Is your perceived Lactose Intolerance real?

Food aversions can result from an unpleasant experience with a food.  These aversions can last a life time even though the perceived problem has been overstated.  When an aversion is to a food that is an important source of nutrients there can be long term adverse health effects.  Milk aversion is very common.  Scientists at Purdue University conducted a study to determine if 21 days of milk drinking intervention could reverse milk aversion.  The results were that subjects with and without confirmed lactose intolerance could gradually increase their consumption of milk without any ill effects.
