Some evidence suggests a close relationship between diet and mood.
In 2016, researchers found that diets with a high glycemic load may trigger increased symptoms of depression and fatigue.
A diet with a high glycemic load includes many refined carbohydrates, such as those found in soft drinks, cakes, white bread, and biscuits. Vegetables, whole fruit, and whole grains have a lower glycemic load.
If a person suspects they have symptoms of depression, talking to a doctor or mental health professional can help.
