2.2. Participants
CARDIOVASCULAR DISEASE, GASTROINTESTINAL DISEASE, CHRONIC DISEASES, METABOLIC DISEASE, ENDOCRINE DISEASE
The criteria for subject inclusion were: (a) delivered at full-term (≥37 weeks); (b) aged 6–24 months; and (c) delivered by C-section. We excluded those infants who had taken probiotics or prebiotics within 2 weeks before the intervention or who had taken milk powder containing probiotics or used antibiotics within 3 months before the experiment. Additionally, those who were suffering from serious acute or chronic diseases (cardiovascular disease, gastrointestinal disease, endocrine disease, immune system disease, metabolic disease, etc.) and using drugs that may interfere with the experimental results were not included in the trial. Fulfillment of the inclusion and exclusion criteria was validated by the investigator and appointed research nurse.
