Abstract

The purpose of this study was to investigate the influence of mildly sweetened iced tea (5% sugar concentration) and highly sweetened iced tea (20% sugar concentration) on the further desire of young adults to eat something sweet (cookies). The eating behavior of the subjects could lead to a better understanding of the nature of the specific appetite for sweets and provide more information as to how to achieve satiation. The null hypotheses were: I. There is no effect of the sugar concentration of the iced tea, sex, and body weight of the subjects on cookie consumption, and there is no interaction of the variables. II. In normal weight females and males, there is no effect of the rating of the cookies on cookie consumption in (a) condition I (5% sugar concentration), (b) condition II (20% sugar concentration), and there is no interaction of the variables sex and cookie rating. Ninety-six students with an average age of 18 to 20 years were selected from a Home Economics class on the basis of weight category and sex. They were assigned to four experimental groups: female - normal weight, obese; male - normal weight, obese. Highly and mildly sweetened iced tea and date- oatmeal cookies were used as test foods. Two testing procedures were employed, each student participating in both. At one time the subject received the highly sweetened iced tea, the next time the mildly sweetened iced tea, before the cookies were offered to him. The order of procedure for each subject was assigned randomly. During the testing time, the students filled out the evaluation forms. Each student's cookie consumption was recorded and later analyzed according to his sex, body weight, and cookie rating. Analysis of variance was used to test null hypotheses I and II. A significance level of less than 0.05 was anticipated for rejecting the null hypothesis. It was found that the sugar concentration of the iced tea as well as body weight and sex did not affect cookie consumption. The only factor influencing eating behavior was the subjective rating of the cookies. All subjects, regardless of body weight and sex, ate significantly more cookies when they liked them as compared to when they disliked them. A possible explanation for these findings could be that the regulation of the appetite and satiety for sweets is primarily determined by psychological factors. More research in this field is indicated and it is hoped that this study may stimulate the interest of other workers
