點解食辛辣的食物會令人流鼻水

Most people have a runny nose when they eat hot and spicy food. This happens because those food products usually contain a natural substance called capsaicin. "Capsaicin is the ingredient found in different types of hot peppers, such as cayenne peppers, that makes the peppers spicy hot." Capsaicin is also a triggering element that gives you a runny nose.

"Capsaicin may help prevent heart disease. It may stimulate the cardiovascular system and may lower blood cholesterol levels and blood pressure. It also helps prevent clotting and hardening of arteries (atherosclerosis).

Capsaicin acts as an antioxidant, protecting the cells of the body from damage by harmful molecules called free radicals. Capsaicin also may help prevent bacterial infections.

Capsaicin may also make mucus thinner and help move it out of the lungs. It is also thought to strengthen lung tissues and help to prevent or treat emphysema."
