Abstract
Today, it is known that the elderly population is increasing rapidly with the quality of life. The United Nations estimate that one in six people will be 65 years or older by 2050. This situation causes interest in the old age period to increase day by day. In parallel with this, studies on the aging process have grown rapidly. Especially the health problems accompanying extended life expectancy and its treatment have become the focus of researchers in recent years. It is a known fact that some sensory and physiological changes in old age affect the quality of oral food intake and food taste. This may lead to inadequate nutritional intake and even rejection of food intake in the elderly. Therefore, severe malnutrition and sarcopenia occur in these individuals, and their life span is shortened. In this review, the effects of aging-related oropharyngeal and esophageal changes and problems on oral food intake will be evaluated. Our increasing knowledge on this subject will contribute to healthcare professionals in the prevention and treatment of health problems such as malnutrition that may occur during the aging process. In this review, a literature search was conducted with the keywords “older” or “elderly” or “geriatrics” and “nutrition” or “malnutrition” and “oropharyngeal functions” or “esophageal functions” in PubMed, ScienceDirect, and Google Scholar electronic databases.
Some changes may occur in oropharyngeal and esophageal functions with aging.
Sensory and physiological changes in the aging process affect oral food intake and nutritional status.
Impairments in oral food intake in elderly individuals can lead to malnutrition and sarcopenia.
Age-related changes affecting oral food intake increase the importance of nutritionists with the increase in the elderly population.
