Chewing Gum and Intermittent Fasting May Boost Brain Health in Aging Adults
King's College study tests whether simple chewing and fasting patterns can enhance cognitive function and neurogenesis in older adults.
Summary
Researchers at King's College London investigated whether two simple interventions could combat age-related cognitive decline. The study tested intermittent energy restriction (eating very low calories for 2 days, then normal eating for 5 days) and regular chewing gum use in 123 participants over 3 months. Scientists measured cognitive performance related to hippocampal neurogenesis - the brain's ability to generate new neurons in the memory center. They also tracked levels of Klotho, an anti-aging protein that declines with age. This completed trial represents an innovative approach to brain health, combining accessible dietary patterns with mechanical stimulation through chewing to potentially enhance neural stem cell function and preserve cognitive abilities during aging.
Detailed Summary
A groundbreaking study from King's College London explored whether intermittent fasting and chewing gum could slow cognitive aging by enhancing the brain's ability to generate new neurons. The research focused on adult hippocampal neurogenesis, a process where new brain cells form in the memory center, which typically declines with age.
The randomized controlled trial enrolled 123 participants in a parallel design study lasting 3 months. Participants were assigned to one of four groups: intermittent energy restriction alone, chewing intervention alone, both interventions combined, or a control group. The energy restriction protocol involved eating very low calories for 2 consecutive days followed by 5 days of normal eating. The chewing intervention required participants to chew one piece of gum for 10 minutes, three times daily.
Researchers measured cognitive performance specifically related to neurogenesis-associated functions and tracked circulating levels of Klotho, an anti-aging protein that supports neural health. The study completed in March 2020, providing valuable data on accessible interventions for brain health.
This research addresses a critical need in longevity science by testing simple, implementable strategies that could preserve cognitive function during aging. The combination of metabolic intervention through intermittent fasting and mechanical stimulation through chewing represents an innovative approach to supporting neural stem cell health and potentially maintaining sharper cognitive abilities as we age.
Key Findings
- Intermittent energy restriction involved 2 days very low calories, 5 days normal eating over 3 months
- Chewing gum 10 minutes, 3 times daily was tested as cognitive enhancement intervention
- Study measured hippocampal neurogenesis-related cognitive performance in 123 aging adults
- Researchers tracked Klotho protein levels as biomarker of anti-aging effects
- Trial completed successfully, providing data on accessible brain health interventions
Methodology
This was a randomized controlled parallel design trial with 123 participants over 3 months. The study used four intervention groups including intermittent energy restriction, chewing, combined interventions, and control. Duration allowed assessment of sustained cognitive and biomarker changes.
Study Limitations
The 3-month duration may be insufficient to detect long-term neurogenesis effects. Generalizability depends on participant demographics and baseline health status, which aren't fully detailed in available information.
