the nutritional content of formulas is measured after pasteurization and processing and is very tightly monitored in the us. there is no difference between the ready-to-feed and powdered varieties in terms of calories or nutrients -- with the single exception of fluoride which is not added to ready-to-feed but is probably in the water you're using to mix the powder. ready-to-feed formulas do have a sort of "thicker" consistency but there is no difference in the food quality or calorie content. raw milk is a fad that should be abandoned. there are no health benefits and some risks are involved. .
does the extreme heat of the sterilization process cause a loss of nutrients in ready-to-use baby formula?
