It seems like, as a group, the type of people who would drink large amounts of sugary soda would be less likely to make healthy behavioral choices in other aspects of their life, compared to people who drink fruit juice or diet soda. This could also explain the disparity between soda and non-carbonated sugar-sweetened beverages&lt;p&gt;This study doesn&amp;#x27;t seem to show that soda ages you (as the article states), but instead that sugary soda consumption indicates a tendency towards other activities&amp;#x2F;habits that may prematurely age you.</text><parent_chain><item><author>mikeyouse</author><text>The key results from the paper:&lt;p&gt;&lt;pre&gt;&lt;code&gt;    After adjustment for sociodemographic and health-related
