Think twice when using your microwave oven
"Although microwaves heat food quickly, they are not recommended for heating a baby's bottle" the announcement said. The bottle may seem cool to the touch, but the liquid inside may become extremely hot and could burn the baby's mouth and throat. Also, the buildup of steam in a closed container such as a baby's bottle could cause it to explode. "Heating the bottle in a microwave can cause slight changes in the milk. In infant formulas, there may be a loss of some vitamins. In expressed breast milk, some protective properties may be destroyed." The report went on. "Warming a bottle by holding it under tap water or by setting it in a bowl of warm water, then testing it on your wrist before feeding, may take a few minutes longer, but it is much safer."
Valentine asked himself:
If an established institution like the University of Minnesota can warn
about the loss of particular nutrient qualities in microwaved baby formula
or mother's milk, then somebody must know something about microwaving
they are not telling everybody.
