Frequently Asked Questions (FAQs)
Why is mother’s milk considered a dynamic fluid?
Mother’s milk is considered dynamic because its composition changes over time, adapting to the infant’s evolving needs. The milk produced in the first few days after birth (colostrum) is rich in antibodies, while the mature milk produced later is higher in fat and calories. Furthermore, the composition changes within a single feeding, with the milk at the beginning being more watery and the milk at the end being richer in fat.
What are milk oligosaccharides, and why are they important?
Milk oligosaccharides (HMOs) are complex carbohydrates that are abundant in human milk. They are not digested by the infant but instead serve as prebiotics, feeding beneficial bacteria in the gut. HMOs also have direct antimicrobial and anti-inflammatory effects, contributing to the development of a healthy gut microbiome and immune system.
Does pasteurizing or freezing mother’s milk affect its therapeutic properties?
Pasteurization can reduce the levels of some bioactive components in mother’s milk, such as certain enzymes and antibodies. Freezing can also affect the structure and function of some milk components. However, both processes are generally considered safe and effective for preserving milk for later use, especially when immediate breastfeeding isn’t possible. Optimization of these processes is an area of ongoing research.
Can milk from a milk bank be used for therapeutic purposes?
Yes, milk from milk banks can be used for therapeutic purposes, particularly for premature or ill infants who are unable to receive their own mother’s milk. Milk banks screen donors and pasteurize milk to ensure safety. However, the nutritional and bioactive properties of donor milk may vary depending on the donor and processing methods.
Are there any risks associated with using mother’s milk for therapeutic purposes?
While generally safe, there are potential risks associated with using mother’s milk for therapeutic purposes. These include the risk of transmitting infectious diseases if the milk is not properly screened and processed. Allergic reactions are also a possibility, although rare.
