Special Infant Formulas Do Not Protect Against Allergy Or Asthma
Many parents worry that their baby is at risk of asthma, allergies or type 1 diabetes could use special cow’s milk formulas which states that reduce risk. But a new review of the data on these formulas “Hydrolyzed” baby has found no good evidence that really protect children from autoimmune disorders.
“We found no consistent evidence to support the partially or extensively hydrolyzed formula has a protective role,” concluded a team led by Robert Boyle, of Imperial College London in England.
Breast milk, the perfect food?
“Our findings are in conflict with current international guidelines, in which the hydrolyzed formula for formula-fed with a family history of allergies babies is highly recommended,” the study authors added.
A US expert said the finding raises questions about the usefulness of these special products of formula.
“Allergies and autoimmune diseases [such as asthma and type 1 diabetes] are on the rise and it would be very appropriate if we had a clear path to prevent them,” said Dr. Ron Marino, associate chairman of pediatrics at University Hospital Winthrop in Mineola, New York.
“Unfortunately, despite the support [to the hydrolyzed formula] by the Food and Administration (FDA). UU drugs, the data are not conclusive,” he said.
10 myths about milk
According to British researchers, many guidelines on feeding of babies around the world (including North America, Australasia and Europe) recommend hydrolysed formula milk cow instead of the standard infant formula to prevent autoimmune disorders during the first months.
Dr. Punita Ponda, assistant chief of allergy and immunology at Northwell Health in Great Neck, New York, emphasized that regarding infant feeding, breast milk is the best choice by far.
But “the main current guidelines on infant formula advise parents to think about using a hypoallergenic formula if a close relative (like an older brother or sister) has a food allergy,” he said. That was based on previous studies that supported some kind of protective effect, Ponda said.
But the UK team found no consistent evidence to support the recommendations by the review published March 8 in the journal BMJ.
In the study, the team Boyle observed data together 37 studies involving more than 19,000 participants and were conducted between 1946 and 2015.
The researchers found that babies who were fed with hydrolyzed formula milk cow did not have a lower type 1 diabetes risk of asthma, allergies (such as eczema, hay fever and food allergies) or which they were fed human breast milk or standard cow’s milk formula.
The researchers also found no evidence to support the claim that FDA hydrolyzed formula may reduce the risk of eczema (skin disorder) or other conclusion that the hydrolyzed formula may prevent allergy to cow’s milk approved.
Both Marino and Ponda believe that based on the new report, it may be a good time to review the guidelines recommending hydrolysed formula.
“It is interesting that this [review] also have found a conflict of interest and bias in many published studies” that supported the effectiveness of hydrolyzed formulas, Marino said.
What is your opinion? “Most children are more likely to have a healthy life if they are breastfed,” Marino said.
Ponda agreed that “it may be necessary to revise the current recommendations.” “Even if you use these formulas is not harmful, are often more expensive and difficult to find in stores,” he added.
