“It was once thought that the nutrients and bioactives in human milk were transferred directly to the nursing infant in a linear manner”. “Now there is considerable evidence that

The urea nitrogen connection is important in ruminant animals, and plays a critical role in infant nutrition.
According to Sela “We want to characterize mechanistically what is going on within the microbes themselves. We’re trying to reduce the system into its components and then paint the larger picture once we understand the smaller aspects of it,”
