Lactose Absorption Last example also concerns interaction between nutrition and health, but instead of an Amerindian staple, we look at a staple of Northern Europeans -- milk Many Europeans and their No. American descendants hold belief that milk is an ideal food, even for adults This belief reinforced by Dairy Association ads claiming that "Everybody Needs Milk" and "You Never Outgrow Your Need for Milk" Perhaps because of the deep historical roots of this belief and fact that most scientists = Europeans or Euroamericans, it wasn't until 1965 that scientific documentation of variation in ability to digest milk began to accumulate In the next few years, we learned that the great majority of humans not only outgrow their need for milk, but indeed their very ability to digest it!

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
