The impact of snack and vegetable intake on body composition in young healthy subjects

抄録

Background/Objectives:Although dietary intake has been shown to affect various diseases, the effect of dietary intake on body composition remains unclear. Therefore, this study aimed to assess the effects of dietary intake on body composition. Methods:A total of 51 Japanese dietetic students (11 men and 40 women;average age:20.9±2.8) participated in this study. We assessed their body composition (i.e., muscle mass, body fat, and total body water) using the Physion MD® system. The subjects also completed an FFQg that was used to analyze dietary intake. Results:The mean body mass index was 21.09±3.28 kg/m2, the mean percentage of body muscle was 35.9±6.2%, and the mean percentage of body fat was 21.1±6.7%. The body fat percentage was negatively correlated with vegetable intake (r=-0.5872, p<0.0001) and positively correlated with snack intake (r=0.6853, p<0.0001). Conclusions:Daily dietary intake, especially intake of vegetables and snacks, was independently associated with body fat percentage in healthy subjects. This suggests that intake of vegetables and snacks has a direct impact on body composition. J. Med. Invest. 72 : 281-285, August, 2025
