Each symptom was ranked on Likert scale, as never (score =0), rarely (score=1), moderate (score=2) and severe (score=3)<br>2. Immune response (milk-specific IgE antibodies), assessed by milk-specific IgE blood serum test. Blood serum sample was performed by the laboratory assistant as follows: blood samples were taken within a range of 12 hours before starting the intervention and after the intervention; laboratory assistant takes 5 ml of venous blood; samples were analyzed by ELISA (enzyme-linked immunosorbent assay) technique in the laboratory<br>
