If you've ever eaten a spicy meal and then gone to the gym later in the day for a hard, sweaty workout, you may have noticed that other exercisers gave you a wide berth. It's not just because of your breath. Foods containing curry, garlic and various other spices are metabolized by your body to produce stinky chemicals such as sulfur, which ooze out of your pores to create a pungent body odor.
Some food ingredients such as capsaicin, the hot pepper used in Buffalo-style chicken wings, make matters worse by stimulating the nerve receptors in your mouth and tricking your nervous system into thinking that your body is outside in 90 degree F (32 degree C) heat, so that you start sweating more than usual [sources: Watson, Kosecki and Gelman]. So if you're going to indulge in a peppery, curry dish, you might want to go for a walk in the woods by yourself rather than hit the gym.
