Interesting study just published has implications for premature babies and other at risk term babies. Seems like a case for more use of donor milk to me.
This microscopic image of cells shows the effects of breast milk vs. infant formula digestion. Cells are alive and healthy after the digestion of breast milk (top row) with only one cell having any deformation. In contrast, the cells in the bottom row all ruptured after being exposed to the digestion of infant formula.
