This scoping review synthesizes 22 studies on high-fat diet effects on salivary glands, identifying patterns of oxidative stress, inflammation, and structural changes across gland physiology. However, the evidence is inconsistent and largely preclinical; the review explicitly acknowledges heterogeneity by gland type, exposure duration, and metabolic status, and calls for further longitudinal and translational work to clarify mechanisms and clinical relevance.
Scoping review. Studies examining effects of high-fat diet on salivary gland physiology, structure, and function.. Intervention: High-fat diet (HFD) exposure.
HFDs affected four major aspects of salivary gland physiology: reduced antioxidant and digestive enzyme activity, altered salivary proteins (mucin and IgA), increased inflammatory biomarkers and oxidative stress, and morphological/functional changes (reduced secretion, fibrosis, vacuolization, inflammatory infiltration, lipid accumulation) Some studies reported no significant changes in salivary gland function or structure in response to HFD Response variability observed according to gland type, HFD exposure duration, and metabolic status
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
Clinicians should recognize that HFD consumption may impair salivary gland function through oxidative stress and inflammation, but current evidence is fragmented and inconsistent. Clinical applicability remains unclear pending longitudinal and translational studies in human populations.
A scoping review mapping fragmented literature on HFD effects on salivary glands; identifies biological mechanisms but acknowledges inconsistency and heterogeneity, with no quantified effect sizes or clinical outcomes reported.

Introduction: Obesity is a growing global health concern, largely driven by high-fat diet (HFD) consumption, which promotes adipose tissue accumulation and increases metabolic disorder risk. Beyond systemic effects, obesity may impair salivary gland function, which is essential for maintaining oral homeostasis. However, evidence regarding the effects of HFDs on salivary glands remains fragmented and inconsistent. This scoping review aimed to map the literature on HFD-induced salivary gland alterations and elucidate the underlying biological mechanisms. Review: The review followed PRISMA-ScR guidelines. Relevant studies were identified through comprehensive searches of PubMed and Scopus and screened using predefined eligibility criteria. Twenty-two studies were included. HFDs affected four major aspects of salivary gland physiology: reduced antioxidant and digestive enzyme activity; altered salivary proteins, including mucin and IgA; increased inflammatory biomarkers and oxidative stress; and morphological and functional changes, including reduced salivary secretion, fibrosis, vacuolization, inflammatory infiltration, and lipid accumulation. However, some studies reported no significant changes, suggesting that responses may vary according to gland type, HFD exposure duration, and metabolic status. Conclusion: HFD consumption induces oxidative stress, inflammation, and structural and molecular alterations in salivary glands, potentially contributing to salivary dysfunction. Further longitudinal and translational studies are needed to clarify the underlying mechanisms and clinical implications.
