Ultra-processed foods and added sugars, the content of drinks marketed to children, and cannabis use in first episode psychosis
March was a busy month here at BMJ Open, with many new papers entering the Top 10 Most Read. In at number one this month is a popular paper which was press released and saw a lot of activity on Twitter: a cross-sectional study investigating the contribution of ultra-processed foods to the intake of added sugars in the USA. Boulton et al enter the list at number two with a much discussed survey of fruit juices to determine the sugar content of drinks marketed to children, which made national news, and Brown et al review the effectiveness of community pharmacy-delivered interventions for alcohol reduction, smoking cessation and weight management at number five. Investigating the association of cannabis use with hospital admission and antipsychotic treatment failure in patients with first episode psychosis, Patel et al come in at number five. Finally, at number nine we have an interesting analysis of systematic reviews by Elia et al which asks how authors of systematic reviews deal with research malpractice and misconduct in original studies.
