“…Other potential factors that could mediate effects of food neophobia on diet and weight include chemosensory exploration and perceptions (41) . Food neophobics have been found to rate odours as less pleasant, sniff odour samples less vigorously (42) and identify fewer odours correctly (28) than food neophilics. Limitations of the present study include the large proportion of self-reported data and the cross-sectional design of analyses.…”

“…No standardized or widely followed diagnostic cut-off values exist for classifying individuals as 'food neophobics' and 'food neophilics' based on their FNS score (12) . Often the sample mean (or median) FNS score (18,24,(27)(28)(29) , or the score 35 (30) , has been used as the cut-off value to categorize study participants into two groups. Another common practice is to use the mean plus/minus one standard deviation as cut-off values (11,14,31,32) to form three groups.…”

Objective: Food neophobia has been associated with decreased consumption of vegetables mainly among children. We hypothesized that food neophobia in adults is also associated with lower overall dietary quality and higher BMI. Design: Data for the present cross-sectional analyses were derived from parents in a follow-up family study. Setting: The STEPS study, a longitudinal study of health and development of a cohort of children born in south-west Finland. Subjects: The parents, 1178 women (age 19-45 years, mean 32·2 years) and 1013 men (age 18-57 years, mean 34·1 years), completed a questionnaire at home when their child was 13 months old. The questionnaire included the Food Neophobia Scale (FNS; range 10-70), the Index of Diet Quality (IDQ; range 0-16) and a measure of fruit and vegetable consumption. At that time the participants' height and weight were also measured by a research nurse to calculate BMI. ) as tested by one-way ANOVA, with all P values <0·001 in women and <0·05 in men. The food neophobics followed a diet lower in nutritional quality than did the food neophilics, especially regarding vegetables. Conclusions: Food neophobia may complicate adaptation to dietary recommendations and predispose to overweight.

“…Knaapila et al (2011) reported that (especially in women) this attitude appears to be strongly genetically determined. The results of the studies conducted so far on gender differences are still quite inconclusive: Some authors have found that women are more neophobic than men (Frank and van der Klaauw, 1994), some authors described instead the contrary (Tuorila et al, 2001), whilst some others failed to find any differences at all (Flight et al, 2003; Nordin et al, 2004; Meiselman et al, 2010; Demattè et al, 2013). A clearer link has instead been described between food neophobia and age.…”

“…This scale has been successfully used to predict people’s attitude toward new foods and the expected liking of food products, and has been adapted for children administration (“Children Food Neophobia Scale”, CFNS; Pliner, 1994). It has also been translated into different languages and cultures (e.g., for Italian, see Demattè et al, 2013; for Spanish, see Fernández-Ruiz et al, 2013; for Chilean, see Schnettler et al, 2013; for Finnish, see Tuorila et al, 2001; for Japanese, see Yamada et al, 2012). Recently, the FNS has also been adapted to the fruit and vegetable domain (“Fruit and Vegetable Neophobia Instrument”, FVNI; Hollar et al, 2013).…”

“…The FNS can be used to determine neophobia classes by using one standard deviation from the group mean as the splitting criterion (Pliner and Hobden, 1992; Falciglia et al, 2000; Tuorila et al, 2001), by median split (Mustonen et al, 2012; Raudenbush and Capiola, 2012; Yamada et al, 2012), or else by tertiles split (Raudenbush et al, 2003; Tuorila and Mustonen, 2010; Capiola and Raudenbush, 2012; Fernández-Ruiz et al, 2013). Additional new approaches have also been tested recently, for example the segmentation based on Principal Component Analysis (PCA; Demattè et al, 2013; Fernández-Ruiz et al, 2013). …”

Food neophobia and its relation with olfaction

Food neophobia, that is the reluctance to try novel foods, is an attitude that dramatically affects human feeding behavior in many different aspects among which food preferences and food choices appear to be the most thoroughly considered. This attitude has an important evolutionary meaning since it protects the individual from ingesting potentially dangerous substances. On the other hand, it fosters an avoidance behavior that can extend even toward useful food elements. A strong link exists between food neophobia and both the variety in one person’s diet and previous exposures to different foods. In this review, the more recent findings about food neophobia will be concisely described. Given the suggested connection between the exposure to different foods and food neophobia, this review will focus on the relation between this attitude and human chemosensory abilities. Olfaction, in particular, is a sensory modality that has a central role in flavor perception and in food preference acquisition. Therefore, the latest evidences about its relation with food neophobia will be discussed along with the applied and cognitive implications.

Modulation of olfactory-driven behavior by metabolic signals: role of the piriform cortex

et al. 2018

Olfaction is one of the major sensory modalities that regulates food consumption and is in turn regulated by the feeding state. Given that the olfactory bulb has been shown to be a metabolic sensor, we explored whether the anterior piriform cortex (aPCtx)-a higher olfactory cortical processing area-had the same capacity. Using immunocytochemical approaches, we report the localization of Kv1.3 channel, glucose transporter type 4, and the insulin receptor in the lateral olfactory tract and Layers II and III of the aPCtx. In current-clamped superficial pyramidal (SP) cells, we report the presence of two populations of SP cells: glucose responsive and non-glucose responsive. Using varied glucose concentrations and a glycolysis inhibitor, we found that insulin modulation of the instantaneous and spike firing frequency are both glucose dependent and require glucose metabolism. Using a plethysmograph to record sniffing frequency, rats microinjected with insulin failed to discriminate ratiometric enantiomers; considered a difficult task. Microinjection of glucose prevented discrimination of odorants of different chain-lengths, whereas injection of margatoxin increased the rate of habituation to repeated odor stimulation and enhanced discrimination. These data suggest that metabolic signaling pathways that are present in the aPCtx are capable of neuronal modulation and changing complex olfactory behaviors in higher olfactory centers.
