Detailed Description
The study cities are Guangzhou, Weihai, Chengdu, Beijing, Harbin, Wuhan, Jinhua, Zhengzhou and Lanzhou.
Breast milk will be collected at 9:00-11:00 in the morning from 15 to180 days after giving birth. The nutrients (protein, triglyceride, phospholipid, oligosaccharides and probiotics) in the collected breast milk samples will be measured. These data will be used to establish the breast milk database in China. This databased will provide references for infant nutrient intake and for the formulation and revision of infant formula standards. It will also provide references for the development of new infant formula products in China.
