A survey of 8,749 people was conducted in Great Britain to determine the percentage of those who limited or avoided consumption of cow's milk for reasons other than financial. Those who limited or avoided cow's milk consumption were further questioned to determine whether their reasons were perceived by them to relate to allergy/lactose intolerance. Of the sample population 1.47% limited or avoided cow's milk consumption for reasons that might possibly be related to allergy/lactose intolerance.
