5. Causes Anxiety and Depression
A sugary diet is also linked to increased risk of anxiety, irritability, mood swings and even depression.
In order to function properly, the brain needs a steady supply of chemicals like glucose and insulin. However, when your brain gets an excess supply of these chemicals due to high sugar intake, it leads to restlessness and anxiety.
High sugar intake can even trick your brain into alcohol and drug addiction. Sugar releases a neurotransmitter called dopamine in the brain, which increase the affinity toward addictive substances like alcohol and different drugs.
A 2015 study published in the American Journal of Clinical Nutrition suggests that high glycemic index diets may be a risk factor for depression in postmenopausal women.
