Our species is long–lived compared with other primates. Chimpanzees, for instance, have a life expectancy of about 13 years versus 78.5 years for U.S. babies born in 2009 (Pringle 2013). Why such a big gap? 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.Read More
Fresh Insights on Fat
Fat tissues secrete proteins that influence diet and metabolism. What the latest science means to fitness pros.
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).Read More
