"We repeated the same procedure a month later with the same odour donors, each on the opposite diet than before. Results of repeated measures analysis of variance showed that the odour of donors when on the nonmeat diet was judged as significantly more attractive, more pleasant, and less intense. This suggests that red meat consumption has a negative impact on perceived body odour hedonicity."
