  • A 2026 meta-analysis found a 34% higher odds of anxiety disorders in adolescents with high sugar-sweetened beverage intake
  • Seven out of nine studies reviewed reported a positive association between sugary drink consumption and anxiety symptoms
  • Over 60% of youth in the United States consume a sugar-sweetened beverage daily

Recent research has examined the relationship between sugar-sweetened beverage intake and anxiety disorders among adolescents, highlighting a potential association based on observational data.

A systematic review and meta-analysis published in February 2026 in the Journal of Human Nutrition and Dietetics reported that adolescents who consumed higher amounts of sugary drinks had 34% greater odds of experiencing anxiety disorders compared to those with lower consumption.

The analysis included nine observational studies, and seven of these studies identified a statistically significant positive link between sugar-sweetened beverage consumption and anxiety symptoms or disorders in adolescents.

Researchers stated that the evidence is based on observational studies, which do not establish a direct cause-and-effect relationship. They noted that other factors, such as reverse causation or confounding variables, may also influence the observed association.

What the numbers show

  • Meta-analysis published on February 10, 2026
  • Odds ratio for anxiety disorders was 1.34 (95% CI: 1.14-1.59) for high sugary drink intake
  • Seven out of nine observational studies reported a statistically significant association
  • More than 60% of U.S. youth consume a sugar-sweetened beverage daily

According to Healthline, the study authors described the observed link as an "unhealthy connection" rather than definitive proof of causation. They emphasized that further research is needed to clarify the nature of this association.

Experts cited by Healthline explained that sugar-sweetened beverages are considered "empty-calorie" sources, which can cause fluctuations in blood sugar levels. These blood sugar changes may contribute to the worsening of anxiety symptoms in some individuals.

In the United States, data reported by the Centers for Disease Control and Prevention indicated that more than 60% of youth consume at least one sugar-sweetened beverage each day, reflecting the widespread nature of this dietary habit among adolescents.

While the findings suggest a connection between sugary drink intake and anxiety symptoms, the researchers and experts involved in the studies consistently stated that the evidence does not confirm a direct causal relationship. They recommended further investigation to better understand the potential impact of sugar-sweetened beverages on adolescent mental health.
