The Claim
Acute psychological stress is associated with reduced effective connectivity from the bed nucleus of the stria terminalis to the nucleus accumbens, orbitofrontal cortex, and dorsal mid-insula during exposure to food cues in healthy adults.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When healthy adults experience acute psychological stress, the communication between the bed nucleus of the stria terminalis and the nucleus accumbens, orbitofrontal cortex, and dorsal mid-insula decreases during exposure to food cues.
See the scientific wording
Acute psychological stress is associated with reduced effective connectivity from the bed nucleus of the stria terminalis (BNST) to the nucleus accumbens, orbitofrontal cortex, and dorsal mid-insula during exposure to food cues in healthy adults, suggesting stress may dampen top-down regulatory signaling within a neural circuit involved in reward valuation and interoceptive processing.
When a person experiences acute stress, the brain's stress center sends weaker signals to areas that evaluate how rewarding food is and how the body feels internally, making it harder to control urges to eat based on cues like sight or smell.
What the research says
1 studyStudy: Bed nucleus of the stria terminalis connectivity during food cue and taste processing under stress
When people are stressed, their brain’s stress center (BNST) talks less to the areas that decide how much they want food and how their body feels, making food cues seem more tempting or harder to ignore.
