Best sugar substitute: our ranking, and the honest downsides

You are standing at the shelf, or a reel has just crowned one sweetener the best sugar substitute in India, and every pack says the same thing: zero this, natural that. The answer is on the ingredient list on the back.

Many people arrive here from a sugar dabba. In our survey of our own buyers, 39% said they had been using regular sugar before, 12% stevia and 9% sugar-free tablets or sachets.

This page ranks the types of sugar substitute on five criteria we state up front, names each one's downside, and says which "best sugar alternative" is still sugar by another name. We make a sweetener from monk fruit, so we publish the criteria and Manvi Agnihotri, our nutrition reviewer, checks the order.

What makes a good sugar substitute (how we ranked)

The best substitute for sugar is the one that does sugar's one job, sweetness, while adding as little of sugar's baggage as possible. A sugar substitute is anything used in place of sugar for sweetness; some add almost no calories, others are sugars under another name.

We scored every type on the same five points:

• Sugar and calories it adds: does a teaspoon's worth of sweetness bring sugar and calories with it, or close to none?
• Taste and aftertaste: does it taste clean in hot chai, or leave something behind?
• What regulators have said: has it been reviewed, and did the reviewers reach a conclusion?
• How your gut takes it at normal amounts: a sweetener you cannot eat a normal portion of is not a daily sweetener.
• How easy it is in an Indian kitchen: chai, coffee, mithai and baking ask different things of it.

Chai and coffee carry the most weight, because that is where the sweetener goes. In our survey of our own buyers, 66% said their sweetener goes into coffee and 64% into chai; 15% bake with it.

Each type gets a score out of 10 from those five points. The weights and the working sit in the "How we compared" box on this page, so you can check the arithmetic and disagree with it.

We rank types, not brands. The same type behaves the same whatever the pack says, so the useful habit is reading the ingredient list to see what a blend is made of. Each ingredient in our sweetener library has its own entry if a name on a label is new to you.

In short: sweetness first, baggage second, and the ingredient list settles the rest.

Tier 1: plant extracts (better sugar substitutes)

Two plant extracts top the list. At the amounts used in a cup they add almost no calories, and they are not sugars [1]. Monk fruit made without sugar alcohols ranks first and stevia second; for the daily cup this tier holds the best sugar substitute, and the best natural sweetener, so taste-test here first.

Monk fruit

Monk fruit (Siraitia grosvenorii, luo han guo) comes from a plant native to southern China [1]. The extract gets its sweetness from compounds called mogrosides, and depending on its mogroside content it is reported to be 100 to 250 times sweeter than sugar, so a cup needs a few drops or a pinch [1].

In the US, purified monk fruit extract and juice concentrate have been through seven safety notices since 2010, and each closed with no questions from the FDA [7]. No acceptable daily intake has been specified for monk fruit; one may not be needed when, among other reasons, an ingredient is shown safe at levels well above the amounts used to sweeten [1].

The full picture is in what regulators say about monk fruit.

The thing to watch is the pack, not the fruit. A pinch of extract cannot fill a spoon, so a monk fruit powder that measures like sugar needs a bulking agent, which may be erythritol (tier 3) or allulose (tier 2).

Of the 44 monk fruit powders we checked on marketplaces and brand websites, 25 contained erythritol, and none stated how much monk fruit was inside [8]. Turn the pack over and read the first ingredient.

At The Sweet Change: our Monk Fruit Sweetener Powder is made with monk fruit, guar fibre and allulose, with no erythritol. Our Monk Fruit Drops have three ingredients: monk fruit extract, water and vitamin C.

Stevia

Stevia sweeteners are steviol glycosides taken from the leaves of Stevia rebaudiana, and they are 200 to 400 times sweeter than sugar [1]. Stevia is the name many shoppers already know; in our survey of our own buyers, 12% said they were using it before they switched.

Its US file is large: the FDA has evaluated many safety notices for high-purity steviol glycosides (95% purity or more) and raised no questions, while whole stevia leaf and crude leaf extracts are not accepted as safe sweeteners there [1]. On a label, "stevia" can mean either, and the purified extract is the one with the record.

The downside is the one everybody mentions: a bitter aftertaste that many people notice in hot chai. A taste study traced that bitterness to two bitter taste receptors on the tongue, TAS2R4 and TAS2R14 [2].

If stevia tastes fine to you, it is a solid daily choice. If it tastes bitter, try a smaller amount or a different form before you give up on it.

Why monk fruit ranks first: taste. In our own two-cup chai test, same milk and same patti, most of the family picked out the stevia cup by the second sip.

That bitter note is why monk fruit made without sugar alcohols is our pick for the daily cup, and why stevia is a sound second if it tastes fine to you.

The two, side by side in the same cup: monk fruit vs stevia.

Tier 2: allulose, a low-calorie sugar

Allulose is the name on this list most readers will not have met. It is a close chemical cousin (an epimer) of fructose, found naturally in small amounts in foods such as wheat, raisins and dried figs [9].

The body uses very little of it. On US nutrition labels it is counted at 0.4 kcal per gram, about a tenth of sugar's 4 kcal, and the US regulator lets makers leave it out of the "Total Sugars" and "Added Sugars" lines [9].

That is a US labelling rule. Do not read it across to an Indian pack.

It has also been through the US safety-notice process without objection [1].

The downsides are practical. Chemically it is a sugar, a monosaccharide, so "not a sugar" is the wrong description even where US labels leave it out of the sugar lines [9].

Read the pack for how much replaces a spoon of sugar.

In short: very few calories on US labels, but chemically still a sugar.

Tier 3: sugar alcohols (erythritol, xylitol and others)

A sugar alcohol (polyol) is a sweetener made from sugars; erythritol, xylitol, sorbitol and maltitol are examples. They run from 25% to 100% as sweet as sugar, carry slightly fewer calories than sugar, and do not promote tooth decay [1].

That bulk is why you find them in sugar-free sweets, biscuits and chewing gum: a sugar alcohol measures like sugar, so the pack feels like sugar [1].

The gut is where the limit shows. Most sugar alcohols are only partly absorbed; the rest draws water into the gut and is fermented in the colon, which is why a large serving can mean wind, bloating or loose motions [3]. Erythritol is the partial exception: about 90% is absorbed and leaves the body unused in urine [3].

How much is too much? In a trial of healthy young adults, 20 g and 35 g of erythritol in one drink were tolerated well, while 50 g brought more reports of nausea and rumbling [4]. In India, a polyol sold as a table-top sweetener carries a note on the pack that it may have a laxative effect [10].

Then there is the heart question. An observational study found higher blood erythritol levels were associated with more heart attacks and strokes in people already under cardiac evaluation [11]. The US FDA reviewed that 2023 paper and determined that the observational studies cited in it did not establish a causal link between consuming erythritol and the observed effects [1].

A small 2024 study (10 volunteers per group) found a 30 g erythritol drink increased platelet reactivity [12]. That is a link, not proof. Still, the 2023 study sent many people back to reading labels, and we see it in our own numbers: in our survey of our own buyers, 49% said they chose us for no erythritol.

In short: useful bulk for cooking, limited by what your gut will take in a day, with an open question on erythritol that the US FDA says it will keep watching [1].

Tier 4: artificial sweeteners (sucralose, aspartame)

These are the tabletop tablets and diet-drink sweeteners. Sucralose is about 600 times sweeter than sugar, aspartame and acesulfame potassium (acesulfame K) about 200 times, and saccharin 200 to 700 times [1]. Their strength is plain: one tablet sweetens a cup.

Two things pull them down our list, and the first is aspartame. In 2023 the WHO's cancer agency, IARC, classed aspartame as "possibly carcinogenic to humans" (Group 2B) on limited evidence, while JECFA, the WHO and FAO expert committee on additives, kept its acceptable daily intake at 40 mg per kg of body weight [13].

IARC flagged a hazard; JECFA left the safe-intake number alone.

The second is bigger, and it reaches back into tier 1. In 2023 the WHO issued a guideline recommending against non-sugar sweeteners as a way to control body weight or cut the risk of long-term disease, and its list of those sweeteners runs from acesulfame K, aspartame, saccharin and sucralose to stevia [14].

The same guideline leaves out sugar alcohols and low-calorie sugars, which it treats as sugars with calories [14].

No sweetener on this page, stevia included, is a weight-loss tool. What it can do is smaller and still worth having: keep your chai sweet while the sugar spoon stays in the dabba.

Bad sugar substitutes? The swaps that are still sugar

Jaggery (gur), honey (shahad), coconut sugar, dates, mishri and khand. They taste wonderful, and the reels call them natural sweeteners and the healthy swap. The honest point is that they are sugar.

Free sugars, in the WHO's definition, include any sugar added by the manufacturer, the cook or you, plus the sugars naturally present in honey and syrups [5]. The advice is to keep them under 10% of daily energy, about 50 g or 12 level teaspoons on a 2,000-calorie day [5]. Gur in kheer and honey in water both count.

The glycemic index tells the same story. In the 2008 international tables honey scores 61 and table sugar 65, both in the medium band, and neither jaggery nor coconut sugar has an entry in those tables at all [6]. Swapping cheeni for gur changes the flavour and the colour of your halwa, not the fact that it is sugar.

If you love gur in your winter chai, keep it as the treat it is, and count it as sugar. How jaggery compares with sugar has the numbers side by side.

In short: enjoy them as the sugars they are. The swap that cuts sugar is the one that leaves the sugar out.

How to pick: chai, coffee, mithai and baking

Chai ka taste wahi chahiye, sugar nahi. That is the whole brief, and the best sugar substitute depends on the cup.

• Daily chai and coffee: a tier 1 drop or powder, and our pick is monk fruit made without sugar alcohols. Taste-test it in your own cup, with your own milk, before you buy a big pack; the same sweetener can taste different in black coffee and in masala chai.
• Mithai and kheer: you need bulk as well as sweetness, so this is where powders with a bulking agent earn their place. Check what the bulk is, erythritol or allulose; if it is erythritol, count the whole plate, because the gut limits in tier 3 add up across chai, mithai and snacks.
• Baking: sugar does more than sweeten in a cake, so no sweetener is a straight swap in a recipe written for sugar. Start by replacing half.
• Nimbu pani and cold drinks: drops dissolve as soon as they land; a powder may need a stir and a minute.

If you are buying for a parent who takes two spoons in every cup, change the spoon before you change the habit: the same cup, the same time, a different sweetener. For more on that choice, read our guide to sweeteners for diabetes.

Cost per cup: what a sweet chai costs

Pack prices mislead here, because sweeteners are not equally sweet. Our Powder is 4:1, so 1 g sweetens like 4 g of sugar, about a level teaspoon, and we count one serving of our Drops to a cup [15]. Most of the monk fruit blends we priced are 1:1, so the same cup needs 4 g of powder [8].

Price the cup, then. With Buy 2 Get 1, our Drops work out at ₹2.66 a cup in the 300-serving pack and ₹3.31 in the 100-serving pack, and our Powder at ₹3.32 and ₹4.50 [15].

A monk fruit blend built on erythritol came to about ₹3.70 a cup and one built on allulose to about ₹4.93 [8]. The maltitol blend we priced came to about ₹4.50 [16].

So the cheapest cup in that list is also one with no sugar alcohol in it: our Drops in the larger pack.

Compare any two, head to head

A ranking tells you the order. It cannot tell you what happens when the two you are choosing between go into the same cup.

That is what our head-to-head pages do: each takes two sweeteners or sugars, or a sweetener against the blends on the market, and compares them on sugar, calories, taste and use, ending with a simplified table you can read on your phone.

This page is the hub for all of them, so every comparison we publish is listed here.

• Monk fruit and jaggery compared: a plant extract against the winter-chai favourite, with the sugar and GI numbers side by side.
• Monk fruit and stevia compared: our two tier 1 picks in the same cup of chai, on taste, the label and cost per cup.
• Monk fruit alternatives compared: erythritol, maltitol and allulose blends against monk fruit made without sugar alcohols, on the label and cost per cup.
• How jaggery really compares with sugar: gur and cheeni on sugar, calories and the GI tables.

Cheat sheet: the best sugar substitute in five lines

• For daily chai and coffee: our pick is monk fruit made without sugar alcohols; stevia is a sound second if its taste suits you.
• Stevia's catch: a bitter aftertaste that many people notice in hot chai.
• Sugar alcohols' catch: your gut sets the daily limit, and erythritol has an open question the US FDA says it is watching.
• Honey, gur and coconut sugar: still sugar, counted as free sugars, so enjoy them as sugar.
• Every pack: read the ingredient list; the first name is the one there is most of.

The best sugar substitute for health is the one that helps you use less sugar and that you will still be using a month from now. If you want the long version of every type on this page, our guide to every type of sweetener goes deeper on each.
