This winter I was running on a diet rich in eggs (30/week) adn butter () 0.4kg/week. For me that caused high cholesterol (numbers here http://paleohacks.com/questions/109204/ldl-cholesterol-doubled-from-pre-paleo#axzz1tJ4wRMD1). During this period I experienced none of the seasonal colds and flues which I did have the winters before.
3weeks after I halved eggs and stopped using butted the colds andflues are back with full force.
Could there be link or is it a coincidence?
