The relationships among the effect of carbohydrates on blood glucose, appetite, food intake, mood and memory

grantor: University of TorontoThe hypothesis of this research was that there is a relationship between the effect of carbohydrates on blood glucose and their effects on appetite, food intake, mood and memory. Experiment 1 examined the effects of 300kcal preloads of sucrose, polycose, amylose and amylopectin on blood glucose over one hour. Experiment 2 examined the effect of the same treatments on appetite, food intake, mood and memory. The final experiment examined the relationships among the glycemic response to sucrose, polycose, glucose, fructose/glucose mixture and sucralose preloads and their effects on appetite, food intake, mood and memory. A relationship was observed between the high glycemic carbohydrates, sucrose, polycose and glucose and decreased mealtime energy intake at one hour. No relationship was found between the glycemic response to carbohydrates and mood and memory. Sucrose preloads were found to improve memory performance. It is concluded that the glycemic response to carbohydrates is associated with their effect on appetite and food intake but not mood and memory.M.Sc
