Study Notes

History of Nutrition as a Science

The study of nutrition explores how organisms obtain, process, and utilize nutrients for life, growth, and health
It encompasses nutrient metabolism, health and disease impact, and the relationship between diet, health, and disease prevention

Naturalistic Era (400 BC - 1750 AD)

Hippocrates (460 - 370 BC): Known as the "Father of Medicine," emphasized the importance of food in maintaining health
Galenus (129 - 216 AD): Building on Hippocrates' work, influenced by religious and philosophical beliefs related to food and health
Middle Ages (5th to 15th centuries): Reliance on religious and philosophical beliefs for health knowledge
Renaissance (14th to 17th centuries): Renewed interest in science and the human body

Chemical-Analytical Era (1750 - 1900)

Antoine Lavoisier (1743 - 1794): Considered the "Father of Modern Chemist" and "Father of Nutrition." He conducted experiments that established the fundamental principles of respiration and metabolism
William Prout (1785 - 1850): Classified foods into three groups: carbohydrates, fats, and proteins
Justus von Liebig (1803 - 1873): Emphasized the chemical composition of food and its impact on the body

Biological Era (1900 - 1955)

Casimir Funk (1912): Coined the term "vitamine" (later shortened to vitamin)
Elmer McCollum & Marguerite Davis (1913): Discovered vitamins A and B
Frederick Gowland Hopkins (1929): Demonstrated the necessity of vitamins for health

Cellular or Molecular Era (1955 - 1980)

Advances in Biochemistry and Molecular Biology: Led to a deeper understanding of how nutrients impact cellular functions
Enzyme Function: Understanding how vitamins and minerals act at the cellular level
Hormonal Regulation: Studies on how nutrition affects hormone regulation

Common Nutritional Nursing Diagnoses

Nutritional Deficiencies: Lack of essential nutrients, such as vitamins, minerals, or proteins
Imbalances: Inadequate or excessive intake of specific nutrients
Malnutrition: A state of poor nutrition
Obesity: Excessive body weight, often leading to health problems
Eating Disorders: Disordered eating patterns, such as anorexia nervosa or bulimia nervosa
Food Allergies: Adverse reactions to certain foods

Roles of Nursing in Nutrition Care

Nutritional Assessment:
- Screening and Evaluation: Assessing patients' nutritional status to identify those at risk for malnutrition or deficiencies
- Anthropometric Measurements: Taking measurements such as weight, height, Body Mass Index (BMI), and skinfold thickness to assess nutritional status
Nutritional Education:
- Patient Education: Educating patients about the importance of nutrition, promoting healthy eating habits
- Dietary Counseling: Providing personalized dietary advice, based on the patient's health status, preferences, and needs
Care Planning:
- Developing Care Plans: Collaborating with dietitians and other healthcare professionals to create tailored nutritional plans for individual patients
- Setting Goals: Helping patients establish realistic and achievable nutritional goals
Monitoring and Evaluation:
- Ongoing Monitoring: Tracking changes in patients' nutritional intake and status
- Evaluating Outcomes: Assessing the effectiveness of nutritional interventions
Direct Support:
- Assisting with Feeding: Helping patients with feeding, particularly those unable to feed themselves
- Administering Nutritional Therapies: Administering enteral or parenteral nutrition for patients with difficulty eating
Advocacy:
- Patient Advocacy: Speaking up for patients' nutritional needs within the healthcare team
- Resource Identification: Connecting patients with community resources such as food banks and meal programs

- Interdisciplinary Collaboration: Working closely with dietitians, physicians, and other healthcare professionals
- Communication: Ensuring effective communication within the healthcare team
Documentation:
- Accurate Record-Keeping: Maintaining detailed records of patients' nutritional assessments, care plans, and interventions
- Reporting Changes: Reporting any significant changes in patients' nutritional status promptly
Special Nutritional Care:
- Managing Special Diets: Helping manage and implement special diets, like for diabetes or food allergies
- Nutrition in Chronic Illness: Providing nutritional support and education for management of chronic conditions
