Clinical nutrition plays a vital role in managing chronic diseases by providing tailored dietary interventions that can improve patients' health outcomes. Nutritionists assess a patient’s nutritional needs and design personalized meal plans to address specific health issues such as diabetes, hypertension, or obesity. Evidence-based dietary guidelines can help prevent disease progression and complications. Additionally, education on healthy food choices and lifestyle modifications enables patients to take an active role in their own health, leading to better adherence and improved quality of life.
