The review compared repeated taste exposure with strategies that paired vegetables with rewards or preferred flavors. Researchers measured vegetable liking, acceptance, and the amount participants actually ate.
What the studies measured
Repeated taste exposure increased intake of the target vegetable.
?There is no universal correct number of exposures
Taste exposure is not pressure
In these studies, exposure meant repeated opportunities to taste the target vegetable.
The review does not support keeping someone at the table until the plate is empty or increasing pressure after refusal. It also does not establish that merely seeing a vegetable on the plate produces the same effect as tasting it.
Limits of the evidence
Effects varied with age, starting preference, vegetable, and intervention design.
Many studies involved infants or children; adult evidence was limited. The review did not conclude that everyone likes a vegetable after the same number of exposures. Increased intake also does not necessarily mean that participants rated the vegetable as more enjoyable.
A bounded home test
Without forcing a bite, offer a small amount of the same vegetable several times and record whether intake or distress changes.
How MorselFlow fits
A photo can keep whether the food appeared—not only whether it was finished.
MorselFlow is not a picky-eating treatment. Looking across weeks of photos can bring back how one vegetable appeared in different dishes.
The day it came a little closer still belongs to the meal flow.
