Busy urban dwellers often eat casually for breakfast and lunch, making up for it all at dinner. Moreover, there's no time for activity after a big meal. So, how can one make dinner more beneficial? One: Don't eat too much for dinner: An early, light dinner helps prevent gallstones.
Having an early dinner is a healthy practice recommended by medical experts. Related studies show that eating dinner early can significantly reduce the incidence of urinary tract stones.
The peak time for calcium excretion in the human body is often 4 to 5 hours after a meal. If dinner is too late, when this peak arrives, a person is already asleep. Urine then stays in the urinary tract, such as the ureter, bladder, and urethra, and cannot be expelled in time. This causes calcium in the urine to continuously increase, easily forming small crystals that, over time, gradually grow and develop into stones. Therefore, having dinner around 6 p.m. is more appropriate. Two: Don't eat too much meat for dinner: A vegetarian dinner can help prevent cancer.
Dinner should be primarily vegetarian, rich in carbohydrates, with as little protein and fat as possible.
However, in real life, because most families have ample time to prepare dinner, they tend to have a rich spread, which is detrimental to health. According to scientific research, consuming large amounts of high-protein foods like meat, eggs, and dairy at dinner increases the amount of calcium in the urine. On one hand, this reduces the body's calcium stores, potentially triggering 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 risk 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 like ammonia and hydrogen sulfide, irritating the intestinal wall and inducing cancer.
Consuming too much fat can elevate blood lipids. Research data indicates that people who often eat meat for dinner have blood lipid levels 2 to 3 times higher than those who eat vegetarian meals. Carbohydrates can generate more serotonin in the body, which has a calming and sedative effect, making it particularly beneficial for those with insomnia. Three: Don't eat too much for dinner: 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 late, eating too much for dinner can cause cholesterol levels to rise, stimulating the liver to produce more low-density and very-low-density lipoproteins, thus inducing atherosclerosis. Consistently overeating for dinner over the long term repeatedly triggers large secretions of insulin, which can often lead to the premature failure of insulin beta cells, thus laying the groundwork for diabetes.
In addition, an overly full dinner can cause the stomach to distend, putting pressure on surrounding organs. The strenuous work of the stomach, intestines, liver, gallbladder, and pancreas after the meal sends signals to the brain, causing it to become active and spreading to other areas of the cerebral cortex, which can induce insomnia.
