Food Neophobia Scale (FNS)
Food Neophobia Scale · Also known as: FNS, neophobia
The Food Neophobia Scale is a 10-item self-report instrument measuring the degree to which individuals are reluctant or fearful of trying new foods. Developed by Pliner and Hobden in 1992, the FNS measures food neophobia—an aversion to unfamiliar foods—which is influenced by both evolutionary factors (caution toward unknown foods) and learned behaviors. The scale is widely used in nutrition, food science, and psychology research examining dietary diversity, food acceptance, and barriers to healthy eating.

When to use it
The FNS is used in nutrition and food science research examining determinants of dietary variety, food acceptance, and barriers to healthy eating. Clinical applications include: assessment of food acceptance in patients requiring dietary modification (renal diet, low-FODMAP, restrictive diets) to anticipate adherence challenges; evaluation of nutrition education interventions promoting dietary diversity or novel foods; and research examining links between food neophobia and dietary quality or nutritional adequacy. The FNS is also used in food marketing research, consumer studies, and developmental psychology examining food acceptance across ages.
Strengths & limitations
- Well-validated trait measure—extensively tested in diverse populations (children, adolescents, adults, cross-cultural) with reliable factor structure and internal consistency (Cronbach's α typically 0.70–0.80).
- Brief and practical—10 items, 3–5 minutes; easy to administer in surveys or clinical settings.
- Predicts dietary patterns—higher FNS scores are associated with lower vegetable intake, lower dietary diversity, more restricted food choices, and potentially lower overall dietary quality.
- Relevant across age groups—food neophobia appears in childhood and persists into adulthood; the FNS is applicable from late childhood onward.
- Modifiable trait—while neophobia has genetic and developmental origins, it can be reduced through repeated exposure, peer modeling, and positive food experiences; interventions targeting neophobia can increase food acceptance.
- Culturally applicable—food neophobia is observed across cultures, though degree varies; FNS has been translated and validated internationally.
- Informs intervention design—knowledge of neophobia levels enables tailored nutrition education (familiar-based approaches for high-neophobic; diversity-promoting approaches for low-neophobic).
- Measures trait, not state—FNS assesses general reluctance to try new foods; does not capture state-dependent acceptance (e.g., greater willingness in group settings or with trusted people).
- Limited specificity—does not identify which types of foods trigger aversion; some individuals fear novel vegetables but accept novel fruits, or reject unfamiliar cuisines but try novel preparations of familiar foods.
- Assumes 'new foods' are positive—neophobia is framed as avoidance, but caution around unfamiliar foods has protective value (avoidance of harmful substances); the scale does not distinguish adaptive caution from maladaptive restriction.
- Does not assess actual food exposure—high neophobia score does not directly measure food intake diversity; individuals may have high neophobia but consume diverse foods due to external factors (necessity, family, cultural immersion).
- Limited biological/physiological data—FNS is self-report and does not measure physiological responses (taste receptors, satiety hormones) that may influence actual food acceptance.
- Cultural and socioeconomic context—food neophobia may be rational response in contexts of food insecurity or limited access to novel foods; Western assumptions about neophobia as maladaptive may not apply universally.
- Does not distinguish between neophobia and food pickiness—related but distinct constructs; neophobia is fear/aversion to novel foods, while pickiness is selective food acceptance based on sensory properties (texture, flavor).
Frequently asked
Is food neophobia the same as being a picky eater?
They are related but distinct. Food neophobia is specific fear/reluctance to try new or unfamiliar foods. Pickiness (selective eating) is broader—selectivity based on sensory properties (texture, taste, appearance) regardless of novelty. Someone can be neophobic but accept many foods once familiar; someone can be non-neophobic but picky about textures or flavors. Both can limit dietary variety but through different mechanisms.
Can food neophobia be overcome?
Yes, to some degree. Food neophobia is trait-like but modifiable. Repeated, positive exposure to novel foods (especially with peer modeling or in positive social contexts) can increase acceptance. This process is gradual—often requiring 10–15+ exposures—but evidence shows neophobia can decrease with age, travel, cultural immersion, and structured interventions like taste education.
What is a 'high' score on the Food Neophobia Scale?
Using the sum score (10–70), scores >50 indicate high neophobia; scores 30–50 indicate moderate; scores <30 indicate low. Using mean (1–7), mean >5 is high, 2.5–5 is moderate, <2.5 is low. High-neophobic individuals (scores >50 or mean >5) are strongly reluctant to try new foods and prefer familiar options.
Is food neophobia genetic?
Food neophobia has both genetic and environmental origins. Twin studies suggest heritability around 50%, meaning genes influence but do not determine neophobia level. Environmental factors (parental food exposure, cultural context, peer influence, early food experiences) also shape neophobia. This mixed etiology means interventions addressing exposure and social influence can reduce neophobia even in genetically predisposed individuals.
Does food neophobia affect nutrition in adults?
In some individuals, yes. High food neophobia is associated with lower vegetable intake and less dietary diversity, which could impact nutrition if resulting in inadequate micronutrient intake. However, many high-neophobic individuals consume nutritionally adequate diets through familiar foods. Neophobia is a risk factor for low dietary diversity but not a direct determinant of nutritional adequacy.
Can diet-related health conditions increase food neophobia?
Possibly. Individuals requiring restrictive diets (renal, low-sodium, low-FODMAP) may become more neophobic due to anxiety about 'safe' foods or unpleasant experiences with unfamiliar diet foods. Additionally, gastrointestinal conditions or food sensitivities may increase caution around novel foods. Assessment of neophobia in context of medical conditions is important; support addressing both the medical diet and food anxiety may be needed.
