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.
Edit: I learned to read. It’s because of the no added sugar.
Added sugar is a problem when it’s added to things that don’t need it. The best way to mitigate this isn’t with a sugar tax, but to tax per calorie in the finished food for any amount of added sugar.
