One thing that I have noticed for years is that whatever someone consumes a lot of is evidenced by the odor of their sweat. e.g. If someone drinks a lot of beer or alcohol, they will smell like beer or alcohol unless of course that person takes care to shower a lot or use a lot of deodorant. Garlic, cabbage and other veggies, spices and herbs? Same thing, In Vietnam, we had choppers low leveling with a machine that could “sniff” out and distinguish the different smells of sweat. The Vietnamese ate a completely different diet than other forces that were on the ground so whomever was operating said machine would call and report which force was in the area of coverage. It could even distinguish between the Turks, Americans, other Asians, the British etc. all because of our cultural diets. As for me, I take so many supplements and vitamins that my pits smell like a medicine cabinet so I use a good deodorant and it’s all good until…..I hit the steam room. All the nasty stuff that’s locked into the pores comes out in the steam room so yeah, I’m a walking talking medicine cabinet for a while.
