About The Study: This systematic review and meta-analysis of 42 eligible studies, including 17 among children (n = 45,851) and 25 among adults (n = 268,095), found a positive association between intake of 100% fruit juice and weight gain in children. Analysis of cohort studies in adults found a significant positive association among studies unadjusted for total energy, suggesting potential mediation by calories; an analysis of trials in adults found no significant association between 100% fruit juice consumption and body weight. The findings support guidance to limit consumption of fruit juice to prevent the intake of excess calories and weight gain.
