A recent Nature Outlook commentary summarized some cutting edge research in milk composition and lactational programming. Though not mentioned by name, the work of Drs. Katie Hinde and Erin Sullivan is highlighted:
"In rhesus macaques, sons drink milk with a higher concentration of cortisol, a hormone that modulates metabolism, even though their mothers have no more cortisol circulating in their blood than when nursing a daughter. It is unclear whether this cortisol-related sex difference has a function. But there are clues: young male macaques that consume milk containing high levels of the hormone develop bold behaviour, whereas cortisol in milk appears to have no influence on female macaque infants. Whether this has a parallel in humans is yet to be determined."
Dr. Hinde also recently published a paper (early view at Journal of Medical Primatology) with Dr. Lin Tao, a colleague of mine at the College of Dentistry at the University of Illinois at Chicago: Species diversity and relative abundance of lactic acid bacteria in the milk of rhesus monkeys (Macaca mulatta)
