High glycemic index foods and added sugar

High glycemic index (GI) foods cause a quick rise in blood sugar levels. These include sweets, processed carbs like white bread, and foods with a lot of added sugar.

Significant spikes and decreases in blood sugar are brought on by high GI foods. Your body is then forced to release hormones like growth hormone, cortisol, and adrenaline, which can cause symptoms like anxiety and irritability. According to studies, having low blood sugar can make it more difficult to fall asleep. On the other side, having high blood sugar after a meal with a high glycemic index may make you feel tired at first, but the changes in hormones that followed, particularly insulin, may make you wake up later in the night. High glycemic diets also cause inflammatory reactions in the body and imbalances in the beneficial bacteria in the gut, which may impact sleep.
