famous, and the one sitting in your fridge right now, probably starting to wilt.

Spinach is convenient, cheap, and available everywhere in Singapore. NTUC has it; your neighborhood minimart has it; even the 24-hour convenience store probably has it, frozen. It’s been our go-to leafy green for ages.

But is convenience always better? Let’s find out.


The Fiber Face-Off

Okay, straight to the point. If we’re talking about fiber content, komatsuna wins. It packs about 2.8 grams of fiber per 100 grams, while spinach comes in at 2.4 grams for the same amount. That’s roughly 17% more fiber—not bad at all.

Now, why should busy Singaporeans care about fiber? Well, think about our diet here. Chicken rice, char kway teow, nasi lemak, laksa—absolutely shiok, but not exactly fiber-rich, right? Most of us aren’t getting enough fiber, and that shows up as constipation, high cholesterol, and that afternoon food coma after lunch.

Fiber helps keep your digestion regular (important when you’re stuck in the office all day), controls your cholesterol (crucial with our love for santan and carbs), and prevents those blood sugar crashes that make you raid the snack drawer at 3 PM.


Calcium You Can Actually Absorb

Here’s where komatsuna really shows spinach who’s boss. Komatsuna has about 3 times as much calcium as spinach. We’re talking serious numbers here—good for your bones, teeth, and overall health.

But here’s the catch that nobody tells you about spinach: it’s high in something called oxalic acid. Without getting too scientific, oxalic acid basically “locks up” the calcium in spinach so your body can’t absorb it properly. It’s like having money in a bank account you can’t access—technically there, but useless.

Komatsuna has much lower levels of this oxalic acid, which means when you eat it, your body can actually use all that calcium. This is huge for Singaporeans, especially women over 40 who need to worry about bone health.

Plus, if you’ve heard about kidney stones (painful stones), high-oxalate foods like spinach can increase that risk. Komatsuna is much safer in this department.


Why Komatsuna is Actually Better for Singapore Life

Think about our lifestyle here in Singapore. We’re always rushing, always busy, always looking for shortcuts that don’t compromise on health. Komatsuna fits perfectly into this mindset, and here’s why:

Easier on Your Stomach: That lower oxalate content means komatsuna is gentler on your digestive system. If you’ve ever felt bloated or uncomfortable after eating a lot of spinach, you’ll appreciate this difference. Singapore’s hot weather already makes us feel uneasy—we don’t need our food to make it worse.

Better for Your Bones: With our aging population and so many desk jobs leading to poor posture, bone health is crucial. Komatsuna’s high, absorbable calcium is precisely what we need, especially for aunties and uncles worried about osteoporosis.

Steady Energy Throughout the Day: The fiber in komatsuna helps prevent those energy crashes. You know that 3 PM slump where you feel like you need another kopi? Proper fiber intake helps minimize that, keeping you productive throughout your workday.

Weight Management: At only 23 calories per 100 grams but full of fiber, komatsuna fills you up without expanding your waistline. Perfect for Singaporeans trying to maintain a healthy weight despite all the tempting hawker food around us.

Heart Health: With heart disease a primary concern in Singapore, komatsuna’s potassium and fiber help manage blood pressure and cholesterol naturally—no need to rely solely on medication.


The Smart Singaporean Solution

What if you could get all the benefits of komatsuna without the hassle? No hunting at specialty stores, no worrying about vegetables going bad, no extra cooking time.

The VegePresso Japanese 40 Billion Probiotic Green Juice is basically the solution we have been waiting for. Each small packet contains komatsuna along with other Japanese supergreens like barley leaves, broccoli, and yes, even spinach—giving you the best of everything.

Think about this: one packet equals all those vegetables, but without the shopping, washing, chopping, cooking, or waste. Just tear open, mix with water, and drink. Done. That’s the kind of efficiency we Singaporeans appreciate, right?

And here’s the bonus—each packet has 40 billion probiotics. If you’ve been following health trends, you know probiotics are essential for gut health and digestion. With all the oily hawker food and air-conditioned offices wreaking havoc on our digestion, these probiotics are like insurance for your stomach.

The whole formula is made in Japan, so you’re getting authentic Japanese quality—the same stuff that keeps Japanese people healthy and living long lives.


How to Fit VegePresso Into Your Singapore Lifestyle

The beauty of VegePresso is how it slots perfectly into our busy Singapore routines:

Morning Before Work: Mix one packet with water while your coffee brews. Drink it on your way to the MRT or while sitting in traffic. Your daily greens are done before you even reach the office.

Lunchtime at the Office: Had chicken rice again? Balance it out with a packet of VegePresso. Keeps you full longer and prevents that post-lunch food coma that makes afternoon meetings torture.

Pre-Workout: Heading to the gym after work? Mix VegePresso with water for clean, natural energy without the jitters from pre-workout supplements.

Weekend Recovery: After a late Saturday night out at Clarke Quay, VegePresso helps your body recover with proper nutrition. Better than reaching for another kopi.

Traveling for Work: Those small packets fit easily in your laptop bag. Whether you’re flying to Jakarta for meetings or stuck in Johor Bahru for business, you can maintain your healthy habits.


Why VegePresso Makes More Sense Than Fresh Komatsuna


Let’s break down why VegePresso is the more intelligent choice for Singaporeans:

Consistent Quality: Every packet has duplicate nutritional content. Fresh vegetables? Who knows how long they’ve been sitting in the cold room, or how much nutrition they’ve lost.

Cost-Effective: When you calculate the cab fare to specialty stores, the higher price of komatsuna, and the waste from vegetables going bad, VegePresso is cheaper in the long run.

No Maid or Cooking Skills Needed: Whether you live alone, with family, or have a helper, anyone can mix VegePresso—no cooking experience required—unlike fresh komatsuna, which requires proper preparation.

Fits Small HDB Kitchens: Not everyone has huge fridges or lots of storage space. VegePresso packets take up minimal space and don’t require refrigeration.

No Food Waste: In Singapore, where we’re trying to be more environmentally conscious, VegePresso means no throwing away wilted vegetables. Every packet gets used.

Year-Round Availability: Komatsuna is seasonal in Japan. VegePresso gives you the same benefits every day of the year, whether it’s monsoon season or Chinese New Year.


Real Benefits for Singaporeans

When you make VegePresso part of your daily routine, you notice the changes. Better toilet habits within the first week—that’s the fiber and probiotics working together. Very important when you’re eating all that hawker food!

Your energy levels become more stable. No more feeling like you need to nap under your desk after lunch. Your body is getting consistent nutrition instead of surviving on kopi and prata.

For those worried about aging gracefully, the calcium benefits add up over time. Stronger bones mean less worry about falls and fractures as you get older.

The probiotics help with digestion, which is crucial when we’re eating everything from roti prata to bak kut teh to laksa—sometimes all in one day. Your stomach needs all the help it can get.


Make the Switch That Makes Sense

So yes, komatsuna beats spinach in fiber content, calcium absorption, and overall nutrition. But more importantly, you don’t need to stress about finding it fresh or learning how to cook it.

The VegePresso Japanese 40 Billion Probiotic Green Juice gives you all the komatsuna benefits plus extra supergreens and probiotics, in a format that actually fits Singapore life.

With 30 packets per box, that’s a month of daily nutrition sorted. No more vegetables going bad in your fridge. No more feeling guilty about not eating healthy. No more excuses about being too busy.

One packet a day. That’s all it takes. Mix it in the morning before work, or keep a few packets in your office drawer for those days when you know you’re not eating well.

Your body deserves this, especially with how hard we work and how much we compromise on health for the sake of convenience. VegePresso is the rare solution that gives you both the health benefits of Japanese superfoods and the convenience Singaporeans demand.

Ready to join the thousands of Singaporeans who have already made this smart switch? Your daily green boost is just one packet away. And trust me, your future self will thank you for starting today.
