When visits to various doctors did little to relieve the allergies Steve Kuhnau was suffering from, the nurse began reading up on nutrition, hoping a change in diet would help his symptoms. Once he began eating fresh foods and cutting fat out of his diet, Kuhnau started feeling better. His next task was to find a way to tackle the midday fatigue caused by hypoglycemia. Using his nursing expertise and the drink mixing experience he gained as a soda jerk in high school, Kuhnau began experimenting with high protein drinks. The resulting product combined fresh fruits, vitamins and other supplements and inspired the creation of Kuhnau's company, Smoothie King. Each Smoothie King store sells smoothies and a variety of vitamins, minerals, low fat snacks and nutritional supplements.
