In 2006, the University of Liverpool conducted a study where the goal was to evaluate how red meat impacted the body odor of individuals. Half of the participants kept a meat-free diet for a two week period, while the other half consumed it daily. It is important to note that all of the participants were asked to refrain from other known causes of body odor like eating garlic, drinking alcohol, and smoking.
Other non-meat foods that are known to impact body odor include curry, asparagus and cruciferous veggies (broccoli, cabbage, brussels sprouts).
At the end of the two weeks, the participants were asked to wear cotton pads under their arms for 24 hours. A testing panel then smelled the pads and rated them based on intensity and pleasantness. A month later, the study was repeated with the same participants. This time the carnivores went meat-free for two weeks and visa versa. The results in both tests showed that the red meat diet smelled more intense and less pleasant than those who did not consume meat.
