Dinner should not be eaten too late: Eating dinner early prevents disease
Medical experts recommend eating dinner early as a healthy practice. Related studies have shown that eating dinner early can significantly reduce the incidence of urinary tract stones.
The human body's peak time for calcium excretion is often 4 to 5 hours after a meal. If dinner is too late, when this peak excretion time arrives, a person is already asleep in bed. Urine then becomes retained in the urinary tract, such as the ureter, bladder, and urethra, and cannot be expelled from the body in a timely manner. This causes the calcium in the urine to continuously increase, making it easy to deposit and form small crystals. Over time, these gradually enlarge and form stones. Therefore, having dinner around 6 p.m. is more appropriate. Two, dinner should not be too greasy: A vegetarian dinner helps prevent cancer
Dinner should be predominantly vegetarian, with a focus on foods rich in carbohydrates, and the less protein and fat consumed, the better.
However, in real life, because most families have ample time to prepare dinner and eat more lavishly, this is detrimental to health. According to scientific research reports, consuming large amounts of high-protein foods like meat, eggs, and milk at dinner increases the amount of calcium in the urine. On one hand, this reduces the body's calcium stores, inducing rickets in children, myopia in adolescents, and osteoporosis in middle-aged and older adults. On the other hand, a high concentration of calcium in the urine greatly increases the likelihood of developing urinary tract stones. Furthermore, excessive protein intake that the body cannot absorb will remain in the intestines, where it can spoil and produce toxins such as ammonia, indole, and hydrogen sulfide, which irritate the intestinal wall and induce cancer.
If too much fat is consumed, it can raise blood lipids. Research data shows that people who frequently eat meat for dinner have blood lipid levels 2 to 3 times higher than those who eat a vegetarian diet. Carbohydrates can generate more serotonin in the body, which has a calming and sedative effect and is particularly beneficial for those with insomnia. Three, dinner should not be too much: A moderate dinner ensures a good night's sleep
Compared to breakfast and lunch, dinner should be lighter
In the evening, with no other activities or if the meal is eaten late, having too much dinner can cause an increase in cholesterol, stimulating the liver to produce more low-density and very-low-density lipoproteins, which can induce arteriosclerosis. Long-term overeating at dinner repeatedly stimulates the large secretion of insulin, often leading to the premature failure of pancreatic beta cells, thus laying the groundwork for diabetes.
In addition, an overly full dinner can cause the stomach to swell, putting pressure on surrounding organs. The strenuous work of the stomach, intestines, liver, gallbladder, and pancreas after a meal sends signals to the brain, causing it to become active. This activity can spread to other areas of the cerebral cortex, inducing insomnia.
