Does refrigerating breast milk lose nutrients?

The Nutritional Integrity of Refrigerated Breast Milk
Breastfeeding is widely recognized as the optimal source of nutrition for infants, providing essential nutrients and antibodies that support healthy growth and development. However, many parents wonder about the impact of refrigeration on the nutrient content of expressed breast milk. Does storing breast milk in the refrigerator lead to a significant loss of nutrients?
Nutrient Preservation in Refrigeration
Research indicates that while there are some changes in the nutrient composition of breast milk when it is refrigerated, it remains a highly nutritious option for infants. Breast milk can be safely stored in the refrigerator at around 40°F (4°C) for up to four days, with some guidelines suggesting it may remain viable for up to eight days under optimal conditions.
During refrigeration, certain nutrients, particularly antioxidants, may diminish. A study highlighted that breast milk loses some of its antioxidant properties when stored, although it still retains a significant amount of its nutritional value compared to formula. This loss is relatively minor and does not negate the overall benefits of breast milk.
Impact of Freezing and Thawing
When it comes to freezing breast milk, the situation is somewhat similar. Thawed breast milk is an excellent alternative when fresh milk is unavailable, as it retains much of its nutrient and antibody content. However, it does experience a slight reduction in certain qualities, particularly immune components, proteins, and enzymes. The freezing process can lead to some degradation, but the nutritional benefits still outweigh those of formula feeding.
Dynamic Composition of Breast Milk
It’s also important to note that breast milk is not static; its composition changes over time to meet the evolving nutritional needs of a growing baby. Factors such as the mother’s diet, the time of day, and the stage of lactation can all influence the nutrient profile of breast milk. This dynamic nature means that even refrigerated milk can provide tailored nutrition, albeit with some nutrient loss over time.
Conclusion
In summary, while refrigerating breast milk does lead to some loss of nutrients, particularly antioxidants, it remains a highly nutritious option for infants. The benefits of breast milk, even when stored, far exceed those of formula, making it a preferred choice for feeding infants. Parents can feel confident in using refrigerated breast milk, knowing that it continues to provide essential nutrients and support for their baby’s health.

Does breast milk lose nutritional value after 6 months?

After 6 mo, breast milk alone may be insufficient to meet an infant’s vitamin B-6 requirements (1).

Is refrigerated breast milk as good as fresh?

Fresh breastmilk contains the most active anti-infective properties, followed by refrigerated breastmilk, and then frozen breastmilk. Unrefrigerated fresh milk may be left at room temperature of 77°F (25°C). But it must be used within 4 hours.

What is the 5 5 5 rule for breast milk?

Something I recommend to moms is the 5-5-5 rule. Try and use milk within five hours at room temperature, five days in the fridge, and by five months in the freezer.

At what temperature does breast milk lose its nutrients?

104 degrees Fahrenheit
According to this study by Sharron Bransburg-Zabary, breastmilk should not be overheated to temperatures higher than 104 degrees Fahrenheit (40 degrees Celsius), otherwise it could compromise the nutrient quality.’);})();(function(){window.jsl.dh(‘sXVoZ-vRIc-Ki-gPztSm4Qw__31′,’

Does refrigerated breast milk have antibodies?

It contains an optimal combination of proteins, vitamins, carbohydrates, fats, and antibodies to promote growth and support the immune system. When a mother produces more milk than a baby needs, it can be refrigerated or frozen for use later.

How do you warm up breast milk without losing nutrients?

Pour very warm (not boiling) water in a mug or bowl. Place sealed bag or bottle of breast milk in the bowl of warm water. The milk should be kept in a sealed container for warming. Leave the milk in the warm water for 1-2 minutes until breast milk reaches desired temperature.

Does refrigeration damage breast milk?

Breast milk is best stored in the back of the refrigerator (39°F or 4°C), where there are fewer temperature fluctuations. It is best to use refrigerated breast milk within 4 days. To warm breast milk from the refrigerator: Place the bottle in a bowl of warm water or run it under warm water.

Can babies drink cold breast milk?

Breast milk does not need to be warmed. It can be served room temperature or cold.

Does cold milk upset baby’s stomach?

No evidence supports the claim that cold formula can cause any discomfort to your baby. If your baby doesn’t show discomfort and happily finishes their bottles, there is nothing to worry about. The American Academy of Pediatrics has never stated against feeding your baby at room temperature or cold milk.

Does breastmilk lose nutrients reheated?

Human milk is a living fluid. Microwaving breast milk can destroy valuable immunological components. Microwaving at high temperatures causes a marked decrease in anti-infective properties. Overheating during the warming process causes denaturation and inactivation of milk’s bioactive proteins and decreases fat content.
