Food Variety Score and Geriatric Nutritional Risk Index Mediate the Relationship Between Masticatory Function and Osteoporosis

This study confirms that better masticatory function, measured by FTUs, is significantly associated with a lower risk of osteoporosis, a link partially explained by improved food variety (FVS) and nutritional status (GNRI). Maintaining adequate masticatory function may therefore be related to a reduced incidence of osteoporosis, possibly through its supportive role in nutritional health. This study highlights the potential of oral health preservation in preventing osteoporosis. Further prospective studies are needed to confirm the causal relationship and optimize clinical intervention.
