A systematic review and meta-analysis gathered comparative human studies of repeated tasting and conditioning strategies intended to increase vegetable liking, acceptance or intake.
Familiarity can grow
Repeated tasting moved vegetable intake in a positive direction.
?There is no universal correct number of exposures
Exposure is not pressure
Repeating an opportunity is different from forcing a meal.
The approach centers on small experiences of seeing, touching or tasting. It does not support keeping someone at the table until the plate is cleared or escalating pressure after refusal.
“Not tasted today” can still be one time the food appeared nearby.
Read it carefully
Much of the evidence centers on infants and children.
Adult studies are included, but repeated-exposure research often involves children. Effects vary by age and starting preference; not everyone learns to like a food after the same count.
The useful goal is not to manufacture liking, but to avoid turning one refusal into a permanent label.
What to keep
A first bite is not a final verdict on a food.
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.
