Digested formula, but not breast milk, is toxic to cells, in vitro study finds

Digested formula, but not breast milk, is toxic to cells, in vitro study finds: Free fatty acids created during the digestion of infant formula cause cellular death that may contribute to necrotizing enterocolitis, a severe intestinal condition that is often fatal and occurs most commonly in premature infants, according to a new study. Bioengineers based their report on in vitro tests comparing the digestion of fresh human breast milk and nine different infant formulas.
