Standard Hospital Diet: Nutritional Composition and Clinical Rationale

General (Routine) Diet Specifications

The "Regular" or "House" diet is designed to meet the nutritional needs of the average hospitalized adult without therapeutic restrictions. Values are per day:

Nutrient	Target Range	Clinical Notes
Calories	2,000–2,500 kcal	Adjusted for age, sex, BMI, activity, stress factor (1.2–1.5).
Protein	75–100 g (1.0–1.2 g/kg IBW)	Supports wound healing, immune function, nitrogen balance.
Fat	30% of kcal (≤10% saturated)	Emphasize MUFA/PUFA; limit trans fats.
Carbohydrate	45–55% of kcal	Complex carbs, fiber 25–30g; consistent CHO for glycemic control.
Sodium	≤2,300 mg (often 1,800–2,000 mg)	Aligns with AHA/ADA; lower for HF, CKD, HTN.
Potassium	3,500–4,700 mg	From fruits/vegetables; restrict in ESRD/hyperkalemia.
Cholesterol	<300 mg (per prior guidelines); current focus on saturated fat	Dietary cholesterol less impactful than saturated fat for most.
Fluids	2,000–2,500 mL	Includes beverages, soups, gelatin; adjust for losses/restrictions.

Service Delivery

• Meal Patterns: 3 meals + 2–3 snacks (HS snack for nocturnal hypoglycemia prevention).
• Texture Modifications: Regular → Mechanical Soft → Pureed → Liquid (as ordered).
• Therapeutic Overlays: Cardiac, Renal, Diabetic, Dysphagia, Allergy – modify base diet.

Monitoring

Dietitians assess intake (calorie counts), weight trends, labs (prealbumin, BUN, electrolytes), and wound status. Adjustments made within 24–48h.

The general diet is the foundation; individualization is the standard of care.
