For many teens here in Nashville, grabbing a colorful drink from Starbucks after school feels almost like a rite of passage. Between coffee-based Frappuccinos, sweet teas, energy drinks, and sodas, sugary beverages are a part of teen social life. But if you’re parenting a teen who already struggles with anxiety, that reality can get complicated — you want them to fit in, but you also want to protect their well-being.
Teen Anxiety
For decades, experts have warned about sugary drinks and physical health — linking them to concerns like obesity, tooth decay, type 2 diabetes, and heart disease. But now, researchers are taking a closer look at how these drinks may affect mental health, too.
A large systematic review and meta-analysis published in the Journal of Human Nutrition and Dietetics analyzed data from nine surveys conducted between 2000 and 2025. Researchers examined young people’s consumption of sugary beverages — including soda, energy drinks, sweetened juices, flavored milks, and even sweetened coffee and tea drinks — and compared it with measures of mental health.
Their findings were consistent: teens who consumed higher amounts of sugary drinks had 34% higher odds of experiencing anxiety.
A similar 2019 study conducted in China found that adolescents who drank more soft drinks reported higher levels of both depression and anxiety symptoms.
It’s important to pause here with perspective and compassion. The researchers are clear: this data shows a link, not proof of cause and effect. It may be that anxious teens reach for sugary or caffeinated drinks as a coping mechanism. It may also be that blood sugar spikes, caffeine, sleep disruption, or other lifestyle factors play a role. Most likely, it’s complex.
Still, this connection matters — especially as rates of adolescent anxiety continue to rise nationwide.
Last year, beverage recommendations from medical and nutrition experts at Healthy Eating Research encouraged kids and teens to focus on simple hydration: plain water as the primary drink, and avoiding beverages with caffeine, added sugars, or even sugar substitutes. Notably, about one in four teens consumes caffeine daily — something many parents may not realize.
If you already know your teen struggles with anxiety, this isn’t about blame or banning every treat. It’s about gentle awareness.
Start By:
-
Talking openly about how certain drinks make them feel — energized, jittery, calm, or more on edge.
-
Noticing patterns between late-day caffeine and sleep struggles.
-
Gradually swapping one sugary drink a day for water, sparkling water, or a favorite reusable water bottle they actually like carrying.
-
Modeling balanced choices yourself.
Teens don’t need perfection. They need to know that small changes are doable.
Helping your teen understand how what they drink may affect how they feel can be one practical, manageable step in supporting their mental health.
And when it comes to managing anxiety, every small, steady step counts.
