The associations between serum brain-derived neurotrophic factor (BDNF) levels and several health-related lifestyle factors were evaluated in 85 healthy human subjects. Results showed that the frequency of fruit intake, exercise and television watching were associated with serum BDNF level. There was a higher serum BDNF level from the group with fruit intake five to six times per week. Subjects with moderate frequency of exercise (1-30 times of 30 min exercise per month) showed higher serum BDNF level than the group with exercise more than 30 times per month. There was a significant positive correlation between serum BDNF and the daily average watching television time in the younger age group (18-35). The result of this study supports the need for larger studies with different health-related lifestyle in healthy subjects or subjects with disorders.
