How much sugar is in liquorice tea?

4 min read

While it tastes remarkably sweet, a standard cup of pure, brewed liquorice tea contains virtually zero grams of sugar. This surprising fact reveals that the sweetness is not from added sucrose, but from a potent natural compound found in the root itself.

Quick Summary

Standard brewed liquorice root tea contains no sugar, deriving its sweet taste from the natural compound glycyrrhizin. The tea is a low-calorie alternative to sugary drinks, though excessive intake is cautioned due to potential health effects from glycyrrhizin. A check of product-specific labels is always recommended.

Key Points

  • Zero Grams of Sugar: Pure liquorice tea contains no added or natural sugars from the root itself.

  • Natural Sweetness: The sweet flavour comes from glycyrrhizin, a compound up to 50 times sweeter than table sugar.

  • Low-Calorie Option: As it is sugar-free, the tea is virtually calorie-free, making it an excellent alternative to sugary drinks.

  • Moderation is Key: Excessive, long-term consumption of glycyrrhizin can raise blood pressure and cause other health issues, so intake should be limited.

  • Read the Label: Always check the ingredients list for blended teas, which may contain other ingredients with added sugars.

  • Health Warnings: Individuals with high blood pressure, certain medical conditions, or who are pregnant should consult a doctor before regular consumption.

The question of how much sugar is in liquorice tea is a common one, especially for those mindful of their sugar intake. The answer is both simple and surprising: pure, brewed liquorice tea contains virtually no sugar. The intensely sweet flavour comes not from added sweeteners but from a potent compound naturally present in the liquorice root, Glycyrrhiza glabra. Understanding this distinction is key to appreciating the tea as a healthy alternative to sugary beverages, while also acknowledging the need for moderation.

What Makes Liquorice Tea So Sweet?

The remarkable sweetness of liquorice tea is attributed to glycyrrhizin, the primary active compound found in liquorice root. Glycyrrhizin is an extremely powerful natural sweetener, estimated to be 30 to 50 times sweeter than table sugar (sucrose). This compound provides the sweet taste without contributing to the sugar content, carbohydrate load, or caloric value in the same way that sucrose does.

Glycyrrhizin: The Natural Sweetener

Unlike sugar, which is a carbohydrate and is metabolized for energy, glycyrrhizin is a triterpenoid glycoside. It stimulates the sweet taste receptors on the tongue, creating the perception of sweetness without the metabolic impact of sugar. This makes liquorice tea an appealing option for those looking to satisfy a sweet craving while adhering to low-sugar or low-carbohydrate diets, such as diabetics or those managing their weight.

The Nutritional Profile: Is Liquorice Tea Sugar-Free?

Nutritional data for pure, brewed liquorice root tea confirms its sugar-free status. Commercial brands often list 0 grams of sugar and 0 calories per serving. However, it is essential to distinguish between pure liquorice root tea and blended teas. Many herbal tea blends incorporate liquorice root for its natural sweetness but may also contain other ingredients that add sugar or calories. Always check the ingredients list and nutritional information to ensure you are consuming a truly sugar-free product.

Blended Teas and Added Ingredients

For instance, a tea brand might combine liquorice root with other herbs like mint, ginger, or aniseed. While these combinations can be delicious, the risk of added sugars increases. Some companies might even add extra flavourings or sweeteners. The safest bet for those strictly avoiding sugar is to opt for a tea that lists only "liquorice root" or "licorice root (Glycyrrhiza glabra)" in its ingredients.

Feature Pure Liquorice Tea (Brewed) Standard Sweet Tea (Sugared)
Sugar Content 0g (Naturally sweetened by glycyrrhizin) Varies (Typically high in sucrose)
Calorie Content 0-2 calories Varies (High, depending on sugar added)
Sweetness Source Glycyrrhizin Added sucrose
Flavour Profile Earthy, bittersweet, and aniseed notes One-dimensional, sweet taste
Health Considerations Benefits with moderate use; precautions for excessive intake Contributes to increased blood sugar, weight gain, and dental problems

Health Considerations and Precautions

While the sugar-free nature of liquorice tea is a major benefit, it is important to be aware of the potential health implications of glycyrrhizin with excessive, prolonged consumption. Glycyrrhizin can affect the body's cortisol levels, which can lead to side effects such as elevated blood pressure, potassium deficiencies (hypokalemia), headaches, and fatigue. The World Health Organization and other expert bodies recommend limiting daily glycyrrhizin intake to around 100 mg. Pregnant women and individuals with pre-existing conditions like hypertension or heart, liver, or kidney disease should consult a healthcare professional before drinking liquorice tea regularly. For those who enjoy liquorice's flavour but wish to avoid glycyrrhizin, some products are made with deglycyrrhizinated liquorice (DGL).

How to Enjoy Liquorice Tea Responsibly

To ensure you reap the benefits of this naturally sweet beverage without the risks, follow these simple guidelines:

  • Read the Label: Always check the ingredients list to confirm you are buying pure liquorice root tea. Look for brands that explicitly state they have "no added sugar" or similar guarantees.
  • Brew at Home: Brewing your own liquorice tea from loose root is the best way to control the content. You can find dried liquorice root at health food stores or online specialty tea shops.
  • Limit Your Intake: As with any herbal remedy, moderation is key. Stick to small, measured servings and avoid consuming it daily for extended periods.
  • Consult a Professional: If you have any medical concerns, especially if you have high blood pressure or are on medication, seek advice from a doctor or dietitian before incorporating liquorice tea into your regular routine.

Conclusion

In summary, pure liquorice tea contains no sugar, making it an excellent, low-calorie alternative for those seeking a naturally sweet beverage. The sweetness comes from glycyrrhizin, a compound far sweeter than table sugar but without the associated negative metabolic effects. However, the same compound requires careful and moderate consumption due to the risk of side effects, such as elevated blood pressure, in high doses or with prolonged use. By choosing pure root varieties and drinking it in moderation, you can enjoy the unique flavour of liquorice tea as part of a healthy, sugar-conscious lifestyle.

Frequently Asked Questions

Yes, pure liquorice tea contains no sugar and can be a safe, sweet-tasting beverage for diabetics in moderation. However, consult a healthcare professional before regular consumption, as high doses of glycyrrhizin can have effects on health.

The sweetness comes from a natural compound called glycyrrhizin, which is present in the liquorice root. Glycyrrhizin stimulates the sweet taste receptors on your tongue, but it is not a sugar and is metabolized differently by the body.

Pure liquorice tea does not cause a blood sugar spike because it contains no sugar. In fact, some studies suggest certain compounds in liquorice root may even have anti-diabetic properties, though the concentration in tea is too low to be medically effective.

Daily consumption should be done with caution. Long-term, excessive intake of liquorice root tea can lead to health issues, particularly elevated blood pressure, due to its glycyrrhizin content. It is best to drink it in moderation.

Excessive intake of glycyrrhizin, the compound responsible for liquorice's sweet taste, can lead to side effects such as elevated blood pressure, low potassium levels (hypokalemia), headaches, and fatigue.

Check the ingredients list and nutritional label on the product packaging. A pure liquorice tea will only list "liquorice root." If other ingredients like fruit concentrates, flavourings, or sugar are listed, the tea likely contains added sugars.

Glycyrrhizin is a natural sweetener, but it is not harmless in large quantities. Its effects on blood pressure and potassium levels mean that its consumption should be monitored, especially by individuals with pre-existing health conditions.
