What is spicy? Why do some people like spicy food, but some people can’t eat spicy food? What kind of characteristic is it?
The spicy essence is actually a pain.
Because our tongues are covered with dense taste buds, these taste buds are distributed in the bulges similar to small “nipples”, and these small bulges are closely connected with the nociceptive pain fibers in our tongue.
Everyone knows that our taste buds can only respond to one of the “sweet, sweet, bitter and spicy”. When the capsaicin in the pepper enters our mouth and is accepted by the taste bud that can respond to the spicy taste, it is harmful The pain fiber received a stimulus, so we had such a spicy feeling.
The reason why some people cannot eat spicy food is that their taste buds and the nociceptive pain fibers connected to them are too sensitive. As long as they eat spicy food regularly, the taste buds and nociceptive pain fibers will gradually become dull. I can eat spicy more and more.
