Drinking a glass or more of 100% fruit juice daily is associated with a small weight gain in children and adults, according to a new analysis.
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.
It also raises the question: If fruit is good for you and recommended as part of a healthy diet, why can 100% fruit juice lead to weight gain? The authors point to 'liquid calories' as a possible factor. 'A potential mechanism linking 100% fruit juice to weight gain is the consumption of liquid calories, which has been shown to result in greater weight gain compared with the ingestion of solid calories,' they note.
