I understand the question! Many of these formulas promote carrying DHA while being non-fat! We all know that most cholestorols and high fat foods already contain DHA naturally! These formulas are meant to be substitutes or supplements to the naturally occurring source of DHA and Omega-3. Ideally, an infant should be continually feeding on its mother for all of the nutrients and “healthy” fats that will allow for proper development. One very good benefit is that some of these formulas are all-milk based so there is at least some highly-soluble, naturally occuring, amounts of DHA that are inherently present.
