2. Sugar
Sugar causes anxiety as it spikes your blood sugar. Your body increases insulin production and that makes you feel tired.
Fruit juice is just as bad as soda when it comes to adding sugar immediately into your system. Once you lose fruit from fruit juice, you are drinking sugar water.
Sweets, cakes, and other treats might make you feel good while you are eating them, but afterwards, you’ll be dropped and feel anxious afterward. Do yourself a favor and try to avoid sugar.
