Study Notes

Nutrition Learning Outcomes

Identify essential nutrients and their dietary sources.
Determine factors that influence nutrition.
Identify patients suitable for modified diets.
List foods that are restricted or supplemented for patients on modified diets.

Introduction to Nutrition

Nutrition is the interaction between a person and the food they consume.
Nutrients, organic and inorganic, are needed for bodily functions.
A balanced diet includes water, carbohydrates, proteins, fats, vitamins, and minerals.
Nutrients provide energy, build tissues, and regulate bodily processes.
Macronutrients (carbohydrates, fats, proteins, water, vitamins, and minerals) are needed in larger amounts; micronutrients are needed in smaller quantities.

Essential Body Nutrients

Carbohydrates: Monosaccharides (glucose, fructose, galactose), disaccharides (sucrose, lactose, maltose), and polysaccharides (starch, dextrin, glycogen, cellulose, hemicellulose).
Fats: Polyunsaturated (linoleic acid, linolenic acid, arachidonic acid).
Proteins: Amino acids (phenylalanine, lysine, isoleucine, leucine, methionine, valine, tryptophan, threonine, histidine).
Vitamins: Fat-soluble (vitamins A, D, E, K) and water-soluble (vitamins B and C).
Minerals: Calcium, chloride, iron, magnesium, phosphorus, potassium, sodium, sulfur.

Factors Affecting Nutrition

Gender
Ethnicity/culture
Beliefs about food

Normal and Therapeutic Nutrition

Normal nutrition is based on recommended daily allowances for health maintenance.
Therapeutic diets modify nutrient intake to address specific health conditions (excess or deficiency).
Diets may alter minerals, vitamins, proteins, carbohydrates, fats, fluids, and consistency to meet patient needs.

Routes of Feeding

Enteral feeding: Used when patients cannot or will not eat, or require supplemental nutrition (e.g., following burn injury, trauma, or Gl tract impairment).
Feeding methods can be through nasogastric or small-bore tubes, or gastrostomy or jejunostomy tubes.
Enteral feeding is generally preferred over parenteral feeding due to safety, cost-effectiveness, and fewer complications.
Parenteral nutrition (PN): Intravenous nutrition used when patients cannot meet nutritional needs orally or through enteral routes. This is also known as Total Parenteral Nutrition (TPN).

Modified Therapeutic Diets

These diets are customized for specific conditions, surgeries, or examinations.
Diets are altered based on texture, caloric content, specific nutrients, seasonings, and consistency.

Types of Modified Diets

Bland diet: To minimize gastric irritation.
Soft diet: For individuals with difficulty chewing or swallowing.
Pureed diet: Foods are blended to a soft consistency.
Blenderized liquid diet: For those who cannot chew or swallow solid foods.
Clear liquid diet: Provides fluids and minimal solids to allow the digestive system to rest.
Full liquid diet: Includes liquids and easily consumed foods that turn liquid at body temperature.

Modifications for Specific Diseases

Modifications for specific disease processes (e.g., diabetes mellitus, cardiac issues, renal insufficiency) may involve specific nutrient restrictions or additions.
