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.
Grapefruit juice is an exception to this
Make sure to check with your doctor if you’re on any meds! Grapefruit juice can cause you to absorb more of your medication and can cause overdoses.
The most common drug it messes with is caffeine. Even a little grapefruit juice will make the effects of caffeine far more pronounced.
