Define 'nutritional therapy.'

Nutritional therapy refers specifically to the use of nutrition interventions as a means of managing health conditions. This encompasses a broad range of practices where dietary modifications and tailored nutrition plans are developed to address specific health concerns. By focusing on individual nutritional needs, practitioners can help patients improve their overall health, manage chronic diseases, and optimize bodily functions. Nutritional therapy is evidence-based and typically involves the assessment of a person's dietary habits, nutrient deficiencies, and medical history to create a personalized nutrition strategy aimed at achieving better health outcomes.

The other options do not accurately define nutritional therapy as they focus on different aspects of health management. Exercise, while vital for overall wellness, is not the primary focus of nutritional therapy. The prescription of medication relates more to pharmacological interventions rather than dietary ones. Similarly, emotional support through balanced diets is a component of holistic health but does not encompass the comprehensive approach that nutritional therapy entails, which is primarily centered around dietary practices and interventions.
