Claim by claim

A source study was identified, but the study's evidence could not be prepared for claim assessment. The claims below have not been assessed.

Claim 1 of 5Not checkedA new study from UC San Francisco shows that an understudied slow dopamine pathway connecting the gut and brain helps the brain connect a flavor with the beneficial effects that follow ingesting it.View evidenceHide evidence

Not checked

A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.

Claim 2 of 5Not checkedThe article says the researchers delivered sugar water or a milkshake-like liquid directly into mice' stomachs and found that the nutrients triggered a strong and sustained dopamine release in the anterior basolateral amygdala.View evidenceHide evidence

Not checked

A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.

Claim 3 of 5Not checkedWhen the pathway was blocked, mice kept eating normally but could no longer learn that a new flavor predicted calories; when dopamine fibers in the BLA were artificially stimulated after a calorie-free flavor, mice learned to prefer it.View evidenceHide evidence

Not checked

A source study was identified, but the evidence comparison for this claim was not completed. No verdict has been assigned.

Claim 4 of 5Not checkedHuman analyses described in the story found a similar pattern, with dopamine release or increased activity concentrated in the left side of the basolateral amygdala after milkshake or glucose consumption.View evidenceHide evidence

Claim 5 of 5Not checkedThe article says the researchers did not study GLP-1 drugs, and whether those drugs affect the pathway is unknown; Knight speculates they could reduce nutrient-triggered dopamine signaling and make food less reinforcing over time.View evidenceHide evidence
