Results of Body Composition Improvement by High Caloric-Tofu Intake—At the Start of the Experiment, at the End, and Six Months after the End for the Case of Adolescents

摘要

The previous paper by Naomi Katayama et al. reported the effect of high caloric-tofu on the young people [1] and elderly people [2]. And the body composition was improved by elderly people and young people eating high caloric-tofu for 2 months. In both paper reports, both participates decreased body fat and increased body protein. Therefore, in this research, we decided to investigate young people who can keep their body composition after six months to stop eating high caloric-tofu. The ten young people (9 male, one female: from age 19 years old to 22 years old) who submitted the written consent of the subject participated in this study. We performed the gene analysis (β3AR, UCP1,β2AR) of the subject. The subject lived a normal life every day. The subject had eaten two caloric-tofu a day. A caloric-tofu has 100 kcal. The subject participated in a study for two months. As for the subject, body composition was measured on the first day and the last day of the study. As a result, skeletal muscle rates of eight people increased slightly, and body fat rate decreased slightly. However, two people did not change neither the skeletal muscle rate nor the fat rate. Body composition of the eight participants who were effective by this experiment was not kept after six months to stop this study. Six months after the end of the intervention for the participants, the body composition became worse. In this study, participants could temporarily change their behavior but could not continue this condition. It will be necessary to increase the number of participants more, and to examine it in detail in future. We also need to investigate a wide range of age groups. We thought in future that an effect might appear by doing nourishment instruction based on a result of the gene analysis.
