  10. Spicy Food Explanation What creates the heat/pain we feel when we eat spicy food? • Chemicals in: ginger pepper onions • Stimulate heat - pain receptors directly, simulating the experience of heat

  11. What about Cool Mint? • Mint is a flavor picked up by sweet, sour, bitter and salty taste buds • Mint temporarily inhibits (stops) the buds from sending a signal, including some heat nerves in the tongue • An absence of heat SEEMS to be COOLNESS.

  12. Colds and Taste • Much of taste comes from vapors that reach the nose • Smell is often confused with taste although they usually work as partners to produce TASTE! • With a cold, sensory nerves do not work properly, so you can’t smell or taste properly.

  13. Law of Diminishing Returns • The more bites you take • The more the nerves fire • Nerves get tired • Signal weakens • So ….Taste enjoyment falls • Solution: • Eat a variety of things!

  14. Now, we’ll do a Lab that Tests out These Receptors
