The major types of nutrients that can be obtained from food are six essential categories:

• Carbohydrates
• Proteins
• Fats
• Vitamins
• Minerals
• Water

These nutrients are classified into macronutrients (carbohydrates, proteins, fats, and water) which the body needs in large amounts for energy and bodily functions, and micronutrients (vitamins and minerals) which the body needs in smaller amounts for growth, immune function, and metabolism. Each of these nutrients plays a unique and vital role in maintaining health and supporting the body's physiological processes.
