For newborns probiotics have now been widely added to infant foods, and if babies do not have obvious digestive system abnormalities or other conditions that require probiotic supplementation, there is no need to give probiotics separately. On October 24, 2011, the Ministry of Health of the People’s Republic of China published the Announcement on the Announcement of the List of Strains of Bacteria that Can be Used in Infant and Young Child Food (Ministry of Health Announcement No. 25 of 2011) for the domestic market of probiotics for infants and young children. According to the relevant provisions of the Food Safety Law and its implementing regulations, the approved strains of bacteria that can be used for food were evaluated for safety and the list of strains that can be used for infant and young children’s food was developed. The list announced the 4 types of 6 probiotics that can be used for infants and young children, Lactobacillus acidophilus, Bifidobacterium animalis, Bifidobacterium lactis, Lactobacillus rhamnosus, Lactobacillus fermentum and Bifidobacterium shortum, of which Lactobacillus acidophilus can only be used for children over 1 year old. 7 types of babies are suitable for probiotic supplementation: (1) babies with constipation; (2) babies with diarrhea; (3) babies with poor lactose tolerance; (4) babies with low immunity; (5) babies with accumulation of food and flatulence, small intestine bacterial overgrowth situation; (6) babies with bacterial and mold infections; (7) babies with complications caused by antibiotic treatment. Therefore, if your baby does not find symptoms such as the above, there is generally no need to supplement probiotics. If you need to use it, it is best to consult a nutritionist or doctor.
