Study Notes

Nutrition

Nutrition is the interaction between an organism and its food.
Nutrients are organic and inorganic substances that contribute to body functions.
Nutrients are divided into six categories: carbohydrates, proteins, fats (lipids), vitamins, minerals, and water.
Not all foods provide all nutrients.
The three key functions of nutrients include providing energy, providing structural material for body tissues, and regulating body processes.

Energy Balance

Energy balance refers to the relationship between energy intake and energy expenditure.
The energy is consumed in the form of calories from carbohydrates, proteins, fat, and alcohol.
A Calorie is a unit of heat energy.
A large calorie (Calorie, kilocalorie [Kcal]) is the amount of heat energy required to raise the temperature of 1 gram of water 15 to 16 degrees Celsius.
In the metric system the energy unit is the kilojoule (kJ). One Calorie equals 4.18 kilojoules.
The amount of energy released by metabolism differs across food types:
- Carbohydrates: 4 Calories/gram (17 kJ)
- Proteins: 4 Calories/gram (17 kJ)
- Fats: 9 Calories/gram (38 kJ)
- Alcohol: 7 Calories/gram (29 kJ)

Body Weight and Body Mass Standards

Ideal body weight (IBW) refers to the weight recommended for optimal health.
Body Mass Index (BMI) is a more reliable indicator of a person's healthy weight.
BMI is calculated by dividing a person's weight in kilograms by their height in meters squared.
The formula for BMI is: Weight (kg) / Height (m)2
Percent body fat is another measure of body mass.
Underwater weighing and dual-energy x-ray absorptiometry (DEXA) are the most accurate methods for measuring body fat percentage, but these methods are time-consuming and expensive.
More practical measures include waist circumference, skinfold testing, and bioelectrical impedance analysis.

Factors Affecting Nutrition

Development: Nutrition needs change significantly across the lifespan.
- Infants and adolescents need more nutrients than older adults.
- Older adults might require fewer calories due to a decrease in metabolic rate and physical activity.
Sex: Nutrient requirements between men and women often differ due to body composition and reproductive functions.
- Men typically have more muscle mass, requiring more calories and protein.
- Women require more iron than men before menopause due to menstruation.
- Pregnant and lactating women have increased caloric and fluid needs.
Ethnicity: Ethnicity can influence dietary preferences, cultural beliefs, and food choices.
Religion: Religious beliefs and practices can affect food choices and dietary restrictions.
Socioeconomic Factors: Access to nutritious foods, finances, and availability of fresh produce contribute to an individual's nutritional status.
Medications: Many medications interfere with nutrient absorption.
Health: Poor health can influence a person's appetite and nutritional status.
Alcohol Consumption: Excessive alcohol consumption can contribute to nutrient deficiencies and other health problems.
Advertising: Food producers attempt to influence consumer preferences through advertising.

Nutritional Variations Throughout the Life Cycle

Infancy and Childhood: Rapid growth requires a diet rich in calories, protein, calcium, and vitamin D.
Adolescence: Adolescents need extra calories, carbohydrates, protein, iron, calcium, and vitamin D.
Young Adulthood: Maintaining bone health requires adequate intake of calcium and vitamin D.
Middle-Aged Adults: Focus on limiting cholesterol and calories. Maintaining adequate protein and calcium intake is important.
Older Adults: Lower metabolic rate and decreased physical activity lead to a need for fewer calories. Social and economic factors can impact nutritional status.

Standards for a Healthy Diet

Dietary Guidelines for Americans: Published every 5 years, these guidelines encourage an overall nutrient-rich and calorie-balanced diet.
- Shift to more plant-based foods.
- Reduce consumption of foods with added sugars and solid fats.
- Engage in regular physical activity.
- Consume foods rich in vitamin D, calcium, potassium, and fiber.
- Keep daily fat intake within 20% to 35% of total calories.
- Consume less than 1,500 mg of sodium per day.
- If you drink alcohol, do so in moderation (one drink per day for women and two drinks per day for men).

Vegetarian Diets

Vegan: A diet that only uses plant foods.
Vegetarian: Individuals who include milk, eggs, or dairy products in their diet, but exclude meat.

Clinical Manifestations

Malnutrition: A state of nutritional deficiency that can lead to various health issues.
Risk Factors: Factors that increase susceptibility to malnutrition include poverty, chronic illness, and substance abuse.
Clinical Signs: Common signs of malnutrition include weight loss, fatigue, and muscle weakness.

Implementing Nutritional Interventions

Nursing Interventions: Nurses play a key role in promoting optimal nutrition by creating a supportive environment, providing assistance with eating, and monitoring food intake.
Special Diets: Diet modifications are often needed for clients with specific illnesses or conditions.
- Examples of special diets include clear liquid diet, full liquid diet, soft diet, and pureed diet.
- Clear liquid diet: Provides fluids and carbohydrates but lacks vitamins and minerals.
- Full liquid diet: Includes liquids and foods that can be liquefied at room temperature.
- Soft diet: Easily chewed and digested. Low in fiber.
- Pureed diet: Food blended into a semisolid consistency.
Diet as Tolerated: Clients with fluctuating appetite, ability to eat, and tolerance for certain foods may receive this order where they eat as tolerated.
