Americans now have the most inexpensive food available in history – and that is at least one factor fueling the obesity epidemic.
A new review summarizes what is known about economic factors tied to the obesity epidemic in the United States and concludes many common beliefs are wrong. The review, authored by Roland Sturm, PhD of RAND Corporation and Ruopeng An, PhD, of the University of Illinois at Urbana-Champaign, notes that paradoxically, rising obesity rates coincided with increases in leisure time, increased fruit and vegetable availability, and increased exercise uptake. The review appears early online in CA: A Cancer Journal for Clinicians.
