Purpose of Review

The human gastrointestinal tract (stomach, intestine, and pancreas) secretes more than 20 different hormones. These hormones influence many physiological processes and may contribute to the risk of developing several chronic diseases. Consequently, a better understanding of the factors that influence their secretion and action may lead to a new approach in preventing or treating chronic disease. Several factors are known to influence the gut hormone response including the macronutrient content or the physical characteristics of the ingested meal. However, despite having a major role in the digestion of foods, the influence of mastication on the gut hormones has gained little attention. This brief review will discuss the limited number of studies that have been conducted and make suggestions for further research in this area.

Recent Findings

At this time, limited research has been conducted to determine the influence of mastication on the gut hormone response. While emerging evidence suggests that mastication may contribute to the gut hormone response, the current studies do not isolate the effect of mastication from other factors such as differences in the particle size of the swallowed bolus. Consequently, they do not unambiguously indicate that mastication directly influences the gut hormone response. There are several theoretical reasons why mastication would influence the gut hormone response and further research is required.


If there is an influence of mastication on the gut hormone response, then inter-individual differences in mastication may contribute to the risk of some chronic diseases. Moreover, the impact of impaired mastication, due to tooth loss or aging, on the gut hormone response requires elucidation as these groups may be at increased risk of chronic disease or poor body weight due to changes in the satiation or satiety response.

Br J Nutr. 2013;110(2):384–90. While this paper suggests that increasing masticatory activity can reduce appetite, possibly due to a change in the gut hormone response, it also found that increasing masticatory activity increased the post-prandial insulin response. Consequently, it should be recognized that altering masticatory activity to influence the gut hormone response may have portentially deleterious effects. CrossRefPubMedGoogle Scholar
