Monk Fruit vs Coconut Sugar: The Unrefined Halo
Coconut sugar looks like the honest option. It comes from a tree, it has a low glycemic index on the packet, and it costs four times what cane sugar costs. A teaspoon of it carries the same fifteen calories.
Coconut sugar is the sap of coconut palm flowers, boiled down until it crystallises. Analyses put it between 70 and 90 per cent sucrose, with glucose and fructose filling almost all of the rest, and a teaspoon carries about 15 kilocalories. A teaspoon of white sugar carries the same 15. The glycemic index of 35 on the packet traces to a single Philippine study of ten adults, while the University of Sydney measured 54 against roughly 64 for sucrose. Its potassium is real and small, around 40 milligrams a spoon against the 3,500 an adult needs daily. Monk fruit decoction sweetens the same cup for about 1 kilocalorie with no glycemic index per portion. Buy coconut sugar for caramel flavour, not for health.
Coconut sugar arrived in health food shops with a very good story. It comes from a tree rather than a factory. It keeps its brown colour instead of being bleached white. The packet mentions a low glycemic index and a list of minerals, and the price sits four or five times above the bag of caster sugar two aisles away.
All of that is true except the part shoppers take from it. Coconut sugar is sugar. It behaves like sugar in your body because it mostly is sucrose, and the arithmetic below is not close enough to argue about.
What coconut sugar is and how it is made
A worker climbs the palm, cuts the tip off an unopened flower spike, and hangs a container under the wound. Sap drips for eight to twelve hours, roughly a litre and a half a day from one spike. That sap goes into a wide pan over an open fire, someone stirs it while the water steams off, and it thickens and grains into brown crystals.
Nothing dishonest happens in any of those steps. The brown colour comes from caramelisation over the flame, not from an additive, and the finished granules smell faintly of butterscotch because of it. What comes out of the pan is a sugar with a little of the sap's minerals and acids still in it.
Is coconut sugar less processed than cane sugar?
Yes, and that is the strongest thing anyone can say for it. Cane juice gets clarified, filtered through carbon, crystallised and centrifuged until the result is 99 per cent sucrose with nothing else left. Coconut sap gets boiled. Fewer steps, less refining, more of the original plant left in the pan.
Fewer steps do not change what the molecule does. The sap was already sugar water before anyone lit the fire, and boiling water off concentrates the sugar rather than removing it. Less processing is a real difference. It just is not a nutritional one.
Where monk fruit works differently
Ours is also fruit and water and heat, so the two processes look similar on paper. The difference sits in what the fruit was carrying. Monk fruit's sweetness comes from mogrosides, which your body does not turn into energy, so boiling the fruit down concentrates sweetness without concentrating sugar. Coconut sap has no mogrosides in it. The steps are in how monk fruit decoction is made.
Calories, sweetness and what a spoon costs you
Start with composition. Published analyses of coconut sugar put sucrose somewhere between 70 and 90 per cent depending on the batch, palm and season, with glucose and fructose taking up most of the remainder and a few per cent of water, minerals and acids left over. Brown cane sugar runs at 96 per cent sucrose or higher. The gap is smaller than the price suggests.
Calories follow directly. Coconut sugar lands near 375 kilocalories per 100 grams against sugar's 400, which works out at about 15 kilocalories in a level teaspoon. A teaspoon of white sugar is 15 to 16. Swapping one for the other saves you nothing you could measure on a kitchen scale, let alone notice.
Sweetness sits at or a shade below sugar, which is why bakers often reach for a little extra to get the same result. Adding a little extra means adding a little more sugar, and the small calorie advantage disappears with it.
Six drops of our liquid sweeten a mug for about 1 kilocalorie. That is the whole of our case on this particular row, and it does not depend on anybody's opinion about flavour.
The two side by side.

Read the last three rows before you write coconut sugar off. It loses every nutrition row and wins three that no drop of liquid can touch.
Coconut sugar is sugar with a nicer backstory and one genuinely good flavour.
The glycemic index of 35, and where it came from
Almost every packet of coconut sugar sold in Europe carries the number 35. Sucrose sits around 64, so 35 reads like a serious difference, and it is the single reason many people pay the premium.
Follow the number back and it thins out fast. It comes from work published by the Philippine Coconut Authority, measured in ten apparently healthy adults, in a country with a large and growing coconut sugar export industry. When the Sydney University Glycaemic Index Research Service tested coconut sugar independently, it measured 54. That sits at the top edge of the low band and within touching distance of table sugar.
Neither result is fraud. Glycemic index testing is genuinely noisy. It uses small groups of volunteers, blood glucose responses vary a great deal between people, and the sample itself varies from palm to palm and season to season. That is precisely why one national dataset of ten people is thin ground for a claim printed on every packet worldwide, and why an independent replication that comes out 19 points higher matters more than the marketing.
The practical version for anyone watching their blood sugar: treat coconut sugar as sugar. A teaspoon in your coffee will do close to what a teaspoon of sugar does. Agave syrup gets sold on the same kind of glycemic index argument, and we took that one apart in monk fruit versus agave syrup.
The mineral claim, with the arithmetic done
Coconut sugar really does contain minerals. Laboratory analyses of Philippine samples report roughly 1,000 milligrams of potassium per 100 grams, along with small quantities of iron, zinc and magnesium. Marketing stops there, and stopping there is the trick, because minerals only mean anything once you divide them by the portion you actually eat.
Forty milligrams a spoon
At about 1,000 milligrams per 100 grams, a four gram teaspoon delivers roughly 40 milligrams. EFSA sets adult potassium intake at 3,500 milligrams a day, so one spoon covers about one per cent of it and brings 15 kilocalories of sugar along for the ride.
Kilograms, not spoons
Published figures sit near 0.5 milligrams of iron and 0.1 milligrams of zinc per 100 grams. A teaspoon holds two hundredths of a milligram of iron. Reaching a woman's daily 16 milligrams from coconut sugar would take about three kilograms of it.
Ten spoons to one banana
A medium banana carries around 420 milligrams of potassium for about 100 kilocalories. Matching that from coconut sugar takes roughly ten teaspoons, which is 40 grams of sugar and 150 kilocalories. The banana wins on every axis, including price.
We bring no minerals either
Six drops of our liquid contain nothing nutritionally useful, and we are not going to pretend otherwise. What they also contain is no sugar, about 1 kilocalorie, and no glycemic index per portion. Get your minerals from dinner.
Sweeteners are a poor delivery route for anything, because you eat them in spoons rather than in portions. Any mineral claim on a sugar has to survive that division, and none of them do.
What coconut sugar does better than we do
Now the part where we lose, because there are things coconut sugar does that no high intensity sweetener will ever do.
It tastes wonderful. There is a caramel and butterscotch note in it that plain sugar lacks entirely, and in gingerbread, flapjacks, banana bread or a dark barbecue sauce that note is the point of the recipe. You cannot get there with drops. Sweetness and flavour are separate jobs, and we only do one of them.
It also works as a bulk sugar. It caramelises, it browns crusts, it holds moisture, it creams into butter and it gives biscuits their spread and their chew. Take the sugar out of a shortbread and you have a different food. Our powder covers some baking, and we set out how far it goes in the monk fruit baking conversion guide, but it will not brown and it will not build structure.
The inulin in coconut sap counts in its favour too. It is a small amount of prebiotic fibre, which is more than white sugar offers, and it is the same reason coconut sugar climbs the FODMAP lists. Dietitian guidance based on Monash testing puts one teaspoon in the low FODMAP range and three teaspoons in the high range for fructans. Anyone managing irritable bowel symptoms should read that as a portion limit.
Sustainability is genuinely mixed rather than clearly better. Tapping a flower spike for sap means that spike will never set the twenty or so nuts it could have carried, so a sugar-tapped palm produces fewer coconuts by design, and growers who tap all twelve spikes produce none. Researchers argue that a tapped palm yields several times more carbohydrate per year than a fruiting one, which is why the comparison with cane is still an open question rather than the settled win the packets imply.
One caveat belongs on our side of the page as well. Ours carries a rare allergy risk for anyone sensitive to the gourd family, which includes melon and cucumber.

How to use both, and when
Five notes, including the recipes where coconut sugar is the right tool.
-
Keep coconut sugar for the caramel jobs
Gingerbread, flapjacks, banana bread, sticky glazes and barbecue sauce all lean on that butterscotch note and on browning. Use coconut sugar there and enjoy it. Buying it for tea is where the money goes to waste.
-
Halve it and finish with drops
Most bakes hold together on half the sugar. Cut the coconut sugar to half, add six drops per teaspoon you removed, and you keep the colour and the caramel while the sugar total drops by half.
-
Sweeten drinks with drops only
Coffee, tea, milk, yogurt, porridge and shakes need sweetness and nothing else. There is no flavour argument for coconut sugar in a mug, and 15 kilocalories a spoon adds up over four cups a day.
-
Log it as sugar, because it is
If you count free sugars, a teaspoon of coconut sugar counts as a teaspoon of sugar. Diabetes organisations treat it the same way. The low glycemic index on the packet is not a reason to relax the count.
-
Hold it to one teaspoon on a low FODMAP plan
One teaspoon tests low for fructans and three tests high, so a generous pour into a smoothie can matter. Drops contain no fermentable fibre at all if you would rather sidestep the question.
One honest tip: if you bought coconut sugar for the minerals, spend the same money on a bag of spinach, a bunch of bananas or a sack of potatoes. Each delivers more potassium in one serving than a whole jar of coconut sugar, and none of them arrives wrapped in 400 grams of sucrose.
Frequently asked questions
Is coconut sugar healthier than white sugar?
Barely, and not in a way that changes anything. It carries about 15 kilocalories a teaspoon against sugar's 15 to 16, it is 70 to 90 per cent sucrose, and its minerals arrive in quantities under one per cent of a daily intake. Treat it as a nicer tasting sugar rather than a health food.
What is coconut sugar made from?
The sap of the coconut palm's flower spike. Workers cut the unopened spike, collect the sap that drips out over eight to twelve hours, then boil it in open pans until it thickens and crystallises. No coconut flesh or coconut water is involved.
Does coconut sugar taste like coconut?
No. It tastes of caramel and butterscotch, close to a light brown sugar, because the sap caramelises over the flame while the water boils off. That flavour is the best reason to buy it.
How many calories are in coconut sugar?
Around 375 kilocalories per 100 grams, against 400 for white sugar. In a level teaspoon that is about 15 kilocalories, which is what a teaspoon of white sugar gives you. The difference is too small to matter in any real diet.
What is the glycemic index of coconut sugar?
The figure of 35 on most packets comes from one Philippine study of ten adults. The Sydney University Glycaemic Index Research Service measured 54 independently, against roughly 64 for sucrose. Given how much glycemic index testing varies, the safe assumption is that it behaves close to sugar.
Can diabetics use coconut sugar?
Only counted as sugar. It supplies about 4 grams of carbohydrate per teaspoon and raises blood glucose, with independent testing putting it at 54 on the glycemic index. Anyone managing diabetes should treat it exactly as they treat table sugar and speak to their own clinician.
Does coconut sugar really contain minerals?
Yes, in amounts that do not help. Analyses report about 1,000 milligrams of potassium per 100 grams, so a teaspoon carries roughly 40 milligrams against a daily adult intake of 3,500. Iron and zinc are lower still, at around 0.5 and 0.1 milligrams per 100 grams.
Is coconut sugar less processed than cane sugar?
Yes, and it deserves the credit. Cane goes through clarification, carbon filtration, crystallisation and centrifuging to reach 99 per cent sucrose, while coconut sap is simply boiled down. Fewer steps leave more of the plant in the pan, though the sugar itself is unchanged.
Can I swap coconut sugar for white sugar one for one?
Yes, by weight, in almost every recipe. It is slightly less sweet, so some bakers add up to a tenth more, and it darkens the finished bake. Expect a caramel note and a browner crumb.
Can coconut sugar cause bloating?
It can in larger amounts, because the sap carries inulin, a fermentable fructan. Dietitian guidance based on Monash testing rates one teaspoon low FODMAP and three teaspoons high for fructans. Most people notice nothing at normal doses.
Is coconut sugar more sustainable than cane sugar?
The honest answer is that it is contested. A tapped flower spike cannot set its twenty or so nuts, so sugar production comes at the cost of coconut production, while researchers point out that a tapped palm yields more total carbohydrate per year. The comparison with cane depends on assumptions nobody has settled.
Can I use monk fruit instead of coconut sugar in baking?
Partly. Drops replace the sweetness at about six drops per teaspoon and roughly 1 kilocalorie, but they will not brown, bulk or caramelise. For gingerbread or flapjacks, halve the coconut sugar and top the sweetness up with drops rather than removing it entirely.
Final thoughts
Coconut sugar is a well made sugar with a good flavour and a story that has run far ahead of the evidence. The low glycemic index rests on ten volunteers and did not replicate. The minerals evaporate the moment you divide them by a teaspoon. The lighter processing is real and changes nothing about what the sugar does once you swallow it.
So keep it, and keep it for the right reason. A tin of coconut sugar in the baking cupboard earns its place in gingerbread and glazes, where the caramel flavour does work nothing else can do. The mug of tea, the bowl of yogurt and the daily coffee are jobs that never needed sugar in the first place, and six drops handle those for about a kilocalorie.
