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.
No sugar added also means they can pour in concentrated pear juice as an ingredient and earn the label while having just the same amount of sugar as the same volume of soda.
And believe it or not, fructose is even harder for the body to process than sucrose and can lead to fatty liver issues.
