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.
A glass of fruit juice still has calories in it. I would imagine that if you control for everything else that it’s still a couple of hundred extra calories that one kid is taking in that some other kid isn’t.
Not only that, it’s also almost pure carbohydrates
