Verified step by step guidance1
Step 1: Understand the concept of macronutrients. Macronutrients are nutrients required in large amounts by the body to provide energy and support essential physiological functions. They include carbohydrates, proteins, and fats.
Step 2: Differentiate macronutrients from micronutrients. Micronutrients, such as vitamins and minerals, are required in smaller amounts and do not provide energy but are essential for various biochemical processes.
Step 3: Analyze the options provided. Identify which options include macronutrients (carbohydrates, proteins, and fats) and exclude micronutrients (vitamins, minerals, and water).
Step 4: Eliminate incorrect options. For example, 'Vitamins, minerals, and water' are micronutrients, not macronutrients. Similarly, 'Carbohydrates, nucleic acids, and lipids' includes nucleic acids, which are not considered macronutrients.
Step 5: Select the correct answer. The correct list of macronutrients essential in human nutrition is 'Carbohydrates, proteins, and fats.'
