Why do spicy foods make me feel hot?
Capsaicin - the active ingredient in spicy food - binds to a special class of vanilloid receptor inside our mouth called VR1 receptors. After capsaicin binds to these receptors, the sensory neuron is depolarized, and it sends along a signal indicating the presence of spice. This process causes people to feel hot when eating spicy food.
