In this article, we will explore into the truth behind erythritol, exploring its potential side effects, its impact on oral health, and whether it truly is a healthier alternative to sugar. Stay informed and discover the reality behind this seemingly perfect sweetener.

What Exactly is Erythritol?

Erythritol is a type of sugar alcohol that is used as a sugar substitute . It is found naturally in some fruits and vegetables, and it is also produced commercially through a fermentation process. Erythritol is about 60-70% as sweet as sugar, but it has almost no calories. This makes it a popular ingredient in sugar-free and low-calorie foods and drinks.

Erythritol: Origins and Production

The sugar alcohol erythritol belongs to a class of compounds used as low-calorie sweeteners. It is naturally found in fruits and vegetables but is primarily produced through the fermentation of glucose from corn or wheat starch by yeast. The final product is a powdery white crystal.

Erythritol has a two-fold origin story: natural occurrence and commercial production.

Natural Origins:

  • Erythritol exists in small amounts in some fruits and vegetables like pears, melons, and mushrooms.
  • It’s also produced naturally by some organisms as a way to deal with stressful environments, like high salt conditions .

Commercial Production:

  • Today, erythritol isn’t extracted from fruits and vegetables due to inefficiency.
  • Instead, it’s mass-produced through fermentation, a process similar to yogurt or beer making.
  • In fermentation, specific yeasts or fungi (like Moniliella pollinis) feed on sugary sources (often corn-derived glucose) and convert them into erythritol.

Here’s a breakdown of the production process:

  1. Starch Breakdown: Starch from corn undergoes enzymatic hydrolysis to create glucose.
  2. Fermentation: Yeast or fungi cultures ferment the glucose, producing erythritol.
  3. Purification: After fermentation, the erythritol is separated and purified from the other byproducts.

Chemical Production (Not Common):

  • While less common, erythritol can also be produced chemically, but this method is not cost-effective for large-scale production 

Properties and Uses of Erythritol.

What sets erythritol apart from other sugar alcohols is its extremely low calorie content – just 0.24 calories per gram compared to table sugar’s 4 calories per gram. Despite this, it provides 70% of the sweetness of sugar. It is safe in moderate amounts, being mostly absorbed into the bloodstream and excreted in the urine. Erythritol is a suitable alternative for those with diabetes as it does not spike blood sugar levels.

Plus, erythritol may benefit dental health by inhibiting the growth of harmful oral bacteria, leading to potential improvements in oral hygiene compared to other sugar alcohols. Erythritol boasts several interesting properties that make it a valuable ingredient in the food industry.

Here’s a breakdown of its key characteristics and how they translate into various uses:

Properties of Erythritol:

  • Low Calorie: Most of the ingested erythritol isn’t metabolized by the body, resulting in minimal calorie contribution (around 0.24 calories per gram). This makes it ideal for sugar-free and low-calorie products.
  • Sweetener: Erythritol offers sweetness levels around 60-70% compared to sugar. It blends well with other high-intensity sweeteners to achieve a more sugar-like taste profile.
  • Tooth-Friendly: Unlike sugar, erythritol isn’t broken down by oral bacteria, preventing tooth decay and promoting dental health.
  • Sugar Alcohol: As a sugar alcohol, erythritol offers a slight cooling effect when consumed, which can be desirable in certain foods like mints or chewing gum.
  • High Digestibility: Compared to other sugar alcohols, erythritol is well-absorbed by the body and causes minimal digestive issues at recommended intake levels.

Uses of Erythritol:

  • Sugar Substitute: Erythritol’s primary application is as a sugar substitute in various food and beverage categories. It finds its way into:
    • Sugar-free drinks (coffee, tea, sodas)
    • Sugar-free confections (candy, chocolate)
    • Baked goods (cookies, cakes)
    • Tabletop sweeteners
    • Sugar-free chewing gum
  • Bulking Agent: Due to its bulking properties similar to sugar, erythritol can add volume and texture to foods without adding significant calories.
  • Flavor Enhancer: Erythritol can help enhance the overall flavor profile of foods by reducing bitterness and creating a more rounded taste.

Here Are Some of The Benefits of Erythritol:

    • Low in Calories: Erythritol contains almost no calories, making it a great option for people trying to lose weight or manage their calorie intake. This is because most of the ingested erythritol isn’t metabolized by the body and is excreted through urine.

    • Does not Raise Blood Sugar Levels: Erythritol does not raise blood sugar levels, making it a good option for people with diabetes or prediabetes. This is because the body does not absorb erythritol in the same way that it absorbs sugar.

    • Tooth-Friendly: Unlike sugar, erythritol does not promote tooth decay. In fact, some studies have shown that erythritol may actually help to prevent cavities. This is because erythritol does not feed the bacteria in the mouth that cause cavities.

    • May Help Reduce Calorie Intake: Erythritol may help reduce calorie intake by reducing appetite and cravings. Some studies have shown that erythritol can help people feel fuller for longer after eating.

    • Fewer Gastrointestinal Side Effects: Compared to other sugar alcohols, erythritol is well-absorbed by the body and causes minimal digestive issues at recommended intake levels. This is because most of the erythritol is absorbed in the small intestine and excreted through urine.

However, There Are Also Some Potential Downsides to Erythritol:


Erythritol, while offering potential benefits, isn’t without drawbacks. Here are some downsides to consider:

  • Digestive Issues: Despite being better absorbed than other sugar alcohols, consuming large quantities of erythritol can lead to bloating, gas, and diarrhea, especially for those with sensitive digestive systems.
