The peak of calcium excretion is usually 4-5 hours after eating. If you eat dinner too late, when the peak of calcium excretion comes, people have gone to bed and fallen asleep, and urine will remain in the urinary tract such as ureter, bladder, urethra, etc., which will not be excreted in time, resulting in an increasing calcium content in urine and easy deposition to form small crystals. Over time, it will gradually expand and form stones.
Hazard 2 midnight snack is better. Although rich in nutrition, it also exposes another problem, that is, how to consume nutrition. According to scientific research reports, eating a lot of high-protein foods such as meat, eggs and milk at midnight will increase the amount of calcium in urine. On the one hand, it will reduce the storage of calcium in the body and induce rickets in children, myopia in adolescents and osteoporosis in middle-aged and elderly people. On the other hand, high calcium concentration in urine will greatly increase the possibility of urinary calculi. Moreover, if protein is ingested too much, it will stay in the intestine if it is not absorbed by the human body, and it will deteriorate to produce toxins such as ammonia, indole and hydrogen sulfide, which will stimulate the intestinal wall and induce cancer. Coupled with drinking, it is easier to become attached to "alcoholic fatty liver".
Hazard 3: I often like to eat supper. If I eat high-fat and high-protein food, it is easy to make the blood lipid in the human body suddenly rise. Human blood tends to maintain a high fat content at night. Eating too much at night, or eating frequently and repeatedly, will lead to a significant increase in blood cholesterol synthesized by the liver and stimulate the liver to produce more low-density lipoprotein. Carrying too much cholesterol to the arterial wall (including penile artery) has also become one of the causes of atherosclerosis, coronary heart disease and impotence. At the same time, because of the long-term satiety at midnight, it will repeatedly stimulate islets and increase insulin secretion. Over time, it will cause the function of β cells to secrete insulin to decline, or even decline ahead of schedule, resulting in diabetes. These diseases will affect sexual function and lead to a decline in sexual ability.
The harm of supper, overeating will make the stomach swell and oppress the surrounding organs. After meals, the intense work of the stomach, intestine, liver, gallbladder, pancreas and other organs will send information to the brain, which will cause the brain to be active and spread to other parts of the cerebral cortex, causing insomnia.
Therefore, the best way to maintain health is not to eat supper or eat less supper. If you really need to supplement nutrition at night, the best choice is carbohydrates, namely starch and sugar. Because this kind of food can indirectly improve the chemical reaction of the brain, make the body secrete insulin, thus playing a role in calming the nerves, especially beneficial to insomnia.
