As I mentioned in a recent blog post, I was diagnosed with LADA a few months ago. This has led me to make a massive change to my dietry habits. Although I’ve been vegetarian and a healthy eater for almost my entire adult life (I’m now in my mid-late fifties), I’ve recently slashed my carb and sugar intake to almost nil.
That being said, I still enjoy baking and eating sweet things – I’ve merely swapped cane sugar with alternative natural sweetners that don’t spike my blood sugar levels.
When it comes to baking, just like with alternative flours, some sugar substitutes are more suitable than others depending on the recipe that’s being made. Read on to discover which alternative natural sweeteners are best to use in which scenarios.
Any ingredient links that are highlighted in yellow I’ve bought and cooked with myself – so I can personally recommend the product and the brand.

Pros & cons of different alternative natural sweeteners
Allulose
Allulose is a rare sugar naturally found in small amounts in foods like figs, raisins, wheat and maple syrup. It’s a low-calorie sweetener that closely resembles the taste and texture of regular sugar but with a significantly lower impact on blood glucose and insulin levels.
Here’s a breakdown of its nutritional values, functions in food and specific applications in low-carb and keto recipes:
Nutritional value
- Calories: Allulose has approximately 4 calories per gram (about 1/10th the calories of regular sugar).
- Carbohydrates: While technically a carbohydrate, it’s not metabolised by the body in the same way as traditional sugars.
- Net carbs: For this reason, the FDA permits allulose to be excluded from the “Total Sugars” and “Added Sugars” on Nutrition Facts labels and considered to have zero net carbs.
- Impact on blood sugar: It doesn’t significantly raise blood sugar or insulin levels, making it suitable for individuals managing diabetes or following low-carb diets.
Functions in low-carb & keto recipes
Allulose offers several advantages when used in low-carb and keto recipes as a sugar substitute:
- Taste and texture: It closely mimics the taste and texture of sugar without the usual aftertaste often associated with artificial sweeteners.
- Baking and cooking: It browns and caramelises like conventional sugar, making it ideal for baked goods and other recipes where browning is desirable.
- Bulking agent: It provides bulk and moisture to recipes, ensuring the right texture and mouthfeel in cakes, cookies and ice cream.
- Freezing properties: It performs well in refrigerated or frozen applications, helping create smooth and scoopable ice cream.
Applications
You can use allulose as a 1:1 substitute for sugar in various low-carb and keto recipes, including:
- Baked goods (cakes, cookies, muffins, etc.)
- Frozen desserts (ice cream, sorbet)
- Beverages (coffee, tea, smoothies)
- Sauces, jams and syrups
- No-bake treats (energy balls, mousse, puddings)
Potential downsides
While generally considered safe by the FDA, some individuals may experience gastrointestinal upset, like bloating, gas or diarrhoea, when consuming large amounts of allulose. Starting with smaller amounts and observing individual tolerance is recommended.
Cost
Allulose is more expensive than table sugar and some other sweeteners.
Important Note: While allulose is a promising alternative for low-carb and keto recipes, www.levels.com says long-term human studies are still ongoing to fully understand all its potential benefits and risks. If you have any underlying health conditions or concerns, it’s always best to consult with a healthcare professional before incorporating allulose or any new sweetener into your diet.
Erythritol
Erythritol is a popular sugar alcohol used as a sweetener, especially in low-carb and keto recipes. It’s naturally found in some fruits and fermented foods.
Here’s a breakdown of its nutritional values, functions in food and specific applications in low-carb and keto recipes:
Nutritional value
- Calories: Erythritol has a very low-calorie count, approximately 24 calories per gram, making it almost calorie-free.
- Carbohydrates: Erythritol technically contains 4 grams of carbohydrates per teaspoon. However, it’s poorly absorbed by the body and doesn’t impact blood sugar levels like regular carbohydrates. Therefore, it is generally considered to have zero net carbs, especially for those following a keto diet.
- Glycaemic index (GI): Erythritol has a GI of 0, meaning it does not affect blood sugar or insulin levels.
Functions in low-carb & keto recipes
Erythritol is a versatile sweetener and offers several advantages in low-carb and keto recipes:
- Sweetness: It’s about 60-80% as sweet as table sugar. You might need to adjust the amount used depending on your desired sweetness level, with some recommending using approximately 1 1/3 cups of erythritol for each cup of sugar.
- Baking and cooking: Erythritol behaves similarly to sugar in many recipes, particularly baked goods. However, it’s important to note that erythritol doesn’t brown or caramelise like sugar, which may result in a different appearance in some baked goods. It also doesn’t dissolve as readily as sugar and can create a slightly gritty texture.
- Bulk and texture: Erythritol can add bulk and moisture retention to baked goods, contributing to a better texture in reduced-sugar and sugar-free formulations.
- Freezing point depression: Erythritol, due to its small molecular size, has a greater effect on lowering the freezing point of solutions compared to sugar. This can be helpful in creating smooth and scoopable low-carb and keto ice cream recipes. However, too much erythritol can depress the freezing point too far, resulting in a product that may be difficult to freeze completely. Some users have reported that erythritol can make ice cream freeze harder and icier.
- Flavour profile: Erythritol has a clean sweetness, but some people might notice a cooling sensation on the tongue, especially when used in larger amounts.
Applications in low-carb and keto recipes
- Erythritol can be used in a variety of low-carb and keto recipes, including:
- Baked goods (cakes, cookies, muffins)
- Frozen desserts (ice cream)
- Drinks (coffee, tea, smoothies)
- Sauces, jams and dressings
- Sugar-free sweets and candies
Important considerations
- Digestive tolerance: While erythritol is generally well-tolerated, consuming large amounts might cause digestive discomfort like bloating, gas or diarrhoea, though less likely than other sugar alcohols.
- Texture in frozen desserts: When using erythritol in frozen desserts, it’s important to be mindful of its effect on the freezing point and potential for hardening or crystallisation upon freezing. You might need to experiment with amounts or consider combining it with other sweeteners like allulose for desired results. According to Reddit users, some have found xylitol or a blend of allulose and stevia to be more effective in preventing hardening in low-carb ice creams.
- Cost: Erythritol can be more expensive compared to traditional sugar.
Note: While erythritol is often considered a safe and effective sugar substitute for keto and low-carb diets, it’s essential to be mindful of individual tolerances and potential effects on texture, particularly in frozen desserts. It’s always best to start with smaller amounts and adjust according to your preferences and body’s response.
Inulin
Inulin is a soluble dietary fibre, commonly extracted from chicory root, that has gained popularity in low-carb and keto recipes due to its unique properties. It’s a type of fructan, meaning it’s composed of fructose molecules, but it’s not fully digested by the human body.
Nutritional highlights
- Low calorie: Inulin contributes approximately 5 calories per gram, significantly fewer than sugar.
- Low carbohydrate: Inulin is largely indigestible by the human body, so its carbohydrates don’t get absorbed. This means it doesn’t significantly affect blood sugar levels, making it suitable for low-carb and ketogenic diets.
- High fibre: Inulin is an excellent source of dietary fibre, with some products providing up to 90g of fibre per 100g.
- Prebiotic effects: Inulin is a prebiotic, meaning it feeds the beneficial bacteria in the gut, which can improve gut health, says Healthline.
Functions in low-carb & keto recipes
- Sweetening: Inulin has a mild, subtle sweetness, about 10-15% the sweetness of sugar. It can be used to replace a portion of sugar in recipes, especially when paired with other sweeteners.
- Texture & mouthfeel: Inulin can significantly improve the texture and mouthfeel of low-carb baked goods. It absorbs moisture, creating a creamy and softer crumb, which can be particularly beneficial in cakes, muffins and breads.
- Fat replacement: Inulin’s creamy texture when dissolved in liquid allows it to be used as a partial fat replacement, contributing to “lighter” baked goods and lower-fat products like cheeses and sauces.
- Bulking agent: Inulin acts as a bulking agent, adding density and volume to recipes without adding carbohydrates or calories. This is especially helpful in low-carb baking where alternative flours might result in a denser product.
- Digestive benefits: As a prebiotic fibre, inulin helps support a healthy gut microbiome, which can be beneficial for overall digestion and health.
- Satiety: Due to its fibre content and ability to swell when mixed with liquid, inulin can help increase feelings of fullness, potentially assisting with weight management.
Applications
Inulin can be used in a variety of low-carb and keto applications, such as:
- Baking (cakes, cookies, muffins, breads)
- Smoothies and beverages
- Sauces and glazes
- Yoghurt and dairy products
- Sugar-free confectionery
Important considerations
- Digestive tolerance: It’s crucial to introduce inulin gradually into your diet as high intake can lead to gas, bloating, stomach cramps and diarrhoea, especially for those sensitive to FODMAPs.
- Sweetness intensity: Remember that inulin is not as sweet as sugar, so you may need to adjust the quantities or combine it with other keto-friendly sweeteners like erythritol or monk fruit, depending on the recipe and desired sweetness level.
- Texture: While it generally improves texture, a study suggests the degree of polymerisation of inulin can affect the final texture of baked goods. Experimentation might be needed to find the optimal ratio for your desired outcome.
- Not a complete sugar replacement: Inulin cannot fully replace sugar in baking as it doesn’t caramelise or provide the same browning properties. Partial substitution (up to 20-30%) is a more realistic approach, according to tannov.com.
- Check ingredients: When buying inulin products, always check the label for potential added ingredients that might impact the nutritional value or suitability for a keto diet.
By incorporating inulin thoughtfully into your low-carb and keto recipes, you can enhance both the nutritional profile and the texture of your meals and treats.
