## First coffee experience
Most people dislike coffee at first and learn to love it.
## Scientists' discovery
Scientists say the reason may be a slow dopamine signal from the gut that teaches the brain to like flavours linked with calories.
## Flavour-nutrient learning
The brain learns to associate a particular taste with nutritional benefits after consumption.
## Dopamine pathway
Gut sends signals to brain triggering slow dopamine release in anterior basolateral amygdala.
## Mice study results
Disrupted pathway made mice struggle to develop preferences for nutrient-linked flavours.
## Dopamine role
Dopamine helps brain learn which flavours are worth returning to, not just make food taste better.
## Coffee explanation
This pathway explains why bitter foods like coffee become enjoyable after repeated exposure.
## Study limitations
The study does not establish this pathway directly causes human coffee preference.
## Key finding
Dopamine pathway provides biological explanation for developing food preferences over time.
## Coffee's journey
Coffee was never meant to be loved at first sip; it grows on you over time.
## Key takeaway

A gut-to-brain dopamine pathway explains how people develop taste preferences for bitter foods like coffee after initial dislike.
