“…The prevalence of swallowing disorders has been estimated to be 16% of the general population in a high-income, urban context (Eslick & Talley 2008) and is therefore expected to be even higher in the Majority World. As feeding can be affected in a myriad of ways when a person presents with a disability (Adams et al 2012;Bilyk et al 2009;Castano & Capdevila 2010;Schwarz 2003), we consider reduced HCP and HAW knowledge and experience of feeding and swallowing disorders to be a risk factor that may contribute to reduced food access and therefore an increased risk of food insecurity for people living with disabilities. In terms of the conceptual framework (Figure 1), reduced HCP and HAW knowledge and experience of disability and feeding issues is likely to affect the quality and sufficiency of food assistance efforts.…”

“…Furthermore, symptoms such as gastroesophageal reflux, dysphagia, prolonged feeding time and increased feeding-related caregiver stress have been identified in the cerebral palsy population (Adams et al 2012;Schwarz 2003). People with visual impairment have been found to have difficulty shopping and preparing food (Muurinen et al 2014) and may consume a diet lacking in variety as a result of inaccessibility of materials and environments (Bilyk et al 2009). Elderly people with physical disabilities limiting mobility may not be able to access shops to buy food and have difficulties preparing food independently (Wylie, Copeman & Kirk 1999).…”

Background: Most people with disabilities the world over can be found in the Majority (or ‘economically developing’) World. This is also where most of the world’s hungry and malnourished are found. We argue that the intersectionality between disability and nutrition may best be understood through a food security framework, and we position all people living with disability, including those experiencing feeding and swallowing disabilities, as at risk for food insecurity, especially those living in humanitarian emergency contexts.Objectives: This study aimed to explore and describe the knowledge and experience of humanitarian aid workers (HAWs) and health care professionals (HCPs) in food assistance contexts with regard to the nutrition and food security of people living with disabilities.Method: In this exploratory, descriptive study, 16 participants with experience in sub-Saharan Africa and Southern Asia participated in an online survey. Three survey participants with extensive experience were also interviewed. Data analysis involved descriptive statistics and thematic content analysis.Results: Results revealed that participants had generally low levels of exposure to and experience with disability, including swallowing and feeding disorders.Conclusions: Reduced knowledge of HAWs and HCPs regarding disability and the lack of professionals such as speech–language therapists, who manage disability-specific issues such as feeding and swallowing disorders, may affect the food security of people living with disabilities in food assistance contexts.

“…Given that retronasal olfaction depends upon the experience of feeding, which, as argued in the next section, is negatively affected by lack of vision (Bilyk et al, 2009), we tested the hypothesis whether retronasal olfactory performance of congenitally blind is worse than that of sighted controls, despite the former having enhanced orthonasal olfactory abilities (Gagnon et al, subm. a).…”

“…Visually impaired subjects encounter various blindness-related obstacles when searching for foods, preparing meals, or eat ing out in restaurants (Bilyk et al, 2009). For example, packaging inherently limits availability of tactile and olfactory information about foods, and de scription of the package contents is rarely provided in Braille.…”

Making Sense of the Chemical Senses

We review our recent behavioural and imaging studies testing the consequences of congenital blind ness on the chemical senses in comparison with the condition of anosmia. We found that congenitally blind (CB) subjects have increased sensitivity for orthonasal odorants and recmit their visually de prived occipital cortex to process orthonasal olfactory stimuli. In sharp contrast, CB perform less well than sighted controls in taste and retronasal olfaction, i.e. when processing chemicals inside the mouth. Interestingly, CB do not recruit their occipital cortex to process taste stimuli. In contrast to these findings in blindness, congenital anosmia is associated with lower taste and trigeminal sensitiv ity, accompanied by weaker activations within the 'flavour network' upon exposure to such stimuli. We conclude that functional adaptations to congenital anosmia or blindness are quite distinct, such that CB can train their exteroceptive chemical senses and recruit normally visual cortical areas to process chemical information from the surrounding environment.

“…Behavioral choices, such as little exercise and excess food consumption, that lead to weight gain are associated with the development of type II diabetes and complications including diabetic retinopathy. Visual impairment can lead to limited access to varied diets and physical activity 2 and thus potentially lead to further exacerbation of diabetes-related complications including diabetic retinopathy. The vicious cycle then continues and the original question of temporality is moot.…”
