Stevia: The Natural Alternative to Sugar and Artificial Sweeteners

Stévia : L’Alternative Naturelle au Sucre et aux Édulcorants Artificiels

Stevia, a name that is increasingly resonating in the health and nutrition field, is much more than just a sweetener. Derived from the Stevia rebaudiana plant, this natural alternative to sugar is recognized for its multiple benefits, both for health and for taste pleasure.

Origin and history of stevia

Stevia, scientifically known as Stevia rebaudiana , has a rich and fascinating history that has its roots in South America . Used for centuries by indigenous peoples, it is now recognized worldwide as a natural sweetener with multiple virtues.

  • Step 1: Origins in South America
    "The first uses of stevia date back several centuries. The Guarani, an indigenous people of Paraguay, used the leaves of Stevia rebaudiana as a natural sweetener in their drinks and for its medicinal properties."

  • Step 2: Scientific discovery
    "In 1899, Swiss botanist Moïse Santiago Bertoni was the first to scientifically describe stevia after discovering the plant in Paraguay. He was amazed by its exceptional sweetening power."

  • Step 3: First industrial uses
    "During the 20th century, Japan was the first country to use stevia on a large scale.

    1. Low Glycemic Index: A Revolution for Blood Sugar

    • Explanation :
      Stevia has a glycemic index of zero , meaning it has no impact on blood sugar. Unlike traditional sugar, it does not cause blood glucose spikes, making it an ideal solution for:
      • People with diabetes.
      • Those seeking to prevent metabolic disorders such as insulin resistance.

    and in the food industry, incorporating it as a substitute for sugar in various products since the 1970s."

  • Step 4: Global Recognition
    "Since the 2000s, stevia has been adopted globally, especially after its approval as a natural sweetener in many countries, including the United States and Europe."

Chemical Composition of Stevia

Stevia, famous for its high sweetening power and natural benefits, owes its unique properties to a combination of specific chemical components . These, grouped under the term steviol glycosides , are responsible for its sweet taste, without the caloric intake. Let’s explore these key molecules in detail.

Steviol glycosides are natural molecules found in the leaves of Stevia rebaudiana . These compounds have a sweetening power that can reach 200 to 300 times that of ordinary sugar , while having a negligible impact on blood sugar.

Focus on the main glycosides:

  1. Stevioside

    • Structure and role:
      Stevioside is one of the most abundant glycosides in stevia leaves. Its complex chemical structure is composed of a steviol skeleton to which sugar groups are attached.

      • Characteristics: Pronounced sweetness with a slight bitter aftertaste.
      • Applications: Used in low cost sweeteners or blends requiring natural sweetness.

      Example: In a sweetened drink, stevioside can completely replace sugar while providing a satisfying taste.

  2. Rebaudioside A (Reb-A)

    • Structure and role:
      Rebaudioside A, often abbreviated as Reb-A, is one of the most sought after glycosides due to its intense sweetness and almost complete lack of bitterness .

      • Characteristics: Sweetening power superior to stevioside, with a sweeter and more pleasant flavor.
      • Applications: Preferred for premium products such as tabletop sweeteners or dessert mixes.

      Example: Natural stevia sweetener sachets typically contain a high concentration of Rebaudioside A for an optimal taste experience.

  3. Other important glycosides:

    • Rebaudioside C and D : Less present than Reb-A but used to balance sweetening mixtures.
    • Dulcoside A : Present in small amounts, contributing to the complexity of the plant's sweetness profile.

Health Benefits of Stevia: Unique Properties

1. Low Glycemic Index: A Revolution for Blood Sugar

Stevia has a glycemic index of zero , meaning it has no impact on blood sugar. Unlike traditional sugar, it does not cause blood glucose spikes, making it an ideal solution for:

  • People with diabetes.
  • Those seeking to prevent metabolic disorders such as insulin resistance.

Example: Replacing sugar with stevia in a coffee or pastry allows you to enjoy the sweetness without fear of a glycemic imbalance.

2. Hypoglycemic Properties: A Support for Diabetics

Active compounds in stevia, such as steviol glycosides , promote better regulation of blood glucose. Studies have shown that these molecules can help stimulate insulin production and stabilize blood sugar levels after a meal.

Example: Incorporating stevia into a balanced diet can reduce the risk of diabetes-related complications.

3. Rich in Antioxidants: A Shield Against Oxidative Stress

Stevia leaves contain natural antioxidants , which help fight free radicals responsible for premature aging and many chronic diseases (cancers, cardiovascular diseases, etc.).

Additional benefits:

  • Reduction of inflammation in the body.
  • Strengthening immune defenses.

Example: By incorporating stevia into a drink or dessert, we benefit not only from its sweetness but also from its anti-aging and protective benefits.

Health Benefits of Stevia

Stevia is more than just a natural sweetener: it offers a unique combination of health benefits, thanks to its hypoglycemic properties , low glycemic index , and richness in antioxidants . Let’s explore these major benefits in detail.


1. Low Glycemic Index: A Revolution for Blood Sugar

  • Explanation :
    Stevia has a glycemic index of zero , meaning it has no impact on blood sugar. Unlike traditional sugar, it does not cause blood glucose spikes, making it an ideal solution for:

4. Compatible with Specific Diets

Stevia is perfectly suited to:

  • Sugar-free diets (diabetic or ketogenic).
  • Weight loss programs due to its absence of calories.

Example: Stevia-based sweeteners help maintain a reduced calorie intake without sacrificing taste.

Stevia Side Effects and Precautions

Although stevia is widely recognized as a safe and beneficial natural sweetener, it is essential to understand its possible side effects and precautions for optimal use.

1. Respect the Acceptable Daily Intake ( ADI)

The ADI for steviol glycosides is set at 4 mg per kilogram of body weight per day by health authorities, such as EFSA (European Food Safety Authority).

  • For a person weighing 70 kg, this is equivalent to 280 mg of steviol glycosides.
  • Excessive consumption could lead to digestive imbalances or other discomforts.

2. Possible Drug Interactions

Stevia may interact with certain medications, especially those that affect:

  • Blood pressure : Since stevia has a slight hypotensive effect, it can amplify the effect of antihypertensive drugs.
  • Blood sugar levels : Diabetics on medication should monitor their blood sugar levels, as stevia may enhance the action of hypoglycemic medications.
  • Caution: Consult a healthcare professional if you are taking medication for high blood pressure or diabetes before consuming products containing stevia.

3. Laxative Effects at High Dose

Excessive consumption of stevia, especially in the form of processed products containing excipients such as polyols (sorbitol or erythritol), can cause:

  • Bloating.
  • Diarrhea or digestive discomfort.

Comparison between Stevia and other Sweeteners

Choosing the right sweetener can be tricky. To help clarify the differences, here's a detailed comparison between stevia , aspartame , and sucralose , based on key criteria such as their sweetening power , health impact , and culinary applications.
