Neophobia means fear of the new. When this term is used with children in their response to food, it refers to the fear of new foods.
The neophobic stage is seen from around the age of 18 months; it peaks
at about two years, and then gradually becomes less strong through the
toddler and pre-school years.
It has been suggested that this food refusal response is of
evolutionary benefit. Infants who are just starting to be mobile will
not put new ‘non-foods’, that might be poisonous, into their mouths.
At the onset of the neophobic stage the toddler might reject foods that
are only slightly different from those that they usually eat, for
example:
- a broken biscuit may be rejected, but a whole biscuit accepted
- toast that is burnt around the edges may be rejected, but uniformly coloured toast will be accepted.
This extreme rejection occurs because,
at the early stages of the neophobic stage, toddlers are focusing on
the ‘local’ details of the food; that is how the food differs from the
prototype food that they have in their mind’s eye. As toddlers get
older, and learn that foods can differ slightly in appearance, but
still belong to the same category, then this extreme response
disappears (in most children but not all).
Rejection of previously accepted foods.
In a way the term fear of new foods is a little
misleading, because at this age toddlers tend to start to reject food
that they have eaten before, as well as refusing to try new foods.
The disgust response.
Food is also likely to be rejected at the neophobic stage
because of its texture. Toddlers might find the texture of some foods
slimy or lumpy, or too chewy. The texture of a food can be inferred by
the way that it looks. So toddlers are more likely to reject foods of
certain texture on sight.
If the children are:
- very sensitive to the feel of food in the mouth
- forced to eat foods that they have rejected
a strong disgust response to the food can also develop.
Most adults can remember their feelings of disgust at being made
to eat a food that they did not like. These foods are usually those
with an odd texture e.g. cauliflower cheese, tomatoes, liver.
