Shelf Space Devoted to Nutritious Foods Correlates with BMI
The goal of this study was to examine the correlation between shelf space devoted to various categories of food and BMI in a variety of nations. A total of 121 supermarkets in 10 different countries were evaluated by taking linear measurements of shelf space devoted to 8 categories of foods, and assessing whether there was any relationship to mean population BMI. Trends were detected for the following food categories: 1. higher percent shelf space devoted to fresh vegetables, fresh fruit, canned vegetables, and canned fruit were all associated with a lower national BMI; 2. higher percent shelf space devoted to cereals/pastas/grains/bread, junk food and dairy showed a trend to higher national BMI.
