[Effects of maternal food intake on the total protein, fat, lactose and calcium concentrations in human milk].

: The concentrations of total protein, fat, lactose and calcium (Ca) in human milk were measured in 68 lactating women who were 14-425 days postpartum. Relationships of those concentrations in human breast milk with maternal food intake frequency, and the amount of dairy milk intake were investigated. Quantification theory III statistical analysis was applied to analyze food intake patterns. The concentrations of total protein at 2-5 months postpartum, fat and Ca at 1-5 months postpartum were low in milk obtained from mothers with low frequency of consumption of meat, egg, dairy products and food prepared with oil, while having a high frequency of consumption of rice, vegetables, beans and seaweed. The concentration of Ca in milk from mothers who habitually had no dairy milk intake was significantly lower compared to that from mothers who had more than 300 ml intake of dairy milk per day. Lower frequency or no intake of animal food and dairy milk appeared to affect the quality of mother's milk.
