Nutrition plays a crucial role in mood stability. Foods rich in complex carbohydrates, like whole grains, facilitate the gradual release of serotonin, which is a neurotransmitter linked to feelings of well-being. Meanwhile, deficiencies in nutrients such as omega-3 fatty acids and vitamins can lead to irritability or mood swings. A balanced intake of proteins and healthy fats also supports cognitive function, influencing emotional regulation. Thus, maintaining proper nutrition can contribute to a more stable and positive mood over time.
