The human body, when looked at in enough detail, is truly miraculous. A study in 2009 found that human breast milk actually varies its composition throughout the day, sending circadian signals to the infant to help regulate its biology appropriately.

Among many different nutritional factors, the milk varied in composition by providing more cortisol in the daytime and more melatonin at night. Another study has found that, when the baby is ill, the mother's breast milk provides more immune factors to help the infant body to fight off the infection.

Such amazing findings have wide-ranging implications (not the least of which questions the value of infant formula in providing all the 'nutrition', or more accurately information, the baby needs).

Join us on this episode of Objective:Health as we explore the amazing benefits of breast feeding.
