“…There are, unfortunately, many clinical conditions where low palatability is a major concern, as indicated in eating disorders (e.g., Reilly, 2018a). For examples, exaggerated taste neophobia undoubtedly plays a role in aspects of avoidant/restrictive food intake disorder (e.g., Dovey, 2018) and has a major influence on the feeding behavior of individuals with special needs, including autism (e.g., Kral, 2018; Williams & Seiverling, 2018). A better understanding of the neural circuits and mechanisms of taste neophobia may provide a platform for the development of treatments and interventions that will benefit these clinical populations.…”

Taste neophobia is a feeding system defense mechanism that limits consumption of an unknown, and therefore potentially dangerous, edible until the post-ingestive consequences are experienced. We found that transient pharmacological inhibition (induced with the GABA agonists baclofen and muscimol) of the gustatory thalamus (GT; Experiment 1), but not medial amygdala (MeA; Experiment 2), during exposure to a novel saccharin solution attenuated taste neophobia. In Experiment 3 we found that inhibition of MeA neurons (induced with the chemogenetic receptor hM4DGi) enhanced the expression of taste neophobia whereas excitation of MeA neurons (with hM3DGq) had no influence of taste neophobia. Overall, these results refine the temporal involvement of the GT in the occurrence of taste neophobia and support the hypothesis that neuronal excitation in the GT is necessary for taste neophobia. Conversely, we show that chemogenetically, but not pharmacologically, inhibiting MeA neurons is sufficient to exaggerate the expression of taste neophobia.

“…As the child gains skills and comfort, the child would progress to a slightly increased texture challenge. This approach to product development as a stepped process is supported by studies describing interventions for selective eating (Williams & Seiverling, 2018). As mentioned earlier in this article with the foods developed for older adults, this approach has been taken with infant foods but primarily with semi-solids (i.e.…”

SummaryIn the development of food products with optimized nutritional and sensory properties, the emphasis is often placed more on the nutrient content of the food rather than the texture of the food. The objective of this short opinion piece is to argue that texture should be considered an integral property of a personalized food based, as illustrated using two case studies. The first case study profiles older adults, a broad group who often experience an unwanted decrease in food texture variety in their diets, with associated negative health outcomes. The second case study examines children with Down syndrome who confront the task of expanding their food texture repertoire to allow for a healthy eating future but face challenges in texture handling due to delays in oral processing development. Following an overview of the texture challenges facing each of these groups, the importance of extending research to partner with food industry to develop food products with desired texture properties and appropriate food structure is presented.
