3. Caffeinated drinks
Although you may first consider coffee, which actually offers a range of key health benefits, caffeine is a stimulant and when consumed in high enough doses, you may increase stress-related symptoms of anxiety. In terms of their overall effect on your health, beverages such as soda and energy drinks are highly damaging.
Not only do they expose you to high levels of sugar, but when consuming too much caffeine, you can increase cortisol levels while influencing neurotransmitter balance. Within one study, published in Depression and Anxiety, energy drink consumption was significantly correlated with increased anxiety in young male adults.
