Chewing Activity
How Chewing Influences Our Metabolic Health Monitoring
​
Chewing is the first and critical step in digestion, with a direct impact on glucose regulation, satiety signaling, and nutrient absorption. Despite being often overlooked, chewing efficiency—defined by duration, frequency, and intensity—affects how food is processed and how quickly glucose enters the bloodstream.
Efficient mastication improves:
-
Glycemic control, by modulating the rate of carbohydrate breakdown and absorption.
-
Hormonal responses, such as GLP-1 and PYY secretion, which regulate hunger and digestion.
-
Overall metabolic efficiency, by ensuring optimal mixing with saliva and enzymatic processing before the food reaches the stomach.
Emerging research suggests that modifying chewing behavior could serve as a non-pharmacological strategy to manage post-meal glucose spikes and support metabolic health, especially in conditions like diabetes.
The Importance of Chewing:
Two Scientific Studies
Understanding Chewing Patterns with Electromyography: A New Approach
We introduced an innovative approach to assessing chewing behavior. Unlike previous methods relying on acoustic sensors or piezoelectric devices, our study employs electromyography (EMG) to analyze the activity of the masseter muscles during chewing. This non-invasive technique provides quantitative, real-time data on chewing performance.​
Key Findings from Our Research
Our analysis revealed significant differences in chewing behavior between these two groups.
Non-smokers exhibited a higher number of chews per bite and greater chewing effort, while smokers tended to chew less and exert less force, indicating an inefficient chewing pattern.​​​​​​​​​​​​
Potential Clinical Applications
This research suggests that analyzing chewing patterns could help identify risk factors for metabolic disorders, optimize dietary recommendations, and even assist in dental or speech therapy treatments.
Our study confirmed that chewing efficiency is not just about time—it is influenced by the mechanical work exerted by the muscles.​​​​​​
The Role of Chewing in Glucose Homeostasis
Chewing is often overlooked in discussions about nutrition and metabolism, yet it plays a crucial role in regulating blood sugar levels. Our latest study explores how different chewing patterns affect glycemic response.

Why is Chewing Important for Blood Sugar Regulation?
The act of mastication is not just about breaking down food—it actively influences glucose metabolism. Proper chewing impacts insulin release, gut hormone secretion, and the speed at which glucose enters the bloodstream. In our study, we used electromyographic (EMG) sensors to analyze chewing patterns and correlated them with real-time continuous glucose monitoring.​​​
​​​​Key Findings from Our Research
Chewing Time Matters:
Longer chewing durations were associated with a broader glycemic curve and a faster glucose peak. This suggests that more extended mastication could enhance glucose absorption.
Chewing Power vs. Frequency:
Greater chewing power increased the glycemic response, while a higher number of chews resulted in a smaller glycemic curve. This indicates that chewing efficiency, rather than just frequency, plays a role in glucose metabolism.
Implications for Diabetes Management:
Optimizing chewing habits may be an accessible strategy to modulate blood sugar levels, offering a complementary approach for individuals with metabolic conditions such as diabetes.​
Future Perspectives
Our findings highlight the potential of wearable technology in metabolic health. By integrating chewing analysis with glycemic monitoring, future digital health tools could provide personalized dietary recommendations and real-time feedback to improve metabolic outcomes.
