I have a habit: eating too fast. I never notice that how long it takes to eat my meal but I am always the first one to finish my meal. It is common that my stomach feel so heavy because of eating too fast. And sometimes I eat so fast that I even feel a little headache and unable to think. I know it must be a bad habit which will must do harm to my health in a long run. So today I want to learn more about the harm of eating too fast and how to change it.

First, I found a study which presents eating more quickly may be a factor in the development of Type 2 diabetes.The study is held in 2012 in Florence, Italy. Lithuanian researchers, including Lina Radzeviciene, MD, PhD, an endocrinologist asked subjects to fill out a questionnaire about how quickly they ate compared with those around them (their choices were faster, the same and slower). And what they discovered is that “participants who said that they ate “faster” were 2.5 times as likely to have type 2 diabetes as those who said that they ate “slower.”” There are 234 adults with diabetes and 468 without.
It is an observational study which shows the correlation between eating too fast and diabetes.But in this study, we may not rule out the third variables since the study is neither large enough nor randomly, the data did not consider gender, age. The subjects are all only picked in a European country and the conclusion is rely on their own answer which lacks scientific mechanism for measuring eating speed. Reverse causation seems to be impossible, but “it could be that some underlying trait, such as some hormonal effect, leads independently to both a ravenous appetite and diabetes.”
Although this study might have a lot of limitations, I found a mechanism may explain how eating too fast causes diabetes. After meals, blood sugar levels go up. If it is too high that may injure blood vessels and nerves, which will cause diabetes. And people need enough insulin to manage the carbohydrates they eat, so that it can make blood sugar in a normal level. The fast you eat,the faster sugars will get into your blood because body’s insulin do not have enough time to catch up. And it will become a negative feedback loop, which finally may cause the type2 diabetes. But as mentioned in class, mechanism is not always crucial to know and the insulin produced may be influenced by the third variables but not only the speed you eat.

Except the potential correlation between eating too fast and diabetes, there are other negative effect of eating too fast. For instance, you might eat too much because your brain need time to recognize that you had enough food. Overeat causes obesity, which has long been recognized as one of the main causes of the illnesses. So, it is time to change your eating habit, if you always found you are the first one finish meals on the table like me, maybe you should think about slowing down. Enjoy your time having delicious food and the time spent with your friends and families.
