Abstract

CONTEXT: Sugar overconsumption and chronic stress are growing health concerns because they both may increase the risk for obesity and its related diseases. Rodent studies suggest that sugar consumption may activate a glucocorticoid-metabolic-brain-negative feedback pathway, which may turn off the stress response and thereby reinforce habitual sugar overconsumption. OBJECTIVE: The objective of the study was to test our hypothesized glucocorticoid-metabolic-brain model in women consuming beverages sweetened with either aspartame of sucrose. DESIGN: This was a parallel-arm, double-masked diet intervention study. SETTING: The study was conducted at the University of California, Davis, Clinical and Translational Science Center's Clinical Research Center and the University of California, Davis, Medical Center Imaging Research Center. PARTICIPANTS: Nineteen women (age range 18-40 y) with a body mass index (range 20-34 kg/m(2)) who were a subgroup from a National Institutes of Health-funded investigation of 188 participants assigned to eight experimental groups. INTERVENTION: The intervention consisted of sucrose- or aspartame-sweetened beverage consumption three times per day for 2 weeks. MAIN OUTCOME MEASURES: Salivary cortisol and regional brain responses to the Montreal Imaging Stress Task were measured. RESULTS: Compared with aspartame, sucrose consumption was associated with significantly higher activity in the left hippocampus (P = .001). Sucrose, but not aspartame, consumption associated with reduced (P = .024) stress-induced cortisol. The sucrose group also had a lower reactivity to naltrexone, significantly (P = .041) lower nausea, and a trend (P = .080) toward lower cortisol. CONCLUSION: These experimental findings support a metabolic-brain-negative feedback pathway that is affected by sugar and may make some people under stress more hooked on sugar and possibly more vulnerable to obesity and its related conditions.

  • Consuming high sugar beverages, smoking, and alcohol intake can dampen the physiological stress response in the short run, but are clearly damaging to health if maintained over the lifespan.

    “For example, consuming high sugar beverages (Tryon et al., 2015), smoking (Wardle et al., 2011) and alcohol intake (Stephens and Wand, 2012) can dampen the physiological stress response in the short run, but are clearly damaging to health if maintained over the lifespan.”

    From More than a feeling: A unified view of stress measurement for population science (2018) · cites this paper as Tryon et al., 2015

    The Discussion (page not provided) reports that sugar-sweetened beverages reduced stress-induced cortisol responses, supporting the short-term stress-response point. It links sugar overconsumption to health risks, but does not establish that maintaining beverage consumption over a lifespan is clearly damaging; it also says the study cannot distinguish acute from long-term effects. The smoking and alcohol claims have separate citations and are not attributed to this source. (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
