Why are essential nutrients important for the body?

Essential nutrients are critical for maintaining overall health and proper bodily functions. They cannot be produced by the body on its own, which means that they must be obtained through diet. These nutrients include vitamins, minerals, proteins, fats, and carbohydrates, each playing specific roles in processes such as immune function, energy production, and cell repair. Without adequate intake of these essential nutrients, the body may become deficient, leading to various health issues and impaired physiological functions. This highlights the importance of a balanced diet rich in diverse food sources to ensure that all essential nutrients are consumed in appropriate amounts to support health and well-being.
