When your brain reacts strongly to the taste of food right away, it seems to dial down the later dopamine surge from your stomach feeling full—like your brain is balancing taste and nutrition.
Scientific Claim
Immediate dopamine release in wanting-related brain regions is associated with reduced post-ingestive dopamine release in the dorsal striatum, suggesting a possible regulatory interaction between sensory and nutritional reward signals.
Original Statement
“Immediate dopamine release in these wanting-related regions was inversely correlated with, and presumably inhibited, post-ingestive release in the dorsal striatum.”
Evidence Quality Assessment
Claim Status
overstated
Study Design Support
Design cannot support claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The phrase 'presumably inhibited' implies causation or mechanism without experimental evidence. The abstract only reports correlation. Verb strength must be downgraded to 'association' and speculative language removed.

Food Intake Recruits Orosensory and Post-ingestive Dopaminergic Circuits to Affect Eating Desire in Humans.
When you first taste something yummy, your brain releases dopamine right away, but the more your brain gets that initial taste rush, the less dopamine it releases later when your body digests the food — like your brain is saying, 'I got the hint, no need to keep signaling for more.'
