There is very little scope for the direct examination of relationships between nutrient intake and lactational performance in women. Experimental investigations are limited to the effects of dietary supplementation in pregnancy and/or lactation. To obtain comparisons between normal and undernourished women, studies have to be performed at a community level. Studies in Cambridge, The Gambia, and elsewhere indicate that the impact of variations in nutrient intake on lactational performance is limited: over the ranges normally found in developed and developing countries milk output does not vary in relation to energy intake, and effects of nutrient intake on milk quality are restricted to increases in vitamin content after appropriate supplementation.
直接研究女性营养摄入与泌乳表现之间的关系，几乎没有什么空间。实验研究仅限于孕期和/或哺乳期膳食补充剂的效果。为了比较正常女性和营养不良女性，研究必须在社区层面进行。剑桥、冈比亚和其他地方的研究表明，营养摄入变化对泌乳表现的影响有限：在发达国家和发展中国家通常发现的范围内，乳汁分泌量与能量摄入无关，营养摄入对乳汁质量的影响仅限于适当补充后维生素含量的增加。
