Sugary Drinks Linked to Increased Anxiety Risk in Teens
A recent study reveals a concerning link between sugary drinks and anxiety among teenagers. Researchers from the U.K. conducted a meta-analysis, evaluating multiple studies from 2000 to 2025, as published in the Journal of Human Nutrition and Dietetics. They looked into how beverages sweetened with sugar, like sodas, energy drinks, and sweetened juices, affect anxiety disorders in adolescents aged 10 to 19.
According to the findings, teens who consume more sugary drinks are about 34% more likely to suffer from anxiety disorders compared to their peers who drink less of these beverages. Out of the nine studies included in the analysis, seven showed a clear connection between high sugary drink intake and anxiety symptoms.
Dr. Chloe Casey, a nutrition lecturer at Bournemouth University and one of the study’s authors, noted that while much attention has been given to the physical health effects of bad diets—like obesity—there has been less focus on how diet impacts mental health. “The mental health implications of diet have been under-explored compared to physical health,” she said.
It’s important to understand that this study does not prove sugary drinks directly cause anxiety. There remains the possibility that teens who are anxious might opt for more sugary beverages as a way to cope. However, Casey highlighted a troubling trend of rising anxiety disorders among adolescents and stressed the importance of identifying lifestyle habits that could help mitigate this issue.
In the United States, about 11% of children between the ages of 3 and 17 were diagnosed with anxiety as of 2022-2023, per the Centers for Disease Control and Prevention. The agency emphasizes that anxiety, behavior disorders, and depression are the most commonly diagnosed mental health issues in children.
Registered dietitian Ilana Muhlstein, who wasn’t involved in the study, pointed out that sugary drinks act like “liquid sugar” in the body. They hit the bloodstream rapidly, causing insulin spikes and leading to crashes in blood sugar, which can mimic anxiety symptoms. She noted that today’s teens seem to be shifting from soda to other sugary drinks like oat milk lattes and sports beverages, which could be just as concerning.
Muhlstein warned that these blood sugar spikes not only affect mood but can also lead to issues like weight gain and poor sleep quality. “What these kids drink hugely affects their physical and emotional state,” she stated.
Nutritionist Serena Poon highlighted that food and beverages provide vital information to the body and brain. “What teens drink regularly affects their energy levels and mood stability,” she explained. She advised that parents encourage their children to hydrate with water or herbal teas and emphasize balanced meals to help manage blood sugar and mood.
Poon concluded that adolescence is a critical time for brain development, and providing balanced nutrition and hydration can support both physical health and emotional well-being.
This study serves as a reminder of the importance of mindful eating and drinking habits, especially during the formative teen years.
