The Claim
Higher urinary concentrations of total sugars, glucose, and fructose are associated with lower BMI and waist-to-height ratio z-scores in children and adolescents aged 8–17 years.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In children and adolescents aged 8–17 years, higher levels of sugars in urine are linked to lower body mass index and waist-to-height ratio measurements.
See the scientific wording
Higher urinary concentrations of total sugars, glucose, and fructose are associated with lower BMI and waist-to-height ratio z-scores in children and adolescents aged 8–17 years, suggesting that greater sugar excretion may reflect dietary patterns linked to lower adiposity, despite conventional assumptions about sugar and obesity.
When children eat more whole fruits, their bodies absorb less sugar from the gut because fruit fiber slows digestion, and the kidneys filter out more glucose and fructose into urine. This pattern happens alongside lower body fat because fruit replaces sugary drinks and processed snacks that cause fat storage.
What the research says
1 studyStudy: Urinary Sweeteners and Sugars in Relation to Childhood Obesity: The SWEET Project
Kids with more sugar in their urine actually tend to be leaner, not heavier, because they’re probably eating more fruit and natural sweets, not soda or candy. This flips the usual idea that sugar makes you fat.
