Sugars in infant formulas pose risk to babies with inherited metabolic disorder. Babies with inherited intolerance of fructose face a risk of acute liver failure if they are fed certain widely available formulas containing fructose, pediatricians and geneticists are warning. Baby formula manufacturers should remove fructose or sucrose, or explicitly label their products to allow parents to avoid those sweeteners if necessary, the doctors say. Source 4p.
Why even put sugar in formula its not like an infant is born with sugar addiction. While I understand that there is a need to flavor something infants need as close to natural as possible. Remember, ideally ts just mom's breast milk and all the goodness of that is what a newborn needs.
