Recent studies highlight an alarming correlation between sugary drinks and anxiety among teens. This research underscores the potential impact of dietary choices on mental health, urging a closer examination of adolescents’ beverage consumption habits.
The Impact of Sugary Drinks on Adolescent Anxiety
An excess of sugary drinks can specifically lead to a higher risk of anxiety among teens, a new study shows.
In a meta-analysis published in the Journal of Human Nutrition and Dietetics, U.K. researchers reviewed various studies from 2000 to 2025.
They explored the link between drinking sugar-sweetened beverages — like sodas, energy drinks, sweetened juices, teas, and coffee — and anxiety disorders in adolescents aged 10 to 19 years.

Teens who consumed greater amounts of sugary drinks exhibited roughly a 34% higher risk of developing an anxiety disorder compared to those who consumed less.
Seven out of the nine studies analyzed by the researchers indicated a significant positive association between sugary drink intake and anxiety symptoms.
“With increasing concern about adolescent nutrition, most public health initiatives have emphasized the physical consequences of poor dietary habits, such as obesity and type 2 diabetes,” study co-author Dr. Chloe Casey, lecturer in nutrition at Bournemouth University in the U.K., noted in a press release.

“However, the mental health implications of diet have been under-explored by comparison, particularly for drinks that are energy-dense but low in nutrients.”
The study was based on observational data, which does not prove that drinking sugary beverages directly causes anxiety. There is also no clear indication of whether sugary drinks lead to anxiety or if anxious teens are more likely to consume them.
“While we may not be able to confirm at this stage what the direct cause is, this study has identified an unhealthy connection between consumption of sugary drinks and anxiety disorders in young people,” Casey remarked.
“Anxiety disorders in adolescence have risen sharply in recent years, so it is important to identify lifestyle habits that can be changed to reduce the risk of this trend continuing.”

According to the Centers for Disease Control and Prevention, approximately 11% of American children between the ages of 3 and 17 were diagnosed with anxiety between 2022 and 2023.
“Anxiety problems, behavior disorders, and depression are the most commonly diagnosed mental disorders in children,” states the agency’s website.
“While it’s important to note that this study is correlation, not causation, I have no doubt that a better-designed study would show the same results,” Los Angeles-based registered dietitian nutritionist Ilana Muhlstein shared with Fox News Digital.
“Soda, aka liquid sugar — with no fiber, protein, or fat to slow absorption — floods the bloodstream faster than almost any other type of food or drink,” commented Muhlstein, who was not involved in the study.

“The pancreas scrambles to respond, insulin spikes, blood sugar crashes, and you are left in a dopamine deficit state that looks and feels just like anxiety,” she elaborated. “The sharper the spike, the deeper the crash.”
In her own practice, Muhlstein observed that teens are consuming less soda and more oat milk lattes, coffee drinks “loaded” with syrup, slushies, and sports drinks.
Excessive blood sugar spikes can also impact weight, acne, sleep quality, and emotional regulation, she noted, regardless of caffeine levels.
“What these children drink significantly influences their physical and emotional state, and caffeine on top of unstable blood sugar only exacerbates the issue,” Muhlstein warned.

Serena Poon, a certified nutritionist and founder of Wholistic Lifestyle Medicine in Los Angeles, pointed out that food and beverages “are more than just fuel.”
“They provide information to the body and brain,” the expert, who also did not participate in the research, stated to Fox News Digital. “What teens drink regularly can influence energy levels, mood stability, and even how the nervous system responds to stress.”
“Highly sweetened drinks can create quick energy spikes followed by drops, and when caffeine is included, it can heighten stress responses in the body,” she added.

Poon recommended that parents encourage their children to limit sugary drinks and opt for water, herbal teas, or sparkling water to maintain more stable energy levels.
It’s also advisable to ensure that meals are balanced with fiber, healthy fats, and proteins to help stabilize blood sugar, which can impact mood and focus.
“Adolescence is a critical period for brain development, so supporting teens with balanced nutrition, stable energy levels, and adequate hydration may promote both physical and emotional well-being,” Poon added.
Fox News Digital reached out to the American Beverage Association and Bournemouth University for comment.
