Dietary Therapy
Overview
Dietary therapy refers to a meal regimen that adjusts the diet according to an individual's health status, disease, or goals. It goes beyond simple dieting, aiming for nutritional balance, disease prevention, and treatment. Modern medicine has proven that diet plays a crucial role in managing chronic diseases and promoting health.

Definition and History of Dietary Therapy
Dietary therapy has been considered part of medicine since ancient times. Hippocrates said, "Let food be thy medicine," and in Eastern traditional medicine, dietary therapy has been used as an important treatment method. In modern times, with the development of nutrition science and medicine, diet has gained specific scientific evidence for disease prevention and treatment.
Types of Dietary Therapy
1. Therapeutic Diet: A diet designed to manage specific diseases. Examples include low-sugar diets for diabetes patients, low-sodium diets for hypertension patients, and low-protein diets for kidney disease patients.
2. Preventive Diet: A diet for maintaining health and preventing diseases, including the Mediterranean diet for cardiovascular disease prevention and diets focused on antioxidant-rich foods.
3. Weight Management Diet: Low-calorie diets, ketogenic diets, and intermittent fasting for improving obesity or overweight.
4. Functional Diet: A diet that emphasizes specific health functions, such as probiotics, omega-3 fatty acids, and dietary fiber.
Components of Dietary Therapy
- Carbohydrates: As an energy source, complex carbohydrates (whole grains, vegetables) are recommended.
- Protein: Essential for muscle maintenance and immune function; a balance of animal and plant proteins is important.
- Fats: Unsaturated fatty acids (olive oil, nuts) are beneficial for health, while saturated fats and trans fats are limited.
- Vitamins and Minerals: Needed for antioxidant activity, bone health, nerve function, etc.
- Dietary Fiber: Helps with gut health, blood sugar control, and cholesterol reduction.
- Water: Essential for metabolism and detoxification.
Application Areas of Dietary Therapy
- Diabetes Management: Emphasizes low-glycemic index foods and dietary fiber for blood sugar control.
- Cardiovascular Disease: Low-sodium, low-fat, high-fiber diets are recommended.
- Digestive Diseases: Low-FODMAP diet for irritable bowel syndrome, and non-irritating diet for gastritis.
- Cancer Prevention: Diets rich in antioxidants and dietary fiber are recommended.
- Allergies: Diets that eliminate specific food allergens are necessary.
Scientific Basis of Dietary Therapy
Recent studies emphasize the impact of diet on the gut microbiome. Diets rich in dietary fiber increase beneficial bacteria, while processed foods increase harmful bacteria. Additionally, evidence is accumulating that dietary patterns directly affect inflammatory responses, insulin resistance, and cardiovascular health.
Latest Trends
As of 2024-2025, the following trends are gaining attention in the field of dietary therapy:
- Personalized Diet: Personalized dietary prescriptions based on genetic analysis, gut microbiome testing, and metabolomics are becoming more widespread.
- Rise of Plant-Based Diets: Plant-based diets (vegan, vegetarian) considering environment and health are becoming popular, and the plant-based protein alternative food market is growing rapidly.
- Intermittent Fasting: Studies continue to show that time-restricted eating (16:8, 5:2) is effective for weight loss and metabolic health.
- Functional Foods: Foods fortified with probiotics, prebiotics, polyphenols, and omega-3 are gaining popularity.
- Digital Health and Diet: Diet tracking via mobile apps and wearable devices, and AI-based diet recommendation services are advancing.
- Sustainable Diet: Dietary choices considering environmental impact (local food, low-carbon diet) are becoming important.
