The term "vital nutrients" refers to essential nutrients that are necessary for maintaining good health and proper functioning of our bodies. These nutrients include macronutrients such as carbohydrates, proteins, and fats, which provide energy and building blocks for the body's cells; micronutrients like vitamins and minerals that play crucial roles in various metabolic processes; and dietary fiber, which aids digestion and helps maintain healthy gut flora. Adequate intake of these vital nutrients is necessary for growth, development, repair, and maintenance of our bodies, as well as prevention of chronic diseases such as heart disease, obesity, diabetes, and certain cancers.
