How to teach children to taste new food
TL;DR
Food neophobia — fear of new food — is evolutionarily normal and typically peaks between ages 2 and 6. Research shows that neutral repeated exposure (8-15 tastes) is the most effective strategy. Coercion and rewards do not work. Letting children prepare the food themselves works significantly better.
Your child freezes, wrinkles their nose, and says "I don’t want to taste that." You know it’s healthy, you know it tastes good, and you have done your best to present it appealingly. Still: no. This is food neophobia in action — and it is actually completely normal. In fact, it is evolutionarily smart. This guide explains what research really knows about children’s resistance to new food, and what actually works — and what doesn’t.
What is food neophobia — and why do children have it?
Food neophobia is not pickiness — it is an evolutionary protection system. And it is normal.
Food neophobia literally means: fear of new food. It is a universal human tendency strongest between ages 2-6. Evolutionarily, this makes perfect sense: a child starting to eat independently who is skeptical of unfamiliar foods is better protected from eating poisonous plants and berries.
Research from NCBI (2014) shows that genetics play a major role in the degree of food neophobia. Twin studies show that 72% of the variation in food neophobia is explained by genetic factors — not parenting. This is an important point: your parenting is not the cause of your child’s pickiness. Biology is.
This also means that neophobia naturally decreases with age. Most children become significantly more open to new food after the age of 7-8 — regardless of what parents do or don’t do.
Research on exposure: 8-15 tastes for acceptance
It takes 8-15 neutral exposures to a new food item before most children accept it. Patience is not just a virtue — it is a strategy.
The key finding from the Monell Chemical Senses Center in Philadelphia is that taste exposure works — but it requires time and a neutral approach. Studies show that children consistently presented with a new food item (without coercion) gradually increase their acceptance. Typically, 8-15 exposures over time are required.
The crucial detail is: the exposure must be neutral. Neither positive pressure ("Just try one bite, it's healthy!") nor negative pressure ("Just eat it now!") works — and can actually worsen resistance.
Practically: put the vegetable on the table. Let the child see it, touch it, smell it. Once a week for three months. It is not eaten — but these are exposures working in the background.
The IKEA effect: children eat what they make themselves
Children are significantly more likely to eat a dish they have helped make — no matter what it contains.
One of the strongest findings in research on children and food is what is called the "IKEA effect" — the increased value we assign to things we have created ourselves. In the food context: children who have participated in preparing a dish rate it as tastier and are more willing to eat it than children who have not participated.
A study published in Appetite (2014) showed that children who made a vegetarian stew themselves ate twice as much of it compared to a control group — even though they said they didn’t like vegetables.
It is the single factor with the greatest effect on food receptiveness. And that is exactly why we recommend letting children actively participate in cooking from an early age. Start with simple tasks: wash vegetables, peel carrots, stir the pot. Use a good kitchen set adapted to the child’s hands, so it’s a positive experience.
What doesn’t work — and can make it worse
Three strategies most parents try, which research shows don’t work — and can increase resistance.
- Force — "You sit here until you’ve eaten it" creates a negative association with the food and increases neophobia in the long term. Research is clear: force doesn’t work.
- Rewarding with sweets — "If you eat your broccoli, you get dessert" signals two things: that broccoli is bad (otherwise it wouldn’t need a reward) and that dessert is the real food. Both are counterproductive.
- Hiding vegetables — smoothies with spinach, pasta sauce with pureed zucchini. It works temporarily, but it doesn’t expose the child to the vegetable and doesn’t build acceptance.
Common to all three: they don’t solve the problem, they bypass it. And neophobia is not solved by bypassing — it is solved by gradual, neutral exposure over time.
Types of picky eating: sensory vs. habit-based
Not all picky eating is the same — and the strategy should depend on the type.
Sensory picky eating is about texture, temperature, smell, and appearance. These children have stronger sensory processing and physically react to foods. Strategy: gradual sensory exposure without pressure. Let the child play with the food, touch it, smell it — before tasting.
Habit-based picky eating is about recognition and predictability. These children want familiar dishes. Strategy: introduce new food as a small addition to familiar dishes — a new vegetable alongside the well-known pasta, not instead of it.
Both types benefit from participating in cooking. It is hard to refuse a dish you have cut the vegetables for yourself. Introduce cooking early with age-appropriate kitchen tools and a learning tower for safe access at the table.
What you can do starting tomorrow
Three concrete, research-based strategies you can start without conflicts and without pressure.
- Put new food on the table without expectation — just let it be there. No comments, no encouragement. It is simply present.
- Food play — play with vegetables as materials. Cut cucumber into circles, make faces from tomatoes and olives. Tactile contact is exposure.
- Cook together — let the child participate in preparing the food you want the child to eat. It is the strongest single intervention we know.

Food neophobia is a normal, biological phenomenon — not a parenting failure. It is not solved with pressure, force, or rewards. It is solved with time, neutral exposure, and — above all — by letting the child participate in the kitchen.

Frequently Asked Questions
What is food neophobia?
Food neophobia is fear of or resistance to new and unfamiliar food. It is evolutionarily normal and typically peaks between ages 2 and 6. Research shows it is strongly genetically determined — it is not a sign of bad parenting.
When does food neophobia stop?
Most children become significantly more open to new food after the age of 7-8. Neophobia naturally decreases with age — but the degree varies greatly from child to child and is largely genetically determined.
Does hiding vegetables in food work?
In the short term, it can increase vegetable intake — but it does not build acceptance. The child is not exposed to the vegetable’s appearance, taste, or texture and does not learn to tolerate it. Long-term studies show no benefit from this strategy.
How many times does a child need to taste something before accepting it?
Research from the Monell Chemical Senses Center suggests 8-15 neutral exposures over time are typically necessary for gradual acceptance. It requires patience and consistency — and no pressure during each exposure.
Does it help to let children make the food themselves?
Yes — it is actually the single factor with the greatest documented effect. Children who participate in food preparation eat on average twice as much of the dish compared to children who did not participate, according to research published in Appetite (2014).
