Stevia vs. Erythritol: Which Sugar Alternative Is Best?

Posted Oct 18, 2023 Updated Apr 15, 2024

As consumers, we've become more aware of our dietary choices and their effects on our bodies. As a result, the search for healthier sugar alternatives has become an important topic of debate and discussion. In recent years, many contenders have risen to prominence. But today, we're embarking on a comparative exploration between two of the most buzzed-about sugar substitutes: Stevia and erythritol. With help from OLIPOP’s own Registered Dietitian, let’s investigate these two sugar alternatives…

What Is Stevia?

Stevia, a naturally occurring sugar alternative, has captivated health-conscious consumers for years. Derived from the leaves of the South American Stevia rebaudiana plant, this sugar substitute boasts a centuries-old origin story. Indigenous communities in Paraguay and Brazil have used Stevia leaves as a sweetener for generations, valuing it as both a sweetener and a medicinal herb.

This natural origin sets Stevia apart from many other sugar alternatives, evoking an earthy, botanical charm. The sweetness in Stevia comes from compounds called steviol glycosides, primarily stevioside and rebaudioside. These can be up to 300 times sweeter than traditional sugar, ensuring that a little goes a long way. In recent years, Stevia has gained popularity as a sugar alternative in various products, from teas and health-conscious sodas like OLIPOP, to baked goods and dietary supplements.

What Is Erythritol?

Erythritol, on the other hand, is an artificial sweetener that comes from a family of sugar alcohols. Don't let the name mislead you; it doesn't have the intoxicating effects of alcohol but rather belongs to a class of compounds known as polyols. Erythritol is primarily manufactured through a fermentation process involving yeast and glucose from corn or wheat starch.

The result? A white, crystalline powder with a taste profile that attempts to mimic sugar's sweetness. Erythritol provides about 70% of the sweetness of sugar, making it less potent than Stevia. It also has the added advantage of being nearly calorie-free, as the human body cannot metabolize it efficiently. This has catapulted it to the forefront of sugar substitutes.

Stevia vs Erythritol

Nutritional Value

When it comes to their nutritional value, Stevia and erythritol have several similarities. Stevia is a nutritional minimalist, offering next to zero calories, carbohydrates, and nutrients. It's essentially a sweet ghost, providing sweetness without any substantive nutritional baggage. This makes it a favorite among those who need to watch their calorie and carbohydrate intake, such as individuals with diabetes or those on a ketogenic diet.

Erythritol, while still low in calories, has a slightly more complex nutritional profile. It provides around 0.2 calories per gram, and it doesn't contribute to net carbohydrate or sugar intake since the human body absorbs it very poorly. Additionally, erythritol doesn't contain any vitamins or minerals, so it brings very few nutritional benefits to the table.

Effects on Blood Sugar

One of the critical considerations when choosing a sugar alternative is its impact on blood sugar levels. Stevia, with its negligible carbohydrate content, is a top choice for people looking to maintain stable blood sugar. It does not raise blood sugar levels, making it a suitable option for diabetics and those following low-carb diets.

Erythritol also shines in this department. Despite its sweet taste, erythritol doesn't significantly affect blood sugar levels. Because the body absorbs but doesn't metabolize it, it passes through the digestive system virtually unchanged, leading to minimal or no increase in blood glucose. This also makes erythritol a safe choice for those watching their blood sugar.

Caloric Impact

Erythritol and Stevia both earn points for their low-calorie count, making them favorites among those watching their intakes. Erythritol contributes only about 0.2 calories per gram compared to the 4 calories per gram of sugar. Stevia, while low in calories as well, doesn't quite match erythritol's calorie-free status.

Uses in Foods & Beverages

Erythritol measures more like sugar and caramelizes when exposed to heat. This means that baking enthusiasts might find erythritol more accommodating in recipes that depend on sugar's structural properties. Stevia, by contrast, is often preferred by those looking for food and drinks derived from natural sources, like our selection of delicious healthy sodas at OLIPOP. 

Erythritol Side Effects: Is Erythritol Safe?

As with any sugar substitute, it's vital to scrutinize potential side effects. Erythritol, although generally recognized as safe by health authorities like the FDA and WHO, can lead to digestive discomfort when consumed in excess. Some individuals may experience gas, bloating, or diarrhea, especially if they have a sensitivity to sugar alcohols. However, these side effects tend to be less severe compared to other sugar alcohols like xylitol.

However, in a recent study conducted by Nature Medicine, researchers suggest that elevated levels of erythritol could cause blood clotting, stroke, heart attack, and death. Particularly for those with diabetes, high levels of erythritol in the blood nearly doubled the likelihood of heart attacks and strokes. By contrast, Stevia, derived from a natural plant source, has a reputation for being gentler on the digestive system and seems to pose nearly no health risks. It is also noteworthy that the body can produce erythritol, so dietary intake may not be completely to blame. 

Stevia vs. Erythritol: The Takeaway

In this sugar substitute showdown between Stevia and erythritol, these two contenders both have broad appeal. Stevia's natural origin and intense sweetness charm many, while erythritol's resemblance to sugar and near zero-calorie allure make it a formidable opponent. However, the potential health risks of erythritol and its artificial origins make this sweetener less appealing to our OLIPOP team. This is why we chose Stevia as our sugar substitute of choice.

In your own daily life, deciding between these two sugar alternatives ultimately rests on your taste buds, dietary needs, and how your body responds to these sugar substitutes. As you navigate the culinary landscape of healthier choices, these sweeteners stand ready to transform your recipes and redefine your relationship with sweetness, one delectable sip at a time.
