Daily Consumption of 100% Fruit Juice Linked to Weight Gain in Children and Adults

New study supports public health guidance to limit fruit juice intake, citing 'liquid calories' and lack of dietary fiber as potential factors for weight gain.

Drinking one or more glasses of 100% fruit juice daily is associated with weight gain in children and adults, according to a new analysis of 42 previous studies.
Younger children, those under 11 years old, showed a greater BMI gain per every 8-oz additional serving per day of 100% fruit juice than older children.
The study suggests that the weight gain may be due to the consumption of 'liquid calories', which results in greater weight gain compared to the ingestion of solid calories.
100% fruit juice contains less dietary fiber compared to whole fruit, leading to rapid absorption of fructose in the liver and decreased satiety.
The findings support public health guidance to limit consumption of 100% fruit juice to prevent overweight and obesity.
