Pringle says vaccines, antibiotics, sanitation, and access to nutritious vegetables and fruits year round give us a huge edge over our great–ape cousins, as does our acquired ability to fight off pathogens and irritants in our environments.

By Robert Christner, MS & Len Kravitz, PhD
We've long understood that fat is the body's principal energy-storage tissue. However, it's now becoming clear that fat tissue is a major hormone-secreting organ, producing cell–signaling proteins called adipokines that play an important role in metabolism, feeding behaviors, glucose regulation and insulin control (Singla, Bardoloi & Parkash 2010; Al–Suhaimi & Shehzad, 2013).
