Rainbow Tasting Passport

A no-pressure tasting game in which the child collects a stamp for every colour of fruit or vegetable they are brave enough to explore — by looking, smelling, licking, or tasting.

  1. Make a small paper “passport” with a page (or a box) for each colour: red, orange, yellow, green, purple/blue, white.
  2. Put out 2–3 fruits or vegetables in tiny pieces — one familiar favourite and one or two new or previously refused ones (a pepper strip, a pea pod, a slice of kiwi, a raw mushroom slice).
  3. Explore like food scientists before any eating: What colour is it? Is it bumpy or smooth? What does it smell like? Does it crunch or squish?
  4. Invite — never insist on — a tiny taste. The child chooses their own level: touch it, smell it, lick it, take a mouse-sized nibble, or eat it. A polite “no thank you” is always allowed, and so is spitting into a napkin.
  5. Any exploring earns a stamp or sticker on that colour’s page. Add a face the child chooses: yum, okay, or not yet.
  6. Bring the “not yet” foods back another day. Explain: “Tongues need lots of tries to learn a new food.”

Variation: go on a rainbow hunt at the shop or market — the child picks one fruit or vegetable of a colour missing from the passport to bring home and try.

Requirements

  • Space: Kitchen or dining table
  • Surface: Table with a wipeable surface or a plate for each taster
  • Materials: 2–3 fruits or vegetables cut small, paper for the passport, crayons, stickers or a stamp, napkins
  • Participants: 1 adult + 1 child; siblings and the adult should taste too
  • Supervision: Moderate — adult prepares the food safely and tastes alongside the child

Rationale & Objective

Children are naturally wary of new foods — food neophobia peaks in the preschool years — and the best-evidenced way through it is repeated, pressure-free taste exposure. Wardle and colleagues (2003) found that children offered a small daily taste of an unfamiliar vegetable for two weeks came to like and eat it more than children in a control group; classic work by Birch & Marlin (1982) showed preference rising with the number of exposures, with around ten tries often needed. Pressure backfires — Galloway and colleagues (2006) found that urging children to eat reduced intake and created negative feelings toward the food. The passport keeps the tries coming while leaving the child in charge, and the sticker rewards exploring rather than eating — never use dessert or other food as the prize. The activity serves the Head Start ELOF goal that children develop knowledge and skills that promote nutritious food choices, and the USDA’s preschool programme Grow It, Try It, Like It! uses the same look-touch-smell-taste approach.

Progress Indicators

  • Early: watches others taste; will look at or touch a new food but not bring it to the mouth; names only a few fruits and vegetables
  • Developing: smells and licks new foods; takes a tiny taste of some; names the colours and several fruits and vegetables; accepts a food being offered again after a “not yet”
  • Proficient: willingly takes a small taste of most new foods offered; describes taste and texture (sweet, sour, crunchy, juicy); says that eating different colours helps the body grow and stay healthy
  • Advanced: asks to try new foods or picks them at the shop; a previously refused food moves to “okay” or “yum”; notices which colours are missing from a meal and suggests one

Safety Notes

  • Choking risk — cut grapes, cherry tomatoes, and berries lengthwise into quarters, slice raw carrot and apple thinly or grate them, and always have the child seated while eating
  • Check for known allergies and introduce commonly allergenic foods (kiwi and some other fruits can cause reactions) in small amounts; stop and seek medical advice if you see hives, swelling, vomiting, or breathing difficulty
  • Wash produce and hands before tasting
  • Never force, bribe with dessert, or shame a refusal — pressure makes pickiness worse. The stamp is for exploring, not for swallowing
  • Ordinary pickiness is normal at 5. Talk to your pediatrician if your child accepts fewer than about 20 foods, gags on many textures, is losing weight, or mealtimes cause severe distress

Hints

  • Playfulness: give tastes funny scientist names (“the crunch test”, “the squeak test” for green beans), wear pretend lab goggles, and have the adult pull exaggerated thinking faces while tasting
  • Sustain interest: aim to fill one colour page at a time over weeks rather than everything at once; let the child choose the next mystery food; revisit “not yet” foods prepared a different way — raw, roasted, with a dip
  • Common mistake: counting only swallowing as success, or praising so heavily that it becomes pressure. Calm, matter-of-fact tasting alongside the child works best — your own eating is the strongest model
  • Limited space: no passport needed — offer one tiny “learning bite” beside the normal dinner and draw a dot on a fridge chart for any exploring
  • Cross-domain: sort foods by colour and count the stamps (maths); describe with taste and texture words (vocabulary); ask where each food grows — tree, bush, or under the ground (science); let the child wash and tear leaves (fine motor)
  • Progression: look and touch → smell → lick → tiny taste → a few bites → helping choose and prepare a new fruit or vegetable for a family meal
