Therapeutic Diets

• Therapeutic diets are meal plans designed to control the intake of specific foods or nutrients.
• These diets are prescribed by a physician and planned by a dietitian to manage medical conditions.
• They are typically modifications of regular diets.
• The goal of nutritional therapy is to provide patients with the necessary nutrients in the correct quantities, in a form that is acceptable and usable.
• Nutritional needs vary based on age, sex, environment, emotional and physical stress levels.

Therapeutic Nutrition

• Personalized evidence-based eating plans to manage chronic conditions
• Aims to reduce or reverse chronic conditions and symptoms
• Directly impacts the cause of the disease
• Enhances the body's natural defenses against illness
• Affects neurohumoral regulation – balance of hormones and nerves
• Aids in body recovery
• Plays a key role in managing metabolic diseases

Therapeutic Nutrition Principles

• Tailored to individual disease stages, severity, and infection levels.
• Considers morphological changes in organs and the entire body.
• Emphasizes individual patient responses to food.
• Prioritizes accessible food options for patients.

Nutritional Status Assessment

• Determining the patient's nutritional status is a crucial first step in nutritional treatment.
• This involves a comprehensive analysis of the patient's overall health and dietary intake.
• An assessment includes gathering a thorough nutritional history to understand past dietary habits and potential deficiencies.
• It also involves a careful examination for signs and symptoms that might indicate specific nutritional deficiencies.
• Additionally, evaluating the body's current energy reserves is essential, as this provides insight into the patient's overall nutritional state.

Nutritional Deficiency Symptoms

• Tongue inflammation: A potential sign of nutritional deficiency.
• Reduced skin fold thickness: Indicates a lack of essential nutrients, especially protein and hydration.
• Edema: Swelling in various body parts, often linked to deficiencies affecting fluid balance.
• Wounds taking a long time to heal: Suggests a lack of nutrients vital for tissue repair.
• Ulcers caused by lying down: A symptom that can point to nutrient deficiencies impacting circulatory health.
• Hair loss: A common indicator of deficiencies in iron, zinc, and other essential nutrients.
• Amyotrophic Lateral Sclerosis (ALS): While not directly caused by a nutritional deficiency, nutritional management plays a crucial role in the care of ALS patients.
• Myasthenia: A neuromuscular disorder not directly caused by nutrient deficiency, but dietary interventions can support muscle health.

Assessing Body Energy Reserves

• Lipid reserves: A significant source of energy storage in the body.
• Skin fold thickness measurement: A common method to assess body fat percentage, as approximately 50% of body fat is located under the skin.
• Measurement sites: Triceps (back of the upper arm), below the shoulder blades, abdomen (abs), and hips.
• Reference values: For triceps, a measurement of 12.5mm for males and 16.5mm for females is considered a standard.
• Reduced lipid reserves: Indicates a depletion of stored energy, potentially suggesting a need for dietary adjustments or increased energy intake.

Hospital Diets: Food Practices and Nutrition

• Hospital food practices vary widely.
• Therapeutic diets (e.g., low salt, gluten-free, texture-modified) can decrease energy delivery, increasing the risk of malnutrition.
• Hospital diets should be tailored to individual patient needs, considering age (65 years and older), disease status (acute, chronic), malnutrition risk, and metabolic stress.
• Scientifically-based recommendations should guide the composition of hospital diets.
• Local food habits and food patterns are important considerations.
• Therapeutic diets are prescribed based on the specific disease or needs of each patient.

Benefits of Proper Nutrition in Chronic Kidney Disease

• Prevention and treatment of malnutrition: Malnutrition is a common complication of chronic kidney disease (CKD) and can worsen symptoms and outcomes. Proper nutrition helps prevent or treat malnutrition by ensuring adequate intake of essential nutrients.

• Correction of metabolic disorders: CKD often leads to metabolic disorders such as electrolyte imbalances, anemia, and bone disease. A tailored diet can help correct these imbalances and improve overall health.

• Slow progression of chronic kidney disease: Proper nutrition can help slow the progression of CKD by reducing inflammation, oxidative stress, and other factors that contribute to kidney damage.

• Improved quality of life: A healthy diet can help patients with CKD feel better, have more energy, and enjoy a higher quality of life.

Protein Intake Recommendations

• Normal Diet: Daily protein intake is recommended to be between 0.8 to 1.0 grams per kilogram of body weight.
• High-Protein Diet: Involves consuming more than 1.3 grams of protein per kilogram of body weight daily.

Protein Intake in Chronic Kidney Disease

• Reduced Protein Intake: Individuals with chronic kidney disease should limit their protein intake to 0.6 grams per kilogram of body weight daily for animal protein or 0.7 grams per kilogram of body weight daily for vegetable protein.
• Very Low Protein Intake: In severe cases of chronic kidney disease, protein intake may be further restricted to 0.3 grams per kilogram of body weight daily.

Protein Quality

• Protein is essential for various bodily functions.
• Meat, fish, poultry, and egg whites are excellent sources of protein.
• A protein-reduced diet typically involves consuming 0.6 grams of protein per kilogram of body weight.
• Legumes and cereals can be valuable sources of protein for vegetarians.
• Vegetarians may need to carefully plan their diets to ensure adequate protein intake.

Dietary Considerations

• The protein content of food varies depending on the type of food.
• A balanced diet should include a variety of foods to provide all necessary nutrients.
• A complete diet should contain all essential nutrients, including protein, carbohydrates, fats, vitamins, and minerals.
• A comprehensive diet addresses individual needs and considers factors such as age, activity level, and health status.
• A suitable diet for each disease should be tailored to the specific needs of the patient.

Dietary Management

• The duration of an unbalanced diet should be carefully considered.
• Prescribing principles of eating for patients with special therapies is crucial.
• Coordination between nutrition, antibiotics, and therapy is essential for optimal patient care.
• The appropriate diet for an individual's level of activity is a critical factor in maintaining health and well-being.

Food Selection Principles

• Mechanical Impact: Choose foods that minimize mechanical stress on the digestive system.
• Fine Grinding: Finely ground foods are easier to digest and absorb.
• Fiber Reduction: Reduce fiber content in food to ease digestion.
• Pectin Increase: Increase soluble pectin levels in food to soften it.
• Chemical Processing: Avoid excessive chemical effects during food processing.

ESPEN Guideline - Hospital Nutrition Recommendation 1

• Healthcare facilities should have a visible list of available diets for patients and staff.
• This list helps ensure that food is adapted to individual patient needs and care plans.
• Patients should be able to choose from multiple menu options.

Hospital Food Recommendations

• Hospitals, rehabilitation centers, and nursing homes should use high-quality, sustainable food ingredients.
• Food waste should be minimized in these institutions.
• Diets based on food restriction without medical evidence should be avoided.
• Diets, such as "anticancer starvation", can increase the risk of malnutrition.

Hospital Nutrition Recommendations

• Hospital nutrition should be reviewed regularly for all patients, ideally every 3 to 5 days.
• This review should consider the patient's disease progression, their oral intake, and their acceptance of the diet.
• If dietary modifications are ineffective in meeting the patient's energy and protein needs, medical nutrition therapy should be provided, tailored to the stage of the disease.
• Hospitalized patients at moderate to high nutritional risk, or those who are malnourished, should receive a protein and energy-enriched diet.
