Claim

Naming a dish for its flavour rather than for what it lacks or for its health properties increases how often it is chosen, with the food unchanged.

Yes. Identically prepared vegetables were chosen 41% more often under a flavour label than a health-restrictive one, and 'meat-free' performed worse than almost every alternative tested.

Moderate evidenceHow ratings work

Why this rating: Replicated across dining halls and commercial partners with a plausible mechanism, but mostly single-setting trials measuring selection at the counter, and the industry-partnered work is less fully reported than peer-reviewed studies.

Supported by good-quality studies that point the same way, but with gaps: fewer studies, mostly observational data, or some inconsistency.

More often chosen under a flavour label than a health-restrictive oneUnited States, 2019. Source: Turnwald et al. (2019).Identically prepared vegetables. The food did not change; only the words did.

Explanation

Stanford dining-hall trials served the same vegetables under different labels. Flavour-focused labels beat health-restrictive ones by 41% and basic ones by about 25%.

The Better Buying Lab found 'meat-free' underperformed nearly every alternative name. Describing a dish by what is missing invites loss aversion and makes the taste harder to imagine.

The same effect runs the other way: people rated an identical mango lassi as markedly less enjoyable when it was labelled healthy.

Limitations
  • Measures what people select, not what they eat or what they do next time.
  • University dining halls and partner restaurants are specific settings.
  • Naming is not free: a name that oversells the dish will cost more in disappointment than it gains at the counter.
Methodology
  • Randomised label assignment with the food held constant, measuring selection at the point of choice.
