Explanation

Good nutrition is essential for holistic well-being, as defined by the World Health Organization (WHO), which includes complete physical, mental, and social well-being.
Physically, a balanced diet provides energy, supports growth and tissue repair, and strengthens the immune system, preventing both deficiency diseases and chronic illnesses.
Mentally, the brain requires a constant supply of nutrients to function correctly. Good nutrition supports cognitive processes, memory, mood regulation, and overall psychological well-being.
The interconnectedness is clear: poor physical health can lead to stress and depression (mental health issues), and poor mental health can affect appetite and physical ability.

Option A: This is incorrect because it ignores the significant impact of nutrition on brain function, chemistry, mood, and cognitive abilities.
Option B: This is incorrect as the physical body is entirely dependent on nutrients for energy, cell maintenance, survival, and all physiological processes.
Option C: This is too narrow. While nutrition is a key factor in managing body weight, its role extends far beyond that to encompass all aspects of physical and mental functioning.

Visual 1: Infographic - A diagram showing a human silhouette divided into 'Physical Health' (with icons for heart, bones, muscles) and 'Mental Health' (with an icon for the brain). Arrows from various food groups (fruits, vegetables, grains, proteins) point to both sides, with labels like 'Energy', 'Repair', 'Cognition', and 'Mood'.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Holistic benefits of good nutrition as background academic context rather than a clinical decision trigger.
Nurses play a crucial role in patient education, explaining that a balanced diet is vital not just for physical recovery from illness but also for improving mood and cognitive function during hospitalization.
In community health, nurses assess nutritional status to prevent conditions like iron-deficiency anemia, which causes physical fatigue and also impairs a child's ability to concentrate in school.
What if? A patient recovering from surgery reports feeling depressed and has a poor appetite. A nurse should recognize this link and advocate for a nutritional consult, suggesting nutrient-dense foods that support both tissue healing (physical) and mood improvement (e.g., foods rich in omega-3s and B vitamins).

How to Approach the Question

Step 1: Analyze the question to identify the core concept: the scope of benefits from 'good nutrition'.
Step 2: Evaluate the scope of each option. The words 'Only' in options A, B, and C are highly restrictive and often indicate an incorrect choice in questions about broad biological concepts.
Step 3: Consider the holistic nature of health. Health is rarely compartmentalized; systems within the body are interconnected. What affects one part often affects others.
Step 4: Recall the basic functions of nutrients. They provide fuel and building blocks for the entire body (physical) and the brain (mental).
Step 5: Select the option that reflects this integrated and comprehensive view of health, which is 'Both physical and mental health'.
