Blanched, matured leaves are often mixed with other greens and consumed as a vegetable, while the ground root is consumed as a coffee substitute.

The Benefits of Chicory Root

From improving digestion to supporting heart health, the benefits of chicory root detailed below are backed by sound evidence.

Digestive Health

One of the most recognized uses of chicory relates to digestive health thanks to its natural supply of inulin. Recognized as a starchy dietary fiber source, inulin is not digested or absorbed in the stomach. Instead, inulin acts as prebiotic source, in which it travels to the colon. Probiotics, or healthy gut bacteria, then use it to grow, in turn improving bowel function and general health.

According to a study published in the Journal of Clinical Gastroenterology, a daily dose of inulin may improve gut function by promoting bifidobacteria growth, a well-known probiotic. What’s more, it was well tolerated by subjects with gastrointestinal complaints.

And while there was debater on whether or not inulin could be counted as a nutritional fiber source, the FDA recently deemed it countable on Nutrition Facts and Supplement Facts labels.

Heart Health

Fiber’s role in heart health has been long explored, as adequate intake of the non-digestible starch shows to reduce the risk of cardiovascular disease by reducing LDL (or bad) cholesterol levels. Dietary fiber may also reduce inflammatory c-reactive protein levels and high blood pressure, two biomarkers for heart disease.

Though the research specific to inulin’s role in heart health, a newly published study in Nutrients discovered inulin improves high triglyceride levels following a meal in mice.

Bone Health

The milk added to chicory coffee might not be the only contributor to bone health… The inulin sourced by chicory shows to increase calcium absorption in the intestinal tract, thus increasing bone mineral density and calcium retention through enhanced calcium absorption. An animal study published in the Journal of Nutrition suggests chicory inulin not only increases calcium absorption, but also increases mineral parameters in whole-body bones.

Skin Health

Chicory benefits for skin primarily stems from topical use. For centuries, a paste of chicory leaves has been applied directly to the skin for swelling and inflammation. And explaining the current trends and future perspectives of prebiotics research, prebiotics are expected to enter the dermatological sector and boost skin health.

Weight Management

Higher intakes of dietary fiber are linked to lower body weights. The impact of fiber on weight mostly relates to its ability to control appetite, thus prevent overeating. Compared to low-fiber foods, plant-based sources rich in fiber tend to be more filling without supplying large amounts of calories.

Type 2 Diabetes

Losing weight and maintaining a healthy body weight weight lowers the risk of type 2 diabetes. There is also evidence suggesting chicory inulin as a nutritional supplement may be beneficial for the patients with type 2 diabetes.

Also in a study published in Journal of Traditional and Complementary Medicine, researchers divided participants into a test group that drank either chicory root extract or non-chicory root extract. Those who drank the chicory root extract displayed decreased hemoglobin A1c levels, a blood test that measures average blood sugars for up to three months, leading researchers to suggest that chicory root extract could delay or prevent the early onset of diabetes.
