What Is Licorice?

Is Red Licorice Bad for You

Licorice is a versatile herb with a long history of use around the world for both culinary and medicinal purposes. The sweet root of the licorice plant, Glycyrrhiza glabra, has origins in southern Europe and parts of Asia. This flavorful root has found its way into a variety of market forms, such as candies, teas, and extracts.

When it comes to licorice, you may come across two main types: black licorice and red licorice. Black licorice is made from the extract of Glycyrrhiza glabra root, which gives it a unique and distinct flavor. This natural licorice has been used for centuries to treat conditions like peptic ulcers and coughs.

In contrast, red licorice usually contains little to no actual licorice extract. It is a candy that has been flavored with anise, which has a taste similar to licorice, but originates from the completely different plant Pimpinella anisum.

Licorice can be cooked and consumed in various forms. Most commonly, it’s found as a key ingredient in licorice candy, such as twists or coated bites. Additionally, the root can be boiled to make tea or used in powdered form to flavor food. Some recipes use licorice as a natural sweetener, while others incorporate it to add depth to a dish.

The plant’s sweet flavor comes from a compound called glycyrrhizin, which is up to 50 times sweeter than sugar. However, it’s essential to remember that consuming large quantities of licorice, especially black licorice, may lead to side effects and should be consumed in moderation.


Red licorice, despite its name, doesn’t actually contain licorice root (Glycyrrhiza glabra) like traditional black licorice does. The term “licorice” in red licorice refers more to the shape and texture of the candy rather than the inclusion of the actual licorice root extract. Red licorice is usually made with a combination of sugar, corn syrup, flavorings, and colorants to achieve its distinctive taste and appearance. 

 Let’s take a closer look at these ingredients commonly found in red licorice:

  • Sugar: Sugar is a primary ingredient in red licorice, contributing to its sweet taste. While sugar is a source of empty calories and excessive consumption can lead to weight gain, it doesn’t inherently pose unique health risks specific to red licorice.
  • Corn Syrup: Corn syrup is a sweetener derived from cornstarch. It adds sweetness and helps maintain the soft and chewy texture of red licorice. Like sugar, excessive consumption of corn syrup can contribute to weight gain and may have negative effects on health when consumed in large quantities.
  • Flavorings: Red licorice is often flavored with artificial or natural flavorings to give it a distinct taste. These flavorings can vary but commonly include fruity or berry flavors. While the specific components of these flavorings may vary among brands, they are generally considered safe for consumption.
  • Colorants: Red licorice gets its vibrant hue from food colorants, typically artificial dyes like Red 40 or Allura Red AC. These dyes are used to enhance the visual appeal of the candy. Concerns have been raised about potential health risks associated with artificial food colorants, including allergies and hyperactivity in some individuals. However, regulatory agencies such as the FDA have approved their use as safe in moderate quantities.

It’s important to note that the specific ingredients and their proportions can vary among different brands and types of red licorice. Reading the product label and being aware of any personal dietary restrictions or sensitivities is recommended before indulging in this candy. Moderation and a balanced overall diet are key to enjoying red licorice without significant health concerns.

Nutrition Information

Red licorice’s primary ingredient is sugar, providing sweetness and calories that contribute to its flavor. A typical serving of red licorice (around 40 grams) contains approximately 140 calories, with most of them coming from carbohydrates. Keep in mind that consuming excessive sugar can lead to weight gain and other health issues.

In addition to sugar, red licorice contains some protein and sodium. Protein gives a little bit of structure to the candy, and sodium acts as a preservative. However, these quantities are usually minimal and don’t contribute much to the nutritional profile.

As for vitamins and minerals, red licorice is not a significant source. While you may find trace amounts of some vitamins and minerals, they are not present in high enough quantities to make a considerable impact on your overall dietary needs.

Another aspect of red licorice to consider is the flavoring ingredients. Traditional licorice flavor comes from licorice extract, which contains glycyrrhizin, a compound with a sweet taste. Glycyrrhizin is responsible for the distinct flavor of licorice, but excessive consumption of glycyrrhizin can lead to health problems such as elevated blood pressure and electrolyte imbalances. To avoid these risks, consume red licorice in moderation.

It is important to note that some red licorice candies do not contain licorice extract or glycyrrhizic acid. Instead, they may use other flavorings, such as artificial fruit flavors, to give the red licorice its distinct taste. In these cases, glycyrrhizin-related health risks wouldn’t apply.

In summary, red licorice contains sugar, minimal protein and sodium, and trace amounts of vitamins and minerals. Traditional licorice flavoring, glycyrrhizin, poses health risks when consumed in excessive amounts. Make sure to enjoy red licorice in moderation to minimize potential health concerns.

Health Benefits of Licorice

Licorice has been known to possess various health benefits due to its bioactive compounds. The licorice plant, also used in candies such as Red Vines, contains glycyrrhiza, which is known to exhibit antioxidant and anti-inflammatory properties. It may help alleviate certain conditions such as pain, swelling, and eczema.

As a natural remedy, licorice can be effective in addressing respiratory issues. For instance, it can provide relief for sore throats, coughs, and asthma due to its soothing effect on the respiratory system. Additionally, it has been reported to be beneficial in treating mouth sores and promoting healthy skin.

Deglycyrrhizinated licorice (DGL) is a modified form of licorice commonly used to treat heartburn and gastroesophageal reflux disease (GERD). By reducing inflammation and soothing the lining of the esophagus, this specialized form of licorice may help to alleviate the discomfort associated with these conditions.

Keep in mind that, while licorice can offer certain health benefits, excessive consumption could lead to side effects such as increased blood pressure and imbalances in cortisol levels. Therefore, it is essential to consume licorice in moderate amounts and seek professional advice if you have any underlying health conditions.

Pros and Cons

When it comes to licorice, there are both benefits and drawbacks that you should be aware of. This is especially true for red licorice, a popular candy that contains some of the same components as natural licorice root.


  • Health benefits: Licorice root has been used in traditional medicine for its potential health benefits, such as its anti-inflammatory and digestive properties. The active compound, glycyrrhizin, found in licorice root.


  • High blood pressure: The main concern with consuming excessive amounts of licorice is the risk of developing high blood pressure. Glycyrrhizin may cause sodium retention and potassium loss in the body, which can lead to increased blood pressure..
  • Weight gain and obesity: Consuming large amounts of red licorice candy can contribute to weight gain and obesity due to its sugar content.

While red licorice may not directly possess all the benefits (and risks) of natural licorice root, it’s worth considering these factors when indulging in this sweet treat. Keep in mind that moderation is key, and it’s essential to consult with a healthcare professional if you have any concerns regarding licorice consumption.

Related Studies

A study found that while red licorice is not necessarily bad for you, it contains high amounts of sugar. This can lead to an increase in calorie intake and present potential health problems if consumed in excess. Moderation is key when it comes to enjoying red licorice.

It is important to note that red licorice often contains artificial colors and flavors. Some individuals might experience allergic reactions or sensitivities to these ingredients. If you find that you are sensitive to these additives, you may want to opt for naturally flavored and colored licorice varieties.

When it comes to dental health, the sticky and sugary nature of red licorice can contribute to tooth decay if proper dental hygiene is not practiced. After enjoying a serving of red licorice, you should brush and floss your teeth to remove any remaining residue.

Lastly, while red licorice is a popular snack, some varieties contain a compound called glycyrrhizin, which is derived from the licorice root. High amounts of glycyrrhizin can cause low potassium levels, high blood pressure, and other health issues. It is essential to limit your intake of licorice-containing products and inform your healthcare provider if you experience any adverse reactions.

What Do Health Experts Say About Licorice

Red licorice is a popular treat enjoyed by many, but experts offer some insights and considerations when it comes to its consumption. Moderation is a key point emphasized by experts, as excessive intake of red licorice can have negative health implications.

The candy’s high sugar content raises concerns, as it can contribute to weight gain, increase the risk of chronic diseases, and negatively impact dental health. Experts advise limiting consumption and focusing on a balanced diet that includes nutrient-dense foods.

In terms of nutrition, red licorice offers little to no nutritional value. It consists primarily of empty calories, lacking essential vitamins, minerals, and fiber. Experts recommend prioritizing a diverse range of fruits, vegetables, whole grains, lean proteins, and healthy fats to meet the body’s nutritional needs. While red licorice can be enjoyed occasionally, it should not replace more nutrient-rich foods in the diet.

Another aspect to consider is the impact on dental health. Red licorice’s high sugar content increases the risk of tooth decay and cavities. Experts stress the importance of maintaining good oral hygiene practices, such as regular brushing and flossing, and reducing the frequency and duration of consuming sugary snacks like red licorice. Opting for healthier snack alternatives or chewing sugar-free gum can help mitigate the negative effects on dental health.

Individual health conditions and dietary needs should also be taken into account when evaluating the suitability of red licorice. Some individuals may have specific dietary restrictions, allergies, or sensitivities that make red licorice unsuitable for consumption.

Seeking guidance from healthcare professionals or registered dietitians is recommended to determine the best dietary approach based on individual circumstances. They can provide personalized advice and suggest suitable alternatives that align with specific health goals.

Who Should Avoid Red Licorice?

While red licorice is generally considered safe for consumption in moderation, there are certain groups of people who may want to exercise caution or avoid it altogether. Here are some individuals who should consider avoiding red licorice:

  • Individuals with diabetes or blood sugar issues: Red licorice is high in sugar and can cause a rapid rise in blood sugar levels. People with diabetes or those who need to manage their blood sugar should be mindful of their sugar intake and may need to avoid or limit red licorice to prevent spikes in blood sugar.
  • Those with dental issues: Red licorice’s high sugar content can contribute to tooth decay and dental problems. Individuals with existing dental issues, such as cavities or sensitive teeth, may want to avoid red licorice or consume it sparingly to minimize the risk of further dental damage.
  • People with allergies or sensitivities: Red licorice often contains common allergens such as wheat, soy, or artificial food colorants. Individuals with known allergies or sensitivities to these ingredients should carefully read the labels or choose alternative treats that better suit their dietary needs.
  • Those on restricted diets: Red licorice may not align with certain dietary restrictions or preferences. For example, individuals following a gluten-free, vegan, or specific allergen-free diet should check the ingredients carefully to ensure the red licorice is suitable for their dietary needs.
  • Individuals watching their weight or on a low-calorie diet: Red licorice is calorie-dense and provides little nutritional value. Those who are trying to manage their weight or adhere to a low-calorie diet may want to limit or avoid red licorice to prevent excessive calorie intake.

Natural Alternatives

If you’re concerned about the potential negative effects of red licorice, such as those found in popular brands like Twizzlers or Red Vines, there are natural alternatives you can consider. Artificial flavors are commonly used in these products, which may lead to headaches or other mild side effects in some individuals.

One option is to look for licorice made with more natural ingredients, such as those that use real licorice extract or flavored with organic fruit juices. You can find such products in specialty stores, or even online, where a variety of brands offer healthier alternatives to mainstream licorice.

Another possibility is to prepare homemade licorice. By doing so, you have complete control over the ingredients and can choose organic or higher-quality components to suit your preferences. Many recipes are available online, catering to various dietary restrictions and personal tastes.

In the U.S, people are increasingly leaning towards healthier snack choices, and numerous companies are catering to this demand by producing licorice alternatives made from natural ingredients. When choosing such products, always make sure to read the labels to ensure they meet your personal dietary needs and standards.


Based on available research, it can be said that consuming red licorice in moderation is generally safe for most people. However, it’s important to note that red licorice is often high in sugar and artificial additives, which can contribute to dental problems and an unhealthy diet if consumed in excess.

You should always be mindful of the ingredients in the red licorice products you purchase, and opt for brands that use natural flavors and colors when possible. Additionally, remember to enjoy red licorice as a treat rather than a staple in your diet.

In conclusion, while red licorice itself may not be harmful to your health, it’s essential to consider the overall context of your diet and lifestyle. Moderation and mindfulness in consumption will ensure that you can enjoy this tasty treat without compromising your health.
