Sucralose vs. Stevia: The Pros & Cons - Herbaly

November 03, 2023

In the world of sweeteners, the debate between sucralose and stevia stands out. Each has its own group of devoted followers, and each holds a unique place in the world of food and beverages. Making a choice between these two popular sweeteners can be a bit perplexing. This article aims to demystify the cloud of questions surrounding sucralose and stevia, shedding light on their origin, production, benefits, and drawbacks. 

What Is Sucralose?

Sucralose is a synthetic sweetener created in a laboratory by altering the chemical structure of sugar. By replacing certain atoms with chlorine atoms, a compound is formed that's approximately 600 times sweeter than sugar — without the calories. Sucralose is a widespread choice in a range of low-calorie and sugar-free food and beverage products.

How Is Sucralose Sourced?

The manufacturing of sucralose involves a multi-step chemical process. It starts with sucrose, and, through a series of reactions involving chlorine, it's transformed into a stable, sweet compound. This artificial sweetener is heat stable, making it suitable for cooking and baking, adding to its versatility and popularity in the food industry.

What Are the Pros and Cons of Sucralose?

Pros of Sucralose include its zero-calorie content and its ability to withstand high temperatures, making it a suitable option for those looking to reduce their caloric intake and still enjoy sweet flavors in cooked or baked goods. It does not affect blood glucose levels, making it a low-calorie option for those managing diabetes or seeking weight loss.

However, the cons deserve attention, too. Concerns have been raised regarding the potential impact of sucralose on gut health, as research suggests that sucralose may alter the gut microbiota and lead to digestive issues. 

Additionally, some people may experience digestive discomfort, such as bloating and gas, when consuming products sweetened with sucralose. The taste can also be off-putting to some, as it may leave a lingering artificial aftertaste.

Another worry is its environmental impact. The production process is chemical-intensive, and the compound itself is not biodegradable, raising concerns about long-term environmental harm to bacteria. 

What Is Stevia?

As a natural counterpart, Stevia is a sweetener that originates from the leaves of the Stevia rebaudiana plant. Contrasting with the synthetic origin of sucralose, Stevia’s natural roots trace back to South America, where it has been used for centuries for its sweet properties and various medicinal benefits. The compounds responsible for its sweetness are steviol glycosides, which are notably potent, delivering a sweetness punch that can be up to 300 times that of sugar.

How Is Stevia Sourced?

Sourcing stevia stands as a more environmentally gentle process. The plant is cultivated, and upon maturity, its leaves are harvested and dried. The extraction involves steeping these dried leaves in water. The resulting liquid is filtered and purified to collect the sweet compounds, maintaining its natural essence throughout the process.

What Are the Pros and Cons of Stevia?

Stevia’s benefits subtly shine in this debate. As a zero-calorie sweetener, it echoes the calorie-free advantage of sucralose but in a natural form. Its non-impact on blood glucose levels also makes it a friend to those managing diabetes and/or obesity. Stevia is similar to sucralose but without many of the accompanying concerns about gut health and digestive discomfort.

Just like any other product, Stevia also has some minor downsides. Some users report a unique aftertaste, described as slightly bitter (think: licorice), which may not appeal to everyone. The potent sweetness also requires careful measurement to ensure the right balance in foods and beverages.

How Do Sucralose and Stevia Compare as Sweeteners?

Now that we’ve explored the characteristics, sourcing, pros, and cons of both Sucralose and Stevia, let’s delve deeper into a comparative analysis to understand their positions more distinctly in the panorama of sweeteners.

Sweetness Intensity and Flavor Profile

Sucralose, lab-crafted, flaunts an intense sweetness, almost 600 times sweeter than regular sugar. This intensity allows for minimal use, but some people find its lingering artificial aftertaste less appealing. In contrast, stevia, hailing from natural origins, provides substantial sweetness, up to 300 times that of sugar, although with a different aftertaste. 

Health and Wellness

In terms of health, both sucralose and stevia are zero-calorie sweeteners, meaning they can both help when it comes to caloric reduction and weight management. Both do not impact blood glucose levels, marking them as helpful alternatives for those managing blood sugar or certain health conditions such as Type 2 Diabetes.

However, stevia stands out for its lack of reported digestive disturbances and its non-disruptive impact on gut microbiota — which is a significant concern with sucralose. 

Heidi Wright, BSN, RN, also notes, “Stevia has also been studied for its glycoside properties, which may help support and maintain healthy blood pressure levels.”

Environmental Impact

In terms of environmental sustainability, stevia takes the lead. Its natural cultivation and extraction processes are a minimal burden on the environment, helping to affirm it as a more eco-friendly choice. Unlike sucralose, stevia is biodegradable and does not vastly contribute to long-term environmental damage. 

The chemical-intensive production of sucralose, alongside its non-biodegradable nature, amplifies its environmental footprint, posing questions about its sustainability in the long run.

Cooking and Baking

In the realm of culinary applications, both sucralose and stevia exhibit heat stability, making them viable for cooking and baking. However, the natural aspect of stevia might appeal to those leaning towards clean and green eating, as it seamlessly blends with various recipes, enhancing sweetness without additional calories or artificial elements.

So, Which Sweetener Is Best?

While each sweetener holds its ground with unique features, stevia’s natural origin, minimal environmental impact, and absence of adverse effects on gut health place it in a more favorable light for some.

The choice between sucralose and stevia does still come down to individual preferences, dietary needs, and environmental considerations — but for those who prioritize natural ingredients, eco-friendliness, and a holistic approach to health, stevia might be the better choice.
