Oral Health and Dietary Intake in Older Adults

Abstract

Purpose of Review

Previous studies have reported that dietary intake is related to systemic diseases and functions. The oral cavity is the first passage through which food passes for consumption, and decline of oral health is considered to be associated with a lower intake of some foods or nutrients. We focused on the relationship between oral health and dietary intake in older adults.

Recent Findings

Most studies have reported oral health, such as number of teeth, tooth loss, occlusal contacts, masticatory ability, denture use, occlusal force, dysphagia, and hyposalivation are associated with intake of some foods and nutrients adjusting for socioeconomic factors.

Summary

Healthy oral function can lead to enough intake of key nutrients. It is also necessary to clarify the association between oral health and malnutrition, such as weight loss or underweight, and the pathways from oral health to several systemic diseases.
