Formula-fed babies grow more quickly.
Do you want a large, muscular baby? Then formula is your ticket, according to a study published in the Journal of Proteome Research by UC Davis. Researchers discovered that when five formula-fed infant rhesus monkeys were compared to five breastfed monkeys, the former developed quicker and bigger than the latter. One probable explanation is that formula includes higher protein than breast milk: human milk contains 8% protein whereas rhesus monkey milk contains 11.6 percent. At 18%, formula outperforms both.
