Hungry to eat, more adverse reactions
There are certain rules in the mechanical and chemical digestion activities of human gastrointestinal tract. When you feel hungry, usually after the stomach is completely empty, the nervous system feeds back to the brain, and then sends out the order to eat. If you eat at this time, in the long run, the digestive system and organs of the whole body will produce a series of adverse reactions.
The secretion of digestive enzymes varies at different times of the day, and it has a lot to do with the nature of the diet. For example, fat is difficult to digest, while sugar is easier to digest. When starvation, the secretion of digestive enzymes is decreased, and it is easy to indigestion. For a long time, it will increase the burden of gastrointestinal tract, leading to obesity, gastritis, gastric ulcer, gastroptosis, and colorectal cancer.
Feel hungry after eating, generally eat very quickly, thus easy to induce hypertension, coronary heart disease, and hunger prone to hypoglycemia. Eating irregularly can also damage the metabolic balance and increase the risk of chronic diseases. The enzymes secreted by digestive organs such as liver and pancreas play the role of digestion. If the diet is not regular, it can lead to abnormal secretion and affect its normal function. When the function of digestive gland is affected, it can lead to pancreatitis, gallstones and other serious consequences.
