1. When we eat, we first chew. Our teeth grind down the food into small particles so it will be easier to digest in the stomach. Saliva, which contains the enzyme amylase, is secreted in the process. This enzyme aids digestion by changing starch in food into maltose.
2. Different people have different eating habits; some do not chew their food thoroughly and wolfed it down, while others chew their food well before swallowing it. It is obvious that the latter enables easier digestion and absorption of nutrients by the body. This is because when food is sufficiently chewed, it is grinded down into small particles and mixed thoroughly with saliva before entering the stomach. Also, by chewing slowly one can better notice nuances in taste and flavor.
3. In addition, the act of chewing sends a signal to the satiety center in the brain’s hypothalamus inducing a feeling of fullness, controlling appetite and preventing overeating, thus achieving weight loss. On the contrary, if there is no sufficient chewing, there may be no signal sent to the satiety center of the brain, hence although one may have eaten a lot, one may not feel full. This may cause overeating, increase in appetite and as a result, excessive nourishment leading to obesity.
4. Although it may appear that wolfing down food or chewing it well is just a matter of how you chew, but they have two different effects. So, in order to lose weight and to have better digestion, chewing food well is the best way to eat. It enables us to feel full after eating a small amount of food.
5. Below the thalamus are the feeding centre and satiety centre. In particular, the satiety centre has the ability to regulate the amount of food we eat. This centre regulates eating according to the metabolism rate of energy in the body. Chewing food well is the most scientific way to eat. For those who eat hurriedly, you may wish to change the way you eat as eating too quickly affects digestion and easily leads to overeating which may result in obesity. Seems like there is a lot to learn about eating, doesn’t it?
