If your child eats a very small number of foods, introducing something completely new can sometimes feel like a huge challenge.

You might hear advice such as, “Just keep offering it,” or “They’ll eat it when they’re hungry enough.”

But for many neurodivergent children and adults, eating isn’t that simple.

Differences in sensory processing, food texture, smell, taste, appearance, temperature and predictability can all influence whether a food feels safe and manageable to eat.

This is where food chaining can be a useful approach.

Food chaining is a gradual, low-pressure way of helping someone become more comfortable with new foods by connecting them to foods they already accept.

Rather than jumping from a familiar food to something completely different, you build a bridge between the two.

What is food chaining?

Food chaining involves starting with a food that is already accepted and gradually introducing foods that share similarities.

These similarities might include:

• flavour
• texture
• colour
• shape
• temperature
• brand
• appearance
• smell
• preparation method.

The idea is to make the new food feel familiar enough to be manageable, rather than completely unfamiliar and overwhelming.

For example, if someone reliably eats one particular brand of chicken nuggets, the next step might not be homemade chicken breast.

Instead, you might explore another brand of chicken nugget with a slightly different coating.

From there, you could potentially move towards a different style of crumbed chicken.

Each step creates a small change while maintaining something familiar.

A simple food-chaining process

Food chaining doesn’t need to be complicated. The key is to make one small change at a time and allow the person to become comfortable before moving to the next step.

Step 1: Start with a safe or accepted food

Begin with something the person already eats reliably.

Don’t start with the food you wish they would eat.

Start with what is already working.

For example:

Preferred chicken nugget

This is your starting point.

Step 2: Work out what they like about it

Think about the characteristics that make the food acceptable.

Ask yourself:

• Is it crunchy?
• Is it soft?
• Is the flavour mild?
• Is it a particular colour?
• Is it a specific brand?
• Is it predictable every time?
• Is it served at a particular temperature?
• Is the food separated from other foods?
• Is the shape important?

These characteristics become your food-chain bridges.

For example, if crunch is important, choose another crunchy food rather than immediately introducing something soft.

Step 3: Choose one food that is very similar

Introduce a food that shares several characteristics with the accepted food.

For example:

Preferred chicken nugget → similar chicken nugget from another brand

The change may seem tiny, but that is the point.

A small change is often more manageable than a large one.

Step 4: Practise the new food without pressure

The person does not necessarily need to eat the new food straight away.

You might begin with simply having it:

near the accepted food → on the same plate → on a separate section of the plate → within reach → touched → smelled → tasted → eaten

Different people will move through these steps differently.

Some may skip steps completely.

Others may need to spend considerable time at one stage.

There is no required timeline.

Step 5: Repeat until the new food becomes familiar

Once a food has become comfortable, keep offering it.

The goal is to move from:

“This is new and unfamiliar.”

to:

“I know this food and I know what to expect.”

Familiarity can be particularly important when predictability is a significant part of someone’s eating preferences.

Step 6: Make another small change

Once the new food is established, identify the next small difference.

For example:

Preferred chicken nugget
↓
Different brand of chicken nugget
↓
Different crumb/coating
↓
Different shape or size
↓
Crumbed chicken pieces
↓
Different preparation of chicken

Each step maintains something familiar while introducing something new.

Step 7: Follow the person’s response

If the next step is too big, go back.

There is nothing wrong with returning to the previous food and trying a smaller change.

For example:

Food A → Food B → Food C

If Food C is consistently rejected, you might return to Food B and explore a different variation rather than pushing towards Food C.

Food chaining is not a race.

The goal is progress, not getting to the end of the chain as quickly as possible.

An example of food chaining

Let’s say someone reliably eats plain crackers but has a very limited range of grain foods.

Instead of immediately offering a completely different bread or cereal, you might create a chain such as:

Preferred plain cracker
↓
Same cracker in a different shape
↓
Different brand of plain cracker
↓
Cracker with a slightly different texture
↓
Wholegrain cracker with a similar texture
↓
Crispbread
↓
Toast with a familiar topping

But this is only an example.

Someone else might prefer to move from one brand of cracker to another brand and then stop there.

That is still useful progress.

The chain should be based on the individual, not on a predetermined list of foods they are expected to reach.

Another example: yoghurt

Imagine someone eats only one particular vanilla yoghurt.

Rather than jumping straight to fruit yoghurt, you might try:

Preferred vanilla yoghurt
↓
Same yoghurt in a different pack size
↓
Same brand, slightly different vanilla flavour
↓
Different brand with a similar texture
↓
Greek-style yoghurt with a similar consistency
↓
Yoghurt with a small amount of preferred fruit

Again, you may not need to progress through every step.

The purpose is to identify manageable opportunities for expansion.

What if the person won’t eat the new food?

That’s okay.

Food chaining does not require every new food to be eaten.

A person may first need to become comfortable with the food being present.

You might start with:

Seeing → being near → having on the table → having on the plate → touching → smelling → tasting → eating

This is sometimes called food exposure, and it can be an important part of the process.

For some people, being able to tolerate a food on their plate without distress is meaningful progress.

Don’t hide new foods

Food chaining is different from secretly adding unfamiliar ingredients to accepted foods.

If someone discovers that a trusted food has unexpectedly changed, this can undermine predictability and trust around eating.

Instead, aim for transparency.

You can offer the new food alongside a familiar food and allow the person to decide whether they want to interact with it.

Keep safe foods safe

A familiar food can provide predictability and reassurance.

It can therefore be helpful to continue offering accepted foods while introducing opportunities to explore something new.

Think:

familiar food + new opportunity

rather than:

new food or nothing.

This can help reduce pressure and make mealtimes feel safer.

How to know what the next food should be

A helpful way to choose the next food is to identify one characteristic you want to keep the same and one characteristic you want to change.

For example:

Current food	Keep the same	Change
Crunchy cracker	Crunch	Brand
Plain pasta	Texture	Shape
Vanilla yoghurt	Smooth texture	Brand
Chicken nugget	Crunchy coating	Shape
Toast	Crunch	Bread type

You don’t have to change everything at once.

In fact, changing one thing at a time can make the process much more manageable.

What if the food chain doesn’t work?

That’s okay.

Food chaining isn’t a straight line.

A food may be accepted one day and refused the next.

A change that seemed tiny to you may feel enormous to someone else.

You may also discover that the characteristic you thought mattered most isn’t actually the important one.

This isn’t failure.

It’s information.

You can use that information to adjust the next step.

Sometimes the change needs to be even smaller.

You might change:

• the brand
• the packaging
• the shape
• the size
• the temperature
• the cooking method
• the presentation
• the plate
• where the food is placed
• or whether foods are touching.

The smallest change may be the most successful starting point.

Food chaining is about more than “getting them to eat vegetables”

Expanding food variety can help someone access a broader range of nutrients.

But food exploration is also about participation, confidence and flexibility around food.

For a neurodivergent person, being able to tolerate different foods, brands, environments or preparation methods can make everyday eating easier.

It may make school, work, holidays, restaurants, social occasions or family meals more manageable.

And importantly, the goal doesn’t need to be achieving a particular idea of a “perfect” diet.

The goal is to help the person move towards their own best possible health and nutrition in a way that respects who they are.

There is no one “right” way to eat

This is particularly important when supporting neurodivergent people.

A person’s eating pattern needs to be considered within the context of their sensory preferences, needs, abilities, environment and individual circumstances.

For one person, increasing food variety may be the priority.

For another, the focus might be making sure they are eating enough.

For someone else, it may be improving nutritional adequacy within a very small range of accepted foods.

And sometimes the most meaningful goal is simply making eating less stressful.

Dietetic support should therefore be individualised rather than based on a generic list of foods someone “should” be eating.

How a dietitian can help with food chaining

A dietitian experienced in supporting neurodivergent people can help identify where the current food repertoire starts and determine realistic next steps.

This may include looking at:

• current accepted foods
• sensory preferences
• nutritional adequacy
• eating routines
• food preparation
• texture and consistency
• food presentation
• mealtime environment
• previous experiences with food
• and the individual’s own goals.

From there, food chains can be developed around foods that already feel familiar and achievable.

The process should be collaborative, flexible and responsive to the individual.

Take-Home Message

Food chaining can be a gentle way to support someone who has a limited food repertoire by building on foods they already know and accept.

The process is simple:

Start with a safe food → identify what makes it acceptable → choose a very similar food → introduce one small change → allow time for familiarity → repeat → gradually build the chain.

There is no need to rush.

For some people, progress might mean trying a new food.

For others, it might mean tolerating a food nearby, accepting a different brand or finding a nutritionally adequate alternative to a food they already eat.

There is no single definition of success.

The goal is to support each person to move forward towards their own unique health and nutrition best — in a way that is realistic, respectful and sustainable.
