The pneumonia prevention might be effective in the smell of a black pepper.

It becomes difficult to transmit in the signal from the brain "Send off food to not the trachea but the gullet" while aging, it enters in the trachea, and food and saliva enter the trachea by mistake (It is said, "miss drinking(Goen)"). The senior citizen becomes the chance of pneumonia this Goen, and comes to develop pneumonia easily and to repeat as a result.

However, it was analyzed that it became difficult for the smell of a black pepper to prompt the discharge of the neurotransmitter in the brain that bore the reflection in the research team, and to put Goen. Meal was actually taken after "Lavender", "Nothing is smelt", and "Black pepper" were made to be smelt with health services facilities for the elderly before the meal for 105 people and 15-17 seconds the speed to which only the group of "Black pepper" swallowed food advanced in dramatic form during four seconds on the average when the swallowed reaction was examined.

The smell of the pepper associates Cshami (The brain reacts) and it is because or another has the reason do not understand. However, I was surprised to be effective that the smell of a black pepper prevented Goein, too. The pepper seems to become necessaries in the hospital and facilities related to the elderly person depending on the research in the future).
