Associations Between Perceived Tap Water Safety and Dietary Outcomes Among US Adults.
Article in Journal of the Academy of Nutrition and Dietetics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundWater safety and insecurity in the United States are growing public health concerns. Apprehension about water safety may impact consumption and use in food preparation, yet associations between water insecurity indicators and nutrition outcomes remain understudied.
objectiveThe aim of this study was to evaluate associations between water safety perceptions and diet quality and intake frequency of dietary components among US adults, and to assess how these associations vary with sociodemographic variables and cooking behaviors at home.
designA cross-sectional online survey was conducted. PARTICIPANTS/
settingAdults aged 18 years and older living across the United States (n = 4096) completed an online survey in November 2023.
main outcome measuresWater perceptions were measured using a 7-point Likert scale measuring agreement with the statement "My local tap water is safe to drink." Diet quality and intake frequency were assessed using the Prime Diet Quality Survey (PDQS-30). STATISTICAL ANALYSES: Generalized linear models, adjusted for sociodemographic variables, assessed associations between tap water safety perceptions and PDQS-30 scores (overall and stratified by "healthy/unhealthy" foods) and intake frequency of individual food groups. Sociodemographics and cooking frequency were evaluated as modifiers of the associations.
resultsTap water safety perceptions were not associated with total PDQS-30 scores (β = -0.27; 95% CI, -1.00 to 0.46; P = .47). For "unhealthy" foods only, not agreeing tap water was safe (compared with agreement) was associated with a 0.79-point higher PDQS-30 score (95% CI, 0.38 to 1.20; P < .001), driven by lower intake of red and processed meats and sweets/ice cream. Considering "healthy" foods only, not agreeing that tap water was safe (compared with agreement) was associated with a 1.06-point lower PDQS-30 score (95% CI, -1.83 to -0.29; P = .007), driven by lower intakes of fruits/vegetables and poultry. This association of lower intake of "healthy" foods was observed among US adults living in urban and rural areas, but not suburban areas, and for those cooking dinner at home fewer than 7 days per week; no modification by urbanicity and cooking at home was observed for "unhealthy" foods.
conclusionsTap water safety perceptions were associated with lower intake of some foods classified as unhealthy, and some foods classified as healthy in this sample of US adults. Urbanicity and cooking dinner from home modified the associations with "healthy" foods only, highlighting the complex social and environmental aspects of water insecurity and suggesting that tap water safety perceptions could be a barrier to healthy diets in some populations.
