Do My Feet Smell Like Doritos?

The video explores why feet smell, often compared to foods like popcorn or Doritos. It explains that foot odor results from sweat interacting with bacteria on the skin, particularly those that metabolize leucine to produce isovaleric acid, a compound with a cheesy odor. This compound is also used in food flavoring, linking the smell of feet to certain snacks. To reduce foot odor, regular exercise is recommended as it decreases amino acid loss in sweat.

What is the primary cause of foot odor?

• The temperature of the environment

• The type of shoes worn

• The interaction of sweat with bacteria

• The amount of exercise one does

Which bacteria are known to feast on the nutrients in sweat?

• Helicobacter pylori and Salmonella

• Streptococcus pneumoniae and Clostridium botulinum

• Staphylococcus epidermidis and Bacillus subtilis

• Escherichia coli and Lactobacillus

What compound is produced when bacteria metabolize leucine?

• Lactic acid

• Isovaleric acid

• Citric acid

• Acetic acid

What is a common use of isovaleric acid in the food industry?

• As a preservative

• As a flavor additive

• As a coloring agent

• As a sweetener

How can one reduce the amino acids lost in sweat and thus decrease foot odor?

• By exercising regularly

• By using foot powder

• By wearing thicker socks

• By washing feet more often
