摘要
The previous paper by Naomi Katayama et al. reported the effect of high caloric-tofu on elderly people. The body composition was improved by elderly people eating high caloric-tofu for 2 months. Elderly people decreased body fat and increased body protein. Therefore, in this research, we decided to investigate young people who can improve body composition by eating high caloric-tofu for 2 months. The twenty-two young people (19 men, 3 women: 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. A result, skeletal muscle rates of fifteen people increased, and a fat rate decreased. However, five people changed into neither the skeletal muscle rate nor the fat rate. People who were effective by this experiment were the people who had variation in β2AR, and people among whom there was not an effect were the people who had variation in UCP1. This experiment had little number of the data, but it was revealed that an intake of the caloric-tofu was more likely to help the reinforcement of the skeletal muscle mass to a participant with the variation in β2AR gene. 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.
