What is food chaining, and does it work?

Food chaining is a gentle approach feeding therapists use to slowly widen a picky eater's diet by building tiny bridges from foods they already accept.

Instead of introducing a totally new food, you make the smallest possible change to a current safe food — the same nugget brand in a different shape, the same cracker in a new size, a fry cut a little differently, a plain waffle turned into sticks. Each small step shares a texture, flavor, or brand with something already trusted, so it feels familiar instead of scary. Over many small links, the list can grow without a single high-stakes "try this new thing" moment.

Does it work? For many kids, yes — gradually, and best with zero pressure (the food is offered, never forced, and it's completely fine if it's ignored). It's slow by design. It won't fix severe ARFID alone, but as a low-pressure way to nudge the edges of a safe-food list, it's one of the few methods with real support behind it.
