Nutrition During Lactation
Appendix C
Appendix C presents data from a complete literature survey of data on human milk composition conducted by Margaret C. Neville (University of Colorado Health Sciences Center, personal communication, 1990). References were included if they presented data for milk composition by actual duration of lactation, but the data vary in accuracy. Nutrients included are those analyzed by Dr. Neville and colleagues.
