There are a few nutrition options currently available to babies with cow’s milk allergy (CMA), and all of them have their own drawbacks. One option is soy formula, which uses soy as the basis for many of the nutrients usually provided by cow’s milk. Soy also contains phytoestrogen, a hormone very similar to human estrogen, and it can cause hormonal issues as the babies grow. Additionally, many babies that are allergic to cow’s milk will also be allergic to soy. Another option is hydrolyzed formula, which is cow’s milk formula that has the proteins broken down to a more digestible state. This is helpful for digestion and limiting allergic reactions, but not helpful for nutrition, as the baby is not consuming whole proteins and their stomach will get used to only consuming broken down proteins if they consume hydrolyzed formula for an extended period of time. There are also amino acid formulas, which are essentially a more extreme version of hydrolyzed formula. Rather than proteins, they contain only the amino acids that make up the proteins, like puzzle pieces that are not put together. This is extremely hypoallergenic, but much less nutritious and has a taste and odor many babies will not tolerate. Part of the reason Harmony was created in the first place was to provide a better solution for allergic babies without the drawbacks.
