Babies who suffer from allergy to soy and/or milk don’t have enough available options what to consume when it comes to the choice of formula. Actually, there are three types of hypoallergenic baby formulas which would be helpful for infants who are at a risk of having an allergy or have got it already.
1. EHFs, or extensively hydrolyzed formulas, are based either on soy or milk protein broken down using a range of methods, such as using enzymes or heat. As a result, a well-tolerated and hypoallergenic formula is created which can be consumed by a number of babies suffering from allergy to soy and/or milk. However, allergic reactions are still possible, though they are quite rare. Among EHFs we can single out Similac Alimentum Advance, Nutramigen, Peptamen and Pregestimil.
2. PHFs, or partially hydrolyzed fromulas, are supposed to be easier to digest compared to conventional ones. They may prevent the development of allergic diseases, however, formulas of this type may be the cause of allergic reactions, thus, shouldn’t be considered hypoallergenic. Among PHFs are Enfamil Gentlease, Good Start and Carnation Good Start Soy.
3. EFs, or elemental formulas, are well-tolerated by infants and children with serious food allergies, including eosinophilic esophagitis. They are manufactured from free amino acids and used to delay or prevent the onset of atopic dermatitis and food allergy in kids who are at a high risk of developing allergies. Elecare, Nutramigen AA, Vivonex and Neocate can be found among EFs.
