Compared with the intake of commercial vegetable juice , the intake of fresh fruit and komatsuna ( Brassica rapa L. var . perviridis ) juice mixture reduces serum cholesterol in middle-aged men : a randomized controlled pilot study . BACKGROUND Vegetables and fruits are rich in vitamins , minerals and , dietary fiber and contribute to the prevention and improvement of obesity and metabolic syndrome . However , inadequate intake of vegetable and fruit is a concern in Japan.We therefore produced a juice mixture of fresh fruit and komatsuna ( Brassica rapa L. var . perviridis : B. rapa ) with the aim to investigate the effects of this juice mixture on anthropometric data , blood parameters , and dietary intake differences . METHODS This study was performed as a single blind and randomized controlled trial . Subjects were 16 men ( mean age , 46.4 ± 7.1 years ) , and they were divided into two groups ( control group and intervention group ) . The intervention group consumed the juice mixture of fresh fruit and B. rapa . The control group consumed commercial vegetable juice . Subjects consumed juice twice a day throughout the weekday , for 4 weeks . We prepared both juices with an equivalent energy balance . RESULTS Weight and body mass index ( BMI ) of the control group after 4 weeks were significantly increased compared with baseline values . Serum total cholesterol ( T-Chol ) and low-density lipoprotein cholesterol ( LDL-Chol ) of the intervention group after 4 weeks were significantly reduced compared with baseline values . Furthermore , intake of total vegetables and fruits were significantly increased compared with baseline values in both groups . CONCLUSIONS Both vegetable juices contributed to improved intake of total vegetables and fruit . Compared with the intake of commercial vegetable juice , the intake of fresh fruit and B. rapa juice is highly effective in reducing serum cholesterol . Short-term intake of fresh fruit and B. rapa juice was shown to enhance cholesterol metabolism .
