2026 Global Wellness Trend: Focus on "Fiber" - A New Gut Health and Beauty Approach Led by Fermented Dietary Fiber

The Fermented Dietary Fiber Promotion Project held the "New Gut Health Frontline: Fermented Dietary Fiber 'Gut x Skin' Trend Presentation" on May 11th, ahead of "Fermented Dietary Fiber Day" on May 18th.

As a global "fiber comeback" progresses and attention to fermented dietary fiber grows in Japan, the event featured presentations on the latest research by Dr. Jun Kunisawa, Deputy Director of the National Institute of Health and Nutrition, National Institutes of Biomedical Innovation, Health and Nutrition, practical case studies in the beauty field by dermatologist Dr. Maiko Yamazaki, and announcements of social implementation initiatives by five participating companies. It served as a platform to communicate the potential of fermented dietary fiber as a new wellness market that integrates research, beauty, and product development.

Kunihiro Nishizawa, Secretary-General of the Fermented Dietary Fiber Promotion Project, introduced the global re-attention to "fiber (dietary fiber)" as a wellness trend for 2026. He explained that, especially in Europe and the US, there is a shift from traditional protein-heavy diets to a fiber-maximizing approach centered on improving the gut environment. In Japan, research on fermented dietary fiber, which is easily fermented in the gut, is also advancing. He stated that the presentation was held with the desire to widely disseminate this knowledge and encourage its incorporation into daily life.

Dr. Kunisawa explained the concept of "postbiotics" as an evolution of gut health. Postbiotics refer to beneficial metabolites produced by gut bacteria, and fermented dietary fiber plays a crucial role in this process. Recent research has revealed that short-chain fatty acids, produced through a "bacterial relay" where multiple bacteria work cooperatively in the gut, have multifaceted functions such as inflammation suppression and immune regulation. Dr. Kunisawa lectured on how fermented dietary fiber will become increasingly important as a foundational component supporting overall health and beauty, starting from the gut environment.

Following this, Dr. Yamazaki's lecture introduced practical examples of skin improvement through inner care. She explained from a clinical perspective that improving the gut environment directly impacts skin condition, not just external care. She clarified that a deteriorated gut environment causes inflammation, leading to increased skin problems such as reduced skin barrier function. She presented multiple research results showing that inflammation was suppressed by the intake of fermented dietary fiber, and recent studies demonstrated clear changes in the skin, such as improved skin barrier function, texture, wrinkles, and pore condition, in a relatively short period of six weeks.

Part 2: Gut Health Implementation Phase - Latest Trends

In Part 2, Secretary-General Nishizawa introduced the initiatives of the Fermented Dietary Fiber Promotion Project and the latest market trends. The project has expanded to 16 participating companies, moving beyond research and product development to a "social implementation phase" including retail distribution and handling at specialty stores, thereby broadening the environment for consumers to regularly consume fermented dietary fiber.

Announcements of Latest Initiatives by Participating Companies

Finally, each participating company introduced their product development and initiatives utilizing fermented dietary fiber. Its use is progressing in diverse categories, expanding consumption opportunities according to daily life scenes. The initiatives of each company are not isolated but create synergistic effects through collaboration with the promotion project and among participating companies. Fermented dietary fiber will continue to develop initiatives aimed at further growth as a new wellness area where research, products, and consumer experience are integrated.
