Oral disorders, such as masticatory dysfunction, reportedly influence dietary behavior, nutrient intake, and systemic diseases [1]. Masticatory dysfunction can result in avoidance of foods that are considered difficult to chew and consequently a preference for soft and easily chewable foods [2][3][4]. Older adults with tooth loss, faulty dentures, and/or masticatory dysfunction opt for only soft and easily chewable foods; thus, they could be susceptible to certain diseases and frailty due to a reduced intake of important nutrients, such as dietary fiber, vitamins, and proteins [5]. Tooth loss and lower occlusal force can lead to reduced masticatory stimulation, with a consequent decrease in brain function [6]. Previous animal studies have shown that a reduction in masticatory afferent stimuli affects the synaptic density of the central nervous system, and long-term soft diet consumption could decrease the number of neurons and reduce memory function [7,8]. Several human experimental and epidemiological studies have reported the effects of masticatory ability J Prosthodont Res. 2023; **(**):
