Understanding Foot Odor

The video explores why feet smell, often compared to foods like popcorn and Doritos. Foot odor is caused by sweat interacting with bacteria on the skin, producing isovaleric acid, which has a cheesy smell. This compound is also used in food flavoring. Regular exercise can reduce foot odor by decreasing amino acid loss in sweat. The video concludes with a promotion for SciShow and its perks.
