The Centers for Disease Control and Prevention (CDC) recommends storing breast milk in the back of the refrigerator rather than in the door, as the temperature in the door can fluctuate more. It is also important to use clean, sterilized containers and to label them with the date and time of expression. Breast milk should be refrigerated as soon as possible after expression, and should be used within 24-48 hours for optimal nutrient content.
It is worth noting that while refrigeration may cause a decrease in certain nutrients, breast milk still remains one of the most nutritious and beneficial food sources for infants. Even with some loss of nutrients, refrigerated breast milk still provides a wide range of essential vitamins, minerals, and antibodies that are crucial for the baby’s health and development. The benefits of breastfeeding outweigh any potential nutrient loss due to refrigeration.
In conclusion, refrigerating breast milk can lead to a loss of certain nutrients, particularly vitamin C and other heat-sensitive nutrients. However, following proper storage guidelines can help minimize nutrient loss and ensure that breast milk remains a valuable source of nutrition for infants. If you have any concerns or questions about refrigerating breast milk, it is always best to consult with your healthcare provider or a lactation specialist.
