Back to the Chicory Roots: Dietary Fibers Rediscovered to Benefit Human Health

Summary

Despite having plenty of food to choose from, rates of diabetes and obesity are still rising. One big reason? We are not getting enough dietary fibers. This thesis examined how dietary fibers, especially those from dried chicory root, might help reverse this trend.

In the past, we viewed fibers as part of the plant's intricate structure. However, present industrial food production processes often include fibers separated from their plant sources, missing the bigger picture. The thesis argues that eating fibers in their natural, minimally processed form—as whole foods (edible plants)—is more beneficial for our health.

Chicory roots are a prime example. Rich in inulin, they are exceptionally high in dietary fibers when dried. Our gut bacteria break down these fibers, enhancing their health benefits. Through various studies, including human trials, we showed that dried chicory root can boost gut bacteria and increase the production of butyrate—a compound that supports both gut and metabolic health. This means dried chicory root not only aids digestion but also helps regulate blood sugar and fat tissue. The takeaway? To tackle modern health issues, we should prioritize whole, fiber-rich foods over processed ones.
