This study aimed to elucidate the relationship between maternal nutrition and the quantity and composition of breast milk.
All mothers were administered sequentially, with each lasting one week, a healthy nutrition diet, a carbohydrate-rich diet, and a protein-rich diet.
Compared to the healthy nutrition diet, a statistically significant increase was observed in the levels of glutamic acid, serine, glycine, histidine, tyrosine, valine, isoleucine, leucine, and lysine in milk following the carbohydrate-rich diet (p < 0.05). In contrast to the healthy nutrition diet, the lactose content of milk decreased after the carbohydrate-rich diet and increased after the protein-rich diet (p < 0.05). Following both carbohydrate-rich and protein-rich diets, a reduction in riboflavin content in milk was observed compared to the healthy nutrition diet (p < 0.05). After the protein-rich diet, an increase in milk quantity was observed compared with the carbohydrate-rich diet (G1, p = 0.006; G2, p = 0.001). A negative correlation was found between the mothers' body weight in the third week and the amount of amino acids in their milk (r = -0.270, p = 0.037).
The results of this study indicated that the nutrient composition and quantity of human milk are influenced by maternal nutrition.
本研究旨在阐明母体营养与母乳的量及成分之间的关系。
所有母亲依次接受为期一周的健康营养饮食、富含碳水化合物的饮食和富含蛋白质的饮食。
与健康营养饮食相比，富含碳水化合物的饮食后，母乳中谷氨酸、丝氨酸、甘氨酸、组氨酸、酪氨酸、缬氨酸、异亮氨酸、亮氨酸和赖氨酸的水平有统计学显著升高（p < 0.05）。与健康营养饮食相反，富含碳水化合物的饮食后母乳中的乳糖含量降低，而富含蛋白质的饮食后乳糖含量升高（p < 0.05）。与健康营养饮食相比，富含碳水化合物和富含蛋白质的饮食后，母乳中的核黄素含量均降低（p < 0.05）。与富含碳水化合物的饮食相比，富含蛋白质的饮食后母乳量增加（G1，p = 0.006；G2，p = 0.001）。母亲第三周的体重与母乳中氨基酸量之间呈负相关（r = -0.270，p = 0.037）。
本研究结果表明，母乳的营养成分和量受母体营养的影响。
