Essential nutrients are fundamental components of a healthy diet, providing the body with necessary elements for growth, development, and overall well-being. These nutrients are classified as essential because the human body cannot synthesize them independently, requiring their acquisition through dietary sources or supplementation. Essential nutrients are categorized into two main groups: macronutrients and micronutrients.
Macronutrients consist of carbohydrates, proteins, and fats, which supply energy and support various physiological functions. Micronutrients encompass vitamins and minerals, which are crucial for maintaining optimal health and preventing various diseases. Consuming a balanced diet that incorporates all essential nutrients in appropriate proportions is vital for ensuring optimal health and well-being.
