Study Notes

Introduction to Nutrition Across the Lifespan

Growth: Increase in size and mass of an organism.
Development: Process of an organism maturing and becoming more complex.
Impact on growth and development: Nutrition plays a crucial role in the development and wellbeing of individuals across their lifespan.
Impact on disease prevention: Proper nutrition helps prevent chronic diseases and promotes optimal health.

Nutrition in Infancy

Full-Term infant: An infant born between 37 and 42 weeks of gestation.
Physical characteristics of a full-term infant:
- Normal weight: 3.5 kg (normal range: 2.7–4.6 kg).
- Normal length: 50 cm.
- Normal head circumference: 35 cm.
- Disproportionate head size.
- Bowed legs.
- Overall body fat.
- 75% body weight at birth is water.
Physiological characteristics:
- Normal heart rate: 110 to 160 beats/minute.
- Normal respiratory rate: 30–50 breaths/minute.
- Normal body temperature: 36.5 to 37.4°C (axillary).
Primary reflexes: Important for neurological development.
- Rooting reflex: Seeking nipple when cheek is touched.
- Sucking reflex: Creating negative pressure for feeding.
- Moro reflex: Startle response with arm extension.
- Palmar grasp reflex: Grasping objects placed in palm.
- Plantar grasp reflex: Curling of toes when foot is stroked.
- Stepping reflex: Walking movements when feet touch a surface.
- Placing reflex: Lifting foot when the top is touched.
- Asymmetric Tonic Neck reflex: Head turning resulting in arm stretching.

Feeding Practices

Breastfeeding
- Optimal infant nutrition source: Tailored composition to meet infant needs.
- Prolactin: The main hormone responsible for milk production.
- Lactation: Period of milk production by the mother’s mammary gland to feed her infant.
- Recommended for the first 6 months of life.
- Continued breastfeeding with complementary foods up to 2 years or longer.
- Cup Feeding: Safe alternative to breastfeeding.
Benefits of breastfeeding:
- Nutritional adequacy.
- Protective antibodies: Provide immunity against infection.
- Bonding and attachment between mother and infant.
- Lower risk of allergies.
- Antibacterial properties.

Formula Feeding

Breast milk substitute: Made from dried milk powder.
Composition: Cow's milk base, vitamins, minerals, and other nutrients.
Types of infant formulas:
- Milk-based Formulas: Standard options for most infants.
- Soy-based Formulas: For lactose intolerance or allergies.
- Specialty Formulas: For specific medical conditions.
Key differences between formula and breast milk:
- Antibody content: Breast milk contains antibodies that provide immune protection.
- Nutritional composition: Breast milk is more readily digestible and contains specific nutrients tailored to the infant's needs.

Formula Feeding Risks

Absence of protective antibodies: Limited immune protection.
Importance of proper preparation and handling: To prevent contamination and health issues.
Risks of contamination and health issues: Improper formula use can lead to health problems.

Feeding Guidelines

0-6 months: Exclusive breastfeeding or formula feeding.
7-12 months: Introduction of solid foods while continuing breastfeeding/formula.

Nutritional Needs and Important Nutrients

Nutritional Requirements

Overview of caloric needs in infancy: Infants have a high caloric need for growth and development.
Role of breast milk and formula: Meet the infant's nutritional needs during the first year of life.

Important Nutrients for Growth and Development

- Sources: breast milk, formula, and solid foods.
Calcium: Important for bone development and growth.
- Sources: breast milk, formula, and dairy products.
Whole Grains and Complex Carbohydrates:
- Benefits: Provide energy and essential nutrients.
- Examples: Whole-grain cereals, pasta, and bread.
Vitamins A, B, C, and E:
- Vitamin A: Important for vision and immune function.
- B Vitamins: Essential for energy metabolism and brain development.
- Vitamin C: Antioxidant role and important for skin health.
- Vitamin E: Cellular protection.
- Sources: Variety of fruits, vegetables, and fortified foods.
High-Fat foods:
- Importance: Needed for brain development.
- Sources: Whole-milk dairy, avocados, and cooking oils.
Iron: Important for oxygen transport and energy levels.
- Sources: Fortified cereals, meat, poultry, fish, eggs, and legumes.
Omega-3 Fatty Acids (DHA):
- Role: Crucial for brain development and cognitive function.
- Sources: Fatty fish, flaxseed, and DHA-enriched foods.
Fluids:
- Hydration needs in infancy: Infants require adequate fluid intake.
- Transition to solid foods: Introduce water as an alternative beverage.

Feeding Techniques and Infant Formula Composition

Recognizing hunger cues:
- Behavioral signs: Crying, rooting, and sucking motions.
- Differences between breastfed and formula-fed infants: Breastfed infants may exhibit different hunger cues compared to formula-fed infants.

Regulatory Considerations

Executive Order 51, 1986 (Philippines): National Code of Marketing Breastmilk substitutes.
- Goals: Promote breastfeeding, ensure safe nutrition, and regulate the marketing of breast milk substitutes
- Promote breastfeeding as the ideal infant feeding practice.
