Because when you smell food it sends a signal up to your brain and that alerts you that you are now hungry. For some people it is a mind set thing. When they smell food they automatically think they are hungry, or need food.
When you see or smell nice food, your mouth may water, which is a reflex action controlled by the salivary glands. This is the body's way of preparing to eat and digest the food that has been detected.

Raccoons main senses are touch and smell. Their sense of touch is greater under water and since they rely heavily on their sense of touch, they prefer to feel the food under the water. They often dip their food in water. They do, however, produce saliva - although it is a popular wives tale that raccoons do not produce saliva - that is incorrect.
The stimulus for saliva production is usually the smell, sight, or taste of food, which activates the salivary glands. The response is the secretion of saliva into the mouth to facilitate the process of chewing and swallowing food.
Your saliva produces enzymes to break down food and your stomach has them too, but I am pretty sure that your stomach doesn't produce as much as your saliva.
You cannot voluntarily activate your spit glands. When you put food in your mouth, they automatically begin to produce saliva to aid in the digestion of food. Sometimes just thinking about eating food can allow them to produce saliva.
The salivary reflex, which is a parasympathetic reflex, leads to the secretion of saliva. This reflex is triggered by the presence of food in the mouth or by the thought, smell, or sight of food.
Yes, rabbits produce saliva.
Salivation when a hungry person smells something edible is a natural response. The body anticipates eating when it smells food and sends the message to the mouth to produce more saliva to help break down the food.
Saliva secretion is the process by which saliva is produced and released into the mouth. Examples of stimuli that can trigger saliva secretion include the sight, smell, or taste of food, as well as the act of chewing. Additionally, stress or nervousness can also lead to increased saliva secretion.
Most animals on earth have saliva glands in their mouth. When they hear, smell, or see anything that is food, this causes a reaction in the saliva glands to over- salivate, because the saliva helps break down the food, and because the body (for some reason) thinks the food is already being eaten.
