I have often said that if you’re fat, it may not be your fault. Recent research goes further to illustrate this point. In particular, an article published in Cardiovascular Psychiatry and Neurology (2009;2009:867041) demonstrates what happens when you take genetically identical mice and put them on different diets for three generations. The diets were equal in calories and total fat, but only differed in the ratio of omega-6 to omega-3 fats. By the third generation, the mice on the high omega-6 fatty-acid diet were considerably fatter, had higher levels of arachidonic acid (i.e. Toxic Fat) and had more damage to their organs.
