Drinking one glass or more of 100% fruit juice each day is associated with weight gain in children and adults, according to a new analysis of 42 previous studies.
The research, published Tuesday in JAMA Pediatrics, found a positive association between drinking 100% fruit juice and BMI — a calculation that takes into account weight and height — among kids. It also found an association between daily consumption of 100% fruit juice with weight gain among adults.
100% fruit juice was defined as fruit juices with no added sugar.
BMI is a shit measure and studies like this are impossible to do well. That does not mean fruit juice is magically sugar-free.
I agree. The message should be; use in moderation. The message in the article and what many people are taking away though is avoid like soda and cigarettes.
BMI is kind of the okay and strongly correlates with health outcomes.
It is not a one size fits all tool, but it is a useful tool in aggregate.
