Sweeteners for diabetics: the best choices for blood sugar and type 2 diabetes

People with diabetes can use a range of sweeteners and sugar substitutes, but the different options are not nutritionally identical. Some contain little or no carbohydrate and have minimal direct effect on blood glucose, while others, including honey, maple syrup, agave and other sugars, still provide carbohydrates that can raise blood sugar.

Choosing sweeteners for diabetics therefore involves more than simply looking for a product labelled “sugar-free” or “natural”. It is useful to consider the carbohydrate content, portion size, ingredients, effect on blood sugar and how the sweetener will be used in drinks, cooking or baking.

This guide compares the best sweeteners for diabetics, including natural and artificial sweeteners, sugar alcohols and common sugar alternatives. It also looks at sweeteners for type 2 diabetes, their potential effects on blood sugar and insulin, and how to choose a sugar substitute that fits into an overall diabetes-friendly eating pattern.

A practical guide to choosing sweeteners and sugar substitutes while considering blood sugar, carbohydrates and everyday use.

What are the best sweeteners for diabetics?

The best sweeteners for diabetics are generally those that can provide sweetness with less available carbohydrate than sugar, while also being suitable for the way they will be used. Options such as stevia, monk fruit, erythritol and some artificial sweeteners differ in their calorie content, effect on blood sugar, sweetness and suitability for cooking or baking.

There is no single best sugar substitute for diabetics for every situation. The table below compares some commonly used sweeteners and sugar substitutes to help show the main differences.

Sweetener	Type	Calories and carbs	Blood sugar considerations	Best uses
Stevia	High-intensity sweetener	Very little or none in pure forms	Generally has little direct effect on blood glucose	Drinks, coffee, porridge and cereal
Monk fruit	High-intensity sweetener	Very little or none in pure forms	Generally has little direct effect on blood glucose	Hot and cold drinks and general sweetening
Erythritol	Sugar alcohol (polyol)	Very low in calories	Generally has little effect on blood glucose	Baking, desserts and drinks
Allulose	Rare sugar	Low in calories	Generally has little effect on blood glucose	Baking, desserts and sauces
Xylitol	Sugar alcohol (polyol)	Contains calories and some available carbohydrate	Usually produces a smaller blood glucose response than sugar	General sweetening and some cooking
Sucralose	High-intensity artificial sweetener	Very little or none in pure forms	Pure sucralose has little direct effect, but blended products vary	Drinks and products formulated for cooking or baking
Aspartame	High-intensity artificial sweetener	Used in such small amounts that it contributes very few calories	Generally has little direct effect on blood glucose	Drinks and foods that do not require prolonged high heat
Saccharin	High-intensity artificial sweetener	Very little or none	Generally has little direct effect on blood glucose	Tabletop sweetening and drinks

The most suitable choice therefore depends on more than whether a sweetener is labelled natural, artificial or sugar-free. The ingredients in the finished product, the amount used and whether it is intended for drinks, cooking or baking can all matter.

The individual sweeteners below look at these differences in more detail, including their practical uses and blood sugar considerations.

Stevia

Stevia is a high-intensity sweetener made from compounds called steviol glycosides, which are extracted from the leaves of Stevia rebaudiana. It is much sweeter than sugar, so only a small amount is needed to sweeten foods and drinks.

Pure steviol glycosides contain little or no available carbohydrate and generally have little direct effect on blood glucose when used in typical amounts. This can make stevia a useful alternative to sugar for people with diabetes, particularly in drinks, yoghurt, porridge and other foods where only sweetness needs to be replaced.

However, products sold as stevia are not always pure steviol glycosides. Granulated and tabletop versions may contain other ingredients, such as erythritol, maltodextrin or dextrose, to provide bulk and make them easier to measure. The nutrition information and ingredients list are therefore more useful than the word “stevia” alone when assessing a product.

Stevia can be a practical sugar substitute, but the finished product matters. If you use stevia regularly, check whether it is a pure extract or a blend and consider any additional carbohydrates in the product.

For a closer look at stevia, blood glucose and different stevia products, see does stevia raise blood sugar?

Monk fruit

Monk fruit, also known as luo han guo, is a fruit native to parts of Asia. Monk fruit sweeteners are made using compounds called mogrosides, which provide an intense sweet taste without the amount of sugar found in conventional nutritive sweeteners.

Pure monk fruit extract contains little or no available carbohydrate and generally has little direct effect on blood glucose when used in typical amounts. This can make monk fruit a useful sugar alternative for people with diabetes, particularly for sweetening drinks, yoghurt and other foods.

As with stevia, it is important to distinguish pure monk fruit extract from commercial monk fruit sweeteners. Many products combine monk fruit with erythritol or other ingredients to provide bulk and make the product easier to measure. The carbohydrate content and potential effect on blood sugar therefore depend partly on the complete product rather than monk fruit extract alone.

Monk fruit can be a useful alternative to sugar, but checking the ingredients and nutrition information is important when choosing a blended product.

For more detail on the different forms and their potential effect on blood glucose, see can diabetics eat monk fruit?

Erythritol

Erythritol is a type of sugar alcohol, or polyol, that occurs naturally in small amounts in some foods and can also be produced commercially through fermentation. It provides sweetness with substantially fewer calories than sugar and is commonly used in sugar-free and reduced-sugar foods and sweetener blends.

Most erythritol is absorbed in the small intestine and later excreted largely unchanged in urine. As a result, it generally has little direct effect on blood glucose and provides very little usable energy. This makes erythritol different from some other polyols, which may be partly metabolised and have a greater effect on blood sugar.

Erythritol can still cause digestive symptoms in some people, particularly when larger amounts are consumed. Products containing erythritol may also include other sweeteners or ingredients, so it is worth checking the full ingredients list and nutrition information rather than considering erythritol in isolation.

Erythritol can be a useful alternative to sugar, particularly when a sweetener with some of the bulk of sugar is needed. Portion size and the other ingredients in the finished product should still be considered.

For a closer look at erythritol and its potential effects on blood glucose and insulin, see does erythritol spike insulin?

Allulose

Allulose is a type of sugar known as a rare sugar because it occurs naturally in only small amounts in foods such as figs and raisins. It has a similar chemical composition to fructose but a different structure, which means the body handles it differently from conventional sugars.

Allulose provides around 70% of the sweetness of table sugar but substantially fewer calories. Most of the allulose consumed is absorbed but is not metabolised in the same way as glucose or fructose, so it generally has little direct effect on blood glucose. Its sugar-like bulk and cooking properties can also make it useful in products where high-intensity sweeteners do not provide the same texture or volume as sugar.

Availability is an important consideration. Allulose is permitted for use in foods in some countries, including the United States, but its regulatory status differs internationally. In the UK and European Union, allulose has been subject to the novel food authorisation process, so consumers should check its current approval and availability in their country.

Allulose has properties that can make it an interesting alternative to conventional sugar, particularly where both sweetness and bulk are required. However, its availability and regulatory status vary by country, and the ingredients in commercial products should still be checked.

For a closer look at its blood sugar effects, practical uses and availability, see allulose for diabetics.

Xylitol

Xylitol is a sugar alcohol, or polyol, that occurs naturally in small amounts in some fruits and vegetables and is also produced commercially for use as a sweetener. It has a sweetness similar to table sugar, which can make it easier to use in foods and drinks where a sugar-like level of sweetness is wanted.

Unlike erythritol, xylitol provides some calories and is partly metabolised by the body. It generally produces a smaller rise in blood glucose than table sugar, but it should not be treated as having no effect on blood sugar. The amount used, total carbohydrate intake and the other ingredients in the food or product remain important.

Larger amounts of xylitol can cause digestive symptoms, including bloating, gas or diarrhoea, particularly in people who are not accustomed to sugar alcohols. Xylitol is also highly toxic to dogs, so foods and sweeteners containing it should always be stored safely away from them.

Xylitol can provide sugar-like sweetness with a smaller blood glucose effect than conventional sugar, but it still provides energy and should be considered as part of the overall diet.

For more detail on its carbohydrate content, portion size and effect on glucose, see can a diabetic eat xylitol?

Sucralose

Sucralose is a high-intensity artificial sweetener that is much sweeter than sugar, so only a very small amount is needed to provide sweetness. Pure sucralose contributes little or no available carbohydrate in the amounts normally used and generally has little direct effect on blood glucose.

However, products containing sucralose can vary considerably. Some granulated and powdered versions contain ingredients such as maltodextrin or dextrose to provide bulk and make the sweetener easier to measure. These ingredients can add small amounts of carbohydrate, particularly when larger quantities of the product are used in cooking or baking.

When considering sucralose for type 2 diabetes, it is therefore useful to look at the complete product rather than the sweetener alone. Checking the ingredients list, carbohydrate content and serving size can help distinguish pure or concentrated sucralose products from blends that contain additional carbohydrates.

Sucralose can be a practical alternative to sugar, particularly when reducing added sugar, but different sucralose products are not nutritionally identical.

For a closer look at the evidence, product differences and blood sugar considerations, see is sucralose bad for type 2 diabetes?

Aspartame

Aspartame is a low-calorie, high-intensity artificial sweetener that is around 200 times sweeter than sugar. Because only a very small amount is needed to provide sweetness, the amount of calories and carbohydrate contributed in typical use is very small.

Aspartame generally has little direct effect on blood glucose when consumed in the small amounts used to sweeten foods and drinks. It is commonly found in sugar-free and reduced-sugar soft drinks, tabletop sweeteners and other foods where replacing added sugar can reduce the overall carbohydrate and calorie content.

Aspartame is less suitable for some types of cooking and baking because prolonged exposure to high temperatures can reduce its sweetness. People with phenylketonuria (PKU) must avoid or restrict aspartame because it contains phenylalanine, which is why products containing aspartame carry a warning for people with this condition.

Aspartame can be a practical way to reduce added sugar in suitable foods and drinks, but its heat sensitivity means it is not the best choice for every use.

For more detail on its safety and blood sugar considerations, see aspartame for diabetics.

Saccharin

Saccharin is a high-intensity artificial sweetener that has been used as a sugar substitute for many years. It is much sweeter than sugar and provides little or no energy in the small amounts normally used, making it a common ingredient in tabletop sweeteners and some sugar-free foods and drinks.

Saccharin is not metabolised by the body in the same way as sugar and generally has little direct effect on blood glucose. This can make it useful for people with diabetes who want to reduce added sugar or carbohydrate while retaining sweetness in foods and drinks.

One practical consideration is taste. Saccharin can have a bitter or metallic aftertaste, particularly at higher concentrations, so some products combine it with other sweeteners to produce a more balanced flavour. As with other sweetener blends, checking the ingredients and nutrition information can help identify what the finished product contains.

Saccharin can provide sweetness with little direct effect on blood glucose, although its distinctive taste means personal preference often determines whether it is a suitable choice.

For more information about its use and blood sugar considerations, see saccharin for diabetics.

The best sweeteners for diabetics are not necessarily the same for every person or every use. Stevia and monk fruit provide intense sweetness in small amounts, erythritol and xylitol offer some of the bulk associated with sugar, while artificial sweeteners such as sucralose, aspartame and saccharin provide other options for reducing added sugar.

The type of sweetener is only part of the picture. Its ingredients, carbohydrate content, portion size and the form in which it is sold can all influence how suitable it is for a particular food or eating pattern. The next section looks more closely at how sweeteners affect blood sugar, including why some have much less direct effect on blood glucose than conventional sugar.

How do sweeteners affect blood sugar?

Sweeteners can affect blood sugar differently depending on what they are made from and how the body digests and absorbs them. Conventional sugars such as sucrose, honey and maple syrup provide available carbohydrate, while many high-intensity sweeteners provide little or no carbohydrate in the amounts normally consumed.

Sugar alcohols and other sugar alternatives sit somewhere between these groups and need to be considered individually. Some have very little direct effect on blood glucose, while others can produce a smaller blood glucose response than conventional sugar. Commercial products may also combine several ingredients, so the effect of the finished product can differ from that of the named sweetener alone.

Rather than treating all sweeteners and blood sugar responses as the same, it is more useful to compare their available carbohydrate, portion size and how each sweetener is metabolised.

Sweeteners that don't raise blood sugar

People looking for sweeteners that don’t raise blood sugar will often come across stevia, monk fruit, erythritol and several artificial sweeteners. In their pure forms, many of these provide little or no available carbohydrate in the amounts normally used and therefore generally have little direct effect on blood glucose.

However, “doesn’t raise blood sugar” should not be treated as an absolute description of every product containing these sweeteners. Granulated and tabletop products may contain dextrose, maltodextrin, other polyols or additional ingredients that change the carbohydrate content of the finished product.

There are also important differences between the main groups:

High-intensity sweeteners: Stevia, monk fruit, sucralose, aspartame and saccharin are used in very small quantities and generally contribute little or no available carbohydrate in typical servings.
Sugar alcohols and rare sugars: Erythritol generally has little direct effect on blood glucose, while other polyols such as xylitol can have a greater, although usually smaller, effect than sugar.
Nutritive sweeteners: Honey, maple syrup, agave and conventional sugar contain carbohydrate and can raise blood glucose, even when they are marketed as natural alternatives to refined sugar.

When looking for sugar substitutes that don’t raise blood sugar, options that provide little or no available carbohydrate are generally the most relevant, but the ingredients and serving size of the finished product still matter.

The glycaemic index is another way sweeteners are sometimes compared, although it should be interpreted alongside the amount actually consumed.

Glycaemic index of sweeteners

The glycaemic index, or GI, describes how quickly a carbohydrate-containing food raises blood glucose compared with a reference food. A lower GI generally indicates a slower or smaller blood glucose response, but GI alone does not tell the whole story because the amount of carbohydrate eaten is also important.

The glycaemic index of sweeteners can therefore be useful for broad comparison, but values can vary between sources and products. For sweeteners that contain little or no available carbohydrate, assigning a GI value is also less informative than simply recognising that very little glucose-producing carbohydrate is being consumed.

Sweetener	Typical blood sugar effect	Key consideration
Stevia	Little direct effect in pure forms	Commercial blends may contain other ingredients
Monk fruit	Little direct effect in pure forms	Often blended with erythritol or other ingredients
Erythritol	Generally very little direct effect	Large amounts may cause digestive symptoms
Allulose	Generally little direct effect	Availability and regulatory status vary by country
Sucralose	Little direct effect in pure forms	Granulated products may contain carbohydrate-containing bulking agents
Aspartame	Generally little direct effect in typical amounts	Used in very small quantities because of its intense sweetness
Xylitol	Usually smaller response than sugar	Provides some energy and can affect blood glucose
Agave nectar	Can raise blood glucose	Contains sugars despite having a lower GI than table sugar
Honey	Raises blood glucose	Still provides substantial carbohydrate and sugars
Table sugar	Raises blood glucose	Provides readily available carbohydrate

For diabetes management, the glycaemic index of sugar substitutes is best considered together with available carbohydrate, serving size and the other ingredients in the product. A low GI does not automatically mean that a sweetener can be used without considering portion size.

Blood glucose is only one part of the picture. Sweeteners are also frequently discussed in relation to insulin, which requires a little more context.

Do sweeteners affect insulin?

The relationship between sweeteners and insulin is more complex than simply classifying a sweetener as natural, artificial or sugar-free. Insulin responses can depend on the particular sweetener, the amount consumed, other foods eaten at the same time and individual metabolic factors.

Sweeteners that provide little or no available carbohydrate generally do not require the same insulin response as an equivalent amount of conventional sugar. However, this does not mean that every non-nutritive sweetener can be described as having absolutely no effect on insulin under every circumstance. Research into some sweeteners and metabolic responses is still developing.

For practical diabetes management, the carbohydrate content and effect on blood glucose of the complete food or drink are usually more useful than assuming that a sweetener is beneficial or harmful based on its effect on insulin alone.

When considering sweeteners and insulin, avoid assuming that a sweetener has a particular insulin effect simply because it is labelled sugar-free or contains little carbohydrate. Different sweeteners are handled differently by the body, and individual responses can also vary.

For everyday diabetes management, it is generally more practical to consider the sweetener as part of the complete food or drink, including its available carbohydrate and effect on blood glucose.

Overall, sweeteners can affect blood sugar differently depending on their carbohydrate content, how they are metabolised, the amount consumed and the other ingredients in the finished product. Sweeteners that provide little or no available carbohydrate generally have much less direct effect on blood glucose than conventional sugars, while products such as honey, maple syrup and agave still contribute sugars and carbohydrate.

The source of a sweetener does not necessarily predict its effect on blood sugar. The next section looks at natural and artificial sweeteners for diabetics and why both categories contain options with very different nutritional characteristics.

Natural vs artificial sweeteners for diabetics

Sweeteners are often described as natural or artificial, but these labels do not tell us how a product will affect blood sugar. Some natural sweeteners provide little or no available carbohydrate, while others are forms of sugar that can raise blood glucose. Similarly, many artificial sweeteners are used in very small amounts and contribute little carbohydrate.

For people with diabetes, it is therefore more useful to consider the type of sweetener, carbohydrate content, ingredients and portion size rather than assuming that natural automatically means healthier or more suitable.

Natural sweeteners for diabetics

The term natural sweeteners for diabetics can refer to very different products. Stevia and monk fruit are plant-derived high-intensity sweeteners that provide sweetness with little or no available carbohydrate in their pure forms. As discussed earlier, commercial products containing them may include other ingredients, so the finished product still needs to be checked.

Honey, maple syrup, agave and coconut sugar are also commonly described as natural sweeteners. Unlike stevia and monk fruit extracts, however, these products contain sugars and available carbohydrate and can raise blood glucose. Being less refined or derived from a natural source does not remove their carbohydrate content.

This distinction is important when choosing the best natural sweetener for diabetics. Rather than relying on the word “natural”, compare the nutrition information, ingredients, serving size and how much of the product you are likely to use.

Natural sweeteners are therefore not one nutritional category. Some can replace sweetness with very little available carbohydrate, while others behave much more like conventional sugar.

The same principle applies to artificial sweeteners. They should be considered according to their individual characteristics rather than treated as a single group.

Artificial sweeteners for diabetics

Artificial sweeteners for diabetics include high-intensity sweeteners such as sucralose, aspartame and saccharin. Because these sweeteners are much sweeter than sugar, only small amounts are generally needed, and they typically contribute little or no available carbohydrate in normal serving amounts.

Replacing some added sugar with an approved low-calorie or no-calorie sweetener can reduce the amount of sugar and carbohydrate in a food or drink. However, this does not automatically make the complete product nutritious or suitable for unlimited consumption. Other ingredients, total carbohydrate, calories and portion size still matter.

There is also no single best artificial sweetener for type 2 diabetes that suits everyone. Taste, intended use, product formulation and personal preference can all influence which option is most practical.

Artificial sweeteners can provide alternatives to added sugar with little direct effect on blood glucose in typical amounts, but the complete food or drink remains more important than the sweetener alone.

Another useful distinction is whether a sweetener is described as low-calorie or zero-calorie, although these terms also need some context.

Low-calorie vs zero-calorie sweeteners

Low-calorie and zero-calorie sweeteners are sometimes grouped together, but they are not necessarily the same. High-intensity sweeteners such as stevia, sucralose and saccharin are used in such small quantities that they contribute little or no energy in typical servings. Other sugar substitutes, including some polyols, can provide calories but substantially less than conventional sugar.

For people comparing low-calorie sweeteners for diabetics and zero-calorie sweeteners for diabetics, blood sugar impact should not be judged from calories alone. Xylitol, for example, provides energy and can have some effect on blood glucose, while erythritol contributes very little usable energy and generally has little direct effect on blood glucose.

The finished product also matters. A high-intensity sweetener may be virtually calorie-free on its own but sold in a granulated blend containing other ingredients. Checking the nutrition information and serving size gives a clearer picture than relying solely on a “zero-calorie” or “low-calorie” description.

The difference between low-calorie and zero-calorie sweeteners is therefore useful when comparing products, but calorie content alone does not determine their effect on blood glucose. Available carbohydrate and the amount actually consumed also matter.

Check the complete product rather than assuming that every low-calorie or zero-calorie sweetener has the same nutritional profile.

Whether a sweetener is natural or artificial is less important for blood sugar management than its available carbohydrate, portion size and the ingredients in the finished product. Low-calorie and zero-calorie options can help reduce added sugar, but these labels should not be used as the only measure of whether a product is suitable.

This distinction is especially important for honey, maple syrup, agave and other products marketed as natural alternatives to sugar. The next section looks at whether natural sugars are better for diabetics and how they compare with conventional table sugar.

Are natural sugars better for diabetics?

Natural and less refined sugars are often promoted as healthier alternatives to table sugar, but the word “natural” does not mean that a sweetener has little effect on blood glucose. Honey, maple syrup, coconut sugar, agave nectar and date sugar all contain sugars and available carbohydrate.

Some differ from table sugar in their composition, sweetness, glycaemic response or small amounts of other nutrients, but these differences do not make them carbohydrate-free. For people with diabetes, portion size and total carbohydrate remain important when using any of these sweeteners.

Honey

Honey is a natural sweetener made primarily from glucose and fructose, along with water and small amounts of other compounds. It is sweeter than table sugar and has a different nutritional composition, but it still provides a substantial amount of carbohydrate and sugars.

Honey can raise blood glucose, so it should not be treated as a free substitute for sugar simply because it is natural. A smaller amount may sometimes provide the desired sweetness, but the amount used still needs to be considered as part of the overall carbohydrate content of a meal or snack.

Different varieties of honey can also vary in composition, so relying on a single glycaemic index value can be misleading. For practical diabetes management, the serving size and carbohydrate shown on the nutrition information are generally more useful.

Honey can be included in a diabetes-friendly eating pattern in appropriate portions, but it should still be treated as a source of sugars rather than as a sweetener that has little effect on blood glucose.

For a more detailed look at portions, carbohydrate and blood sugar considerations, see honey for diabetics.

Brown sugar

Brown sugar is very similar nutritionally to white table sugar. It is generally made from sucrose with molasses present or added, which gives it its characteristic colour, flavour and moisture.

Although the molasses contributes small amounts of minerals, brown sugar still consists predominantly of sugar and provides a similar amount of carbohydrate to white sugar. It can therefore raise blood glucose and should not be considered a substantially different option for diabetes simply because it is less white or appears less refined.

In cooking and baking, brown sugar may be chosen for its flavour and texture rather than for a meaningful blood sugar advantage. Portion size remains the more important consideration.

Brown sugar can be used in modest amounts if it fits the overall eating pattern, but replacing white sugar with brown sugar does not substantially change the carbohydrate content of a recipe.

For more detail on how it compares with white sugar, see brown sugar for diabetics.

Maple syrup

Maple syrup is produced by concentrating the sap of maple trees. It contains water and naturally occurring compounds, but most of its carbohydrate comes from sugars, particularly sucrose.

Although pure maple syrup contains small amounts of minerals and other compounds, these do not remove its effect on blood glucose. It remains a concentrated source of sugar, so the amount poured over foods or added to recipes can make a meaningful contribution to total carbohydrate intake.

Its strong flavour may allow some people to use a relatively small quantity, but this depends on the food and personal preference. Measuring a serving rather than pouring freely can make the carbohydrate contribution easier to judge.

Maple syrup is a natural sweetener, but nutritionally it should still be considered a source of added sugar. Portion size is therefore more important than its natural origin when considering blood sugar.

For a closer look at its place in a diabetes-friendly diet, see maple syrup for diabetics.

Coconut sugar

Coconut sugar is made from the sap of coconut palm flowers and is often marketed as a less refined alternative to table sugar. It contains predominantly sugars and provides a similar amount of carbohydrate and energy to other caloric sweeteners.

Coconut sugar may contain small amounts of minerals and other compounds, but these do not make it a low-carbohydrate sweetener. Claims about a lower glycaemic index should also be interpreted cautiously because values can vary and a lower GI does not mean that a food will not raise blood glucose.

For people with diabetes, coconut sugar is therefore better treated much like other added sugars. The amount used and the total carbohydrate in the meal or recipe remain the main practical considerations.

Coconut sugar can provide a distinctive flavour, but it does not offer the same blood sugar advantages as sweeteners that contain little or no available carbohydrate.

For more detail on its carbohydrate content and blood sugar considerations, see coconut sugar for diabetics.

Agave nectar

Agave nectar, sometimes called agave syrup, is a sweetener made from the agave plant. It contains a relatively high proportion of fructose, which helps explain why it can produce a lower immediate blood glucose response than sweeteners containing more glucose.

A lower immediate glycaemic response does not mean that agave is carbohydrate-free or automatically a better choice for people with diabetes. Agave still provides sugars and calories, and using large amounts simply because it has a lower glycaemic index can substantially increase total added sugar intake.

For practical purposes, agave is best considered another form of added sugar. Its sweetness may allow a smaller quantity to be used in some foods, but portion size and total carbohydrate still matter.

Agave may affect blood glucose differently from table sugar because of its sugar composition, but this does not make it a free or unlimited sweetener for diabetes.

For a fuller comparison of its fructose content, portions and blood sugar considerations, see can a diabetic eat agave?

Date sugar

Date sugar is usually made by drying whole dates and grinding them into a powder. Unlike refined table sugar, it retains some of the fibre and other components naturally present in the fruit.

However, drying dates concentrates their naturally occurring sugars, so date sugar still provides a substantial amount of carbohydrate. The presence of some fibre does not prevent it from raising blood glucose, particularly when it is used in quantities similar to conventional sugar.

Date sugar also behaves differently from table sugar in recipes because it does not dissolve in exactly the same way. It may be useful for its flavour or as an ingredient in particular foods, but it should not be regarded as a low-carbohydrate sugar substitute.

Date sugar retains more of the whole fruit than highly refined sugar, but it is still a concentrated source of carbohydrate and sugars. Portion size therefore remains important for people managing blood glucose.

For more detail on its nutritional profile and practical use, see date sugar for diabetics.

Natural sugars can differ in flavour, processing and composition, but they still contribute sugars and carbohydrate that can affect blood glucose. Honey, maple syrup, coconut sugar, agave, brown sugar and date sugar should therefore not be considered automatically better for diabetes simply because they are described as natural or less refined.

The most appropriate choice depends on the amount used, the total carbohydrate in the food or meal and the overall eating pattern. For people looking to reduce added sugar, a sugar substitute with little or no available carbohydrate may sometimes be more practical.

The next section looks at how to choose a sugar substitute for diabetes, including what to check on the ingredients list and nutrition information.

How to choose a sugar substitute for diabetes

Choosing a sugar substitute for diabetes involves more than comparing how sweet different products taste. Sweeteners vary in carbohydrate content, ingredients, serving size and suitability for drinks, cooking or baking. Products based on the same sweetener can also have different nutritional profiles depending on what else has been added.

The nutrition information and ingredients list can therefore be more useful than claims such as “sugar-free”, “natural” or “zero calorie” on the front of the package.

Check carbohydrates and added sugars

Start by checking the total carbohydrate and sugars in the nutrition information. Pure high-intensity sweeteners may contribute very little carbohydrate, but granulated and powdered products often contain additional ingredients to provide bulk and make them easier to measure.

Ingredients such as dextrose and maltodextrin can contribute carbohydrate even when the main sweetener itself has little direct effect on blood glucose. Sugar alcohols may also appear in sweetener blends and can differ in how they are absorbed and metabolised.

The ingredients list is particularly useful because products marketed under the same type of sweetener can have quite different formulations.

When comparing sugar substitutes, consider the carbohydrate content of the complete product rather than judging it solely by the sweetener named on the front of the package.

Check the serving size

Serving size can make a significant difference when interpreting sweetener labels. High-intensity sweeteners may be used in drops or very small quantities, while granulated sugar substitutes designed to replace sugar in recipes may be used by the spoonful or cup.

A product may contain only a small amount of carbohydrate per labelled serving, but using several servings can increase the total. This is particularly relevant with products containing carbohydrate-based bulking ingredients.

When comparing products, look at both the carbohydrate per serving and the amount you are realistically likely to use.

Checking serving size alongside total carbohydrate gives a more useful picture of how a sweetener fits into a meal or recipe than looking at the headline nutrition claims alone.

Consider how you will use it

The best sugar substitute can also depend on what you are making. A sweetener that works well in tea or coffee may not provide the bulk, moisture or texture needed to replace sugar in baking.

High-intensity sweeteners such as stevia and sucralose can provide sweetness in very small quantities, while sugar alcohols and other alternatives may provide more of the volume associated with sugar. Some sweeteners also tolerate prolonged heating better than others.

Taste matters as well. Stevia, saccharin and some other sweeteners can have noticeable aftertastes for some people, while sugar alcohols may produce a cooling sensation. Trying a small quantity before using a new sweetener throughout a recipe can be helpful.

Choose a sweetener according to its intended use rather than looking for one product to replace sugar in every situation. Drinks, everyday foods and baking can each require different properties.

Watch for blended sweeteners

Many commercial sweeteners are blends rather than a single ingredient. Stevia or monk fruit, for example, may provide most of the sweetness while erythritol, dextrose, maltodextrin or another ingredient provides the bulk.

Blending is not necessarily a problem. It can improve taste, texture and ease of use. However, it means that two products carrying the same sweetener name on the front of the package may differ in calories, carbohydrate content and potential effect on blood glucose.

This is particularly important with products designed as spoon-for-spoon or cup-for-cup replacements for sugar because they are consumed in much larger quantities than concentrated sweetener extracts.

When choosing a blended sweetener, read the full ingredients list and nutrition information rather than assuming that all products containing stevia, monk fruit or another low-calorie sweetener are nutritionally equivalent.

These differences become especially important when sugar substitutes are used in larger quantities for cooking and baking, which the next section looks at in more detail.

A suitable sugar substitute for diabetes should fit both the nutritional needs of the diet and the way the product will actually be used. Checking total carbohydrate, serving size and the full ingredients list can help identify differences that may not be obvious from claims on the front of the package.

There is no single sweetener that works best in every situation. This is particularly noticeable in cooking and baking, where sugar contributes more than sweetness. The next section looks at sweeteners for baking and cooking and what to consider when replacing sugar in recipes.

Sweeteners for baking and cooking

Choosing sweeteners for baking and cooking involves more than finding an alternative with the same level of sweetness as sugar. In many recipes, sugar also contributes volume, structure, moisture, browning and texture, so removing it can change the finished food even when sweetness is successfully replaced.

Different sugar substitutes behave differently when heated. Some provide bulk and can be used in larger quantities, while high-intensity sweeteners such as stevia require only a very small amount. The most suitable choice therefore depends on the recipe as well as its carbohydrate content.

Best sweeteners for baking

The best sweeteners for baking depend on whether the recipe needs only sweetness or also requires the bulk and texture normally provided by sugar. Erythritol and other granulated sugar substitutes can provide more volume than concentrated high-intensity sweeteners, which can make them easier to use in some cakes, biscuits and desserts.

Allulose also has useful sugar-like properties in baking, including the ability to brown and retain moisture. However, as discussed earlier, its availability and regulatory status vary by country.

High-intensity sweeteners such as stevia and sucralose can also be used in baking when the particular product is suitable for heating. Because only small quantities are required, however, they do not replace the physical volume of sugar and may require adjustments to the recipe.

There is therefore no single diabetic-friendly baking substitute that works best in every recipe. The choice depends on sweetness, bulk, texture, heat stability and the other ingredients being used.

Replacing sugar in recipes

Replacing sugar is not always a simple one-for-one substitution. Removing a significant amount of sugar can affect the moisture, tenderness, spread, browning and overall structure of cakes, biscuits and other baked foods.

Granulated sugar substitutes designed as cup-for-cup or spoon-for-spoon replacements can make substitution easier, but their ingredients and carbohydrate content should still be checked. Concentrated sweeteners such as stevia require much smaller quantities, so recipes may need other adjustments to compensate for the volume that has been removed.

It is also important to consider the complete recipe. Replacing sugar with a low-carbohydrate sweetener does not automatically make a cake, biscuit or dessert low in carbohydrate because flour, fruit, chocolate, milk and other ingredients may still contribute substantial amounts.

When replacing sugar in cooking or baking, follow the manufacturer’s instructions for the particular sweetener and consider how the substitution will affect both the recipe and its overall carbohydrate content.

A successful substitution should therefore account for both the function of sugar in the recipe and the nutritional effect of the replacement. Simply exchanging sweetness does not necessarily produce the same texture, cooking result or carbohydrate content.

When choosing sweeteners for baking and cooking, consider how the sweetener behaves in the recipe as well as its carbohydrate content. Sweetness, bulk, moisture, texture and heat stability can all affect the finished result, and a substitute that works well in drinks may not work equally well in baking.

Replacing sugar can help reduce added sugar and carbohydrate, but the nutritional value of the finished food still depends on the complete recipe and portion size. It is also worth considering how much sweetener is being used overall, which the next section looks at in more detail.

How much sweetener can a diabetic have?

There is no single amount of sweetener that is appropriate for everyone with diabetes. The amount that can be included depends on the type of sweetener, how often it is consumed, the serving size and whether the product contains other ingredients that contribute carbohydrate or calories.

Sweeteners that have little direct effect on blood glucose should not automatically be considered suitable in unlimited amounts. Approved high-intensity sweeteners have established safety limits known as an Acceptable Daily Intake (ADI). The ADI represents an amount that can be consumed daily over a lifetime without appreciable health risk and includes a substantial safety margin.

For most people, normal dietary use of approved sweeteners is well below these limits. Rather than trying to consume up to an ADI, it is more useful to regard it as a safety threshold and use sweeteners in sensible amounts as part of an overall balanced diet.

Sugar alcohols, or polyols, require a different consideration. Larger amounts of xylitol, erythritol, sorbitol and some other polyols can cause digestive symptoms such as bloating, gas or diarrhoea in some people. Individual tolerance varies, and symptoms may become more noticeable as the amount consumed increases.

Products containing sweeteners can also contribute other ingredients. A food labelled sugar-free, for example, may still contain carbohydrate, calories or substantial amounts of fat, so the complete nutrition information and portion size remain important.

Sweeteners can be useful for reducing added sugar, but they are best used as one part of a diabetes-friendly eating pattern rather than as something that needs to be consumed in large amounts. Check the serving size and ingredients, consider your tolerance to sugar alcohols and follow any product-specific guidance.

For approved high-intensity sweeteners, normal dietary use is generally more relevant than trying to calculate the maximum ADI. If individual blood glucose responses are a concern, monitoring the complete food or drink can also be more informative than considering the sweetener in isolation.

Frequently asked questions

These common questions cover some of the practical points people often consider when choosing sweeteners for diabetics, including blood sugar effects, artificial sweeteners, sugar alcohols and everyday use.

Can diabetics use sweeteners?

Yes. People with diabetes can use a range of low-calorie and no-calorie sweeteners as alternatives to added sugar. Many provide little or no available carbohydrate in typical serving amounts and can therefore help reduce the carbohydrate contributed by sugar.

However, the complete product still matters. Some sweetener blends contain other ingredients that contribute carbohydrate, so checking the nutrition information and ingredients list is useful.

Can diabetics eat artificial sweeteners?

Approved artificial sweeteners such as sucralose, aspartame and saccharin can generally be included in a diabetes-friendly diet when consumed within established safety limits. Because they are much sweeter than sugar, only small amounts are usually needed.

Replacing added sugar with an artificial sweetener can reduce sugar and carbohydrate intake, but it does not automatically make the complete food or drink a healthier choice. Other ingredients and portion size still need to be considered.

What is the best sugar substitute for diabetics?

There is no single best sugar substitute for diabetics for every situation. Stevia and monk fruit can work well when only a small amount of intense sweetness is needed, while erythritol and some other alternatives provide more bulk for certain recipes.

The best choice depends on carbohydrate content, ingredients, taste, intended use and individual preference. For baking, the sweetener also needs to provide the properties required by the recipe.

Which sweetener does not raise blood sugar?

Pure forms of stevia, monk fruit, erythritol and several high-intensity artificial sweeteners generally have little direct effect on blood glucose because they provide little or no available carbohydrate in typical amounts.

However, commercial products can contain additional ingredients such as dextrose, maltodextrin or other sweeteners. People looking for sweeteners that don’t raise blood sugar should therefore check the complete product rather than relying only on the sweetener named on the package.

Are zero-calorie sweeteners better for diabetics?

Zero-calorie sweeteners can be useful when they replace added sugar because they can reduce the amount of sugar, carbohydrate and sometimes calories in a food or drink. This can make them practical options for people managing blood glucose.

However, zero calories does not automatically mean that a product is nutritionally better. The overall food or drink, ingredients, portion size and eating pattern are more important than the calorie content of the sweetener alone.

Is a natural sweetener better than an artificial sweetener for diabetes?

Not necessarily. The terms natural and artificial describe the source or production of a sweetener, but they do not by themselves determine its effect on blood glucose.

Plant-derived sweeteners such as pure stevia and monk fruit generally provide little available carbohydrate, but natural sweeteners such as honey, maple syrup and agave contain sugars that can raise blood glucose. Artificial sweeteners such as sucralose, aspartame and saccharin generally contribute little carbohydrate in typical amounts.

Can diabetics use sweeteners every day?

Approved low-calorie and no-calorie sweeteners can generally be used regularly within established safety limits. They can be one way to reduce added sugar, particularly when replacing sugar in drinks and other frequently consumed foods.

Regular use does not mean unlimited use is necessary or beneficial. Variety, the overall quality of the diet and the amount of sweet-tasting food and drink consumed should also be considered.

Are sugar alcohols safe for diabetics?

Sugar alcohols, also known as polyols, can generally be included in a diabetes-friendly diet, but they do not all affect the body in the same way. Erythritol generally has little direct effect on blood glucose, while xylitol, maltitol and some other polyols can contribute varying amounts of energy and available carbohydrate.

Larger amounts of some sugar alcohols can also cause bloating, gas or diarrhoea. Portion size, individual tolerance and the carbohydrate content of the complete product should therefore be considered.

Are sugar-free sweeteners and foods always better for diabetics?

No. A product labelled sugar-free may contain very little sugar, but this does not necessarily mean that the food contains little carbohydrate or few calories. Sugar-free foods may still contain starches, flour, sugar alcohols, fats or other ingredients that affect their overall nutritional profile.

Check the total carbohydrate, serving size and ingredients rather than relying on the sugar-free claim alone. This is particularly important for biscuits, cakes, chocolate, desserts and other foods where replacing sugar does not remove the carbohydrate contributed by other ingredients.

Sweeteners can provide useful alternatives to added sugar, but there is no single option that is best for everyone with diabetes. The type of sweetener, available carbohydrate, serving size, ingredients and intended use all help determine which choice is most appropriate.

The wider diet remains more important than any individual sweetener. Using sugar substitutes selectively, while continuing to consider overall carbohydrate intake, portion size and food quality, is a more practical approach than focusing on whether one sweetener is simply “good” or “bad” for diabetes.

Final takeaway

Sweetener choices for diabetes do not depend on finding one perfect sugar substitute or avoiding all sweet-tasting foods. The most useful approach is to choose sweeteners that suit your individual needs while considering available carbohydrate, portion size, ingredients and how the product affects your blood glucose.

Options such as stevia for diabetics, monk fruit for diabetics, erythritol for diabetics, xylitol for diabetics and sucralose for diabetics can all have different properties and practical uses. Some provide little or no available carbohydrate in typical amounts, while others can contribute carbohydrate, calories or additional ingredients that need to be considered.

Natural alternatives such as honey for diabetics, maple syrup for diabetics, coconut sugar for diabetics and agave for diabetics also require a different approach because being natural does not mean that they are free from sugars or that they will have little effect on blood glucose.

In practice, aim for sweetener choices that are enjoyable, practical and appropriate for your overall eating pattern while keeping added sugar and total carbohydrate in context.
