Claim 1 of 5Not coveredIn experiments, 108 participants ate just over 100 grams of white-wheat bread, and researchers tracked their glycemic response for two hours.View evidenceHide evidence

Why this verdict

The abstract-level profile verifies the n=108 glucose/carbohydrate-challenge experiment and serial glucose time-course assessment, but it does not specify that participants ate just over 100 grams of white-wheat bread or that glycemic response was tracked for exactly two hours. Those protocol details require fuller paper evidence.

Study evidence

Following a carbohydrate challenge, participants in the Social condition exhibited lower glucose perturbation amplitude and faster recovery than participants in the Alone condition (n = 108).

“In a set of preregistered experiments, we found that glucose homeostasis following a carbohydrate challenge is more efficient in a Social condition than an Alone condition, exhibiting lower perturbation amplitude and faster recovery ( n = 108).”
Claim 2 of 5SupportedA new study published in Science Advances found evidence that eating with others could help the body balance blood sugar levels.View evidenceHide evidence

Why this verdict

The abstract-level profile supports that a preregistered human experiment found more efficient glucose homeostasis in a Social condition than an Alone condition after a carbohydrate challenge, with lower perturbation amplitude and faster recovery. The story’s hedged wording, “could help,” is broadly consistent with the experimental framing, though abstract-level evidence does not provide effect sizes or full protocol details.

“In a set of preregistered experiments, we found that glucose homeostasis following a carbohydrate challenge is more efficient in a Social condition than an Alone condition, exhibiting lower perturbation amplitude and faster recovery ( n = 108).”
Claim 3 of 5SupportedWhen participants ate the bread with a close companion, blood sugar levels spiked less and returned to baseline faster than when they ate alone.View evidenceHide evidence

Why this verdict

The profile supports the core finding that the Social condition had lower glucose perturbation amplitude and faster recovery than the Alone condition after a carbohydrate challenge. However, the abstract does not independently verify the story’s more specific operational detail that the other person was a “close companion” or that the challenge food was bread.

“In a set of preregistered experiments, we found that glucose homeostasis following a carbohydrate challenge is more efficient in a Social condition than an Alone condition, exhibiting lower perturbation amplitude and faster recovery ( n = 108).”
Claim 4 of 5SupportedThe authors argue that the findings provide a proof of concept for 'social physiology,' a framework for understanding how social connection may affect human bodily regulation.View evidenceHide evidence

Why this verdict

The profile explicitly says the authors interpret the cross-domain findings as evidence for a principle or framework of “Social Physiology,” in which social proximity improves physiological homeostatic efficiency. The story frames this as the authors’ argument and hedges it appropriately.

Study evidence

Social proximity during a controlled cold challenge was associated with more efficient thermoregulation (lower perturbation amplitude and faster recovery) compared with being alone (n = 116).

“The social benefit in homeostasis replicated in thermoregulation during a cold challenge ( n = 116)…”
Claim 5 of 5SupportedThe story says the team also ran parallel experiments in 116 participants on cold exposure and in 115 adults plus 56 mother-infant pairs on a stress challenge, finding that the presence of another person improved temperature regulation and reduced arousal responses.View evidenceHide evidence

Why this verdict

The profile supports parallel preregistered experiments/generalizations in thermoregulation during cold exposure with n=116 and sympathetic regulation during stress in adults with n=115 and infants with n=56. The story’s “improved temperature regulation” and reduced arousal-response framing is broadly consistent with more efficient thermoregulation and sympathetic regulation, though the abstract-level profile does not verify the specific phrase “mother-infant pairs.”

What the story carried across

Nothing material from the study was dropped.

5 things the story did carry across
  • Glucose experiment: social proximity versus being alone after a carbohydrate challenge in n=108, with lower perturbation amplitude and faster recovery in the Social condition.
  • Cold-challenge experiment: social proximity benefit generalized to thermoregulation during cold exposure in n=116.
  • Adult stress experiment: social proximity benefit generalized to sympathetic regulation during stress in adults, n=115.
  • Infant stress experiment: social proximity benefit generalized to sympathetic regulation during stress in infants, n=56.
  • The authors’ broader interpretation: the experiments are presented as proof of concept for a cross-domain principle of “Social Physiology.”

In plain English

Preregistered human experiment (n = 108) compared a Social proximity condition to an Alone condition during/after a carbohydrate challenge and reported that glucose homeostasis in the Social condition showed a smaller perturbation amplitude and faster recovery time course than in the Alone condition.

Key findings

  • Following a carbohydrate challenge, participants in the Social condition exhibited lower glucose perturbation amplitude and faster recovery than participants in the Alone condition (n = 108).
“In a set of preregistered experiments, we found that glucose homeostasis following a carbohydrate challenge is more efficient in a Social condition than an Alone condition, exhibiting lower perturbation amplitude and faster recovery ( n = 108).”
What this piece can’t prove
  • Summary is based solely on the abstract; full methods, statistical details, and supplementary materials were not available in the provided evidence.
  • Unclear participant population (age, health status), exact measurement modality, timing of glucose sampling, or whether groups were randomized/blinded.

1 further detail could not be confirmed from the summary.

In plain English

In a preregistered human experiment (n = 116), social proximity during a controlled cold challenge was associated with more efficient thermoregulatory homeostasis: the Social condition showed smaller perturbation amplitude and faster recovery of physiological temperature regulation than the Alone condition, reported as a replication/generalization of the social benefit to homeostasis.

Key findings

  • Social proximity during a controlled cold challenge was associated with more efficient thermoregulation (lower perturbation amplitude and faster recovery) compared with being alone (n = 116).
“The social benefit in homeostasis replicated in thermoregulation during a cold challenge ( n = 116)…”
What this piece can’t prove
  • Unclear from abstract whether assignment to Social vs Alone was randomized, blinded, or how social proximity was operationalized (e.g., presence of partner, stranger, physical contact).

In plain English

In a preregistered human adult experiment (n = 115), the authors report that sympathetic nervous system regulation during an acute stress challenge was more efficient in a Social versus Alone condition, described as a replication of the social benefit to homeostasis observed in other physiological domains.

In plain English

Preregistered interventional experiment in human infants (n = 56) reported that sympathetic regulation during an experimentally induced stress challenge was more efficient in a Social condition than an Alone condition, characterized by lower perturbation amplitude and faster recovery.

Key findings

  • In a preregistered infant experiment (n = 56), sympathetic regulation during a stress challenge was more efficient in the Social than the Alone condition, showing lower perturbation amplitude and faster recovery.
“…and infants ( n = 56).”
What this piece can’t prove
  • Summary is based solely on the paper abstract; full methods, measures, and statistical results are not available here.
  • Unclear which infant-appropriate sympathetic measures and which stressor paradigm were used; replication and interpretation depend on those details.
