What is chicory?

Chicory is a plant from the Asteraceae family, just like stevia or yarrow. The Cichorium genus includes many wild or cultivated varieties, consumed either for their leaves or their roots.

The Cichorium intybus or “wild chicory” is the most well-known of all. Its roots are harvested, roasted, and then ground into a powder to make the famous hot beverage.

It grows naturally in Europe, India, and North Africa. Often considered a weed, it quickly spreads in meadows, wastelands, and roadsides. The plant has a taproot, yellow-brown in color, and can reach up to 75 cm in length.

While chicory leaves are also edible, its roots are primarily used in herbal medicine. In traditional medicine, they are used to relieve various ailments: wound treatment, diabetes, inflammation…

From the 1980s onwards, research has multiplied. They have highlighted its exceptional composition and numerous benefits for the body. Thus, it improves gastrointestinal comfort and has antioxidant and anti-inflammatory effects. It also alleviates diabetes and protects the heart.

Today, it is mainly cultivated for its roots, used in the production of a coffee substitute. However, the inulin it contains is also used as a sweetening agent and as a texturing agent in the food industry. Thanks to its sweet flavor, it could replace sweeteners and reduce sugar content in industrial foods.

The benefits of chicory


♻️ Improves gastrointestinal comfort

With about 3 g per 100 g, chicory is an interesting source of fiber. It notably contains soluble fibers, including inulin. Also present in artichokes and dandelions, this particular fiber improves gastrointestinal comfort.

Inulin has a prebiotic effect meaning it feeds the good bacteria in the microbiota, allowing them to fully perform their role and develop in good conditions. Thus, it is among the best prebiotic foods, alongside carob or chia seeds. It is recommended in cases of sluggish transit, difficult digestion, bloating, and constipation.

This study from Hokkaido Information University (Japan), conducted on humans, shows how chicory improves intestinal transit.


🔥 Anti-inflammatory

Thanks to its anti-inflammatory effects, chicory is useful for relieving muscle and joint pain related to osteoarthritis and arthritis. It also helps speed up wound healing and relieve certain skin problems like acne and eczema.

Moreover, it contains intybin, a bitter substance with sedative and analgesic properties. It soothes and reduces the sensation of pain.

This study from the University of Texas Southwestern Medical Center (USA), conducted on patients with osteoarthritis, demonstrates the anti-inflammatory potential of chicory.


🥝 Antioxidant

Chicory root contains many antioxidant actives: flavonoids, coumarins, polyphenols… These compounds effectively fight against free radicals and protect the body from their damage. They trap reactive free radicals, stimulate the immune system, and boost the activity of antioxidant enzymes.

Its antioxidants also have hepatoprotective effects and reduce liver lesions.

This study from the University of Damanhour (Egypt), conducted on rats, shows the antioxidant activity of chicory.


🍭 Improves Diabetes

Regular consumption of chicory helps improve diabetes. In addition to reducing blood glucose levels, it lowers blood pressure, which is often very high in diabetics.

Its soluble fibers, including inulin, limit blood sugar spikes after meals, slow down carbohydrate absorption, and improve insulin resistance.

This study from the University of Medical Sciences of Tabriz (Iran), conducted on diabetic patients, shows the effectiveness of chicory in improving the condition.


❤️ Protects the Heart

Chicory is a great protector of the heart and supports its proper functioning. The caffeic acid it contains inhibits platelet aggregation, responsible for thrombi (blood clots).

Moreover, by reducing systolic and diastolic blood pressure, this plant prevents many cardiovascular diseases. Finally, it decreases blood and plasma viscosity for better circulation in the arteries.

This study from the University of Pécs (Hungary), conducted on humans, shows the cardioprotective effects of chicory.

How to Consume Chicory?

Soluble Chicory

Harvested in autumn, the chicory roots are then washed, cut, and dried. They are cut into “chips” and undergo roasting, which gives them a caramelized flavor. Finally, they are ground into grains and sprayed into a drying tower to obtain a fine powder.

Mixed with water, animal or plant-based milk, the soluble form makes it possible to enjoy a delicious hot drink that advantageously replaces coffee. It is prepared the same way and can be enjoyed at any time of the day, even in the evening.

Dried Chicory Roots

It is also possible to find dried chicory roots. This form is interesting for preparing a decoction to relieve gastrointestinal disorders. To do this, simply boil 50 g of roots in 50 cl of water and let it infuse for about 10 minutes. Strain and then enjoy.

Consume Sustainably: Choose Local, Organic, and Fair-Trade Chicory

✓ Chicory is cultivated in many countries worldwide (South Africa, United States, Australia, India…) and in Europe (Belgium, Netherlands, Germany…). France is simply the leading European producer. With 50,000 tons harvested each year, the Nord-Pas-de-Calais region accounts for 95% of French production!

✓ Therefore, chicory grown in France can be easily found. Favor those grown through organic agriculture and/or fair-trade channels.

Dosage

The recommended dosage is 3 to 5 g of chicory per day.
