Introduction
Mental health is influenced by various factors such as genetics, environment, lifestyle, and physical health. However, an often-overlooked contributor is nutrition. Just as a balanced diet supports physical well-being, it also plays a crucial role in maintaining mental wellness. The brain, like any other organ, needs essential nutrients to function properly. From regulating mood to reducing the risk of depression and anxiety, nutrition has a direct impact on mental health.
