ARFID or Picky Eating? How Can You Tell the Difference?

“My child is an incredibly picky eater.” It is something I hear from parents all the time.

And picky eating can be a completely normal part of childhood.

But sometimes food avoidance becomes much more than simply preferring some foods over others. Parents may notice their child's list of accepted foods becoming smaller and smaller. Meals might cause significant anxiety. Their child may struggle to eat enough, avoid social situations involving food, or become frightened of choking or vomiting.

So when does picky eating become something we need to look at more closely?

First, what is ARFID?

ARFID stands for Avoidant/Restrictive Food Intake Disorder.

ARFID is an eating disorder involving avoidance or restriction of food that can affect a person's nutrition, growth, health and/or everyday life.

Unlike anorexia nervosa, the food restriction in ARFID is not driven by a desire to lose weight or change body shape.

Instead, eating difficulties are commonly related to:

• sensory sensitivities

• fear of consequences such as choking or vomiting

• low appetite or limited interest in food

• or a combination of these.

What does typical picky eating look like?

Many children go through periods of being selective with food.

They might suddenly decide they don't like broccoli.

They may eat something happily one week and reject it the next.

They might prefer familiar foods and be suspicious of something new on their plate.

This can be frustrating for parents, but the child is generally still able to eat enough food from enough different food groups to support their needs.

They can usually participate in family and social activities involving food, even if they don't eat everything offered.

And importantly, food doesn't create significant fear or distress.

When might it be more than picky eating?

Rather than focusing only on how many foods a child eats, I am interested in the impact their eating is having.

Some questions I might ask include:

Is their food range becoming smaller rather than gradually expanding?

Are they eating enough to support their growth and development?

Are there concerns about nutritional deficiencies?

Does eating cause significant anxiety or distress?

Do they fear choking, vomiting or becoming unwell?

Are sensory differences making many foods feel impossible to tolerate?

Are they avoiding school camps, sleepovers, parties or restaurants because of food?

Does the family need to bring specific foods everywhere?

Are meals becoming a major source of conflict or worry at home?

The answers to these questions often tell us much more than simply counting the number of foods a child eats.

“But they'll eat chips, biscuits and nuggets…”

This can be particularly confusing for families.

Parents sometimes wonder how their child could possibly have a feeding or eating difficulty when they happily eat foods such as crackers, chips, biscuits or chicken nuggets.

But many of these foods have something important in common.

They are predictable.

A cracker from the same packet usually looks, smells and tastes exactly like the cracker before it.

Compare that with a blueberry.

One blueberry might be sweet. The next could be sour. One is firm and another is soft. Occasionally there is a squishy one hiding in the container.

For a child with sensory sensitivities, that unpredictability can be genuinely difficult.

So a preference for packaged or beige foods doesn't necessarily tell us that a child is simply choosing “junk food”.

It may tell us something about what makes a food feel safe.

“They'll eat if they're hungry enough.”

This is a common piece of advice given to parents of selective eaters.

For a child with ARFID, it can be unhelpful and potentially risky.

If a child is frightened of choking, extreme hunger doesn't necessarily remove that fear.

If the texture of a food feels intolerable, hunger doesn't necessarily make the sensory experience easier.

And if a young person has very weak hunger cues, waiting for them to become hungry enough may not work at all.

Removing safe foods can sometimes result in the child simply eating less, rather than becoming willing to eat something unfamiliar.

Picky eating and ARFID aren't always completely separate

There isn't necessarily a clear line where picky eating ends one day and ARFID begins the next.

Some children have been selective eaters from a very young age and their eating gradually becomes more restricted.

Others experience a particular event, perhaps choking, vomiting or becoming unwell and suddenly become frightened of foods they previously ate.

This is why early support can be helpful when parents notice eating becoming increasingly difficult.

When should I seek some extra help?

Consider speaking with your GP or paediatrician if your child's eating is affecting their:

• growth or weight

• nutritional intake

• energy levels

• physical health

• ability to participate in everyday activities

• school experience

• social life

• emotional wellbeing

• or family life.

You also don't need to wait until things become severe before asking for help.

Sometimes parents simply know:

“Food has become much harder than it should be.”

That is worth exploring.

Helping rather than forcing

Whether a child has ARFID, significant selective eating or is simply finding food difficult at the moment, I prefer to approach eating with curiosity.

Instead of asking:

“How do we make them eat this?”

we can start by asking:

“What is making this food difficult?”

Is it the smell?

The texture?

The uncertainty?

Are they worried about choking?

Do they feel full very quickly?

Are they overwhelmed at the table?

Do they struggle to recognise hunger?

That change in question can completely change the way we support a young person.

Because when we understand why eating is difficult, we can start finding ways to make it easier.

And from there, we can gradually help a young person build confidence with food — without turning every meal into a battle.

Not sure if it's ARFID or picky eating?

You don't need to have a diagnosis before asking for support.

If your child's food range is becoming increasingly limited, eating is causing anxiety or family stress, or you're simply concerned that they're not getting what they need, an assessment can be a helpful place to start.

I work with children, adolescents and families to understand why eating is difficult and develop practical, low-pressure strategies to support nutrition, food variety and confidence around eating.
