An analysis published in JAMA Pediatrics found a correlation between children’s consumption of 100 percent fruit juice and weight gain. The analysis examined 42 studies investigating the link between fruit juice consumption, body mass index (BMI), and weight gain.
It revealed that consuming 100 percent fruit juice was associated with higher BMIs in children and weight gain in adults. Additionally, the study indicated that children under the age of 11 had a greater BMI compared to older children when analyzing the relationship between fruit juice intake and BMI. The youngest group, aged 8 years or younger, exhibited the most significant increases in BMI according to the study.
According to the study, an 8-ounce serving of pure fruit juice, equivalent to a standard glass, would contribute a larger portion of daily energy for younger children compared to older children. This aligns with the American Academy of Pediatrics’ recommendation that children under 6 years old should consume less than a glass of fruit juice per day.
The analysis specifies that 100 percent fruit juice contains no added sugars. Additionally, the Body Mass Index (BMI) is a widely used health indicator that assesses body fat based on an individual’s height and weight.
The researchers suggested postponing the introduction of 100% fruit juice to young children, monitoring portion sizes, and encouraging the consumption of whole fruits instead. Early exposure to fruit juice was linked to a higher risk of overweight and obesity due to the preference for sweeter foods.
“While the impact on BMI is minimal, even small increases over time can have long-term effects. Thus, restricting fruit juice intake in children is a crucial strategy for promoting healthy weight development,” the study explains.
Additionally, the analysis found a connection between adult consumption of 100% fruit juice and weight gain, likely influenced in part by energy intake.
The researchers concluded that our results affirm the public health recommendation to restrict the intake of 100% fruit juice in order to prevent overweight and obesity.
