title: Gustatory function and dietary habits in users and nonusers of smokeless tobacco.
abstract: Nicotine and smoking may modify gustatory function or preferences and are associated with altered energy balance; however, there is no information on whether smokeless tobacco (ST) has similar effects. Evaluations of gustatory function (threshold sensitivity, perceived intensity of suprathreshold stimuli, preferences) were conducted on 28 chronic ST users and 30 nonusers after both abstaining and using ST. Subjects also maintained 7-d dietary records that included descriptions of the predominant taste qualities of foods. There were few user vs nonuser differences in gustatory measures. Among nonusers, use of ST reduced perceived intensity of salty, sour, and bitter stimuli. Users reported greater alcohol intakes and lower consumption of carbohydrates, sweet foods, fruits, and grains. Chronic use of ST does not appear to have substantial effects on gustatory function but may be associated with decreased carbohydrate intakes, perhaps related to increased alcohol use and possibly because of reduced consumption of sweet-tasting foods.
