An article in Bloombergbusinessweek (Nov 28, 2011) describes the quandry faced by Samoa, which was forced to drop its ban on turkey Tails, the 78% fat content part of the turkey.  Obesity is rampant in Samoa, with the fatty imports being cheaper food sources than the traditional diets.  But World Trade Organization entry for Samoa requires lifting the ban on fatty food imports, permitting import taxes instead.  How should individual countries assess the health impact of consumer choice of fatty foods vs he trade benefit of open borders ? Should subsidies of local foods be the approach to manage this tradeoff ? Should developed country exporters voluntarily restrict exports of unhealthy foods not consumed by their own population?
