Introduction The Japanese diet has been associated with a healthier lifestyle and lower obesity rates. However, dietary habits may also be important. To investigate the dietary habits of Japanese people, we conducted a survey at the health check-up center of Hiroshima Kyoritsu Hospital.
Methods 305 Japanese adults who received health check-ups and participated in the questionnaire survey (conducted from January to February 2015) were enrolled. Basic information such as age, gender, body mass index (BMI) and mean arterial pressure (MAP) were recorded along with answers and analysed.
Results Participant’s age ranged from 22 to 77 years old, BMI ranged from 15.4 to 35.0 kg/m and the average MAP was 90.7 ± 14.3 mmHg. 58% of the respondents started their meals with a vegetable dish. 74% of the participants ate between 10 to 29 minutes on average. Those who skipped breakfast (19%) had significantly higher BMI than those who ate breakfast. Those who stopped eating at 80% satiety had lower BMI as well as MAP levels compared to those who ate until 100% satiety.
Conclusions The survey showed that simple practices like starting meals with vegetables, eating regular breakfast and stopping at 80% satiety were all part of the Japanese dietary habit. These dietary habits are relatively easy to follow and may contribute to a healthier lifestyle.
