Gut microbiota bridging spicy food intake and obesity: evidence from the China Multi-Ethnic Cohort (CMEC) study.
Article in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundObesity has emerged as a major global public health issue, associated with increased rates of chronic disease and death. Previous studies have reported an association between spicy food intake and obesity. However, existing studies still have several limitations, including a shortage of detailed dietary surveys, insufficient accounts for the effects of different types of chili peppers and fatty acids on obesity, and the mechanisms through which spicy food consumption influences the gut microbiota and adipokines have not been sufficiently investigated.
methodsA total of 950 adults, aged 30-79 years, were included from the China Multi-Ethnic Cohort (CMEC) study. Dietary intake data from the Food Frequency Questionnaire (FFQ) and 24-h recall were collected. A multivariable logistic regression model was used to estimate the association between spicy food intake and obesity. Evaluate the impact of spicy foods on gut microbiota through 16S rRNA gene sequencing analysis.
resultsAt the population level, we demonstrated that the intake of spicy food is a risk factor for obesity in Chinese Han population in cold regions of Yunnan Province (OR = 1.82, 95%CI: 1.11-2.99). At the animal level, we found that Capsaicin (CAP), a key active component of spicy foods, may not exert weight-loss effects when exposed to cold environments; instead, it appears to lipid accumulation and exacerbated disorders in gut microbiota dysbiosis and was modulated by leptin levels, both of which play critical roles in the development of obesity.
conclusionsSpicy food intake is a risk factor for obesity in Chinese Han population in cold regions of Yunnan Province. This may lead to increased lipid accumulation and exacerbate disorders associated with gut microbiota dysbiosis, which are modulated by leptin levels. Both factors influence the development of obesity.
