Study Notes

Breast Milk: The Gold Standard of Infant Nutrition

Breast milk is considered the optimal source of nutrition for infants, offering numerous health benefits.
Provides enhanced immunity, protecting infants from infections and diseases.
Linked to a lower risk of several chronic diseases in later childhood and adulthood, such as:
- Type 1 and type 2 diabetes mellitus
- Certain cancers (lymphoma, leukemia, and Hodgkin disease)
- Hypercholesterolemia, obesity, and asthma.

Nutritional Composition of Breast Milk

Composed of proteins, fats, carbohydrates, vitamins, and minerals, with variations based on the infant's needs, lactation stage, time of day, and maternal diet.
Each feeding provides different types of milk:
- Foremilk: Low-fat milk at the start of feeding.
- Hindmilk: Higher fat content milk obtained later, may influence appetite regulation.

Changes During Lactation

Transitional milk evolves into mature milk, showing notable changes:
- Immunoglobulin and protein levels decrease.
- Lactose, fat, and total caloric content increase.
- Water-soluble vitamins increase, while fat-soluble vitamin levels decrease, adapting to the growing infant's nutritional needs.

Key Constituents of Breast Milk

Contains approximately 200 different substances, categorized into:
- Macronutrients: Fats, proteins, carbohydrates.
- Micronutrients: Vitamins and minerals.
- Other nutrients: Nucleotides and carotenoids.

Infant Feeding Considerations

Certain conditions may prevent breastfeeding:
- Active untreated tuberculosis.
- Presence of herpetic lesions on breasts.
- Use of antimetabolites or chemotherapeutic agents.
Awareness of potential risks and contraindications is crucial for breastfeeding mothers.

Breast Milk: The Gold Standard of Infant Nutrition

Breast milk offers enhanced protection against infections and chronic diseases.
Provides essential nutrients that support gastrointestinal and immune system function.
Promotes neurodevelopment in infants.

Colostrum

First milk produced in the early days post-birth, yellowish and thick in consistency.
Contains high protein, lower carbohydrates, and minimal fat compared to mature breast milk.
Rich in fat-soluble vitamins and minerals.
Contains increased levels of immunoglobulin A (sIgA), oligosaccharides, and lactoferrin, aiding in infection protection.

Composition of Breast Milk

Consists of proteins, fats, carbohydrates, vitamins, and minerals, varying based on the infant's needs.
Changes during different lactation stages, times of day, maternal diet, and throughout a single feeding.
Transitional milk is produced from approximately seven to ten days postpartum until around two weeks postpartum.

Macronutrients in Breast Milk: Protein

Protein is vital for tissue growth, repair, and maintenance.
Mature breast milk contains approximately 10–12 grams of protein per liter, ensuring low renal solute load.
Proteins in breast milk are highly digestible and absorbed more efficiently than cow's milk proteins due to their nutritional quality.
Contains two primary protein types: whey and casein.

Macronutrients in Breast Milk: Fat

Serves as a carrier for fat-soluble vitamins and produces hormones contributing to satiety.
Acts as a concentrated energy source and provides optimal energy storage.
Unique fatty acid profile includes long-chain polyunsaturated fatty acids (LCPs), specifically DHA and AA.
Continuous supply of LCPs is critical for visual and cognitive development during the first year of life.

Micronutrients in Breast Milk: Vitamins and Choline

Vitamins function as cofactors essential in various metabolic reactions.
Choline is necessary for brain development and the synthesis of phosphatidylcholine for cell membranes.
Important vitamins in breast milk include Vitamin A, Vitamin C, Vitamin D, Vitamin E, and Vitamin K.

Breast Milk: The Gold Standard of Infant Nutrition

Breast milk is recognized as the optimal source of nutrition for infants.
Breastfeeding may decrease the chances of chronic diseases like diabetes (type 1 and type 2), lymphoma, and obesity in later childhood and adulthood.
Offers enhanced immunity, which can help prevent conditions such as asthma.

Nutritional Composition of Breast Milk

Breast milk comprises protein, fat, carbohydrates, vitamins, minerals, and other essential nutrients.
The composition adapts to meet the changing needs of the infant and can vary by lactation stage, time of day, and maternal diet.
Nutritional content may differ even within a single feeding session.

Macronutrients in Breast Milk: Fat

Fat constitutes approximately 50% of the caloric content in breast milk.
The fat is specifically structured for effective digestion and absorption, with about 90% being digestible.
Presence of bile salt-stimulated lipase aids in fat digestion.

Macronutrients in Breast Milk: Carbohydrates

Carbohydrates are vital for the growth and development of infants.
Their main function is to supply energy to the body's cells.
Human milk oligosaccharides (HMOs) play a protective role by preventing infections from pathogens, viruses, and toxins.

Infant Feeding Considerations

Certain health conditions prohibit breastfeeding, such as active untreated tuberculosis, the presence of herpetic lesions on breasts, and use of certain medications like antimetabolites or chemotherapeutic agents.
