Abstract
The invention provides an edible fat product for incorporation into a formula suitable for feeding infants. The product includes certain fatty acids, namely, at least one of a C.sub.20 or C.sub.22, .omega.-6 fatty acid and a C.sub.20 or C.sub.22, .omega.-3 fatty acid, found to be present in human milk. These fatty acids are included in the product in certain defined amounts to avoid causing harmful effects on an infant fed on the product. The C.sub.20 or C.sub.22, .omega.-6 fatty acids, if present, are included in a total amount of about 0.13%-5.6% by weight of all fatty acids in the product. The C.sub.20 or C.sub.22, .omega.-3 fatty acids, if present, are included in a total amount of about 0.013%-3.33% by weight of all fatty acids in the product.
