 An on-site invitation to participate in the study was given to a group of 80 medical professionals who had come to attend a medical conference in Tokyo, Japan. The invitation to take part in the study was given to each member in the same morning at the time of registration for the conference. The 80 subjects who responded to the invitation were asked to complete an Allergy Symptom Rating Scale. They were asked to list an approximate amount of daily sugar consumption in number of teaspoons. They were also asked to record if they had suffered from any known sugar-related problems in the past. The five volunteer-subjects with known diabetes and hypoglycemia were excluded from the study.
