Expected benefits of increasing taxes to nonessential energy-dense foods in Mexico: a modeling 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. 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
backgroundIn 2014, Mexico implemented an 8% tax on non-essential energy-dense foods (NEDFs) exceeding 275 calories per 100 g to improve dietary quality and reduce obesity prevalence. While this tax has shown promising results in reducing purchases of these items and decreasing obesity rates in children, its potential may be limited by the relatively low tax rate. We aimed to assess the potential impact of increasing the existing NEDF tax on body weight (kg), body mass index (BMI), obesity prevalence, and obesity cases in the Mexican adult population.
methodsUsing data from the Mexican 2018 National Health and Nutrition Survey (ENSANUT-2018), and a microsimulation mathematical model that translates adult energy balance into body weight changes, we analyzed the potential impact on obesity over 10 years. Our final sample included 15,109 participants, representing approximately 76,221,919 adults aged 20 and older in Mexico.
resultsWe found that doubling the existing tax (16%) could result in an average weight reduction of 0.4 kg and a 3.2% reduction in obesity prevalence over 10 years. If the NEDF tax was quadrupled (32%), an average weight loss of 1.2 kg and an 8.8% reduction in obesity prevalence could be expected. Males, low-income individuals, and adults aged 20 to 39 years would benefit the most, showing a higher expected reduction in obesity.
conclusionsVery few examples of taxation on NEDFs exist worldwide, and Mexico has been a key example. Policymakers should consider a tax reform that increases the current NEDFs tax to achieve larger health benefits.
