Nutrition during breastfeeding - impact on human milk composition

Area of Science:

• Nutrition Science
• Pediatrics
• Human Lactation

Background:

• Breast milk is the optimal nutrition for infants, recommended exclusively for the first six months by the World Health Organization.
• Breast milk composition is dynamic and can be influenced by various factors, including the mother's dietary intake.
• Understanding these influences is crucial for optimizing infant nutrition through breastfeeding.

Purpose of the Study:

• To conduct a literature review assessing the correlation between a breastfeeding mother's diet and the composition of her breast milk.
• To identify specific nutrients in breast milk that are significantly affected by maternal dietary patterns.

Main Methods:

• Systematic literature review of studies investigating maternal diet and human milk composition.
• Analysis of existing research data to identify correlations for various nutrient classes.

Main Results:

• A strong correlation was observed between maternal dietary intake and the levels of polyunsaturated fatty acids (PUFAs), particularly docosahexaenoic acid (DHA), in breast milk.
• No significant correlation was found between maternal diet and the concentration of mineral elements, including trace elements like zinc, chromium, and iron, in human milk.

Conclusions:

• Maternal diet plays a significant role in determining the PUFA content of breast milk, highlighting the importance of adequate fatty acid intake for breastfeeding mothers.
• The levels of essential trace minerals in breast milk are not directly reflective of maternal dietary intake, suggesting other regulatory mechanisms are at play.
