*it may be that the explosion of chronic diseases during the 20th century is now taking a toll on american life expectancy. in 2007, the cia world factbook ranked the u.s. 45th for life expectancy at birth, below countries like israel, jordan, bosnia and bermuda. future gains in life expectancy depend largely on how much we can extend life among the elderly...exceedingly difficult, when you consider that the incidence of diabetes in people over 75 is projected to increase 336% during the first half of this century.
now, i am a big fan of michael pollan and i trust his research and logic. if we aren't seeing a decrease right now, i think he suggests that a decrease could be in our near future. unless our food consumption habits change dramatically, i'm not sure we will get thru these diet related hurdles like cancer and type 2 diabetes.
