Hypoallergenic baby food
Hypoallergenic baby food ( HA food ) is a special baby food that is fed to a baby with a potentially increased risk of allergies . It can be given as an infant formula, if not, as recommended, breastfed exclusively with breast milk for at least four months , and also as a follow-up formula from the second half year of life.
Special features of the HA diet
The immune system recognizes a protein by its structure and can trigger an allergic reaction to foreign proteins. In HA foods, therefore, the cow's milk protein is split into small peptides by hydrolysis , which are no longer recognized as foreign by the infant's immune system. The hydrolyzate is also filtered to ensure that it is free from larger fragments. If you already have a cow's milk protein allergy, we advise against feeding HA food. Special foods that contain particularly severely split hydrolysates or a mixture of amino acids are more suitable.
Quality of the hydrolyzate
The size distribution of the peptides in the hydrolyzate is examined using a Western blot test. In particular, the proportions of the larger peptides (greater than 20 k) should be as low as possible in order to avoid an allergic reaction. All HA foods used in Germany must - in accordance with legal requirements - have proven their suitability in corresponding studies.
The presence of possible allergens in the food can be checked using test methods such as ELISA or immunoblot .
Importance of the intestinal flora
According to the latest studies, the allergy preventive effect of breast milk is based not only on the species-specific protein structure, but also on the content of prebiotic breast milk oligosaccharides . The content of breast milk oligosaccharides is around 1 g / 100 ml, almost as high as the protein content in breast milk. The breast milk oligosaccharides ensure a healthy bifidus-dominant intestinal flora , which seems to have a protective effect on the occurrence of allergies and infections .
For example, the intestinal flora of atopic children contains a higher number of potentially pathogenic germs such as clostridia and a lower number of health- promoting bacteria such as bifidus bacteria than in non-atopic children.
In order to positively influence the intestinal flora, some baby foods currently contain probiotics or prebiotics . The study situation regarding the benefit of probiotic bacteria for allergy prevention, however, provides a mixed picture and rather shows effects in the treatment of atopic dermatitis . The properties of the probiotics are also always to be considered strain-specific and not transferable. The allergy preventive effect of certain prebiotics, however, has been shown in studies.
Studies show that infants develop a bifidus-dominant intestinal flora, as in breast-fed children and non-atopic people, when they are given an infant formula with a specific prebiotic mixture of galactooligosaccharides (GOS) and fructooligosaccharides (FOS). In the latest studies, they also show a very good effect in terms of allergy prevention and the reduction of infections. In particular, the occurrence of atopic dermatitis could be significantly reduced in the studies through the use of infant formula with prebiotics.
In one of these studies, 206 allergy-prone infants up to the age of six months were given either an HA diet with prebiotics or the same diet with a placebo. At six months of age, the incidence of atopic dermatitis in the prebiotic group had decreased by 50 percent compared to the control group. Even at the age of two, atopic dermatitis occurred only half as often in the prebiotic group.
In a further study of 1,187 children without a predisposition to allergies, which was carried out with a new mixture of prebiotic, 5.6 percent of the children in the prebiotic group suffered from atopic dermatitis after one year. This value was in the range of the comparison group of breastfed infants. In the group without the prebiotics in the baby food, the figure was significantly higher at 9.4 percent.
Doubtful benefit
Australian researchers question the benefits of HA baby formula. In a study of 620 infants with a high risk of allergies, they compared the effect of baby food made from cow's milk and hypoallergenic food. They published the results in the Journal of Allergy and Clinical Immunology .
