Ultra-processed foods (UPF) and minimally processed foods (MPF) consumption are differentially connected to adiposity and possibly body composition. Phase angle (PhA) originates from bioelectrical impedance analysis (BIA) and is connected to cellular health. This study is the first to investigate associations between UPF/MPF consumption and PhA.
A cross-sectional study was conducted. Anthropometrical and BIA were performed. The Hellenic Physical Activity Questionnaire was used for physical activity evaluation, while a validated FFQ was used for dietary assessment. UPF and MPF intake (% energy) were determined according to the NOVA system. Partial correlation coefficients of PhA and dietary variables were assessed after multi-adjustment.
Students were recruited ( 151, 114 women).
University.
Median and interquartile range (IQR) of PhA were 5·5° (5·1-6·4°) in the total sample, 6·8° (6·1-7·3°) in men and 5·3° (5·1-5·9°) in women ( < 0·001). The median and IQR for UPF consumption was 13·7 (8·1-33·4) % in the total sample, 23·8 (8·1-70·5) % in men and 12·9 (8·1-27·5) % in women ( < 0·001). The mean (sd) of MPF consumption was 60·2 (sd 15·7) % for the total sample, 59·1 (sd 16·4) % for men and 60·5 (sd 15·6) % for women ( = 0·720). The consumption of UPF was negatively (rho = -0·267, = 0·002), while the consumption of MPF was positively (rho = 0·218, = 0·010) associated with the PhA, after adjustment for age, sex, BMI and physical activity.
PhA relates inversely to UPF and positively to MPF consumption. The observed associations possibly reflect the effects of diet on cellular health and in turn PhA.
超加工食品（UPF）和最低限度加工食品（MPF）的消费与肥胖和可能的身体成分不同有关。相位角（PhA）源自生物电阻抗分析（BIA），与细胞健康有关。这项研究首次调查了 UPF/MPF 消费与 PhA 之间的关联。
进行了一项横断面研究。进行了人体测量和 BIA 测量。使用希腊体力活动问卷评估体力活动，而使用经过验证的 FFQ 评估饮食。根据 NOVA 系统确定 UPF 和 MPF 的摄入量（能量%）。在多调整后评估 PhA 和饮食变量的偏相关系数。
招募了学生（151 名，114 名女性）。
大学。
总样本中 PhA 的中位数和四分位距（IQR）为 5·5°（5·1-6·4°），男性为 6·8°（6·1-7·3°），女性为 5·3°（5·1-5·9°）（<0·001）。总样本中 UPF 消费的中位数和 IQR 为 13·7（8·1-33·4）%，男性为 23·8（8·1-70·5）%，女性为 12·9（8·1-27·5）%（<0·001）。总样本中 MPF 消费的平均值（标准差）为 60·2（标准差 15·7）%，男性为 59·1（标准差 16·4）%，女性为 60·5（标准差 15·6）%（=0·720）。UPF 消费与 PhA 呈负相关（rho=-0·267，=0·002），而 MPF 消费与 PhA 呈正相关（rho=0·218，=0·010），调整年龄、性别、BMI 和体力活动后。
PhA 与 UPF 呈负相关，与 MPF 呈正相关。观察到的关联可能反映了饮食对细胞健康的影响，进而影响 PhA。
